Terry,
Usually, those jack stop rails are mounted with threaded rods that have =
a right hand and a left hand thread on them. I've always been able to =
just keep screwing until the end, (in the hammer rail), exits. Usually =
you have to do them in tandem so that they don't bind and warp the =
rail(s).
Your other option would be to put a "butt felt" on each jack at the =
location of contact with the rail. Pretty simple really. Hemostats, hot =
hide glue and a bunch of butt felts. Take all of the bridle straps loose =
so that you have better access.
