Super Jet Engine Blasting

[trojoro]

I have a guy who can soda blast my cases and cylinder. My question is what should i do to prepare before sending them to him? Whats the best way to keep the machined parts from getting damaged?

Just degrease them well, and you can tape the surfaces but I don't think it's necessary with soda.

You can also tell him to avoid the mating surfaces.

I do all my blasting at a friends company that does monuments and headstones. They use a a adhesive backed rubber material for their stencils. I use scraps trimmed to the shape to cover surfaces I don't want blasted. I also use granite powder, it's a bit more abrasive than soda but makes easy work of it and leaves a beautiful finish for paint.

Do it to every motor I build, I even hit the gasket surfaces and water jackets. Using glass bead material

Okay I'm just going to worry about taping up the crank seals mating surface and make sure he uses a glass bead material
