I need to broach some bushings on a clock.I was wondering could i take a twist drill of the diameter i need and grind the lead off the end of it to use to size my bushings?
The main thing i would think is the finish of the hole may not be smooth enough for the pivot to run in.
I hope some good clock people out there can help me.
Kevin, there are 5 sided cutting broaches in various sizes for enlarging the hole in your bushings. You should use a smooth broach for burnishing the hole. A drill bit would leave too rough a finish in the hole.
Thanks Tom, guess i will wait till saturday to broach my bushings at my course.
Keep us updated on how it goes.
