You're going well i must say. I used a homemade 20 ton press you wouldn't want to see haha. Use a 20 ton old hydraulic bottle jack in a homemade frame [kids wonder where there trampoline went when it died--rusted away]. I true mine in between centers--well not exactly like that--as most of mine the threaded mag end has been brutalized by someone & isn't dead central anymore. So i use a drill chuck in the lathe tail stock & open the jaws then get it 'just' up onto the taper but before the keyway & lightly clamped but loose enough to turn easy, but no play. Use a center in the lathe 3 jaw chuck stationary. Works for me, with a dial gauge. Ya very lucky your mag side thread isn't bent. I get them as close as i can pressing them up then use a steel ruler across them to get 'that close' with a copper hammer & eyeometer to the ruler. Then as i said, in the lathe with dial gauge. Sorry, gosh that was mostly a long winded way of saying 'i do similar to you' & works for me!!.

Discovered the big end bearing cage had desentigrated but bearing and crank pin wasn’t too bad . Bottom doesn’t look to have been ever apart. I thought my press was 20 ton but it’s only a 12ton but got the job done anyway.

    Got crank assembly squared away yesterday and put back in the engine case with all new bearings and seals. Had to get creative putting the crank back in the left case. Used a lawnmower blade and some parallel bars to pull it in. Need to go get some case half sealant now.

Thanks guys. I spot painted the frame and swing arm while it was stripped down. Tons of new parts $$$$, but no one makes bikes like these anymore as you all know. I can’t even get a leg over the new bikes.
