Poor Man's 2100W

[Ronno6]

I had discovered some time ago that the buttstock from the Crosman 622 mated fairly nicely with the receivers on the 2100/2200-Model 1 Crosman rifles. Dennis Baker sold off a bunch of 622 stocks on the bay, and  I purchased several.
I occasionally run across a good deal on one of those with the buttstock broken or missing.
There are some tricks in mating the stocks to the receivers.
First, the 622 stocks have a concave groove in the lower part of the tang which located it onto the 622 receiver.  Photo 1
The stock on the right is a Model 1 stock showing the square boss which locates the stock onto the rear of the receiver.
The 622 stock is modified either by filling the concave groove with a dowel rod section (picture 3), or by trimming off the tang 1/4".(Picture 2.)
While trimming the tang shortens the LOP a tad, the resulting tang profile is much closer to that of the receiver.
 In either case I fashion a thin slab of wood to fit snugly into the receiver end, which I then glue to the tang.
Rather than fashion a yoke-style mounting to mimic the original plastic stocks, I fashion a mounting plate for inside the receiver
and attach via a long 5/16-18 bolt purchased from McMaster Carr.
The plate is made from 1/8 x 1 1/4" steel flat bar and shaped on a bench grinder.

I may work on a jig to machine the stock tang to mimic the Model1 stock, as that would be a bit easier.
The results aren't too bad for first attempts..........

Now, I GOTTA figure out how to make thise forearms/pump handles....

Nice work. I just saw a model 1 on the eBay auctions the other day. almost went for it. Wish I could afford a few hundred right now.

[Ronno6]

 Yup.
It's gonna go for a pile.....See my thread in the Vintage section.

This one was in decent shape and up to like $351 with a week to go at the time. Friday I think? A special edition NOS with a medallion in the butt stock. 75th anniversary rifle.

Good conversation on this very gun here:

Nice job fitting those stocks.
Looks a lot better than most factory work that I've seen....LOL

I wanted to buy a few of those 622 stocks but there was no picking.
You received what they sent you so that was a deal killer for me.
As I recall they were around $20 a pop.

Making a forearm should be fairly straight forward.
Instead of attaching it to the link with pins or screws, I glue them with construction adhesive.
Can get them perfectly aligned and they won't get loose or come apart.
Here's one fitted to a steroid Benjamin 312 I bought from Avator.

[Ronno6]

They were $10.00 + shipping, but the shipping got pretty reasonable the more i bought at a time.

Looking at a Model 1 forearm, there is a slot routed into the deepest recess of the wood, where the pump linkage nests.
That would require a router bit with about a plunge depth of 1-3/4" or so.
That slot is not flat the entire length but rather, slopes upward to match the curve of the linkage.
I don't know how critical that is...........


I could make in 2 halves, then glue together, but i don't know how noticeable that would be.

[Tack Driver 10]

I don't set the wood as deep in the tube as a stock pump arm.
No need to and it scuffs the sides of the tube so less really is more here.

I use 4 flute 1/4" carbide ends mills in the router to cut the slot.
Can be had up to 6" long if you choose and fairly reasonably priced..

Step rout in 2" sections and finish the taper with a chisel.

Use a 3/4" Diameter Round Nose Router Bit to cut the tube channel.

[Ronno6]

I had the 3/4" dia. cutter figgered out.
interesting thought on the bottom groove.
I've been contemplating a U-channel fixture into which the forearm sits.
It would have sides which rise up, elevating the router to effect the decrease in depth of the bottom groove.
I'm more into machine process as opposed to hand work. Quicker and more repeatable in volume.

OK, then maybe this is what you need....LOL
Makes a great Christmas gift.

Ahhhhh......THAT'S what's in that box under the Christmas tree.....

Boyd's has some laminate stocks that resemble the 2100's:

A matching laminate forearm would look fantastic

Darn it, I was hoping it was going to be a surprise.
I guess the cat's out of the bag now.

Contemplating a router setup with a sled which will rise to a prescribed profile.......

[Ronno6]

I think I have the fixturing and processes reasonably mastered for making the wood forearms for 2200/2100/766.
I have the process for fitting the 622 buttstock to the receivers of the pumpers.
Fitment looks pretty good.
What I HAVEN'T figured out is how to make the forearms I make LOOK like they belong with the Crosman finished stocks.
Their process must be a one-step spray, stain and finish. the tint is always so even...

I know this is a bit of a double post with one in the woodworkers  thread, but it reaches Crosman enthusiasts..........

I've liked the idea of wood on my 2100 for a while now, but the plastic parts are holding me back.
To me it just doesn't feel right to put a nice wood stock on a gun that still has a bunch of cheap plastic parts.

If I could replace all the plastic parts with metal ( the front sight is fine ) I'd put some wood on mine in a heartbeat.

Nice work fitting those 622 stocks BTW.

[Ronno6]

The plastic clamshells/barrel bands can be replaced w/metal barrel bands ala 766 or 2200.
Then the forearm would be more rounded at the front akin to the Model 1 shape.
Other than the barrel bands having cutouts for retaining the old style clamshells,
the remaining issue, if even an issue, it the end fitting of the pump tube.
The Model 1 had an extended knurled knob on the front end. Really gave it a finished look.
I'd have to machine one and figger out how to attach to the square end of the 2100 part.

Sounds like a lotta work...........

Ron, it looks Really NICE!

I was thinking just the barrel band itself and no end cap.
But theres still the plastic parts on the inside.

I guess for me wood on a 2100 just isn't going to happen.
