Hey @JoeN, so the current one has some issues and I’m planning on giving it some tlc as well. I was thinking of a smaller, quick-release vise in addition to the current one, not instead of.
Part of the reason is selfish… I think it would be fun to make a vise from scratch.
Another part of the reason is that due to the way the current one is installed, it has some issues. It gets out of alignment very easily along both axes of the plane of its face. To get it back into left-right alignment (unless you want to manually adjust both screws, which defeats the whole point of it being such a fancy vise) means taking off the chain plate, loosening the set screws, realigning, and putting it back together again. I wind up doing this pretty much at the start of every session I’m on the table. Some of this could probably be fixed with a bicycle chain tensioner (as recommended by Veritas in their user manual for the vise), and I’d like to try, but I’m not sure. It looks like the backs of the screws have a bit too much relief / freeplay, which causes the up-down racking. I was going to see if I could attach some guides to the bottom of the table as well, but didn’t think it work mentioning.
Finally, the twin-screw Veritas vise has no quick release feature. Which means it’s really great for holding a big piece of wood for a long time quite firmly, but if I need to have a board face showing, then realize I need it to hold my sharpening stone, then need to switch to end grain, then have to adjust it so I can saw off a piece with minimal chatter, etc, it gets to be a bit of a pain.
