Brass Rail to Wood Flange Conversion

Hi Terry,

OK, you've measured the contact area, but my other concern was with ease
of installation. I have a problem figuring out how  it will be to hold
those rods in place when you install the flanges. My other concern was
what if these rods get imbedded and then loose and rattle? I still think
it would have been easier to glue a piece of wood on the rail so you
wouldn't have to hold anything while installing the flanges. Let us know
how things turn out.

Okay guys, please help me understand here. 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?
