Speedy Sprayer Pressure Pot

[PenMan1]

I was able to get a "Speedy Sprayer" pressure pot made by the W.R. Brown Company in Chicago.

I have been unable to find hardly any information on the pot other than it appears to have been made in the 1960s. It appears to have a "cast" top (very heavy) with a flange that wing nuts attach trrough. It has a rating of 50 PSI and the seals are in good shape.

The bottom part of the pot is very heavy aluminum and the sides and bottom show no "rounding" or bowing.

Before I start applying pressure to the pot, I wanted to see if anyone here knows about this pot.

Thanks for any help.

I don't know this pot. Take it to a shop that builds pressure vessels. Have them test to 50-60 psi. They have the equipment and the knowledge to do it right. Be safe.

I would put it under water like in a pool and pressure test it...keeps any bad stuff to a minimum.

Thanks guys! Both good suggestions.

Glenn, In "redneck speak" your suggestion means put the pot in a 55 gallon drum filled with water and "hold my beer and watch this".

This IS the route I will likely take. Regardless of the outcome, it should be fun to watch!

Andy,

Does it look anything like this one? If so, this is a DeVilbiss pot that was made for private label for different companies. I have 2 of them that I don't use. One is labeled as a DeVilbiss and the other is a Craftsman. Both are a helluva lot better than an HF pot and I used the one in the pic below successfully for the first year or so of casting.

Curtis:
I'll try to take some pictures. Mine looks similar but "more hefty" My lid looks much heavier. The lid alone weighs about 10-15 pounds. The bolts attach a little differently, but similar. The pot looks to be about the same age as yours.

I have sent you a PM. I am going to pressurize it, maybe under water to about 45 psi and see what happens. additionally, I have quite a bit of air hose. I can take the pot to a safe place and regulate the pressure from the compressor and see what happens.

My last experience with the HF pot was not good. I don't to make the same "almost deadly" mistake again!
