Like Mr. Roller said, I just clamped a bit of .125" stock in my lil X2 mill and milled the tab
For tennons .. formed the tab, then flipped it 'tab down' in the vise after cutting away the excess,,,then cleaned up\leveled the base thickness.. just working by TLAR
Since I had the mill, I just created a series of lengthwise pockets at the proper locations along the barrel.. these pockets were barely just deeper than the base thickness of the tennon stock.. I cut\fitted the tennon stock, to fit and gave the edges a slight changer ( very slight ) placed into position and the pocket edges punched to push in\over the tennon stock.. very solid fit and can be made as beefy or delicate as you feel like..On my Banded gun ( Uh build ) these were also used to fit the wooden rib and be invisible
Other than the small pins..
Now I know there will be the " I can do it faster by hand " gang.... But it honestly didn't take a whole lot longer.. once I worked out what I was doing, vs what I was thinking it would take??? And I have made them by cutting\fitting, folding\fitting and making nail loops ( ala
Homer Dangler )
