Today I was scraping in the sole of a straight edge. So I could get around it I had it loosely held in a vice on the end of my milling machine table - same as I usually do with parts that will fit there. I'm always careful not to over-clamp stuff when scraping because - you know - everythng bends. Just for kicks I clamped this straight edge up tight in the vice and took a print. Take a look at what happened!
Here it is just nipped in the vice. The straight edge rests on the two blocks and just held enough so it won't move. I rattle it in the jaws when closing them and stop just when it stops rattling.
Now look at the vice handle where I've pulled it up tight.Haven't turned the handle very far but look at the effect it's had on the straight edge:
Stuff is hard to hold for scraping sometimes, this is just a warning to think before you screw a part down hard or clamp it solid for scraping - you might be making life very difficult for yourself.
