Jim,
Several others have looked for a band or such to prevent ruining of stocks. So lets use you as a guinea pig on this with the idea it can help others.
Found the parts in the mail after hours yesterday. The screw has 1/4 28 threads. The 2 photos of the band show that loose it spreads out considerably. In the tool makers vice the inside measurement is .708 when the legs are more or less parallel. Assuming that the band will live with plus or minus .032 in barrel diameter it will go any where from 10 inches to 17 inches from the end of the receiver, with 12.5 being the sweet spot at .708 inches.
The firs thing I want to do is make a mock up and see if this is going to fit in the stock at the lengths mentioned. I have a photo of my dad's original 98 Krag with marks at 10, 12.5 and
17 inches. I have some 1/4 X 1/2 aluminum rectangle stock, if I can find it I will turn the 2 catches and measure how much it stands off the barrel. If there is room we will proceed to proceed.
Could use some help here, what say the rest, are we barking up a good tree?
Jim,
Added thought.
I went back and looked at you posted photo of your stock, can you do what I did? Put a couple of pieces of masking tape on the stock they do not have to be really stuck down and mark 10 and 12 inches with a marker on the tape. Lets see how thick your stock is in that neighborhood.
