Larry:
Funny you should post this...
Eugene and I have been corresponding. He sent me his idea for a parts cleaner, one that he has actually built. I have the pics and the narrative and I am putting the presentation together. This is not a small table top unit... it is for slightly larger parts such as the rear end of a Cub

It should be up on the server in the next week or two.. I hope
Based on what we have been discussing, I am planning to build me one over the winter, I shall document it of course.
As usual, the more ideas the merrier. So.... bring it on.
However, I do agree with Big Dog on this. For a small parts cleaner, you are probably farther ahead to buy one from Northern Tool or Princess Auto, especially when they are on sale. The kids got me my small one for my birthday.. was $80.00 Cdn about $65.00 or $70.00 US at that time.. back when we was getting around $0.72US for a loonie.
But, now ifn you are gonna use slightly less than new parts, that is a different kettle of fish

Sometimes what can be somewhat described as cheap is really frugality or better yet, the 3 tenents of good environmental science -- RRR -- Reuse, Recycle,Reduce... that is where the fun is...
