I am getting ready to make a spider for the rear end of the spindle. I want to thread the spider to fit the threads of the spindle. I have some 3 inch OD aluminum for the frame, and I have been practicing cutting internal threads.
My delema is how to check the threads to see if they will fit. Or another way of putting it would be, if they don't fit, what is the best set-up to work from so I can re-index the spider to cut the threads larger? I realize you guys would hit the mark the first time, but I don't have that kind of experience or confidence at this point.
Checking with a dial indicator and using the 3 jaw, when I put the aluminum piece back in the same place, I am getting .0015 out of round. That is the best I can do.
I could guess my way through this and probably get something usable, but I would like to know what is the PROPER set up and procedure to use.
Thanks.
