gixxerI need a bolt milling clamp...
I guess that's the best way to describe it. I am looking for this clamp that holds a Remington bolt in the proper position to mill out the slot for a Sako extractor. Brownells used to sell em, but no more. Any sort of help would be appreciated.

malmAll you need is a good machine vise, a set of "V" blocks and a protractor.

MasteriflemanMalm's right. All that I have done I used V blocks and the extractor packaging should come with all the dimensions of the cuts.

Jim KobeI've done literally hundreds of these and only use the mill vise.

MarkYup, V blocks are the way top go.
for every hour in front of the computer you should have 3 hours outside

I to have used v blocks to install Sako extractors. But, I much prefer and use the installation jig. For me it is a lot faster and I have better control of the bolt.

D HumbargerIf you have a pair of bolt bending blocks you can use them in your milling machine vice.. You will be able to rotate the bolt in the blocks to the exact position with ease.

Jim KobeHere are two photos of what I use. The fixture for holding it vertically is also use for holding a barrel (Ruger #1) over the edge of the table to mill the extractor cut.

They're handy for measuring and setting various angles of course.

Oh, you mean for this particular job? Well, until gixxer has gained enough experience to where he can eyeball the lug angle like you and me, he will probably need to use one so that he doesn't run into trouble, or, the lug, after centering his cutter on the bolt.

Jim KobeWhat I do, and bear with me on this, is I set the bolt in the vise, use the center finder to get the spindle centered over the bolt, move the table .088" (half the width of the cut. .156") so the spindle is now over where the edge of the slot against the lug is, and with the wiggler, rotate the bolt so it points at the juncture of bolt lug and bolt body. I then move it back to center and start. Drill first, slot next. Pretty easy with DRO.

I'm jealous. I don't have a DRO. Maybe Santa will be good to me? Jim

Jim KobeThat was wrong,"half the width of the cut" The cut is .176" wide, not .156".
