Mine is just cut and welded and plated on the inside. Works fine BUT, I think the best (or at least better) would be to cut down to the center of the rail, then along the rail perhaps 8 inches then down out the bottom, sort of a half a swastika sorta cut. this would give way more bonding/welding surface than just a straight vertical cut like mine. If you want (and you're patient) I can take some pics of mine but it may take awhile. I'm working long hours these days and, unless it rains, won't have time for awhile.
