Precision V-blocks (32mm & 7") - any UK buying advice ?
Slight worry about the precision requirement - does John need more than a matching pair? It's easy to manufacture two almost identical V-blocks by grinding them together as a pair. So even a cheap pair of blocks should match accurately, and two blocks are usually all that's needed. V blocks don't have to be an exact dimension unless three or more are needed together. If that's the case, look at high end precision blocks, £££. It's the multiple precision part that's costly, rather than what they're made of. Much depends what they're for of course, but I avoid expensive tools for ordi...
