Made this bench with end vise a few years ago. Have made a few tweaks and am very pleased with it.
It opens almost 4 feet and is very solid there
The jaws have inserts in French cleats with magnets
Plenty of space between the bars for dovetailing
Leather faces on the inserts
Can easily hold and plane stock 6 feet long
No handle on the end to catch me in the underwear so I can stand close and plane better
Lots of clamping force with fine control
No racking at all
Quick opening and closing
Quick adjustment for work that is slightly tapered left or right
