Mike:
Although I haven't put it together yet, I purchased a 12" diameter schedule 40 pvc conector pipe. About a foot in height.
Obtained (2) 3/4s inch thick lexan from a local Plastics maker and distributor,.
I know it will work do to the fact that I originally obtained the instructions of its construction from a prior member of another group.
Also purchased and made my own "0" rings from a smooth rubber mat material that Lowes and Home Depot sell by the foot for the bottom shower stalls
Unfortunatley the original instruction and source are their temporarily locked in my down computer so I can't track or currently obtain the source where I first found them on line.
Alumilite sells a similar contraption for about $75.00 also a schedule 40 pvc material,.
Just remember too much pressure and you'll be in trouble this is a headache you do not want. Heed the warnings.

Re: Make your Own vac chamber
Posted by: "upliftedape" upliftedape@yahoo.com upliftedape

This is maybe the cheapest and effective way to do it. I have built 5
from scratch with 5 completely different setups and I like my latest
the best. I would recommend going to craigs list or a food equipment
seller and picking up a cheap used stainless steel prep table. Drill
a hole about 3/8" or so where you want your "jar" degassing are to be.
Mine is on the right side of the table mid way between front and
back. Next you need to buy a floor flange from home depot/lowes.
This item is a steel flange that has 3 or 4 screw holes on ears and
pipe threads in the middle. They are about $3.00. You center the
flange over the hole you drilled then take a marker and mark off where
the screw holes meet the table and then drill those. Find appropriate
size bolts and nuts as you will be bolting this to the table surface.
Also you will need a tube of adhesive/high quality silicone sealant.
The thing about this is bolting the flange to the under side of the
table with a good amount of sealant on it and ratcheting it up tight
and flush. You then need some heavey duty hose, hose clamps, a short
threaded pipe on both ends and a barbed push on hose adapter that fits
onto the piece of pipe. The pipe goes into the flange. The barbed
hose adapter goes on the end of that, you add your tubing which goes
to a release mechanism and then to your pump. The advantage with my
setup is it it very easy to clean and you can scale your vacuum
projects. I will gladly provide photos just email me at
upliftedape@yahoo.com
For the bell jar I have two methods I just to make one, but the
current method I like the most. I bought some vacuum gasket tape,
which is amazingly cheap, and I bought a 2 gallon glass cookie jar
from walmart for $12.00. This is maybe the thickest glass item you
will have seen for some time. I have an amazing vacuum pump and I
have used these jars literally 1000's of times with not the slightest
problem so don't worry about the whole things about needing a rated
bell jar. You simply take your vacuum gasket tape peel back the
adhesive protector and run a bead around the the inside lip of the
jar. This will give you an amazingly well sealing very large totally
transparent degassing chamber that can easily handle degassing about a
kilo of mixed material at a time.
pictures of bell jar and chamber can be solicited from me for free at.
upliftedape@yahoo.com
Minus the pump this whole setup set me back a while $170 and that was
$150 for the large 72" X 40" X 36" stainless table. I have a high end
scientific 23 CFM vacuum pump that weighs close to 300lbs so I don't
recommend that for beginners, but if you want almost any quantity of
material degassed in less than 45 seconds there is NOTHING better.

Ok, now that's darn cool. would they possibly have one for sale for us not able to build something like that but have a need for one? i've got some cash burning a hole in my pocket and one of those would fit my needs very nicely :-)

I thought it was neat and bookmarked the page as a project
I might want to do one day.
But if a few other people are interested I can prolly get on the
case and do a bunch of them at the same time.
FWIW, I consider myself an experienced builder and have
a reasonably complete shop in my basement.
Some would call me a home shop machinist. Others might
use somewhat harsher language! :-)oo
My sig file has more.
Haven't really gone over the project yet, but a few things
come to mind.
- Not sure about using wood. Aluminum might be a bit more
sturdy. But a hardwood could work.
- Somebody did a nice job but I don't like the way some of
the things were done. But probably done this way so that
a builder wouldn't need many tools. I would want to make
some changes to improve the reliability.
- Where I come from those gears are called bevel gears. But
here I go quibbling again. :-)
- Depending on what you buy or can scrounge, I'd say there's
about 50 to 100 $$ in materials.
- Not too sure about my time but I would like to get a better fix
on what parts we would decide on and exactly what needs to
be done. That said though, I doubt that this contraption
would be worth more than a few hundred $$.
Any interest?

if it worked and the parts were replaced easily as they wear out, yeah i'd
buy one or two. i don't think 200 bucks is unreasonable for something like
that. i've shelled out more than my fare share on stuff that doesn't work, not
knowing that at the time. the wife (or husband) might object to resin covered
walls. (i don't have that problem, i don't have a wife.) i see the idea
behind it and might give it a whirl (get that?), yet a pre-made version would be
easier. i really don't have a couple thousand bucks to lay down on the real
thing.
randall
ps: does anyone have an effective way to get resin off walls? just wondering.

A spincaster doesn't look that difficult to make. You can power it with
a small electric motor or hook it up to your bike.
