[TheForge] Cleaning components

[Dan Brewer]

I visited a foundry that had something like you are describing.  It was a
14 inch pipe about 10 foot long one end was welded shut and the other had a
door that was bolted on.  It sat on a set of rollers with one being driven.
It rotated at about 100 rpm.  The interior of the tube hade been coated with
Rino Liner ( the stuff that gets applied to pickup beds) to help dampen the
noise that it made. They would load it up during the day with the parts to
be deburred and  then load in a bunch of common hardware (nut nad bolts and
washers and small bits of cutoff metal ) and turn it on just before leaving
the shop at night.  It was on a timer so it would run about 10 hours. It
made a lot of noise.  The next day they would empty out the parts.  You
might want to start with some ceramic material first in a soapy water bath.
The soap and water server to keep the media sharp and keep the stuff being
deburred in suspension.
