Thread: Dawn No.7 Quick Release

Greetings All, I need some help with a picture if possible from some body that has a Dawn No. 7 woodworking vice with quick release, I rescued this vice from some one that was going to throw it away some time ago, you see the quick release has a part missing, and is the actual part that screws underneath to hold the flat bar that holds the nut against the screw, and also what sort of spring is used to return the actuating lever to its lock? position, is it a coil type spring? I think I used a clock wind up spring as a poor excuse for a fix up some time ago, the problem is when I try to clamp something tight the nut slips out of the screw and looses its grip, I had a small bracket holding it in place but it is not working very well, I included some pics, sorry they are a bit blurry, I want to see if I can make the missing part, I'll post this in the woodworking forum as well, any advise will be greatly appreciated.
Richard.
