Air compressor capacity determines blast nozzle size. I think the process works less well as the ratio of blast media particle diameter to nozzle diameter rises. Also, more air filters are needed.

Looks like blast with soda to remove paint. Blast rusty spots with crushed glass to remove rust.

William Powell AT List member and soda blastor <william.neff.powell at comcast.net>;-tractor.com>  I converted a small blaster to soda using eastwoods kit. Found that it worked great on oily parts, the soda bonded with the grease. I did not have great results with rust. It clogged a lot. Might have been a humid day?


Aaron Dickinson AT List Member with soda blasting knowledge<a_dickinson at att.net>; My brother-in-law’s father does soda blasting in Minnesota, I haven’t seen it or talked to him too much about it, but he runs an airport and his primary projects are airplanes (read a lot of aluminum). The soda does a great job of removing the paint without pitting the metal surface. Not sure how well it removes iron rust.

James AT List Member and advocate of upgradeable tractor vocational training <jamesgpeck at hotmail.com>; A sandblaster that feeds out the bottom converts to a soda blaster with this kit. It looks like you could easily duplicate it.

I am guessing that soda is more negatively affected by moisture than sand and that all soda would need to be removed after each blast session. Looks like you can blow the soda out with this set of valves.

Soda blasting apparently does not remove so much metal from smooth surfaces.
