I have one of the metal Harbor Freight type 20 gallon parts washers that I use mineral spirits in now. I would like to change over to water base. Some of the heated parts washers get pricey, $1500 plus, so I'm thinking about putting some type of heater on it like this http://www.hotubparts.com/hot-tub-parts-menu/hot-tub-heater-menu/screwplug-flow-thru/ . I thought maybe I could buy the parts at an eletical store and build it cheaper than that. One problem with the element is if you drop a part on it, it could damage it and short out. I'm thinking put the element in a metal tube or cover to protect it. I'm not sure if I can bore a hole through the side of the tub and mount the element without it leaking and then I have to figure out the thermostat. I'm also seeing some flow through heaters ($50), but that might mean another pump. Here's another unit http://www.oileater.com/PartsCleaner.html, but they probably get pricey- there 5gal unit is $285.
Any good "safe" ideas on how to go about this or forget it you'll fry yourself?
