Case finish - Sodablast/Beadblast

[flat-happy]

wd 40

after you bead blast soak the cases with wd-40 and scrub with a brass or plastic scrub brush. the oil will lubricate the beads and make them easier to remove if they get imbedded from too much pressure. look at the cases with a magnifying glass under a bright light and you won't believe how much of the glass is imbedded in the surface. that material will eventually get into the bearings. after you wash your bike reapply a thin coat of wd-40 and the finish will stay new indefinitely. i just got a 59 panhead up and running again that i restored 30+ years ago and the cases and heads still were bright and new---stillman

i was thinking of boiling water after the bead blasting. then pouring the water into the dishwasher so it is hotter than the water heater puts out and putting the dishwasher on pots and pans that add extra heat also. Hoping that would open the pours and remove a lot of the bead blast residue.

Got to thinking about this and I don't see where the high pressure washer we have here in the shop wouldn't do an adequate job. Bob

[Glenn]

would the high pressure washer just push some of the glass beading in further ?

Further or all the way through. Oil holes are open on both ends ya know. I have had glass beaded cases used on rebuilt engines that showed no harmful results.

I meant further into the case itself not into the oil passages and would glyptal be able to seal that in

I doubt you have enough pressure on hand to embed glass beads into the aluminum.

Brian my pressure washer has far less power than my blasting cabinets. If anyone is really worried about this stuff just boil it in water for fiftheen miunites. The pours will open and job is done.

Vapor Blasting...?

I've seen this process advertised on eBay, does anyone have any input on it?

Yea, I've heard it called something else though. Never seen anything done that way in person that I'm aware of. I'd still scrub the hell outta my stuff, abrasives are abrasive and have no place inside a new assembly.
