Shorten lathe chuck jaws...

[Dhofstetter2008]

I cut down a "dog leg" setup that came with my grizzly and made that work. I use #4 copper wire which fits pretty well into the grooves I put in the heads. I also use the extreme pressure grease between the "heads" and the bolts so they dont tend to bind up as much.

After watching Alex's video it inspired me to change my setup and try and make things run as best I can.

Here's what I came up with.....

I pulled the brass tips off the 3/8x24 screws then cut them down and drilled the end with a 1/4" ball end mill.

This thing is rock solid now and so much easier to dial barrels in with.

After changing to the pivoting feet, I know for a fact I was bending barrels to get them dialed in. After seeing how this works and how rock solid it is I'm very excited to chamber up my next barrel.

Looks like Bamban's on the #27 thread. It should work.

So from the more experienced smiths when your dialing in on the jack bolts then as far in as the dti will reach what kinda run out are you seeing at the muzzle?

Mine still seems excessive at .060" am I still bending the barrel with my setup? Or do I have a very curved bore?

Something is wrong in your setup.

I have a quick question about the "Wheeler" method. On the feet that touch the barrel you guys are cutting the pockets with ball end mills, would it be detrimental to the overall quality to just have a bevel and not a round hole? Im thinking that the round hole cant actually have 100% contact with the ball and a bevel of 45 degrees or something would still have a ring of contact and allow free movement.Possibly more contact than the round hole sense if its not perfect you'll only have a point or 3 of contact anyway.
Am I tracking correct or way off base?



Secondary if you'd make me some feet relatively inexpensive please shoot me a pm I dont have a mill or access to one readily. I can make the bevel style in my lathe with some creative 4 jaw set up
