Went to buy a sandblaster today but I didnt know which is better
Gravity feed or Siphon
Dont ask the salesman said there is no different :)

You want a pressurized blaster.
Like the one below. Thats a different brand than mine but same type of blaster. Mine is a US Sanblast brand. Have had it for about 12 years. still works great. Have rebuilt the end valve several times, and replaced the sand two ball valves and the lower nipple a few times. Sand is hard on them. Eats them away from the abrasion.

Siphon and gravity fed are only good for little surface spots, or aluminum rims, intakes etc.

i just bought a sandblaster like the one blazin posted only the 20 gal version.
havent really got the chance to really use it but i did a hood hinge the other night and it worked great.

I had a gravity feed one that you had to refill every 20 seconds PITA
I had a siphon feed one that would constantly clog
I have a blasting cabinet I use that will fit an intake manifold for bench stuff
Outside I setup a tarp, wear a snowmobile helmet, put on a zoot suit and use a pressurized blaster and find that works the best.

Ok went to sandblast the frame and went thru a 50lb bag of #8 Glass Bead and only got about 6 to 8 inches done am I doing something wrong or will it take a ton to do the frame ?
I bought some of these to see if they work any better (http://www.dewalt.com//ProductImages/PC_Graphics/PHOTOS/DEWALT/ACCESSORIES/LARGE/8/DW8306_1.jpg) its a flap disc ?? goes on the grinder.
Any other suggestions to cleaning up the frame ??

Typical frame takes me between 10 and 20 bags to clean it down good. There are adjustments on most blasters. On mine I keep the air valve wide open and the sand valve around 1/3 to 1/4 open.

I have used that same grinder wheel on my metal work. I strip paint/rust off of angle iron on my 14' trailer. I have welded a few things to customize it. The wheel works really, really great, however, they wear out pretty quickly, and you need quite a few of them. If you plan to use that on a frame, I'd get about 20 of them. I get mine from Northern Tools, they are reasonably inexpensive. I have a 4 1/2 inch dewalt grinder I use mine on.

I have the sandblaster that Herold showed - works GREAT but has to be set up so it doesn't blow through the sand. Air all the way open and sand valve cracked to about 1/3 or until I get good blast results.

This way will take years to finish :)
I just bought some wire brushes and two grinders to attach them to I will teach my wife what needs to be done so maybe I can paint half the frame this weekend :)
