Thread: Shotgun Stock CNC Build

Thought I'd throw up some photos of a buttstock and fore-end I've been making out of some nice chocolatey (is that a word?) walnut I was given.
I'd previously done a trial set out of some macrocarpa, just as a test to make sure the shape and fit were correct.
The test set was also made from one thick slab, but with this set, I had two small pieces that were bookmatched, but would have to be made in two halves.

Here's what the models look like, with some reference images and a lot of rough measuring to make sure I was in the ballpark. Also for those interested, the CNC toolpaths on the models.






First I cut the inside of the butt section, machining the groove for the bolt and the gap for the action to fit into.
I cut the bolt hole length too short, kind of on purpose, thinking I could just drill more out once it was together, but in hindsight I should have just trusted my measurements.
I also machined locating holes that I could use to flip and locate the part on the machine, but also to glue the two halves together.
Everything was cut slightly oversize so it could be fit to the action by hand. A few small issues but overall, not too bad.




Then machining the other side.

Then copy and paste a mirrored part.
