Making a KP Stock, have some questions

[cougar20th]

So I'm starting a project to restock my KP3 with something unique. Don't want to modify my original stock incase I screw up. So I will be starting with a block of wood. Wondering how do people get the round cut into the wood where the gun tubes sit? Its about the only part I haven't figured out.

I do have a pretty well stocked woodshop as far as tools and what I don't have here I may have at my mothers house. As I keep two woodshops.

I used a 1" DIA router bit. I tossed it on my bridgeport but a router table and fence should be fine.

Awesome that is what I was thinking, Routertable cut as far back as I can and then finish by hand. My KP is one of the flat backed so I think the cut cant be run out the back of the stock.

Aren't the lower tubes on brass 7/8"? Or was the 1" for "wiggle room" for fitment?

I think you are correct. You could use a 7/8 if you could find one. The 1 inch is a bit expensive to start with.

Also, the larger bit doubles up on the pump handle, if you make one. It gives you some space there.

I honestly use a two flute ball end mill.

I used a mill and a 2 flute 1'' diameter end mill when i had a mill.
I also used a table saw as a guerrilla method - a polish hammer if you will. Finished with a dowel and sandpaper and chisels. A real hack job.

I like Boyd's, but just fyi the laminate is heavy. Stable and stout, but heavy.

Yeah- I have a Mosin and missed the boat on the cheaper walnut stocks from Boyds. I did catch the Mosin and a 440 rd spam can of ammo for less than $200 otd however. Not really a fan of laminate, but at least it's not plastic.

A friend of mine is Reed Sherman who designed the Jart series of R/C sailplanes. The Jart uses the "lost-foam" method of making a fiberglass fuselage. You carve the shape you want out of a sheet of 2" blue foam, cover it in packing tape, fiberglass it, then drill a hole and dribble in some acetone- the foam melts, and you drag the tape and foam goop mess out of a hole- you could use the area in the barrel channel, or under the butt plate. Then you apply a skim of bondo, sand, putty, paint. Fairly inexpensive way to make something this size and shape: Jart - Build Thread - RC Groups

Here's a video of Reed flying the first Jart at a spot in Nor Cal: JART — The Original - YouTube

Yes- he's just that good.

I have thought of that and a variation may be another project in the future. My big concern is expense the way I want to do it and it creates do drum.

for inletting, I just draw the width lines & make 3 passes with a 7/8" half round in a router, then clean it up with a sandpaper wrapped scrap of brass.
