The two and two design, makes indicating 5 groove Bartlein ppc barrels interesting
It must be a spatial thinking thing but when I used to use my 6 jaw Bison set-tru with copper wire I didn’t have any thought or trouble at all when dialing in 5R’s. I just did it??? Same with front and rear spiders that aren’t indexed/aligned together.The two and two design, makes indicating 5 groove Bartlein ppc barrels interesting
Oh man!With swivel tips!
(I sure wish these were available in fine thread)

Oh man!
Those are neat!
I considered a ball/sockets arrangement with a set screw and brass end.
Would not be too difficult to make.
Certainly can be a bit of a merry go round to indicate.The two and two design, makes indicating 5 groove Bartlein ppc barrels interesting
I never even thought about trying to align grooves with jaws. I just put the barrel in and go to work dialing it in. Even though it is individual lands and grooves I still treat it as a circle, an interrupted circle but still a circle.I know what he's saying... you can't align the grooves with the jaws/set-true bolts. Small adjustments... keep going in circles until it's right. I don't bother with aligning the grooves to my jaws..
For those of you looking at swivel screws....these are the true center grip

Might also be that I had done plenty of machining well before I did any gunsmithing so already had my head wrapped around the concepts?
Start fresh. Its good practiceYeah. I found these too late. All of my jigs and chucks are fine thread... if I were starting fresh I'd plan on using these.
