About two weeks 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 a Model A engine rebuilt 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.

The videos can be found here:

Found it odd he hadn't zeroed the dial indicator...makes it simpler to to find center without adding and subtrackting numbers...A torch can be of use if you know what you doing...
"Magna Fluxing" is a trade name...Often used...It's known as "Magnetic Particle Testing"...To those with non-destructive testing experience...

Crankshaft grinding...Didn't observe dressing the wheel...Did get a good finish...Us old timer's usually let the the machine run for 15 minutes or so, to warm up the machine...And let it "spark out" to get desired size and finish...
