I've seen a slotted type wrench used to install dove tail rings, a taped up Cresent wrench, and a "scope bar" - (rod, pipe, dowel, whatever). If a scope bar is used, I assume it's ok to tighten it down in the ring and then turn the ring into the base? I'm sure some has used their scope but I don't think I'll do that to my new scope! Thanks.
