is there anything special about fighting bro pinions?
pitch? depth? diameter?
I built for a mate into a wells some FB 16:1 and he’s got one of those comfortable molded grips. He didn’t have a specific FB pinion for me.
Shimmed quite nicely, pretty standard bearings into a wells box. No shims under the bevel, it’s a s low as it goes. The bearings sit in, not tight, not loose…pretty normal.
First build I noticed that the motor height was about half contact with the bevel. I didn’t like it. It was far too tight, it went to the field and shagged the pinion… no surprise.
Take two…he gave me another pinion, seems to mesh ok but not perfectly and again, half contact…
Hours later I’ve swapped the grip for a stock grip, dropped in my old wells bevel and still the best I can get is a poofteenth more contact with the bevel, seems excessively stiff.
It’s a sticking point for this build…no decent pinion height == now pew pew and I just need this wretched thing off the bench
