Wet sanding with 400 grit, then 1000 grit before hitting it on the buffer.   Finished the black oxide treatment on the rear hardware, and I think it turned out pretty good.  

The first picture is after soaking in Evapo-Rust.  The second is after blasting.  The last pictures are after the black oxide treatment.  All the old hardware that I am using will get this same treatment.  Almost looks painted.

Now I can finish port matching the heads, and finish the accessory brackets.  U-joints and rod ends turned out pretty good after paint.  Still working on getting the aluminum rear end components polished and re-assembled.

Started soda blasting aluminum parts today.  Looks like everything should turn out pretty nice once I get it all polished.  Should be painting rod-ends, bearings, and u-joints tonight.  Tomorrow I will continue blasting and start cleaning drive yolks and caliper pucks.

Finished the tedious aluminum grinding over the weekend.  I still have a couple of drive-train pieces to grind, but they are not nearly as intricate.  Next step is to soda blast, wash, and polish.  Unfortunately when I got the blasting box out this weekend I noticed that the gloves had rotten away.  A new pair should be here in the next day or so.  Today I managed to get the old wheel studs out of the wheel bearings, and press the new ones in.  Turns out I had to ream every hole to get the proper press fit.  Just a little bit of paint and they are ready to assemble.
