Modifying the big boring bar to make it even better!!

In this video I revise my big boring bar I made. I cut a key slot so it will positively drive the bushing and it can’t spin in it so it won’t gall. This of course meant I had to add a key provision to the bushing. I also drilled and tapped it so I could prevent it from pulling out of the bore without using a ratchet strap like I had been. I hope you enjoy and thanks for watching!
