Man you would not believe the frustration I went thru while working in an aerospace machine shop. I had to drill two safety wire holes in a few thousand 6-4 Ti (AMS 4828) nuts. They were probably 5/8 or 3/4 flats. I built a hex collet with carbide bushings so I could drill, spin 180°, and drill the second one. The collet made a tight fit on the hex so the tiny drill wouldn't walk. The plan worked pretty good, but put a little too much pressure on the bit & it would disintegrate inside the the titanium. Dem wuz da good ole daze. Glad I'm retired now!
@@motomecha530 you are doing it right for low quantities. The only better way I know of is to use a (same size) flat bottom endmill, then center drill, then drill. But you would need a milling machine because an end mill would snap off if used in a drill press.
This Is just one of the steps required to prep your bike for racing. I'll be making a series of videos on all the requirements to get your bike ready for either a track day or for racing! Stay tuned!

Yikes! Yeah I was a machinist for a couple years. Really learned a lot!

Good information and useful is many other applications.
Glad you think so!
What is the safety wire for?
It's so the nut doesn't back itself out on its own. Like a tether.
@@motomecha530 very cool. Is that for track riding specifically or any riding. Thanks for the response.
Pretty sure certain track's require it.
I'm not really sure it's necessary for street riding.
