I'm understanding both = Ron and Marcel to suggest that the butt flange in the picture below does = not have sufficient contact with the action rail. Marcel goes further to = suggest, that because of a lack of contact, the metal rods will imbed = themselves into the flange and rail and the flange screws will = continually loosen. This system has quite a bit of contact between the flange and action = rail. The two entire rectangular areas (about 12mm x 5mm each) of the = flange above the flange screw and below the screw are in intimate = contact with the action rail. Plus it also has the limited surface area = of the wires. That's not enough? The only way that would not suffice is if the flange is going to bend a = fair bit under the screw (because of a lack of support there) - but the = screw head extends all the way to the two rectangular areas above and = below the screw that are in contact with the rail. And of course the = metal wires are there also. Seems to me this should be very stable. Please help me understand. Am I missing something? Thanks for all your thoughts and input.

That won't last. You need contact area. Either build up=20 > the rail to fit the flange, or change flanges. >=20 > Ron N ----- Original Message -----=20 I have to jump in on this one. I think that this setup is due to fail. = It seems to me that it won't take long for the rods to dimple in the = flange and the rail. Eventually, I can see the flanges moving forward on = the rail after a few years tightening of the flange screws. Have you thought about gluing a piece of maple on the rail to fit the = flange, or, glue a strip in the aligned set of flanges and then = recutting and redrill. I think this would have given you a lot bigger = contact surface than just the 2 steel dowels. A piece of sandpaper glued = to the rail would have then prevented the moving around (same as in = older grands' hammer rails). Just as usual my humble opinion.
