Peter ConnanExcellent work!
If you don't mind me asking, what does RCH stand for?
And did you make the ball-turning attachment yourself?

RCH is a universal unit of measurement that works equally well in both the Imperial and Metric systems, and is most often heard used in the construction trades, but works well in the Gunmaker's shop also. It's origin of use as a unit of distance is unknown, but most likely developed by the Irish.
Yes, my son made the ball turning tool in our shop.

gasgunnerCommon in the printing industry as well. We had a particularly attractive red haired customer service gal named Rhonda..........
Just giv"er another R Sam.

Duane Wiebe (CG&R)Tha's nice...very traditional appearance. Did you ever get those screw on butt swivels doped out. I sure like your banded swivel design.

BitterrootDuane,
I have the Dakota/Ken Howell-design inletted studs.

I laughed out loud about your RCH comment and yes, it's truly universal and very descriptive.
BTW: fantastic work, sir.

Yep...they're nice..fact is I bought a bunch. However, they do not match up with Gas gunners banded swivel eyes...HAR..You know how it goes.

BitterrootWhat is the difference, hole size?
If Gasgunner and I could get in sync we'd make a killing.

JamesStamboughI hadn’t heard the term RCH since Firecontrol “A” school in 1990. One of our civilian instructors was an older man that could very profane when describing current levels in various circuits. Definitely means something very fine.

Well done.

Duane Wiebe (CG&R)Ahhh Now...can you make me one in a banded version ? HAR! Just kiddin
Nice machining!

I'm not sure if it's the best way but it was the first thing that came to mind.

jplNice Work! Thanks for sharing it with us. So would frog's hair be a smaller unit of measure?

Peter ConnanLovely work!
I do think there is an easier way though. So if I may, perhaps it can be of use in the future:
On a couple of occasions recently I had to make bases that fit on round surfaces. The method I came up with was to use a ball-nose end mill of smaller size than the finish diameter in multiple passes with a small change in depth and a somewhat larger change in the Y-axis. Actual shifts are of course carefully calculated in CAD software.
If enough passes are made this results in a surface which is very close to correct and can be corrected by sanding on a mandrel in just a couple of minutes.

It doesn't get any easier than boring a hole, to the perfect diameter, that doesn't need any sanding to make it fit.
Yes, your method works for cutting the bottom of quarter ribs or front and rear sights and such, but you can hold those parts in a vise while you make your cuts. This part, no. The head-scratching issue of making many parts is not "how do I machine it, but how do I hold it?"
03 February 2023, 07:13
Peter ConnanI'm not saying boring the hole was difficult. But I do feel it created a whole lot of after-work.
I do admit that doing it mmy way would require a change in the order of the work and another method to form the ball.
Whatever, there are many ways to skin a cat, and your method certainly resulted in a beautiful product.

In the machining world that’s the understatement of the century.
