I made one and am quite pleased. I got a used drill press for $40 that looked like new, the small 8" made in china press. I spent $5 on SS bowl, $5 on rubber trim for bowl edge, Oh I had to buy a 1/2" Fine thread trap and bolt and washers, maybe $10 total and I have lots of 5 gallon buckets and used one for my spin/spray catcher.

I'll post some pics and videos if anyone wants to see mine all though it looks like the others, except my spray guard.
