bodgermatic, are you still looking for a hand crank bench grinder ?
I've got one you can have if you want to collect it, I'm in Norfolk 20 minutes away from Wisbech,
(I don't really have time to sort out postage)
the one I've got is a British made Nigara model no. 2.21 made in Manchester, it bolts down to your
bench or as I've got it fixed to a block of wood with block underneath so I just clamp it in the vice,
its got 1 geared as in not direct crank drive and has 2 little knurled brass screw for oiling the drive shafts,
it needs or could do with a .5mm shim to tighten up the end float and there is a little play in the shaft
at the stone end, the shaft is approx 8mm and it did have a inch or 11/4 inch stone on it but I don't
know where this is ( misplaced in shed swap) its got a 150 x 20mm stone on it now,
I don't use it or need it, its just gathering dust under my bench,
I think at one time I had a 9" stone on it,
so its free if you want to collect it.
