Every once in a while you'll find something on craigslist that's been owned by a machinist or engineer that's been taken care of and they sell you a machine and an education, too.
Nowadays, companies are snapping up all the used machinery before you even get a chance to make a call. then reselling it.
Sold a mill and a lathe and I think that was the case.
We still get some interesting stuff.

Laid out some string to mark the centerline and the sprocket-line and mounted the rear wheel with new bearings just barely pressed in by hand.
Centered the rear wheel as best as I could and measured the sprocket offset.
Took some measurements and I got right about same amount of offset when I measured off the marchesini wheel. Not bad for eyeballing it.
I will offset the hub carrier 3mm and try to split the difference between the sprocket and centerline and then machine the left spacer.

left spacer machined. my hub spacing ended up being only +2mm. the sprocket lines up well eyeballing it all weekend. looking at the sprocket teeth sitting in the chain, they are so very slightly offset to the right. the wheel centerline offset to left a couple mm's at least. I'm good with it. The center spacer is next.
then the rear caliper is going to need a little thought as well. this is a little more involved than i thought. the slot to locate the caliper on the swingarm wont allow the bracket to move inboard.

She's back on wheels and tires!
bigger axle meant bigger bearing ID's, bigger internal spacer, bigger hole in the wheel for the spacer to pass. finally got some time and almost finished the rear wheel conversion. Mounted some street legal DOT Rossa corsa's.
Still need to cut a short right spacer.
The rear brake is gonna wait. I'm bored of the wheel.
Next up is the subframe and seat...
Kinda dawned on me that I'm going to get nowhere with the subframe until I chose a seat and tail.
I decided to go with the 15+ R1 seat and tail.
The Armour Bodies kit is nice. It comes with a separate seat pan that is as sturdy as fuck.
It has a center section under the tail that might be perfect for the exhaust to pass.
It should be here tomorrow as well as some more 0.75"x.03" wall mild steel tubing and some 0.5"x.03" tubing.
I still haven't made the commitment to get an AC TIG to weld aluminum. But, .03" wall steel feels as light as hell. I will just have to be careful with the design to make sure it's strong enough. triangulate the whole thing.

that tail is drop dead sexy
yeah on the thinwall steel overbuild it to try to eliminate flexing
there will be quite abit of force appliedin vertical and more horizontal depend on your girth and the g forces that your cornering and bump hits generate
cromo can handle the flexing and is why it is chosen to build lighter weight chassis
becausae it has a very long life under flexure
because some flexing is ok and some is almost unavoidable
proper gussetting can help but is important to do it correctly tony foal shows it nicely in his chassis book
gussetting effrectively shortens a tube making it stiffer it can be thought of as a change in frequency
upper mounts looking pretty before welding
yeah, I'll have to get longer bolts
preview of the seat. mimicing my track bike ergos.
