Hi, all. I have a Hansen string cutter and also a rounder. They are the original style Frank made, and have a base with drilled holes which you then bolt down onto...whatever...I bolted them onto a board and then would clamp the whole unit to a work table. (I see that the new ones have a built-in clamp). It also has the original style of locknuts (not the wingnuts). For me personally, I think the old style is much superior because you can REALLY tighten it down rather than just finger-tighten,
