WOW! What a day. Lots of parts to ship.
Anyone who is following the thread knows the Trigo pins I measured were at 76 degrees. I assumed (very BAD thing to do) they were a standard 82 degree taper and so we made about 100 of them at 82 degrees. When things started to not look right, I busted out the angle gauge and found I was a dummy...and so was someone else. The tapers on the pins were 76 degrees??? WTH (For you non-Utah people, that means "What the Heck."
We later found out the Trigo hub adapters have a 90 degree countersink in them. Someone had a little too much weed when they were making thos pins.
So, we had a bunch of bum parts. Concentricity, is critical in this part (along with most parts) so we specially machined the jaws on the lathe to fit a collet chuck. We then chucked the pins up in the collet chuck to make sure they were absolutely straight, and we corrected the taper to 90 degrees. Bummer to machine the parts when they are already hard, but carbide doesn't really care too much. You just have to go a bit slower.
