Nice work indeed. I can never get a side mounted scope rail to hold zero. I'm refering to AK 47's etc.

OK, He got the rings in yesterday, but rail has not arrived yet. He's looking over the work, he's ancious for the rail to arrive so we can finish up the mount base. He said we will put a 36X B&L scope on this one.

Nice Work 44ultramag and AzizaVFR

Hopefully I will be able to get back on this scope rail project and use some of your ideas. I dont have any Millet scope clamps floating around and would have to buy a whole ring set probably about $26 plus shipping to the top of the world. Am going to dig in a couple smiths junk boxes for a clamp system when I get some time to look. Old top mount 22 scope bases might work you would have to file or mill off all the ring appendages above the actual rectangular part of the base. Then you could drill holes and tap "B" angle stock for attachment to side attachment on top for scope mount. Anyway thiese aren some great ideas and nice work.

STBE,

I did sand paper that area. For the front claw, I used a Dremmell tool to cut the wood on the INSIDE of the stock for the rear claw to clear.

I had to just reduce the top wood about 1/8 inch for the rear claw (width of the claw) but,does not require any real noticable change to stock.

Need that 12 inch long Weaver rail (continues series of slots)! The cat is ready to get this project done!

Notice he has his Burrs Signature Zee Rings.

CM-2 vs Ural mount differences

I was able to get this one unit cut. It will be verified by another member for fitment and use. Here are a couple of pictures showing the progress and difference between the CM-2 and Ural mounts.

First Position cutting. The mounting holes, Picatinny rail and length are established during this movement.


Second Position cutting. The relief for the loading area is made, the dovetail and receiver clearance was made during this position. When I started with the blank it was 1.6lbs. After this position, the weight was reduced to 6 oz. One thing I noticed in this pictures is the ripple pattern even with a very low feed rate. The handwheel is out of balance causing the powerfeed to speed up and slow down depending on the handle's position. That issue will be addressed.


Here are the CM-2 and Ural mounts together showing the differences. The Ural requires a greater depth between the dovetail and the bore centerline. Also, the clamping area has been extended 0.5".




I did acquire enough material to make some more of these. Unfortunately, I will be tearing down the work area in order to get everything moved starting the first of the month.

Looks like chatter to me - tall, relatively thin, unsupported wall being side-cut by the end mill.
Bead blast the finished workpiece and the machine marks will become virtually invisible.
Fixing the powerfeed handwheel stationary will only result in a consistent chatter pattern.
But, it will not eliminate the problem - lack of workpiece rigidity and insufficient support of the milled surface.

Right then, Made it out to the range today. Very first time to fire this CM-2. This design side-mount scope base seems to work OK (still ain't purdy like Randell's). The shot @ the top is from a cold barrel. It always seems to do this. The next 5 shots are in the group.

The scope base placed the bullet 1-1/4 inches to the right, and 4-1/2 inches low @ 50 yards. a set of + / - .005 inserts in the rear ring brought the group within 1/2 inch of dead center. Burris Signature Zee rings and the offset insert kit, gotta love it!

This rifle didn't like Wolf Match Extra. It really liked Eley Club XTRA though!

The cat seems pleased with the outcome.

The one mount I made did mount to the Ural, yet I think I had the measurements a little off, since I did not have one in my hands. The final height over the bore was a touch too high.

If I had one in my hands to measure, I would build a side mount to fit it with either a 10 or 20 MOA slope to the picatinny rail. Any takers in Southern Arizona?

AzizaVFR,

I am too far from you.......
I have Ural 1s and Ural 2s that I would be glad to leave with you if I were closer.
Your workmanship on the mounts in this thread looks great!
Hopefully there will be someone close to you with a Ural that will take your offer.

To everyone on the Forum, have a Happy and Healthy New Year!

Jerel
