I have heard that you can use 32p pinion with a MOD .8 spur. Does anybody here have any experience with using a set up like that? Would it cause the two gears to wear down faster?

As some of you probably know, the conversion to metric is 25.4/p. So, 32p converted to metric is 25.4/32 = 0.79375. Which is pretty much 0.8. Also, let's go the other way, to convert back into pitch it is 25.4/M. So, 25.4/0.8 = 31.75 which again is pretty close, actually only 1% difference.

So imo there would be no harm using 32p pinion with a .8 MOD.

My Feedback: (10)

yes, you can use mod .8 with 32p without issue. worst case scenario is that it may be a bit louder

The general consensus is 'compatible' but I wouldn't do it. Just my 2c.

Mod .8 or whatever is else is the metric way of measuring gears (mod is short for module). What that is measuring is the distance one tooth is from the other. For example, .8 mod would be 1 tooth for every .8cm (8 millimeters). Pitch on the other hand is the Imperial (US) way of measuring gears. I'm not exactly sure how the pitch is calculated, but it uses inches obviously. So, .8 mod and 32p are compatible in my experience, however I don't know if technically the numbers match up, but then again, don't get too caught up in the science of it. If it works, it works. Hopefully this helped.
