Been using this fiberglass tub for many years as a soak it parts cleaner, it sat on the floor and the ultrasonic cleaner sat on top of it. When I wanted to soak and/or scrub something in the tub I’d have to move the ultrasonic out of the way and kneel on the floor at the tub , seen enough of that. Had various parts and pieces in inventory so I thought I’d try to improve its use.
I’ve been working at this for a bit , some trial and error and some upgrades. I found out after I pneumatic-ized it the lid needed a gasket as I was losing air and product , had some excellent 3M self adhesive weather stripping so I fitted it up , problem solved. Next it needed to hinge and secure the lid tightly to the tub , some hinges bent to fit and rubber latches did the trick. When I hit it with air it would warp the lid , pushing it up in the center, I figured the stress ( it will hold 40 psi) would eventually break the fiberglass down, I had a piece of 18 gauge 304 SS , some autobody two part epoxy panel adhesive, problem solved.
I wanted to filter the crud out of the solution so I added a chemical transfer pump and chemical rated strainer and filter housing , pleased with the results. Plumbed it up for air , and a vent , added a shelf to the bottom to keep parts out of the sludge build up.
Last made a rack to hold it and the ultrasonic cleaner. Added a light.
It holds 12 gallons. The air agitating the solution makes a good scrubber. Pleased with results.
