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
Good luck!
