[AT] I hate sandblasting!--but see this.....

[Louis]

I have used crushed glass in my blasting cabinet.  They leave a rough
profile compared to glass beads.  The crushed glass breaks down faster
than glass bead and becomes ineffective.  I was sold the crushed glass
on the claim that it is less expensive.  Well, maybe initially, but
there is no real economy, when it has to be replaced sooner than glass
beads.  I like beads for cleaning carbs and other small parts.

Did a little "research" after the string on blasting with sand and
walnut 
shells.  I'm going to try water/media blasting using my pressure 
washer.  You should take a look at the ProJet sand blaster kit from 
<http://www.projetpressure washers.com> (that I just ordered), but 
especially some information I found on using crushed glass instead of
glass 
beads or silica sand for outdoor or cabinet blasting at 
<http://www.trivitro.com/tech_msds.html>.  Read the media blasting 
section!   And if you want more detail the guys at both of the above 
businesses in Kent, WA are most helpful.  I'll probably have to wait
until 
Spring to give the water blasting a trial run on an old 9N tractor with
a 
gazillion layers of old paint.....and will let you know how it does 
then.     You can buy a less expensive sandblast kit from Northern Tool
but 
the Pro Jet model has some significant advantages in my book.    John W.
