bead blasting question

[anthonyinva]

I just tried it for the second time and not liking the results yet. First time too much air pressure (90psi) created a rough finish, this was done with a pressure pot blaster. Second time I used a syphen gun with air adjusted down to 30psi(I'm guessing), with much better results but still rough compared to other jobs I have seen and felt. I am going to build a blasting cabinet to do this in next to save on the wasted beads. Any advice or pointer would help.

thanks,
anthony

What are you using for media ?
I run at 90#'s with glass beads in a cabinet and get a pretty nice finish..

If your looking for that real soft bead blast look try rubbing it down with some oil and fine steel wool after your bead blast. I know it sounds kinda crazy but give it a try I think you will like what you get.

There are different grades of glass beads. Check out Graingers and see what they recommend for a nice satin finish without the roughness. I would suspect that they might also be able to give you air pressures to use as well.

320 grit beads will produce a nice finish

Just stay away from harbour freight as it will have beeds mixed in that are way to big and it cuts like a dull butter knife.
