[Mgs] sandblasting

[Paul Osborne]

David,  give a look at tptools.com.   they are great when it comes to 
blasting.  I have one of their homemade cabinets and have been using 
their "first choice" abrasive.  $30 for 50lbs   great stuff.  I power 
it from my 5hp compressor with a 50 gal tank, that to is a home built 
unit.  any ways ck them out they have a lot of useful infomation 
about blasting , types of abrasive, parts etc.
As you use your to clean parts remember to wash the parts before you 
stat to paint.  The abrasive will pit the surface some but after a 
few coats of primer, lite sand  in between, and the same with paint 
coat ,  you should be very happy with the results.
