It's always nice having a metric and imperial set of tools. I've lived both sides of the pond so I've two sets of spanners, drills, hex keys etc but still can never find the one I want. Luckily hammers and vice grips are universalPlanapo wrote:Thanks guys for your further support!
Right Andrew, I will start with the simple approach first. Unfortunately the nut is screwed on quite tight, I think something like NU showed is needed.
But I do appreciate to learn a bit about metal work, so thanks for mentioning the "pin vise", elf. Do I get this right that these holes are drilled by hand with this "pin vise"? I had thought one would need a drill press. But I still can't figure how it is operated be hand to get the lots of rotation though... Maybe like the Brownie Scout's way of fire making with dry sticks? Doesn´t that give one blisters until the hole is done? (If you ever want to know how to knit socks or a jumper, feel free to ask me).
Nonetheless things are still getting a little more annoying: Just tried to screw off the broken base of that mounting block but none of our hex/Allen wrenches wanted to fit in these screw heads ...
Dang! All of these screws and threaded holes on that table seem to be non-metric!
Hope the local screw dealer has such exotic non-metric hex wrenches... last time I got ripped off there when buying whitworth threaded screws to fit in 1/4" or 3/8" threaded holes of camera gear..

Have you tried something as simple as grabbing the nut with a pair of pliers ?
Pin vices can be used for holding small drill bits and hand drilling by twirling it between your fingertips. In my experience works fine on soft wood but good luck trying to drill a hole in metal with it. You're better off with a Dremmel and some safety glasses.
Been there, done that -- more times than I want to think about!
