Done! This is as far as the prototype needs to go. Next step is to see about having a shift boot made for it that can fit various cars or someone can adapt their existing boot with a little creativity. If the boot works, then I'll either have my client bore the holes that make it fit the 924/944/968.... for further testing. After that, if it works, I'll have them make a handful of pre-production bushings for even more testing.
I think it took a little over 4 hours to hand turn this. And no, it's not bent in the bottom pic, iPhone artifact.
A bit of chatter in the groove. I had to use a 1/16" wide, HSS parting tool that is normally used on wood.
