    Granny,

    Nice looking part.

    It's aluminum? Is that going to be up to the job? All the CV flanges I've seen used high strength bolts and a pretty good torque. Will the aluminum in there loosen up in use?

    I have finally been able to finish a project I've been working on for a while. I have a small mill as well and spent a few minutes here and there on my SB 9a lathe (some time on the mill too, I hope that's allowed) and finished this boring head for my mill.
    No way was I going to spend a couple hundred bucks on a small boring head so I just spent a way more time that I would like to count to make one. ha. Good thing time isn't money... oh wait.

    I made this out of stainless and I'm pretty happy with the results. img_1510.jpg

    Yes aluminum, the bolts are metric 10.9 grade. I guess I'll find out if it will hold up, I'm not a rev it up and drop the clutch kind of guy.

    Just don't put huge tires on it,when they are spinning they won't break anything,when they hookup is when something breaks.

    In a factory setup, those high grade screws are clamping the steel CV joint to a steel flange. The resistance to the joint twisting comes from the friction between the mating surfaces, the result of the clamping force of the screws. The screws do not transfer the driveshaft / axle torque.

    My concern is that your aluminum adapter will mush out under the screw heads, so you will not get the high clamping load and resultant friction at the flange. And every time there's a high torque applied it's wiggle a little. Getting worse and worse over (a relatively short) time.

    I would recheck the screw torque after running it a while and keep an eye on it.
    If the screws don't loosen up, then you're good.
