I must've missed posting a couple of shots going in to the tranny (for what it's worth)...

Cover has a couple of scratches, should clean up nicely with first steps of polishing-

Image

Typical goo & grunt in the outside cover, just a tad bit of rust-

Image

Inner cover in similar shape, so far nothing amiss (I've seen much worse!)-

Image

Surprisingly little water/moisture-

I just got real good news; Jeandr has agreed to fabricate T6 aluminum engine & tranny mount plates! I'll send him the originals, with the pattern changes to accommodate Commando tranny adjusters on BOTH sides for nice even primary chain tightening.

Cool; HUGE thanx. Klink will be quite pleased!

Tank underside -

Image

Still trying to find a match to photos of the paint, caught a break when I cleaned off the gunk leftover from the tank pad-

Image

The guys are drilling, pulling and welding all the dents and dings in the headlight ear and sidecover. The tank has some Bondo repairs that will be removed and properly repaired (pix before the weekend of the bondo, then the stripped parts)

Atlas head (25319 casting) in good rebuildable condition -

Image

Image

No broken fins, no stripped threads. I'll pull the studs out of the old head.

All new valves are here and were delivered to the machine shop with the head, along with valve springs, keepers & collets from the old head. Just waiting on the new guides.

Powdercoater is shooting to have the frames done tomorrow and meet me half way (saves me a good bit on travel cost & time).

Cases all cleaned up and ready to assemble as soon as the rod bearings arrive and I get the rods bolted up to the crank. Everything else is ready-

Paul, this is starting to look real good. Can you make any money doing this? I'm thinking of changing careers!
