Bottom Metal Inletting; care to share your method?

Hey y'all,
I've got a CDI precision detachable mag setup coming in the mail today for my 700. The rifle currently has a HS Precision PST012 stock, and I don't know if it will require inletting or not.

I've got an idea of how it all goes down; watched a few videos where a CNC mill is used. I don't have access to a CNC mill, but we do have a few plain jane Bridgeport mills. CDI will do it for $60, but my DIY bug is strong. I think as long as it's fixtured properly, there's no reason I couldn't do this in a couple days when I get a hour or so of free time.

Anyone care to share their setup for this?

Waited. Saw. And I've decided that there's not a whole lot a determined SOB can't do with a Dremel. A steady hand and three hours later, this rifle's got a detachable mag. . It works. Really really well.

Had to remove quite a bit of material. Fit was nowhere close to right. ImageUploadedByTapatalk1346291876.876957.jpg

Pretty happy with myself at the moment.

Seems you have it done,but I'll post anyway.

If you have a lot of material to move,by all means,use the Bridgeport.

For just fitting something that does not quite settle in,I coat the metal with Prussian Blue.

I put the part in place,tap it with a mallet,then pull it out.Read what the ink tells you.Think about what surfaces are intended to contact,what is the flat,square datum,etc.Know what the foundation is you are trying to set down on.

For cutters,I just use mostly stainless feeler gage stock.It comes in 12 in lengths.I use .025 or so,not critical I use a cutoff wheel to cut it,and a bench grinder to grind the shape of scraper I need.When you grind it,it makes a little burr on the scraper.That does the cutting,The scraper has a little spring to it.Just drag it across the work,it will scrape shavings.

I scrape off the spots that have prussian blue on them,then do the same thing again.Blue,try,scrape the high spots off.

Soon,more and more will be blue.Watch as the metal settles in for what function tells you.

Its a little tedious,but it works.

Mill it. It's the only way.
