My Progress To Date

Attached are photos of my progress to date. The barrel pack is largely done. The pack consists of (7) Ruger 10-22 barrels, (1) Winchester barrel, (2) Sears barrels and (2) Springfield barrels. The barrels are retained using the locking wedge method developed by cutter. I made 2 extra barrels giving me a 0-9 and X & Y barrel.


The barrels are headspaced, chambered and lapped flush to the Rear Barrel Plate. Headspace measures between .044 and .045 (minimum headspace is .043). Every barrel is interchangable into any location and the headspace remaings in tolerance (.043 to .046).


The Front Bow is next up. The programs are loaded to cut a couple of different styles to see which one is most pleasing. I have ordered 5/16\" x 1/2\" x 5/32\" ball bearings and 5/16\" x 1/2\" x 5/16\" needle bearings to try in addition to a bronze bushing to see which one runs the smoothest.


I figure that I have a couple of years to go.

Great start Nitewatchman, good progress in a short time.

How does the locking wedge retainer work? I can\'t seem to find a post by cutter explaining this. Just looking for new ideas that come along the way. Thanks!

If you look just in front of the Rear Barrel Plate you will see a wedge between the barrels. The barrels are slotted to receive the wedge. There is a counterbored bolt hole in the Rear Barrel Plate that allows a 4-40 screw to draw the barrel tight to the Barrel Plate. The Barrel is turned to a straight tendon for a snug slip fit into the Barrel Plate not threaded. I machined my tendons to .400\" and cut the wedge slots .050\" deep x .190\" wide. The wedges are .1875\" thick.

The design allows the Barrels to be mass produced with the Wedge Slots and Extractor Slots to be cut in one setup and all Barrels are machined exactly alike. Assembly is very easy and sure and timing of the extractor slots in precise and sure.

Cutter receives all the credit. Look in the Machining Section under Interchangable Barrels.

Thanks for taking the time to explain the wedge system to me. I can\'t wait to see your finished gun. Thanks again!

Me too!

Been a long time since I have posted any progress.


In machining parts for the gun it sometimes appears that when I finish I will have two. One made from brass and one from wood. Below are wooden prototypes for the Elevating Handwheel. One is made from Lignum Vitae and the other from Celin. These were machined using a 3/8\" straight carbide end mill and 32 pitch home made thread mill. The pieces are straight out of the mill with no finishing or sanding.


The brass piece turned out identical but not nearly as attractive.

Very nice Gary !
I\'v always liked the grain.
