I just got my chapter newsletter, it mentioned using an old dryer for a parts tumbler, disconnect heat source, fill the drum with foam rubber, so that a 5gal bucket with lid will fit in the center, line the bucket with scrap carpet, bolt a couple of angle irons inside the bucket to make the items tumble, fill with parts and your favorite medium, set the timer and go on to something else. The top can also double as workbench. What do you think of that Michael?
