I just talked with on old Navy buddy. There are some chambers made of stainless.

Hey Ga_Boy,
That would be great and I was already to place a bid until I saw the PR. Anybody got a pair of water wings for a F 350?
I've been looking at the government liquidations, but searching under tanks, found a few good Sherman's but would find it hard to get the wood down that little hatch.

I've come across some SS tanks in NJ but didn't know what they would weigh so haven't persuaded that avenue. They other thing would be cutting the end off and trying to fit a flange around a 6' opening. SS is some pretty tough stuff to cut. Also don't know the thickness of the wall.
Den, you got some really nice chambers on your site, but as you say rather pricey.
Guess I'll keep looking and searching. I'm sure something will turn up. Just getting a little anxious to get started.
I'm thinking of building a prototype to try out the concept we've discussed and the methods of control. I'm a little hesitant of putting 10,000. into something were not quite sure of. What do you guys think?

Shopteacher,

Ya don't have to stick the wood down the hatch of the tank.

That is what that long thing sticking out the fornt is for.

Shopteacher,

I almost for got.

If ya had enough sense to buy a chevy would wouldn't need water wings. On a chevy you push the secret button and springs come out the bottom and you jump across that little mud puddle.

Den.
I shut down the kiln charge of 4/4 RO today.The half that wasnt under water turned out great!It dried at 53 degress C with no stress and very little degrade.This is #2 comm. lumber so some degrade is going to happen.
Im shutting down the vac kilns in about 2 weeks and taking a much needed break.I guess in 3 months they want to start the kilns back up and dry lumber.I may be back I dont know.
The lumber that was under water is still at 60%MC.We are going to send it to the DH kilns to get it dry.
To the folks who want to build a vac kiln.
A few years ago I helped a guy build a very small vac kiln.We used a home propane tank for the chamber.They are built for pressure.We could only dry a few hundred feet at a time but it worked well.I have to add that we used heating plates.I had a few at the shop that were scrap and we cut them down to fit in the "propane" kiln.
Maybe a propane tank would work for a small vac kiln?
Mike.

Finally, the kids got a bunch of pictures of my R&D kiln at our website.

You can see here how some of your heating and vacuum components might look.

Hey Den,
Just went through your revised web site and thought it's looking pretty good. Liked all the kiln pictures, except makes me want one more than I did before looking.
Couldn't find the picture of the one for $99.99 though.

How many of those heating plates does it take to fill the smallest kiln with 4/4 wood?
Do you take S&H Green Stamps?

Den Socling · « **Reply #148 on:** March 17, 2004, 05:19:42 am »

$99.99? You must mean the 300 easy payments of $99.99.

For 4/4, I'd put two layers of wood down and then one plate on top. You would need 8 plates.

There's not too many Green Stamp stores around. I'll have to pass.

All,

Where I work they are tossing a AB SLC500 PLC system. It has a HHT, CPU, Input, output modules. If any of you want it, I can grab it now before the scavangers get a chance at it.

I have no Idea if it works.

You pay for actual ground shipping.

First to IM me gets it.

Jason,

You got any idea if it is any good at all?

I'm in West Michigan, near Kalamazoo. What would it cost from where you are at?

If you can get me a weight, I can check it out. I am interested if it is fairly good shape.

It powers up but the FLT light is on. Could be as simple as clearing the memory or it could be the cmos battery is dead.

I guess it weighs about 10 lbs in all.

Jason, find a nice 5' X 12' SS tank and try that offer again.

Fault code 0056h according to the HHT under diag menu.

How about round milk bulk tanks. They are SS and are dished on the ends. You would have to cut the outside shell off and strip the cooling guts out of it. Then shore up the shell with stainless angle iron around the outside. Dunno hou thick they are though

You may end up with SS shrinkwrapped lumber

These can be had for a few hundred bux at farm auctions.

The perfect size Vacuum Kiln Chamber drove past the house on Sat. It was on the back of a 2 ton truck, and was haulin PROPANE.

Y'all gotta start hittin them truck salvage yards. There's GOTTA be one available, somewhere.

I could convert the one end to seal in a couple of days. The rest would be up to Den

Fla.-Deadheader.
So whata think?Will one of those ole propane thanks work for a vac chamber?
I have been asking a lot of questions about then lately.
My only concern so far is crossion from inside the chamber while drying Red Oak.
From the sounds of things they can take a lot of pressure.

The BIG ones are about ¼" thick. I do know that to make liquified Propane you have to compress it to 250 pounds pressure and that keeps it liquified, I think. When you release the LP, it turns into a gas with pressure behind it.

There is NO WAY a vacuum would collapse a big propane tank, like folks have in their yards.

In Ar. we used them to make rollers for mashin the rocks back into the wet ground in the springtime. I have cut open probably 8-10. We used them for furnaces, also.
