Thanks for the input have not checked the metal on the web yet. May have to wait for the weekend. I am off right now and shooting that SUHL which is another story. Found out that there is a Grangers here where I live. MRmosin I asked on open forum about drill press and light metal work was pointed real quick to mills. If I had a mill I am afraid your suggestion of going into business would be just too much for me not to try. With all the government help I know we could make it in the new socialist world. Heck might even be able to sell these mounts back at the USSR or whatever it is now!!! But then those smart Russians may have sold off all their beat up old bolt 22's back at us!! Oh well.

U44mag yes filing dove tails is probably a lost art those folks have all passed on or got government grants to study to become TSA agents or some such. Umm!!,..... back on subject. I may look into a machine shop or two and ask about having them make me a dovetail or two or three as there are several friends that might go for this if it works. I could get a good length of square tubong and have them dovetail out the whole length. I will let you'all know. I guess you might could also incorporate the the Rusian's sight's DT screws to make a homemade work but then you have to contend with the dablanged Russian thread pitch and metric dimensions. I hate that! Bad idea! STBE

After looking through this thread and trying to make a side mount as simple as possible, here is what I put into the computer I used the rear aperture sight as a basis for the clamping system. I wanted to make it where it has an absolute point of reference, the top dovetail, when removed and installed. The height will not change through repeated installations.



It can be made by milling one piece of aluminum. The clamping dovetails could be made from the material cut away from the main piece. I have uploaded a PDF of same image above to the following link:

http://www.keepandshare.com/doc/view...d=1174795&da=y

If I was not backlogged in making single shot adapters, plus planning on moving from California to Arizona, I could make one of these. I will need to buy a block of aluminum to try making it. I have all the needed cutters and drill bits.

Maybe this is a dumb question, but what is the actual size of the side dovetail in mm?

Are you milling the piece out of a block of aluminum? Have any idea what 1 to several of these would cost per unit? STBE

Lonepine, the dovetail is 11mm with 60 degree angles. I tried to make it to the metal supply store today while taking my wife to her evening classes. I did not make it there in time with traffic. More than likely it will start with 2lbs chunks, then be cut down to size. If I get some time this weekend, I will go pick up a couple of blocks and see what can be made. The drawing above has been updated to add a Picatinny rail.

Excellent work AzizaVFR - good thinking ... establishing a datum line.

With your drawing, a machine shop should be able to fabricate your mount without too much difficulty.

I had a chance to get some progress laying out the blank and cut the top. Unfortunately, I am waiting on my 45 degree dovetail cutter to get the underside of the Picatinny rail cut. The mounting holes have been drilled and countersunk for the socket head cap screws.





More to come...

Is this going to work on the Ural too?

I am not sure if that design would work with the Ural. If the dovetail is in a very similar place on the side of the receiver, it should work. This is as far as I could get with it. Due to the lack of the dovetail cutter for the rail, I could not mount a set of rings to the rail. It did take more time than I thought to cut this out, due to the amount of material removed. Here are some more pictures.









There were many changes and modification needed to make it fit, especially around the bolt handle and the loading/ejection port. I even made the retaining nuts for the bottom. They were not included in any picture.

Randall,

A true piece of art, well done!

You are keeping track of your hours on this yes? As it's a 'one-off' @ this stage; I'm interested to know how long it takes to make one. Of course a programed CNC could turn them out very fast!

Regards, ultramag44

Taking into account work and wife interruptions, it about six hours of machine time. This is using a manual mini-mill with no power feeds, taking a maximum of a 0.030" per pass to keep from breaking the plastic drive gears within the Harbor Freight mill. To cut this piece requires three cutting positions. One for the top, another for doing the relief cuts and the dovetail, and third for pockets for the clamps. A second piece of material is used to make the clamps.

The clearance between the mount and the receiver is actually too tight. I think I have less than 0.005" clearance once it is in place. The other issues is the thickness of the clamping nuts. I may have to make them out of something a little stronger than aluminum because they need to be very thin to clear the stock and have sufficient strength to hold a target scope and rings. They are the weakest link in the design.

Hi Randall,

Mine is done, w/ the exception of the Weaver slot rail. I just ordered this part.

Ignore the discription that says "contoured for popular actions" I emailed them. They say the bottom is flat.
http://www.combathunting.com/product...t=6375&group=*

I'll drill it for 4 mount screws.

Regards, ultramag44

Here's some sneak peek pics. Waiting for the fill-length Weaver rail to come in. The two #28 Weaver bases ARE NOT going to be mounted there. Just there for pics. The line scribed in top pf plate is exact centerline of bolt

I'll cut the slot above the action opening after I have rail placed.

Ain't Purrrrrrrrdy like Randell's. But, I'm using files, hacksaw, simple drill press, any questions then?
