like the title says what tradeoffs are involved in making a gear from brass vs steel vs plastic?
You’ve gotten good responses so far, but it might help to know what you want the gear for.like the title says what tradeoffs are involved in making a gear from brass vs steel vs plastic?
I have a mini mill G0758 that has a H/L shift in the head and it has all plastic gears 1 outside of the head but 2 that are inside the head and a PITA to replace, I'm investigating upgrading the motor and will need to address the plastic gears since they break even with stock power. no one makes steel replacements and I think i can build them myself but just trying to get an handle on noise/wear/strength for the materials. there is one gear in the mix that is easily (relativity) to replace and i may make that one sacrificial. i'm also looking at changing the ratios. i could do a belt mod but i like being able to switch H/L on the fly.You’ve gotten good responses so far, but it might help to know what you want the gear for.
