Well, here is a status report... I've spent all this time figuring out
how to build this. I have since bought an air compressor, 1/8" brass
tubing, compression fittings, micro drill bits, a tubing bender, fine
mesh screen, and custom-cut Lucite squares of the appropriate size. I
also acquired wet/dry emery paper from 220 to 2000 grit. I have all the
pieces now. I am going to make a multi-chamber unit, with 6 mills going
at once, each one with a different grit size. This is probably
overkill, but I figured if I am going to make one of these, I might as
well make it substantial.
Now I need to get ready for an apartment inspection, finish an asbestos
talk for May, and if I survive that, vacation at the end of May. So I'm
thinking it will not be until June when I get this finished.
More later,
Don
