Re: aluminum polishing

BTW, don't glass bead the carbs as it'll be tough to get out the beads and
beading really screws up the finish. I tried it on a useless carb.

Actually I have good luck glass bead blasting carbs. Admitted there are 
things to watch out for but it can be done. Never sand blast aluminum as the 
pointy sand bits embed into the surface and cause no end of trouble. The 
round beads don't do that. I use a fairly fine bead and don't get too 
agressive with it. The inside of the domes get very light or no blasting and 
the pistons get none unless I can't get them clean any other way. One problem 
is that the aluminum sometimes gets staining down into the pores of the 
metal. If you blast enough to remove it you end up removing way too much 
material. If you use the bead blasting as a surface cleaning only it works 
well.
