Engine Rebuild

[spinelll]

I posted this on the "Early" forum. I thought the "Late" guys might also find it interesting:

A week ago I had the great pleasure of spending a few hours watching the craftsmen at J&M Machine in Massachusetts do their thing. My buddy is having his ’28 engine redone there and I tagged along for the 3 hour ride from Rockland County NY. We’re Model A owners but J&M’s business appears to be engines of any kind. Flathead V8s, Packards, TBirds, V12s, Trucks, Tractors, Marine engines… You name it, they rebuild it. I brought along a camera and recorded a few operations for your viewing pleasure.

Oh, and in case you’re wondering, I have no affiliation or monetary interest in J&M. I’m just a garden variety office worker and gearhead wanna be who appreciates fine art.

Thank you for taking the time to do this. Many of us have paid to have these things done, yet never seen it done.

Here's a little taste of a babbitt pour at J&M.
