Quick release or not? Opinions and reasons why wanted.
I think it depends on where you are going to use it. I don't think quick release would be that useful on a face vice but it could be cool for a tail vise.
I guess it also depends on how you are going to use it. I use a leg vise for working verticals and edges. It is the polar opposite of a quick release vise
I use a tail vise for working faces. And I use them both for odd shape clamping. I can honestly say I have never really wished they were quick release. But I put lots of effort into the bench itself. My dog holes are ~1.5" from the front of the bench and are spaced a little over 3" away from each other. I have a dog in each hole. I never have very far to go:
Yes Mike it is awesome . This is from benchcrafted.com. It isn't cheap. But if you price out the allthread, nuts, handles, guide bars etc individually there really isn't much markup.
A little over a year ago I stuck a chisel in my hand while doing something I shouldn't be doing: holding the workpiece with my hand and doing just a light trim. The deductible and copay for my insurance cost me more than the vises. It was my motivation to improve my work holding/workbench.
I found a deal on the hardware from a guy that bought the package and didn't get around to installing it. But if you like this sort of setup you can do it much cheaper and still do it well. A traditional tail vise can be made in the shop and only requires a screw and nut. A leg vise is similar. The hardware that benchcrafted sells is way overkill. But it operates very smoothly and it is a pleasure to use. My workbench is my favorite tool
