Cutting/shaping Cloverleaf Tange for M70 Classic

Siam_KragCutting/shaping Cloverleaf Tange for M70 Classic
All right I was wonder how folks go about doing this. I asked this question to a very good stock-maker and he told me to make a template and file it it. I think there has to be a better way to do it with a milling machine with some type of shaping cutter? I have seen some done that obviously look like they just went in with an end mill on the x axis then backed out on the y axis. Then I have seen some nice ones done with complex curves is the only way I can describe it. Just curious on how to get that good complex curve look.
I know at least one excellent gunmaker that reshapes with a prototrak mill.

Siam_KragSo, I just went to James Anderson webpage and it appears that he uses a CNC to cut his.

Lord FrithCheck with Al Lind via the ACGS-or some other acronym-for his contact information. The guy is a master with few peers.

Bill LeeperI just use a 3/8 cutter and duplicate the pre-war tang. I use an Etch-a-sketch technique to get the outside curve and let the cutter diameter establish the inside curve and finish with a file; undercutting slightly. I was making them exact but was asked to make the tang a bit bigger to ensure a tight fit in a pre-inlet stock so I leave it about .020" wide at the tang. Regards, Bill.

You are absolutely right; in the old days, the first tool taught and practiced was the file. Nowadays, everyone's first thought is the computer. Last month I had a master level "Machinist" who works for a large company, ask me to teach him how to thread and chamber a barrel. I told him that he should already know how, given all the training he had. He said they were really machine operators with little experience on hand work. Sad.

zimbabweWhen I entered TSJC in 1952 our first project was to make machinist square. You were given a piece of 1/8" flatiron and required to cut an 'L' shaped piece and 2 rectangles for the square. The rectangles were riveted to each side of the short leg and you then proceeded to file a square square - by that I mean ALL angles square. I got all the squares but slightly missed the dimensions so just got a passing grade. They actually taught you what a file was used for. I'm looking at it now as I have used it regularly all these years. I think the next project was to make a flat spring. I needed a mainspring for an 1886 with set trigger so that's what I made. It's a special as half of the side needs to be cutaway for clearance of the set trigger. Passed that one with a perfect score. Such was the training then.

AtkinsonI just rough file it, then finish with a fine tooth file, paper then hones...
Just cut to the actual tang, all they did was add a bunch of flat metal to the original Mod. 70 clover leaf, why I have no idea, but when you remove it you have a clover leaf....
There is a lot of filing to be done, and it should look just like a clover leaf original when finished..
Also its a pretty good idea to take it to a gunsmith or machinist and have them cut away the hard part, then finish by hand.

That is beautiful workmanship.

dave wesbrookJim you're lucky. I saw him get Gary Goudy to buy him two shots of 12yr old Scotch...Dave
They put that flange on there to hide the receiver tang inletting; they could now make it sloppy, and have a gap so wood wouldn't split at the tang like it sometimes did with a tightly inletted tang. Easier to make stocks.

Idaho SharpshooterJim,
would you give us some estimate of what such work would cost these days?
You could PM me if you prefer.
