Freedom Arms Line Bored Cylinder

[Fullmetaljacket]

I'm not a big single action revolver enthusiast but I've always admired the Freedom Arms models. One of the features I've read that they have is a "line bored cylinder". I've gleaned that it is the process used to bore the chambers that ensures perfect alignment with the bore. What exactly is this process?

In theory, they put the cylinder in the frame, and use drill bushings in place of the barrel to drill and ream the holes in the cylinder. Then remove the drill bushing and install the barrel. In actual production, they probably put the cylinder in a frame-like fixture to drill and ream them. However it's done, the result is a very accurate revolver.

I've seen "line boring" in large industrial practice. Basically, they're aligning the work piece by blueprint reference points to perform machine operations. Watching electrical base load generator casings being precision faced and bored is jaw dropping.

Post 2 probably has the production system pretty close. They'd be using the cylinder pin bore as one reference, the charge holes may have a pilot hole already in place if they're actually boring the charge holes. It also could be the work is done on a multi-axis CNC machining center.

I had a 454 Premier model years ago. FA revolvers are top notch in all aspects. They do lock up like the proverbial vault.

I'd like to get another, this time in 41 mag.

Just to whet your whistle, here is my FA83 in 44 Mag. I love this gun:

If you have never handled one of these up close, the precision is ridiculous. You won't see closer tolerances anywhere.

I would absolutely love to see Freedom Arms build a large frame, double-action hand ejector. Korth is never getting my money but Freedom certainly might.
