Can't find correctly sized gear

I've also tried finding alternate shafts for the P60 that would work with the current gear setup but to no avail.

Could someone help me find some gears or a new shaft?

McMaster sells a the right gear 32T, 20DP, 14.5Deg Pressure angle

But you will have to open up the hole to 1/2 inch (it comes 3/8 stock) and then you have to buy this collar & this broach & shim and broach the 1/8" keyway in the 1/2" hole.

Alternatively, you could use a VersaPlanetary but you'd have to change center distances because you still wouldn't have a gearset that added up to the same number of teeth (29+32=61 -- Vex doesn't sell many/any gears with odd numbers of teeth).

Actually, I just now realized that I assumed that you wanted the P60 to be driving the 32T gear. If that is wrong. Then I will have to change my answer.

Good luck.
