Thread: Adaptor shaft

This morning I visited a toolmaker machinist a German who has a very good reputation I showed him pictures of Grubs shaft complete+ modified versions also my spare shaft His comments, mine in brackets
Grubs Design No probs if 4340 should be nitrided and not thru hardened with misalignment being the probable cause either the case or the shaft not true
(I would rather see a more gentle transition from large to small diam and thru hardened ) My shaft again no probs but should be nitrided instead of thru hardened due to distortion I said my shaft has only .002"runout .He said but .002" is .002" (bloody Germans) Any way he is going to work out a price for shaft and splined flange I don't think it will cheep but will be first class

Expressions of interest?

Thanks AM for the info. You did not get his views on the Outcast shaft then?

I would be interested in a drive flange and several spare floating shafts, provided I can use it in the Outcast case. I Presume this will be possible. From memory Sheldons case was 175mm and Outcast is 173mm length.

My transfer case is 1.222.

For me the SAE10 spline would have to be long enough to accommodate the long spline input gear. I would think that if the floating shaft had the long spine then in would suit both long and short spline input gears.

I was hoping you might answer a few questions for me on the link below, but you have been busy elsewhere (gratefully). I have been emailing a machine shop in Brisbane for a quote but need to work out a few details in basic design, with them figuring out the finer details. He indicated a one off would be less than $1,000, but probably conventionly milled rather than CNC. But if a few were ordered then CNC would be the go and costs greatly reduced. I also advised the owner that given this is a national forum guys may choose to use someone in their own state. If we want to get costs down then we need to bump up the numbers and commit.

Your short hand sometimes leaves me asking more questions . Your thread here seems to indicate that the shaft needs to be through hardened and cryo treated. That Damiens may have lacked the through hardening and along with possible misalignment caused failure.

Does your friend design casings as well - not sure some of you may have to look at this issue again - hope not.

PS my mans a South African, but still of the pedantic Germanic grouping.
