Has anyone documented a home brew flow through system for small tumblers? I did a few searches but did not find one. I'm starting to deburr enough parts that it's becoming a pain to constantly change the soap/water.
I just finished doing this (last night) for my small tumbler, although I'm still experimenting with it. I used a spare 5gal pail I had, an old fish tank pump and some tubing/fittings from home depot.
In the top of the bowl I threaded in a 1/4 npt barb with a cap on the end. I drilled a small hole in the cap to meter the water flow. In the bottom I inserted 2 1/2 pip caps (could have gone npt but these had a lower profile allowing for better drainage) that I had drilled 5 holes in them for drainage. Sealed around them with some random epoxy I had (sort of like jbweld). ran a line from the pump to the top, and a lines from each drain back into the bucket.
So far the flow through system is working well but I had a drain line fall off last night (should have used hose clamps) so half way through the run it ran out of water resulting in grey sludge that stains the parts
Anyone know a good way to remove the staining? I'm thinking of trying a dip in lye.
