I think the groove at the head of the bushing is just to relieve the nose radius of the insert, in case you have a truly square shoulder on the pulley bore.
I is interesting that you say they don't use 1/16 increment shafting over 1 inch, most of the shafting in the plant I work at is 1-3/16, 1-7/16 or 1-15/16. It does seem odd to not use a more even size though. Great videos they are very informative and educational.
Hi Keith, was there any adverse effect from the broach shims not being as long as the bushing you made? Just thinking it might let the cutting force reduce at the bottom of the cut on the 2nd & 3rd passes and maybe give you a tapered keyway...which if I understood the first video in this series was the problem that led to you having to reproduce the pulley. Thanks for the videos! I'm learning a lot. -- Mike
***** As far as I know, that is called a double-acting vise, because both jaws move either towards or away from center. They are commonly used for cherrying operations, such as making a bullet mould, where you need half of a formed hole in each half of the mould block.
Gotta ask...how many times have you crashed tooling into the lathe chuck? I mean wow...looks to be about 1/16" away from those lathe jaws...Yet another reason I probably don't have these kinds of tools...between my wife not allowing it, and my fear of destroying it...ugh.
Keith you don't have a clue on how to find Center of that shaft. That vise would put marks in your outside diameter. Kurt vise is the way to machine that.
+Paul S I have come a long way with my audio in my videos since these earlier ones were made. Upgraded mics and a few other tricks. It is a process of learning!
AWESOME video. I'm NOT a machinist, but had wondered how this was done. Thanks for sharing!

is there a storm inside the shop.

Should the shim be as long as the workpiece to prevent flexing the broach?
Not necessary. The shim only has to be a couple of inches long.
Good job !
Hi Keith, Nice job as usual, I really like that milling vice, any chance there is a name or trademark on it?

I can't say that it has never happened, but with some practice, you get pretty good at stopping it in time....
18:14 Surface grinder project!
When indicting the vise it's obvious there's damage and wear on the top edge. Why not use the next edge down which has been more protected from abuse?
Log splitter???

Who wants to donate an air over hydraulic jack to Keith?
Somebody has already done this!
That background audio noise is awful. Otherwise, good video!
