Chambering short barrels in the headstock

At least it's not very messy

I’ve been cleaning up constantly in the process. Like you I’ve filled a large container with chips.

Cutting the slots for bolt handles. It’s a slow process. Sure glad I am not making this out of steel!

It’s 5” OD and 2” ID x 7” long. With the backplate it’s about 8” overall.

I noticed that you chamfered that transition.


That fixture looks great! Awesome work.

Annular cutters and that slot is cut in 5 minutes.

I’ll have to look into some of those. That would have saved some time for sure!

Got the machining all done. I ended up putting some extra hole sets in while it was all set up in the mill. Easier now than trying to set it up again later if I needed additional positions.

Now I need to make some brass tips for the screws

Did you use a backplate, or mound studs directly to your fixture?

I used the same backplate as you did from Grizzly.

I went with three bolts that are 3/8x16, and they reach 1.5” into the aluminum. Spider holes are all 3/8 x 24.

Since the fixture is @1.5” thick, with 1.5” grub screws there will be no screw head ever protruding from the fixture just as an added safety measure.
