sand blasting
 

I'm currently sand blasting the frame of my ls6 with an abrasive called black magnum.It seems to me that it goes through the blaster rather quickly.I've used close to 20 50lb bags already,is this a normal amount? My blaster is a 40lb pressurized unit that works great,but I'm always refilling it.

HI IT DEPENDS A LOT ON AIR PRESURE AND HOW RUSTY THE FRAME IS https://www.yenko.net/ubbthreads/images/graemlins/no.gif

Also depends on nozzle size...

And all this time I thought size didn't matter...

I had the frame on my 69 done with Black Beauty. Same stuff. IT works GREAT.... anyway, the man had a 20 x 40 garage converted to do just sand blasting with this stuff. he must have had a ton of it on the floor... So, yeah it takes loads of this stuff. All it is, is coal slag. https://www.yenko.net/ubbthreads/imag...mlins/flag.gif

Coal slag? That doesn't sound like a fun day at work (or home for that matter). We use plastic media at my job but it's limited to parts that you can fit in the cabinet. My boss is looking into buying us a baking soda blaster which I had never heard of. He says the parts come out looking like new and prepping for paint is much better (cleaner/quicker). Marc

Baking soda blasters are great. Black beauty is not bad to work with, especially for the price. It does dull out pretty quick but the results are worth it.

In my area, sand is cheap and is the choice for blasting 'hard parts' such as frames, rear end housings, control arms, etc. I catch and recycle most of it.

One the other hand, I use Aluminum Oxide on thin, origianl sheet metal which is very easy to distort.

Bottom line is to use caution and common sense.
