[TheForge] soda blasting

Thu May 22 21:35:10 2003

Building a pressure vessel is serious buisness, I now because I do it, the
liability on manufactureing 1 pressure vessel that could explode and kill
and bystander is about 50 million dollars.  Buy a sand pot and modify it, a
large vibrator will work good enough for most purposes.  As someone else
said vibrators are not that hard to make.  Figure for ever pound your pot
weighs full you need 1 oz of weight at 3450 RPM.  a 1/4 or 1/2 HP motor is
plenty.  Follow the quidelines to mount it to the sand blaster and ur good
to go.
