You may be able to source 20 tooth pinion wire. With a 20 tooth it won't matter 32 DP or 0.8 Mod. Pinion wire is fast just bore and part off to length. Press it onto the shaft. You can also turn a shoulder for set screws if it needs to come apart later.
Before I bought a set of 0.8 module cutters I used 32 DP cutters and metric OD... this kept my center to center distance correct.

Emphasis added. Thanks Dan and Randy for correcting me.
I don't know how much of a safety factor chain manufacturers build into these ratings. I've got empirical evidence to demonstrate that it's not 5, however. - Tristan Lall [more]
