This vice is nearing completion. This morning I clamped a piece of round bar in it and was pleased to see that the jaws are parallel and it clamps evenly.
But, I did learn some useful lessons today also. I wouldn't class myself as inexperienced but most of my engineering work has been with steel, cast iron and aluminium. This morning I had to machine the bronze nut for the leadscrew on my lathe. After a couple of dig-ins using my usual tool I thought that I would grind a new one with no top rake, well, it's chalk and cheese! After that I backed off the point of a drill and it went through with no grabbing. I have always been too lazy to grind separate tools, all I can say is, "what an idiot I am!"
The second lesson was not to forget to lock the slides on the milling machine if I want to prevent the cutter from digging in.
All in all a couple of useful lessons, I knew about it but had just been in too much of a hurry.
