Welp ... both my water recirculation system and my propane supply are in and working.

Here's a few photos to show how I set it up ...


As always, Photobucket loads pictures backwards, so click the right arrow or the "Previous" button.

Comments welcome!!

I hope you dont mind, but I have posted a possible alternative to the link to PhotoBucket. I don't know if it's my comp' or the site, but PhotoBucket seems really slow. I used the thumbnails along the bottom for the pics below; you can click on the pics to get full size image.

Laying out the parts for the water circulating manifold.

Laying out the on switch, speed control and pump for the water circulation system.

I don't always clean as I work ... **smile**

Soldering the connections. This harness got turned 180 degrees. The switch was upside down.

Testing the wiring and pump with a closed loop.....etc...etc...

I stopped there as it was taking me ages to get to each pic on PhotoBucket.

It makes for much easier browsing...just a thought :confused:

An amazing job btw...you make me want to move home; I live in a flat...no room.:(

I guess it beats my pond pump in a washing-up bowl full of ice water :o

It all looks very expensive...is it?

On the point of PB reversing the pics...could you not load them in reverse?

Ghislain ...

I'm far from expert on Photobucket, but I will look into better, easier postings. Sorry for the complication.

And thinks for your interest!

Just an FYI ... my total [cubical] work space at the moment is 6'x8'x3' ... in a small room at that. Wide angle photographs tend to exaggerate.

I can tell that sometime in the near future I'll have to find another space. Glass storage alone (generally over the desk opposite and in my living room) is becoming a problem. Something may happen in the basement, but heating would be a problem in Winter. It already is for my darkroom down there, although I have a separate furnace for that space. I'll just play it by ear. This space may be useful for some time.

As for costs ... let me run a rough tally. I'm curious myself, but not sure I really want to know --

Small (12VDC) Pump (Ebay) - $9.00
Blue Lighted Toggle Switch (Radio Shack) - $3.50
Nylon Angled Tubing Barbs (4@2.00 - Lowes) - $8.00
Vinyl Tubing (20' - Lowes) - $5.50
Gas Outlet (Ebay) - $14.00
Black Surgical Tubing (Ebay) - $10.00
20lb Propane Tank (Lowes) - $30.00
5' Propane Hose (Lowes) - $23.00
Propane Regulator/Valve - $15.00
(2) Brass Pipe Fittings - $12.00
Propane Tank Fill - $15.00

Total $145.00

Of course, that doesn't include the Soxhlet or burner. Everything else I had laying around. I was raised to retain/acquire things like brass fittings, knobs, electronic or electrical parts, nuts, bolts, screws ... things like that.

One has to be careful of "hoarding," but I can't tell you the number of times I've needed something at 2 in the morning on a holiday and found it in my shop.

Getting anxious to get to work, but contemplation/meditation and patience is as, if not more important than the work itself.

Very pretty setup you got there.

For those looking to do this on the cheap:

submersible 120v fountain pump from hardware store: $20
aquarium tubing from hardware store: $10
disposable cooler from dollar store: $2 (or a pot from the kitchen:$0)

If you're really, really cheap... you can get one of these for about $2 at a hardware store:

This way you get a hand workout at the same time, and you save electricity. All without porn! =O
