Re: Roller bearing drop gears
I saw pics of one used set about a year ago but none in real. Will dig out the pics later

This one is an A+ type, the conversion is my own brew. I've done a few of these and so far, seem to be working well.
Years back, Jack Knight offered them for A types.

Re: Roller bearing drop gears
Please excuse me if I am stating the obvious. But doesn't it make more sense having a roller bearing helical idler gear than a straight cut one. Surely it is the side loading on these gears that is always the most important thing influencing their performance.

Re: Roller bearing drop gears
Yes, the side thrust is the bigger issues I've found with helical idlers. That is a pair of Tapered Rollers with a spacer between them in those that I've done. There is though a type of Cylindrical Roller, similar to those used in the Straight Cut gears, that can take side thrust, but those I looked it were marginal for thrust loading in this application.
