Piston teeth?

MagicIRL

What's the difference between pistons with different numbers of teeth and how much teeth would you want to be steel when upgrading a gearbox for higher ROF?

on my high ROF setups i use these. nearly unbreakable.

on the high ROF i prefere to use full metal teeth pistons with the second tooth removed like the one above.

I've seen some pistons that only use the first two or three teeth in steel, the rest being whatever material the actual piston is made of. What's the difference between those and say the one you linked above?

some pistons have a couple of steel teeth next to the piston head, because as the piston is wound back to the rear on its cycle that the teeth next to the piston head are under the most strain due the spring being under the most compression. the idea of leaving some teeth plastic is these are the weak link so if the gearbox locks up or something goes wrong only the piston gets broken and not the whole gearset.

AH! Makes so much more sense! Cheers man.
