Where can you get them? I haven't seen them listed for sale in a long time.

Can you order new custom pistons with buttons instead of locks? Also can you use buttons on pistons already set up for locks without changing pins?

The reason "buttons" dont get much attention, is the simple fact that most have no idea what they are, or how they work. I think buttons are 3.00 per piston from Diamond, or maybe 3.00 each, but regardless, they are cheap. They can't be used on a super lite "slipper skirt" style piston, but other than that, they are good for any combo with full skirted pistons, which most are.

after reading this thread, i can't believe i haven't been using 'em. we used them in model airplane engines- bulletproof.
for what is the good life if not doing things thoughtfully?

Our pistons always have the pin up in the oil ring. Low deck.

Venolia does a good job with wedge and hemi pistons, buttons are pretty normal with them.
Also, they can "cam grind" the skirts. Very few manufacturer's do this any more. It only matters if you make big power.
