Sand Blasting

So I'm getting ready to blast some parts of surface rust. Have some original seats I'd like to do this weekend. I've read walnut shells or glass beads are good for this kind of stuff. Love to hear any more advice from those of you who have tackled it!!!

Thanks!!

 

I was wondering that same thing? Walnut she's OK? I was given 3 25 lb boxes. I just bought a small hand held. It runs at 120 psi.

 

It ony holds 25 lbs of aggregate

 

Yes sir really fine. I think they're close to glass beads. My brother had mentioned them to me in casual conversation. But you're right... Only one way to find out.... Was surprised I couldn't find a stream on blasting.

 

Will post some pics tomorrow night or Sunday with info. Thx for your advice

 

My understanding of walnut was that it was soft, and wasn't good for rust, but good for paint. I may be wrong....

 

OK thx for the update. May need to change out then

 

Opinions guys....My first foray into blasting. Used glass beads

 

Now you need to protect the exposed metal immediately.

 

Yes sir, set for this am!!!

 

Seat frames would work best with sugar-fine sand. Seat frames won't warp and distort like sheet metal. I use glass beads and crushed glass for more delicate parts as glass isn't as aggressive as sand, garnet, or black blast. Walnut shells are very soft and clean without really disturbing the surface. I use walnut shells for cleaning carburetors where it doesn't remove the green/yellow coating, or for transmission gears.
If you end up doing sheet metal, keep pressures low so you don't warp the metal. Many tubs, fenders, and hoods have been ruined by sandblasting.

Thanks Donny. I left you a message in another stream with a couple of questions.
