sheerider11 Posted October 21, 2015 Report Share Posted October 21, 2015 Sealing surfaces I try to avoid. But as long as your not against the surfaces with the gun you should be okay. Just don't go crazy Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted October 21, 2015 Report Share Posted October 21, 2015 Stick them together, tape the clutch side off, tape the bearing openings on the stator side and the stator cover mating surface. Blast on... Give eagle one wheel etcher a try if you don't have access to a blaster. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted October 21, 2015 Report Share Posted October 21, 2015 Isn't soda blasting or walnut a better option for cases?I used a combination of walnut and sand in the blaster I was using. I went to harbor freight and picked up a few things. The sand did almost nothing. The walnut shells worked well. I will try glass bead and steel shot one day too Quote Link to comment Share on other sites More sharing options...

Dixie normus Posted October 22, 2015 Report Share Posted October 22, 2015 Put some old bolts//screws in all threaded holes. U don't want sand in those Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted October 22, 2015 Report Share Posted October 22, 2015 I use glass media and I hit everything , pull all bearings seals , after blasting I run tap through every hole, wash with hose, then I go inside to my wife's sink use hot water and dawn , scrub all mating surfaces and anything else you feel needs it. Blow it dry , ascetone mating surfaces with white terry cloth and you'll know rite away if it's clean enouph 1 Quote Link to comment Share on other sites More sharing options...

blowit Posted October 29, 2015 Report Share Posted October 29, 2015 Agree with above, I would select a less harsh media. Soda, Walnut, or dry ice. Sand will actually open up pores in the Aluminum and it will stain rather easy. Glass seals the pores but still is a little aggressive IMO. You may also consider clear coating the cases if you sand blast to seal them. 1 Quote Link to comment Share on other sites More sharing options...
