Lathe Spiders

[ELR LVR]

4 Jaw and 8 ga. Copper Wire for the front, No special attachment needed
Barrel can pviot on the round profile of the copper for alignment
The Copper being soft, gives good bite into the barrel without marring the finish
---
For the rear - Threaded 4 screw Collar
Brass pointed screws, (Same concept as copper but does not need to bite in the rear, only support)
---
Now for a guy to make a superior awesome attachment for like a D1-4 on the front
(2) sets of 4 screws, spaced about 4 inches apart
So a person could dial in short barrels or even pistol barrels without having to use a rear spider

The benefits of the front spider is it’s significantly shorter than a chuck, you can use it with pivoting V-blocks that hold very well, and there’s no need for sacrificial parts like a copper ring.

I’ve used a spider with 2 sets of 4 set screws and it worked, but wasn’t my favorite thing. I like the idea of having the muzzle end supported with the dual spider setup.

There’s a million ways to skin a cat. This is just one way.
