This is beyond cool!  A natural pool!

If I had kids at home, this would be a must have!

The begonia in the gutter has more flower stalks and bigger leaves even though the plant is the wall is older and has more leaves.

My plant wall has two systems.  The wall itself is a drip system.  The nutrients drip down the roots.  The gutter, however, is a flood and drain system.

This morning I was catching up on posts on WindowFarms and read a post by Ed where he has modified the bottle window farm into a flood and drain system.  Brilliant!  His post caused me to look at my wall and evaluate its health/growth in comparison to the plants in the gutter.

The begonia in the gutter is faster growing with more flower stalks and bigger leaves.  That’s pretty definite as far as supporting evidence goes.

So the moral here is, if it’s food you’re interested in growing, flood and drain is going to be more efficient/effective.

Yoyo loach

The loaches have done a wonderful job of snail removal.  It’s been over a week since I’ve seen a snail.  Prior to that, I’ve only seen two and they’ve been at the top out of the water and where the loaches couldn’t reach them.  <squish>  Wadly doesn’t like the loaches but I think they’re darn fun to watch.  He likes his slow and mild guppies.

Blossoms for the first time in over a decade.

One of the begonias in the wall has masses of blossoms. The light, the warm water temps and the consistent nutrition are really pumping out the flowers. Now the Ricinifolia Immense is joining the gang. It’s put out a blossom stalk for the first time in over a decade.

Ready to be put away

I’ve pulled my grow bed apart and gotten it stored away in the loft.  I’ve put the hydroton in barrels and buckets for the winter.  I’ve still got to pull the grow bed frame and cover the tank.  Next year I’ll try and find a nice clean 55 gallon drum (plastic) for storing the hydroton.  That’ll let me put it all in a single container.  The 30 gallon drum I’ve got just isn’t big enough on its own.

Open source window farm

Every so often I do a search on plant walls and vertical gardening to see what’s new.  This morning I ran into this.  It’s pretty cool!  But better than just the idea is the way this system works.  It is built on the airlift model.  Instead of using a pump and timer to handle delivering the nutrient rich water, the system uses an aquarium air pump.  While you can buy the whole system, they provide full instruction for a number of different models that can be made from plastic water bottles.

This is very cool.  If you’ve got a kid who needs a science project, the hanging plastic bottle farm would be a stellar undertaking.  Add an aquarium and some fish and you’ve a great “watch it work” project!

Watch this video.  Then visit our.windowfarms.org and start reading.  Fascinating stuff.

Begonia in the gutter ready to burst into bloom

I haven’t done anything about a gutter yet, and I need to . . . desperately. I’m making that a priority for tomorrow.  I’ve got two sewing machines to run up to be repaired and will handle it on the way.

All the baby fish are doing great.  I lay on the floor and watch them scoot around the tank.  Some are big enough to come out and feed with the adult fish.  I wish I could get a picture but they’re just too small to get into focus through the glass.  I end up with tiny little blobs of lighter colored stuff in a fuzzy greeny background.  Ugh.

One of the gutter begonias has blossom stalks topped with buds ready to bloom.

The big begonia is doing really well though the leaves aren’t quite to the size achieved last summer.  They’re close, just not quite there.  The wood fern is doing well.  I have  some stuff that is just limping along.  My cape primrose isn’t happy.  I’m hoping it will come around . . . it’s really slow to show happy or sad so I just have to be patient and see if the changes I’ve made help.  By late spring I should know.  I think the gloxinia is toast . . . I think it’s been totally overgrown by the surrounding foliage.

About 1/3 of the rex begonias I planted are still growing.  I think they would have done much better if I’d gotten them in the wall when all the other plants were about the same size.  Now I’ve got stuff that’s gotten huge and the rex begonias are pretty much lost in the undergrowth.  Time will tell whether they make it out of the understory.

All the philodendron, ivy and dumb cane varieties are doing tremendously well.  They really like the wall.  The hoja is doing good.  The rain forest cactus are doing fine.  The Christmas cactus bloomed a couple weeks ago, just one pretty salmon colored blossom.  It’s another plant that’s going to be lost in the undergrowth.  It just grows too slowly to stand much of a chance.  <wince>  Ditto for the epiphytes I planted last summer.  I have to stay philosophical about all this.  That’s what planting a vertical garden is all about, learning what works and enjoying the result.

It looks like the babies I thought were guppies are actually neon tetras.  They’ve finally gotten big enough to have color and shine.  Cool!  Where they were hanging out in the tank should have been a clue.  Guppies stay right at the surface until they’re big enough to not be eaten.  Tetras hang out in the middle darting in and out of the foliage and cat babies cruise the bottom.

We seem to have a steady supply of babies in our aquarium lately.  Right now we’ve got 4 adolescent guppies, at least two baby guppies hiding in the foliage and at least one, maybe two, baby catfish.  Not bad for a 50 gallon tank.

The only change I’ve made recently is in feeding.  I’ve been tossing in a cube (frozen) of blood worms twice a week.  These are gut loaded with nutritional stuff fish need and I think the addition to the diet is making a difference.

The plant wall looks great.  The light is making the difference.  I don’t have a new gutter yet.  It’s still in the planning stage.

Bog fern blooming Up close you can see the little feathers.

Remember the hooch in the jungle, the cabin by the lake? The reed sitting in the north end of the bog filter tank is now blooming.

Last year I had two reeds, a small triangular stemmed one that looked like a very small version of this one and a zone hardy one that had small crimson blossoms.  I lost the small reed and the zone hardy one has morphed into this gigantic thing that’s nearly 4 foot tall with blossoms that aren’t crimson this year.

I can safely say I have no idea what’s going on.  I plan to whack this thing in half when it dies back and give half to Mindy.

I came out this morning to a guppy in the sump.  Oops.  I fetched her out but it’s apparent I’ll need some way to prevent the little buggers from taking that ride.

Pump out at the top, wall drain at the bottom. The sump sits in the corner under the plumbing. Plant wall draining back into aquarium. The drain is supported by a hanger on the wall. It just looks like it's sitting on the The black at the top is the wall drain. The clothes pin is pinching shut the primer line.

Wadly and I got the wall connected to the aquarium last week.  The first picture is the plumbing to and from the wall.  When we move into our *real* house I won’t be able to drill holes with impunity . . . darn it.

Yesterday I got the sump connected.  I still have to paint the . . . I’m not quite sure what to call it.  It’s a collection of elbows and short pieces of pipe that takes the place of u-pipe and overflow box for controlling the level of water in the aquarium.  The portion in the aquarium will be green, the part out of the aquarium and inside the sump container will be black.  The next hot day we have I’ll pull it and paint it using Krylon Fusion.

I have the pump to push the water into the wall in the sump.  The wall drains directly into the aquarium.   I also have a very small fountain pump in the sump to keep the water circulating between the sump and the aquarium when the pump for the wall isn’t running.  I still need to clean up all the water and electric lines, running them so they won’t clutter the landscape and I still need to provide a cover for the sump to keep out debris AND I need to moderate the sound of running water in the sump.

After I manage all that I need to build a custom cover and light array for the aquarium.  And then I need to find and install the gutter for the wall for when the plant wall comes back in.  And install an overhead light for the wall.  Got the light, just don’t have enough electrical current available to run it but that should be fixed soon.

49 gallon aquarium

The larger aquarium is all set up and connected to the wall.  I’ve run 1½” black PVC pipe from the plant wall out in the sun porch through the wall to the left end of the aquarium.  The pump is in the right end with the hose for the pump using a separate hole high in the wall level with the top of the plant wall.

With the new larger tubing I had to put additional slits in the gutter stand pipe to prevent the gutter from overflowing.

I traded the pleco for a very much smaller one.  I bought five small neon tetra to give the two babies I already had a school and I bought two more catfish for a total of four.  With the guppies and adult neon tetra I have about 25 fish in the aquarium.

My next step is to get the sump built so I can maintain the water level in the aquarium when the wall is being watered, dose the wall separate from the aquarium and top the water up without adding water directly to the aquarium.

Jungle hooch

Wadly sits in the kitchen in the morning, drinking his coffee and gazing out over his domain.  This morning he said “our cabin by the lake is now a hooch in the jungle.”  It made me laugh.   The reed has gotten to be a fairly impressive size.

The first picture is what we see when we walk out the door.  The second is what Wadly sees sitting in the kitchen.  You can see why he’s calling it a hooch in the jungle.

Wadly on his beloved John Deere moving the plant wall

In the last couple weeks we’ve made a number of changes to our aquarium/plant wall setup.  We moved our plant wall outside for the summer and swapped our original 28 gallon aquarium for a larger 50 gallon one.

Yesterday I swapped our fairly large plecostomus for a scaled down model too small to eat new hatchlings and sleeping fish.  I also got two more catfish and five neon tetra about the size of the tetra babies we already had.  I think that brings our tetra count to 10.  Wadly will have to buy some more guppies to round out the pack.

I’ve still got a lot to do to the new aquarium.  I need new air hose for one of my stones, I still need to find/build a sump and I need to run plumbing through the wall to connect the plant wall to the new tank.

When we moved the plant wall out we hung it on the horizontal beam on the east end of the sun porch.  To leave it outside and still connect it to the aquarium inside the living room it was necessary to move it to the north wall.  Rather than remove the gutter and disturb all the plants again, we fastened a 2×4 to the back of the plant wall and moved it with the tractor.  It was a little time consuming but very easy nothing damaged in the move.

There’s no way to get it back into the house using the tractor but I wish we could.  This last move was incredibly easy.

I’m planning the changes I want to make to our aquaponic system when the wall comes back indoors.

This time I want the water level in the aquarium to be fixed, so I’m planning to install a sump.  In reading up on sumps I ran into a good tutorial on one of the salt water aquarium sites.  What I found delightful, beyond how clear and informative the information was the author’s style.  “I once had a zebra goby that, despite my lectures, would make the trip several times a week before I finally managed to find an effective way to enforce the height restrictions on the ride.“  Part 3, sump tutorial

Wadly’s changing to a bigger tank.  The new tank is the same depth front to back but is 4″ taller and 18″ longer.  That’s a fairly significant increase in water volume.  The addition of a sump bumps the volume even further.  I will be able to have the tank heater and small circulator pump in the sump along with the larger pump required for feeding the wall.  Moving the pump and heater out of the tank will really clean up the inside which will make Wadly even happier.

Wadly’s current tank has been very successful.  Having it attached to the wall keeps the tank’s inhabitants fairly healthy and clean with little work on our part.  The tank’s health and stability are supported by the baby catfish, baby guppies and, most surprising of all, baby neon tetras we’ve had since the tank was established.  The baby tetras were jousting last night.  They’re so flashy it’s easy to see their antics from across the room.

Lorr (our son) has discovered wholesale rot under the window and into the floor and floor supports where his 60 gallon aquarium housing Carlos the turtle, two gigantic plecos and a couple really fat goldfish.  Moving the tank is a must so it looks like Carlos is coming to stay.  The big concern is keeping Carlos comfortable.  The goldies can join mine in my 100 gallon tank outside and the plecos can go to the aquarium store.

Wadly’s next day off is Tue.  We’ll drag the big aquarium out of the loft, clean and set it up for all Wadly’s fish.  We’ll leave the smaller aquarium set up to accommodate Carlos temporarily while we get is larger tank set up and up to temp.

To keep both tanks using the wall, I’m going to have to install a sump.  I haven’t done that before.  It should be a learning experience.

Wall hanging in the sun porch.

I’ve moved the plant wall into the sun porch for the next two months.  Terry wants to change his tank to a larger one and I need to solve my recurring aphid problem, so the wall’s out!

When I move the plant wall back in I’m going to make a couple changes.  I am going to mount the gutter on the room’s wall instead of attaching it to the plant wall.  Moving the plant wall with the gutter attached was not a productive act.  The way I’d built it, the gutter couldn’t be removed from the plant wall without taking the plant wall off the room wall.    The only way to set the wall down was on the gutter.  Yeah, it was ugly.  There was no permanent damage done but it was beyond messy.

The mounting system is a success.  The plant wall was easy to lift off the mounting bracket.  I’d definitely recommend using that scheme.  To hang the plant wall in the sun porch Terry used deck screws to fasten a beveled 2×4 to the horizontal support beam in the sun porch.  The wall slipped right on it with no fuss.

I’m using a temporary gutter right now made out of billboard vinyl.  It’s not bad!  The hydroton is light and takes up enough room so when the gutter is full of water it isn’t too heavy for the quick and dirty support assembly I build using 2 sticks screwed to the ends of the wall frame holding up a metal rod taped and rolled into the vinyl at the front.  The vinyl trough ends are folded up and stapled to the wall frame.  It doesn’t leak and it doesn’t add to the weight of the wall.  It’s not a permanent solution but it is a quick and dirty temporary one that works.  The drain is a threaded bulkhead fitting with a piece of plastic water pipe inserted in the top.  The water pipe has holes drilled to allow the water to drain.  The closer to the top of the pipe, the more holes I drilled.  It’s just enough to let the gutter flood to the right depth and slowly drain when the pump shuts off.

I’ve got the pipe for the new gutter ready to cut and mount but I’ll wait until the new aquarium is in so I know where to place my drain hole.  The new aquarium is 18″ longer so I have some good options.  I won’t be able to use a hard plastic threaded bulkhead because of the curve of the pipe but I have some Uniseal bulkhead fittings.  If I don’t have the right size I’ll order some more.

To keep the fish in the aquarium happy and healthy, I’m doing the water changes via buckets.  I siphon 5 gallons of water out of the 25 gallon wall receptacle and I siphon 5 gallons of water out of the aquarium.  Then I dump the aquarium water into the plant wall receptacle and the plant wall water into the aquarium.  It doesn’t take long, isn’t messy and isn’t very tedious so I’ll continue to do that twice a week until Terry gets the tanks swapped and I can move my plant wall back in.  We’ve got lots of baby fish right now and the catfish has just laid eggs again so I don’t know how he’s going to manage the swap without disturbing everyone.

Fish and nacent water lilly pads.

We have water lilly pads surfacing.  That must mean it’s spring . . . or something like it.

Updated overflow

I updated the overflow drain on the larger bog filter tank.  I’m still using electrical conduit elbow, but it’s 1½”, not 1″.  The outlet pipe is also resized for an 1½” tee-less connector.  I enlarged the hole in the piece of perforated drain which keeps the roots from plugging the conduit.

I’ve been finding more uses for inner tube.  This plumbing change includes a piece of bicycle inner tube for connecting the two pieces of pipe together.

The only thing I wish I’d done before assembly was to paint the conduit black, but once the water hyacinth is added to the tank the leaves will hide the gray.

Willows in pea gravel filled pots

I couldn’t leave the corkscrew willows in the upper biofilter tank.  The hydroton grow medium is not heavy enough to keep the willows upright and in the tank when the wind blew.  I knew putting them there was a temporary solution.  Yesterday I implemented a more permanent fix.  The willows are only in the water for this summer.

The half-gallon pots have recycled window screen in the bottom to keep the gravel from migrating out the drain holes.  The willow trunks are held in place against the side of the tank frame by truck inner tube pieces and staples.  The pots are held up against the side of the tank by cord hangers over hex head screws.  Everything can be easily removed when it comes time to plant the willows out after they go dormant this fall.

Glory and litter

Now that all the other plants have been moved out for the summer, I can get a good picture of the gutter begonia in all its glory and litter.  This is the dichotomy of prolifically flowering plants indoors.  The litter is non-stop but so is the beauty.  Click the image for the full impact.

Two stalks showing and many more in the works. Another plant showing a blossom stalk

The Cape Primrose has started it’s continuously blossoming cycle.  After the initial single blossom stalk, each new leaf will produce at least two stalks with two blossoms per stalk all the way through the summer.  Unlike begonias whose blooming period comes and goes, the Cape Primrose will just keep producing gorgeous blossoms.

The plant showing the single blossom is one of two or three.  If you click on the second image you will see a new stalk starting on another plant.  If you look closely you can see the base of the blossom stalk comes out of the base of the leaf.

The wall has gloxinia in it as well.  I don’t know if or when it will bloom.  The fun is in watching to see what happens.

Corkscrew willow in upper filter. Terry's antique toy trucks look great on the shop deck.

I had a lovely visit with my brother Dan and his wife Vala yesterday.  They live far enough away that I don’t get to see them often.  I was gifted with some corkscrew willow cuttings which I’ve stuck in the upper bog filter until I can get them rooted and ready to plant.

Wintered over and new plants out in the bog filters 3 gallon buckets ganged for flooding the grow beds Missing end cap allows the near bed to flood more.

It’s still too cold for starting seedlings outside.  The water in the tanks has finally reached 55° which means we can start feeding the fish, but that’s still a bit too cold for plants to grow vigorously.  Within the next two weeks that should all change.

I put the plants I’d wintered over in the laundry room out into the bog filter tanks.  I also stopped at JMH Gardens and picked up some penny royal, fairy moss and some kind of pond bean.  I can’t remember what Jill called it.  I’ll ask when I go back in a couple weeks for the water hyacinths.  I’m pretty sure “bean” is right, but given how I’d managed to mangle all the other things I purchased (fairy frost is a fabric not a plant), I’m feeling a bit less confident at the moment.

Instead of rock in the upper (smaller) bog filter I’ve added hydroton this year.  The lighter medium will facilitate the take-down of the filter in winter.

The grow bed plumbing is finished with the exception of one 1½” end cap.  Three 3-gallon buckets are ganged together using tee-less connectors and 1½” pipe.  Terry painted the buckets black which will facilitate warming the water over the next few weeks.

Once I’ve got the new end cap drilled with holes and installed the flood depth can be fine tuned.  I’ll plant the beds with seedlings the first of June if the water’s warmed enough.

Upper tank with hydroton

It’s still too cold to put out any of the biofilter plants I’ve tried to winter over but it is time to get the tanks in and circulating.  This upper tank is foam.  I got it at a year end sale two years ago for $10, a great buy.

Last year I used a tee-less fitting and a piece of rubber hose for the upper tank outlet.  All last summer I had issues with the upper tank overflowing due to a too small outlet with penny royal root blocking the flow.  I’m hoping I’ve solved some of that with this year’s setup.

I pulled the tee-less connector and inserted a tapering vacuum cleaner wand extension pipe into the hole.  After determining I would get a good seal, I pulled it out, trimmed it accordingly and reinserted it into the hole.  No sealant was required to give a good water tight fit.

This change allows better outlet flow and the mean level inside the tank is lower decreasing the chance of overflow.

What you can’t see (I’ll drop the water level and get a snapshot before I put the plants in) is the 3″ PVC pipe that keeps the hydroton out of the outlet and inside the tank.  The pipe is one foot long with a 45° angled end.  This angle fits over the outlet and is fastened to the tank with a 2½” screw.  The other end of the pipe is a straight cut which is covered with a piece of 30% sun shade cloth.  The length of the pipe has saw kerfs to increase the ability of water to enter the pipe.

Patrick's private wall - aquarium is under the floor (glass) and is 6x8 meters.

Here’s a great thing to share with you, a video of  Patrick Blanc giving a presentation on vertical gardens at the California Academy of Science.  The video is an hour and a half long and is broken into parts.  I didn’t have any trouble with buffering, so give it a try.  He talks about all his walls, what was good, what was bad and includes maintenance, inspiration, plants he used, insect control, maintenance . . . it’s well worth watching at least once if not more.

Blossoms everywhere.

I’m going to miss this plant when it goes into LouAnn’s wall.   It’s so robust and beautiful.

Half-buried tank, two grow bed trays. back side of the grow bed. Note flush bottle. When the water reaches a set level in the bucket above, it then overflows into the tubing feeding the coke bottle. When sufficient weight is reached, the bottle pulls on the cord and flushes the valve in the bucket. A small hole in the cap of the bottle allows the water to drain out and the cycle repeats.

This is my new setup, sans the second bucket.  I am waiting on tee-less connectors to add the second bucket to the dump tank (existing bucket).  I’ll use a short piece of 1½” plastic pipe near the bottom of the buckets to connect them.  The two buckets, connected together, will give me the volume I need to fill both beds in a single dump.

Here’s the list of parts.

• 2 five gallon buckets – mine used to contain pickles and were obtained from a local deli.
• 1 pump
• black tubing running from the pump to the bucket (visible in the top picture as the black loop to the right of the bucket and in the bottom picture).
• 100 gallon Rubbermaid stock tank (buried to first step in the tank side).
• 2 mortar mixing trays (the 8″ deep ones).
• miscellaneous scrap lumber – none of this lumber was purchased new.  I’ve got 4×4 for the four legs (mix of pressure treated and cedar – it’s what I had), 2×6 for the between post supports and 2×4 for the top plate on which the tray rims rest.  The bucket rests on a notched 3×4 and a notched 2×4 held up by 2×8 scraps screwed to the tray frame.
• a handful of 3″ decking screws
• 1 toilet flush valve.
• 1 16 oz plastic coke bottle (flush valve counter-weight).
• black tubing to feed flush valve counter-weight bottle (visible in the second picture – connects to a piece of aluminum tubing which inserts through the bottom of the coke bottle.
• miscellaneous hardware including a collection of stainless nuts and washers to act as the flush valve weight (offsets the weight of the plastic bottle so the flush valve flap closes completely).
• Plumbing parts – some 2″, some 1½”.
• Tee-less connectors to gang the buckets together.  I never order enough tee-less connectors.  They are the first connector I reach for when I have to fasten pipe to pipe or insert pipe into something.  I could have replaced the 2″ tee with a tee-less connector for less than a quarter of the price of purchasing a 2″ tee.

It took me an afternoon to take apart the old single-bed stand (I needed to reuse the legs and some of the shorter lumber) and another afternoon to construct the new two-bed stand.  You cannot see it from the picture, but there is a 2×6 that supports the center of the beds underneath going from left to right.

It took another afternoon to get the new bucket and flush assembly put together and get the tray flood plumbing set up.

I still need another 100 liters of hydroton.  It should only take another 50 liters (1 bag) of hydroton to fill the beds, but I want to increase the size of the gutter for my plant wall so want some extra to ensure I have enough.  Until I get the additional hydroton, I’ll let the beds cycle and build the nitrite/nitrate eating bacteria colony.

The new and updated dump bucket The roller assembly gizmo hanging on the side of the bucket. Note the notch in the bucket collar to accommodate the gizmo. The outboard end of the gizmo assembly. Note the notch in the lid to allow the lid to (mostly) set down on the bucket. The back side. Note the notch in the bucket collar. Stainless long necked bolt.

Yesterday was a  beautiful day, mild, sunny and quiet.  Wadly was off visiting family and I had the peace to putter to my heart’s content.

I managed to get the dump bucket for my grow bed rebuilt.  This time I added a genius gizmo for the flush counter-weight assembly.  This crafty  gizmo was the happy confluence of circumstance and available parts and it all started with the proximity of the flush valve to the edge of the bucket.

Because my 5 gallon buckets have a lot of ridges and raised lettering at the center I mounted the flush assembly against the side of the bucket.  This gave me a smoother flatter surface for sealing the toilet flush valve to the bucket and, by mounting the toilet fill assembly next to the side of the bucket, I was able to reduce the distance between the rollers that lift the toilet flush flap and support the flush valve counter-weight.  I saw the lock assembly for a sliding window sitting on the bench ready to be taken out to the aluminum pile to recycle.   That started the mental wheels turning and I was able to scrounge the remaining parts to pull this gizmo together.

The new roller carrier is small, requiring one small notch in the bucket collar for installation and support.

The rollers are from the bottom of a sliding glass door.

The bolts holding the rollers are stainless.  I have no idea where they came from.  Whenever we disassemble something for recycling, we take any potentially interesting small hardware and stick it in one of our multiple cabinets with plastic drawers.  We had this particular bolt type in two lengths.  The shorter was twice the length I needed but they do a perfect job.  The additional bolt sticking out is more of a design statement than a flaw.

The holes in the center of the rollers was just a bit smaller than the circumference of the bolt which allowed the bolt to be pressed into the roller assembly.  A bit of judicious encouragement from my rubber mallet did the trick and the rollers are now pressed onto the bolts.

The holes in the aluminum slider window lock handle were just slightly smaller than the threads on the bolts.  Because the piece to receive threads was aluminum and the bolts were stainless,I was able to force screw the bolts into the holes to create the necessary threads in the aluminum carrier.  You see what I mean about a confluence of circumstance?  The bolts were the right size to press into the rollers and the holes were the right size to accept threading from the bolts.  Kismet.

Each bolt has a fiber or teflon washer and a stainless washer to ensure proper spacing for the roller.

The rollers aren’t stainless and aren’t designed to be out in the rain.  Terry painted them for me to help keep the rust at bay.  As to the bearings, an occasional squirt of WD-40 (water displacement 40th formula tested) keeps rust in check and the rollers turning smoothly.  the arrangement allows the cord to be lifted off the rollers and the roller assembly to be taken away from the tank/growbed assembly for maintenance.  At some point I’ll make a plastic cover for the roller assembly to keep the rollers drier.

If you’re wondering what I used to extend the overflow tube on the flush valve . . . it’s a vacuum cleaner hand wand extension pipe.  We’ve got a shelf under one of the benches that gets all the plastic pipe chunks we might need for a later project.  Wand extension pipe is just plastic pipe and the taper makes them perfect for fitting onto other pipe or into openings of not exactly the right size.
