make small hot tank

[curtis reed]

A good safe biodegradable cleaner is Oakite brand cleaners. We had a hot tank with their cleaner years ago. When we needed to change to fresh chemical we would mix it with soda ash to render it inert. Here is a list I found online of what they offer.

The oakite products that I have used were all alkaline. I don't think soda ash, also an alkaline, would neutralize them. All I have ever used is the old powder. Probably have something new I'm not aware of.

Just for the home shop and the inconvenience of dragging everything but the 50 year old seriously gooood up stuff to the machine shop --- I cut a house heating oil drum in two and shortened the legs , bolted two pieces of angle iron to the back, cut a piece of 3/4 " plywood for a cover and hinged it to the angle iron. Placed an old fireplace grate in the bottom , drilled a bunch of holes in a piece of 3/8 brake line with a valve and laid it under the grate for aeration . welded a bung in each end and screwed in two heating elements and the thermostat set at 180 from an old hot water heater. Used nothing but ( Tide ) . Took a little longer but smelled great. ------ Put it outside on the concrete pad and used the engine hoist for blocks. As they say " it worked for me"

Lye will keep the rust away on a steel tank.
Two furniture repair guys, different size tanks. One, he's still around, has a 4 X 8 X 18" steel tank, open top, 35 years and no rust. The other had a 4 X 6 X 5 with a lid, not sure where that went. I like the fuel oil tank previously mention, I'm looking for one now.
