M22 transmissions

[scuncio]

I wonder if AutoGear would make you a set of straight cut gears. If so, I am sure they'd be expensive.

I believe DNE (Doug Nash) made a pro-shifted gearset for the Muncie. I have seen DNE pro-shifted T10 gearsets. Not sure what helix angle was used in these but I gather it's a straighter angle like the M22, or possibly straighter yet. Keep in mind that straightening the helix angle will only increase the separating forces between the mainshaft and cluster gear, with a corresponding decrease in thrust (and probably a decrease in friction, but whether that's measurable is TBD). Ironically, many of the Muncie's problems stem from the separating forces between the mainshaft and cluster gear (case stretching), so are we really "fixing" anything by using the M22 helix angle? Just something to consider.

The Super Case, or the DNE cast-iron case, is probably the best bet for fixing the 'case stretch' issue.

(Note: I am not a transmission specialist and these are only my thoughts!)
