Minnie Traction Engine (1" scale)

I watch a vid a couple days ago of a guy stacking two plates in the vice then drilling a hole between them to the rivet length desired, He placed the rod and a flat washer over it for max length then cut it off, if it’s for a flat rivet counterbore to the head dimensions slip in the rod.and flatten with a hammer or a concave form for round heads.
 
Thanks again for all the kind feedback.

Is the crank machined from cast or built up?

The crank is built-up. The webs were silver soldered to a full length shaft and the connecting rod shaft. The excess shaft between the webs was then cut away.
 
A lot, if not all old gunsmith "how to" books I have, mention an excellent "heat sink" for small parts that are very fragile to change in metallurgy , they all recommend a simple apple as a heat sink, easy to push the part into the mass just the right depth and leaves no unprotected area's.
