Black Beauty Blasting Media

Hey all im undertaking a new project, Chevy Kodiak C4500 cab chassis truck the frame is heavily rusted from salt and winter corrosion, i have a east wood portable sand blaster. first question is how big of a air compressor do i need for sustained use? second is i had it set up for soda blasting and that didnt work always clogged up. today i bought 2 100lb bags of black beauty medium grit. but it seems to clog either in the manifold or in the tip i cant be sure but when it does work it works great im new to this sort of thing any advice would be wonderful, if anyone is local and knows what their doing feel free to drop in

You probably need their finer grit to not clog. I believe the medium is 30/60 I use the 40/80. Startblast by dupont works better but I can't get that anywhere without paying to much for shipping. But for heavier rusted frames the 40/80 might even take to long.

in the couple blasts i got out of it it took the rust and all the heavy stuff right off and shows shiny steel but the compressor i have is to small its uses the air up after like 2 secs of blasting

You might call Eastwood and ask them for some advice, 1-800-343-9353

If that's the case then I would start by getting your air supply up to par.

haha ya know what out of all the pondering iv been doing about this i honestly didnt even think about calling them!

we do this type of stuff at work and you definitely need a industrial compressor and blaster. I would think you could get it done somewhere for about $300.

you could rent a pull type compressor the ones that runs a jack hummer.

I was thinking about a ingersol 80 gal upright compressor bc i would like to start painting but i know about 0 when it mes to them so for blasting and painting whAt kinda specs do i need to know gal cfm and such for sustained use?

ok so i went to a rental place today and rented a tow behind air compressor 185CFM the kind you see on construction sites running the jack hammers i also got a 300lb blaster, i only had 200lbs of black beauty and it went and far as it could , OMG the frame is shining already tomorrow i know where there is a pallet of blasting media im gonna go get cant wait to have it done thanks for the input guys

Being the cheap SOB I am, I always find a way to recycle as much as possible. Mainly by trying to blast in a partially closed environment, sweeping up and screening the grit. You'd be surprised how far it will go...

i had to blast out doors, the truck is sitting up on the flat bed trailer, i put a canvas under it then tied it up to make a kinda channel for all the material to pass through, the 200 lbs i got about 3 uses out of before it turned to powder, went the next morning bout 500 lbs more only used 400 recycled all tht about 3 times till the job was done so i saved it all in a big metal trash can, painted the frame today turned out amazing cant wait to start ordering parts
