Hi folks!
I'm designing a super simple 5:1 belt reduction for NEMA 23 steppers to drive pinion gears for rack&pinion setup.
The problem I'm running into is that all the pinions that suit my application have 1/2" bores, and all the MXL or XL timing pulleys have 1/4" or 3/8" bores!
Does anyone have any suggestions on what to use as a countershaft? Otherwise it looks like I'm stuck machining one, which I was hoping to avoid
