Good stuff, all the little things add up.

The best machinist I know taught me that slow and steady wins the race when it comes to machining.

As a kid I always hung out with old guys in the shops I picked up a lot that way when I was a kid

As usual, excellent work Charlie!

Used to fool with old mopars every set of heads I'd tore down had knurled valve guides never seen it done on a piston

My dad was huge into MG-Austin Healey 3000’s and we’d open up a motor and find knurled pistons. On my recent Makita 5000 build I cut horizontal oil lines on that ex skirt. About 2-3 thou deep and I go edge to edge those grooves aren’t enough to make a difference In performance. Also chamfer the piston edges and specifically the skirt bottoms so they don’t act like a scraper and wipe the bore clean when hot. Small details like these can really help. Cool stuff

Great info and work 👍🏻!! you the man Brisco.

Now to machine a whole engine design. Like a rotary wankel chainsaw, that would be an amazing feat. Also Mahle was a good piston company.

Super cool piston mod 👍

👍👍 good stuff Charles!

U watched that piston knurl video too? Lol ol Smokey tricks.

@@CharlesBrisco smokey would do that on some of his race motor builds... the idea was multifaceted... oil retention and keeping the ring contact patch proper.
