Swiss-

Bedding looks really nice after clean up. The impression of the bedding ridges in the Acraglas looks very detailed. Iíve been using Marine-Tex gray on the last few and it is a bit thicker and looks to have a shorter work time. Just used the last bit of it on my project and after seeing your write up, ordered Acraglas to try on the next one.

Let us know how that contour duplicator works out. Looked at one a while back but didnít have anything at the time to use it on. Looks like just the thing to get the lines you want from the CM2 stock. My hatís off to you working in wood since you only get one shot. You can take it away, but itís hard to but back if you take away too much. Thatís why I like working in carbon fiber- sand it off, add more on, its pretty strait forward. Well, sort of...

Really like the brass lamp nuts to use as fittings for the action screws- might have to give that a try. As for keeping the screw holes nice and neat, I use hobby shop brass tubing of various sizes to make nice clean linings.

As for the PVA releasing agent, it worked well. Gave it two coats just to make sure, but on the final fitting before bedding, saw a spot that looked bare. As an experiment, used a bit of the ole paste wax as insurance and also to see if the two could be used together. Initial fear was that the solvent in the paste wax would dissolve the PVA releasing agent. Happy to say it didnít, or at least didnít appear to. I will know later this morning when the receiver gets pulled from the bedding. Fingers crossed.

At a snails pace

But have made some progress, I am back too work @ my full time job, fishing and
home projects have kicked in for me....but that's OK
Gives me time too think
Have made the frnt. half of the magazine guide.


With a 10 rnd. mag. and the guide will be counter sunk in the stock....I think pretty
deep so I can catch the mag. unlock doodad.

I am thinking the trigger guard, mag guide, will be fabricated in a three piece deal and will be a one piece assembly when done, and am going to try and make the guard assembly cover the two receiver bolts too hide them.

Have the frnt. of the stock shaped pretty good for now.


Today I am getting the but plate in-place, and am fallowing my CM-2 stock to
get the right cast in the stock.


Getting it as close as I can too my CM-2 stock, that stock fits me very well.
There has sure been allot of measuring involved so far and no big flub ups so
far.
As you can see in the but plate pic. allot of wood has too come off.

Had some wood dust & shaving action

Ya I did some work on my stock today.
Went for some easy stuff today like the comb area and the top of the but stock.


Here is my CM-2 stock as my guide.


My new BB stock setting up the cheek pad.
The Morgan butt pad plate will dictate the shape of the stock.


So far so good, CM-2 in back ground.


This stock should look pretty nice when done.
A little rubbing alcohol, the growth rings run the length of the stock on this side.


So far no hammer thrown across the garage yet....
Next will start on the pistol grip area and a lot of hand wringing has
happened but will all come together.

Can't seem to find this from searches:

-what is (was, I guess now) the approximate weight of the non-adjustable 7-2 trigger?

-what is yours now? And I guess what kind of weight are you 'shooting for'? (yeah OK that was bad)

My trigger pull was just under 2lbs when I bough it new from the LGS.
All BB 7-2 triggers are adjustable if ya know how too do it, like down too 3 oz or up to 3 lbs.
Mine has a 1lb pull now, the BB 7-2 has a two stage trigger.

Well since I am here I have done some more wood work yesterday and today.
Worked on the pistol grip.


Starting too look like a target rifle.


Lots of work.

I worked on the other side.

I had one side left too work on.
Allot of wood too remove.


So I got out the power tools.

The 4" grinder worked very well then the belt sander.
Now I would not recommend using these power tools on wood unless ya know
what your doing, it is very easy too remove too much wood or leave deep scratch
in the wood.
But I use too work @ a factory that made commercial food grade machines for 10
years and used these power tool @ times for metal fabricating parts and what not.
So ya I have a good feel for how too use them.


Layer by layer.


Just about done using power tools and will have too block sand the rest.


Very happy so far

Well I have made two trips too the range too test things out, the stock is far enough along.
Tried the rifle with Iron sights.

Total failure I tell ya...was bummed out.
So did some thinking and removed the 1" bedding on the first part of the barrel.
This has happened when I did the Boyd's stock also.
I installed my full length scope rail back on the rifle and got two scope ready too
use, used a BSA 4-16x50MM AO scope and a Clearidge 3-9X32MM AO scope for a
back up scope.
Things went really well for a bit then had some wild flyers then they would go away.
So I installed the Clearidge scope.

Things did improve but still had some flyers, did shoot some targets @ 25 yards
in the RFC fun match's.

The rifle did shoot pretty darn good until the last row of gophers.
So I did some 5 shot group shooting @ 25 yards.

Over all not too bad but I think it could do better I also had my CM-2 with
me too get a feel of things.
The CM-2 shot darn good and did notice that the ammo was a little loose
for the CM-2 rifle also.
Here is the CM-2 target.

I have some more Ideas too try before I have the BB re-barreled.
But the trigger feels very good & will do a little more adjusting on that like
I don't like all the slack in the 1st stage.
The stock feels very nice and there is a lot more refining work too do.

Swiss--The stock looks great! That looks like a LOT of work. It's too bad there are few, if any, commercial wood stock options for the 7-2's. But, if you have the skill set that you certainly have, you can just roll your own.

I couldn't help but notice you may be considering a rebarrel. Those groups you posted really don't look that bad, though... I'm still waiting to see what RFC'er "Ziabeam" comes up with regarding rebarreling. He has not had a follow-up post on that particular project for some time now, I have been on the lookout for it.
Those trigger mods Z did were pretty cool as well.

Anyway, keep us posted on your stock project, I really enjoy following your work on the 7-2. I shot mine in a CMP style Sporter match last week, and also used it yesterday in a "Woods Walk" silhouette competition. Did OK in the CMP Sporter match (584/600) but sucked in the WW (40/50, all offhand shooting). I was thinking the factory "Russian fence post" stock is really not that ideal for offhand shooting (poor cheek weld, the "grip" area feels awkward to me as well) and I kept thinking I wish it "fit" me better. Unfortunately, my woodworking skills are sadly lacking

Swiss, I have the stock Izhmash rail on my 7-2, and using a Weaver "quad lock" extension ring set with a Leupold 3-9 EFR scope. Eye relief is OK with this set-up (see pic), cheek weld not so much. I need a taller cheekpiece, might try one that velcros or laces on.

Thanks Triggershoe
Here is my scope mount.


Made by D-machine, now when I bough it D-machine had the option of just the two
back screws or one extra one to screw too the front of the receiver and that is what
I went with, D-machine said the only two screw should work fine because his
full scope base is very strong.
So I went with the three and had a local gun smith drill and tap my BB front receiver.
I am just kind of back tracking too see if I self induced my horizontal flyer deal.
Maybe there is a reason that Izhmash didn't put a full length scope rail on in the first
place.
Now my BB doesn't like the barrel bedded like this.

And I have 5 .22 rifles bedded this way and shoot just fine.
So I have removed the barrel bedding pad and barrel is free floated just like when
I bough it.
So that tells me that the barrel and the receiver relationship is touchy on my BB.
My next move will be too remove the front receiver screw from my full length scope
rail on my next range test, and may even shim the back of the rail so the front
rail is free floated from the receiver also.
Ya I am nit picking too get rid of the horizontal wild flyers.
And was just one range test.
Maybe buy a new air rifle scope, if ya think about it when ya cycle the toggle it is a horizontal induced jolt.
It still could be my barrel glued in sleeve deal, but a re-barrel job it might be down the road.
Thanks Triggershoe for the new stock comments so far it is coming a long way better then I thought so far...

Re the D-Machine rail, that's the way I would have done it as well... Just makes sense to better secure the rail with that third screw on the front receiver ring. Is DM still making these rails? I have not seen any posts from him in quite some time. I still may decide to do a rail on mine, but it's really pretty good as is with my Weaver/Leupold EFR set-up, I just need to address the cheek weld situation.

Re the flyers, I guess it COULD be that goofy mounting sleeve that Izhmash used on these rifles. NO idea why they did it that way. I know mine is not glued in 100% because of oil seepage from the front receiver ring at the barrel/receiver juncture.

Keep up the good work on the stock, I'm sure you'll end up where you want it to be when finished
