No offence taken Jerry.

In answer to your question about splining a shaft, no I haven’t, and frankly would not have thought about doing it had I not come across an couple of posts on other sites were guys had used die grinders to extend the splines. I’m not sure exactly how they went about it but here are my thoughts.


I would not even consider trying it free hand. I was thinking I could make a sleeve that just fit the input shaft with a slot cut to the right width to act as a guide and a locking bolt to hold it in place. I would use a small cutoff wheel to on the die grinder to extend the splines. I’ve got a few old input shafts sitting around and figured I grab one to try it out before I actually did the T5 shaft.


The adapter plates are up in the $170 range now and would be a no brainer if I was building a customer car ……..the amount of time I’ll have in doing this would outweigh the cost of the adapter. Since this is a case where it’s for one of my projects and I have a bunch of time anyway, I’m still leaning towards giving it a shot.
