Got a good start on a new stock for my MP512-M over the Memorial Day weekend. Still a lot of work to do to get it done.
-
Great start...what kind of wood are you using? I may some day attempt making a stock.
-
Andy, looks like you have the hard part done, now the fun can begin. Keep us posted on your progress.

The stock is made from 5 layers of 3/8 plywood. That allows me to do the inletting without needing a lot of tools or time.
I've used the method to make stocks for Crosman 760's, but this is the first springer I've done.
My dad wants me to build him a thumbhole stock (like I built for one of my 760's) for his Shadow 1000. The Baikal seemed like a good stepping stone to practice with before attempting a Gamo stock.
-
I built a stock for the Baikal before check the height of the comb before finishing I found on the first one the drop on the synthetic stock is a lot and I ended up adjusting the stock later,set the rifle in it and see how it lines up. Nice start I haven't tried plywood but I like laminating stock because you get rid of the grain memory so their is less chance of warping , also a lot of the fitting can be done during the glue up. Nice job so far I 'll be looking for the finished pictures when it's done Howie
-
The comb is a lot higher than on the standard stock. I made sure I could see in the scope correctly when getting the hight of the new stock set up.
-
That looks like it's going to be seriously sturdy! Have you ever considered, since you're laminating layers together, making hollows in the wood (perhaps filled with foam?) in order to lighten up the overall weight of the gun? Jeez, I envy your skills!
-
Can you be a bit more specific about the type and grade of plywood, glue, and laminating technique? Have thought about making myself a crossover stock, but hadn't considered a laminated stock. Can't wait to see your finished laminated stock! Any others to show off?
-
real nice start can't wait to see the finished product

The difference between marine plywood and exterier plywood is their are NO VOIDS in marine grade the glue is the same , I know I've worked on wood boats for years , one trick you can do is if you find any voids running across the ply is to fill them with thinned epoxy glue you can thin it down close to water thickness and it will still have full holding power , you could use talc power for thickening too. The plywood is an instering idea I've seen some carvings that were done with ply and they ended up real nice. You can get 5 ply or 7 ply a kind of shop grade. Howie
-
Glad you like it. I left the stock solid to help balance the gun.

I used 3/8" BC exterior grade yellow pine plywood. I would rather have used a hardwood plywood like birch, but I couldn't find it in 3/8" locally. 3/8" works out very well for inletting as the spring tube diameter is just a little wider than three layers of the plywood. I made a core of three layers fitting the action as best I could then added another layer on each side. I made the forearm extra deep to allow plenty of glue surface to attach the sides. Then I put a 50 grit belt in my stationary belt sander and a 50 grit sanding drum in the drill press and removed most of the wood that didn't look like a gun. A rasp, files, chisel, and palm sander also helped too! :)
I used good ol' Elmers wood glue that I've used for years. "It's stronger than the wood itself!"
-
OK. Here it is. I stained it with Cabott Ebony stain and finished with 2 coats of tung oil. I wasn't too sure if I was going to stain or just paint it and be done with it. I figured I stain it and if it turned out too ugly I could paint it later.
The trigger guard is a piece of 1/8" x 1/2" steel bar stock bent in the vice, polished and blued, and inlet into the stock. The rear action screw goes through the guard to keep the screw from pulling through the wood. The butt pad is from a Chinese B3 underlever.
Still need to put the rear sling mount stud in the stock.
So what do y'all think. Had I better get a can of bedliner? :)

Here's the thunbhole stock I did for one of my Crosman 760's. This one also has a 1760 barrel custom machined to fit by Mountain Air Customs.
-
The grey looks good, the lighter shade would be awesome in an olive green. I've tried stuff like that before, with less than encouraging results . . .
-
I'd be proud to have that stock on my MP512M, ya wanna make another one?? That looks so much better than what they come with. It's very unusual looking. Very custom. I like it.
Your 760 stock is sweet, too. Makes me want to restock my 760, 1377, and 2100. Then there's my B5-10.
-
I like it I re did the stock on my Crosman storm in ebony a couple months back and pictures did not do just est to it either. So I have a good idea what yours looks like . It breaks the stock up and gives it a rich look with out every thing having the same shade of color . The wood grain is much more pronounce IMO . Marvin
-
Really nice work. Hell no, don't paint it. It is a beauty.
-
looks good, my 2cents don't paint it.
-
It may not have turned out how you expected, but that doesn't mean it's not much better looking than plastic/bedliner would be! I think it looks good as is and the character of the wood is nifty. :-)
-
Thanks guys.

Here's another view....
