Hi everyone,
I've decided to finally attempt to build my own custom stock for my CFX. I really hate the factory plastic factory stock and wanted something similar to the stock on my .22 target rifle. I finally got the right piece of wood today and I'm ready to start working on. So I would like to know how in the world your supposed to cut out the inletting for the gun. I've made plenty of measurements and have a full scale drawing of it all but don't how in the world I'm actually gona cut it out precisely. I guess I'll end up using a router but not before I practice with it a good bit.
Thanks
Brian

Bryan, that's what I use, a router with a 1/2" straight bit and a 3/4" cove bit. Just go slow and take alittle at a time, after practicing on many,many scrap peices first.You have to be very careful and not get the zslots for the cocking rollers too deep, or it will not cock.

A router will be your BEST friend!
I haven't inletted any airgun stocks yet, but I've done plenty for 10/22's and a few others. For stuff like the trigger opening and the stepped parts inside the inletting I used to use a drill press & a forstner bit just slightly smaller than what the finished cavity was supposed to be. Just drill, move, drill, move etc... Just nibbling along then use a nice SHARP chisel to clean up the corners.
For the longer parts I used to measure the depth of the barrel channel (or chamber channel in this case) and set my table saw to a hair under that depth, set my fence & rip down to my stop point. You can route a barrel channel with a table saw, but it'd take a good amount of time. Hence the 1 inch cove bit & router! hehe
Good Luck!!! and most importantly HAVE FUN!!!

When I did mine, I made a jig. I clamped the stock upright between two other 2x boards andattached 2x to the ends and clamped on longer 2xs for the rails to guide the router. picture here

I made square blocks that were the same witdh as from the edge of the router to the edge of the cutting bit. I laid out what I wanted cut out the stock and used the blocks to set the longer 2x guid rails so the router would not cut too much. This worked out really well. A caliper (my is digital from harbor freight for $16) is the best investment that I made before I started this project.
Here is the route up agianst the guide rail. (NOTE: I ran the guide rails though my table saw to straighted them out before I used them.)

Hey Martin. Good stuff. Much easier to do the inletting first when you have a straight sided blank. Truing up the raw wood with a couple of passes through the table saw and leaving it a bit oversize also helps. You can retouch up the centereing of the inletting if its off by skimming the wide side till you get it even. Thanks.

Definitely use solid guides & guide stops for ALL of your router cuts to avoid unsightly wood filler. Also you may find it useful to establish datum lines on the wood for X,Y & Z axis. These datum lines & points will allow you to reference or accurately copy dimensions from your factory stock to your custom wood. Recommend that "X" axis be length-wise centerline.
Go Slow - Measure Twice - Cut Once.
A sharp chisel will shave hair. If you do not have a fine india bench stone & a hard Arkansas stone, this would be a mighty fine excuse to get one.
Good Luck
