I am about to install my Veritas Twin-Screw vise. I’ve got a careful plan, have read the installation instructions twice (at least) so am hoping to start this weekend (assuming wife doesn’t have other plans).
One open question is that Veritas says to mill the outer (moving) chop so that is asymmetric. In other words, plane it so that the top is slightly thicker than the bottom. Here’s there picture:
The goal is that “This will ensure that pieces clamped in the vise will always be gripped at the top of the jaws.”
I don’t have a problem with this, but it seems like a little extreme. 7/16” on a chop that is 7 3/4” high is about 3 degrees. Doesn’t sound like much, but it seems like in most cases, only the top couple of inches of the chop would actually be in contact with the piece being held. And that part in contact would be ABOVE the actual screws of the vise. It just sounds weird.
My inclination is to make the asymmetry much less aggressive. Perhaps 1/8” instead.
Thoughts? Any of those who have installed and used the Twin-Screw vise have feedback?
