RE: Unsure of how much weight for grip machines
Well my dad's a welder (and a damn good one with over 20 years experience) so could make an exact replica if I asked him to.
I was thinking of the grip handle (2 metal plate type things for the Telegraph Key, or 2 handles for the Handshaker) welded to some squared tubing which will go over a pivot point/hinge and will extend to the plate loading part.

I've got about 60kg's worth of ordinary plates that I've stashed round a friend's house, but would rather use Oly plates.
