DIY Sandblaster

[solarman216]

Couldn't find any info/plate on it but online it says max air consumption is 700 litres per minute (7bar) which equals around 25cfm. According to Google :nenau

Yep much much bigger than you average home jobbie, Rick

Well it kind of worked, I could have made it work well if I had bought some brass fittings but when I went to my usual motor factors to buy a socket and rust treatment I saw one for 12 squids, no brainer really, I'll still put a vid up if u like banshee :thumb2.

Rick, my compressor only has a 24ltr tank but it's cfm rating is 9.5 at 8bar, which ain't too shabby, sandblaster I bought operates at various cfm max being 8 cfm so should work fine, I've seen compressor tanks for sale on ebay with no compressor so I may buy a bigger tank if I start using it more, if it works out economical compared to a new compressor that is.

You can reuse media if you sieve it & you don't use it to blast oily parts etc.
I have a pressure pot which holds around 2 bags of media it has a 6mm nozzle which requires 80 cfm + a bit extra for the air fed mask.
I have used calcium silicate to blast oak & a fine grade shot for blasting panels I have also used crushed glass which seems to be all the rage with blasters at the moment but I didn't find it flowed that well it also breaks on impact so isn't very aggressive or abrasive.

Kiln dried sand should not be used for blasting.

Yeh I plan on capturing what I can and reusing it, why would you not use kiln dried sand?, I have never done and blasting before, cheers :thumb2

Sand generally contains silica which could lead to silicosis.

First of all you are absolutely right all I am saying is fine grade shot is more effective so works out cheaper & as far as anyone knows doesn't affect your health.

What actually is "fine grade shot" and where do you get it? Rick

 

[Terrano Steve]

Key abrasives 01302 714517. Anglo scott abrasives 01942270729. Stacey processing ltd 01629 825188.

Last lot I bought from Anglo Scott but the other 2 are good companys.

Thanks for that, I will try one of those if only for the reason that if it is more efficient then I may be able to use less air as I struggle with the two compressors that I have, Rick
