Fitting up a Badger 306-02 M700 this am. Thought you guys might like to see how I go about this a virgin stock.
Enjoy.

This vid is kinda thrown together. I always start "shallow" and work down till stuff catches up with one another. (meaning the part fits up nice with the stock)
So, some might be a little redundant as you'll see features being cut more than once.
One neat addition I've been working on is the surfacing of the arc radius where the trigger bow portion of the floor metal flows into the rear of the magazine box. I've always wanted to have the mirrored radius machined into the stock. Serves no purpose really, but it looks pretty cool once its done. Much nicer than the blown out relief that's been the norm. As time allows I'll work on adding this to other inlet programs.
Another item that's been working well is the revision of the trigger bow inlet. What would seem as the easiest part, is actually a bit more complicated.
If you look at the fixture you can get a pretty good idea on how everything is clamped up. The rear guard screw location is essentially in "space" as there's no direct fixture contact the way there is on the front.
Because I do the inlet in one setup and use the multi axis capabilities of the machine to do the work it presents a challenge when you machine the pillar. When moving in a positive Z direction (down to up) it's pretty easy. Your continuously reducing the tool pressure on the pillar. However when the tool goes past the midpoint of the arc at the back of the trigger bow (right in front of the grip) it begins to transition in a negative Z direction. (up to down)
This downward pressure causes the stock to flex a bit as the tool moves across the pillar. Once it's past the pillar the stock "snaps back" and causes a shallow gouge in the floor of the inlet. It's always bugged the chit out of me so a few weeks ago I went about resolving it.
Now the tool moves only in a positive Z fashion. I just split the tool path into two segments. Climb cutting on one side (closest in the vid) and conventional milling on the other.
Not super exciting, but it makes life easier and the parts come out better.
Enjoy,
The file sizes are pretty big so as they load to photobucket I'll update.
