I guess I'm a curmudgeon. Whatever. If it is in fashion I don't like it. I don't set out to dislike the bench appliance or vise, in fact I'm usually a fairly early adapter with high hopes that it will be the end all of work bench aids. But it is kinda like the country song line about looking for love in all the wrong places. Usually no joy.
Leg vises and wagon vises are the "it" vises today, almost every new bench build has one or both. As I've posted before: BTDT and didn't like the T-Shirt. I've tried using leg vises on benches other than mine thinking maybe I did a poor install, not the case at least on the ones I've tried. Maybe others have better luck but I find leg vises fussy and slow to use and frankly they hold no better than my English QR metal vise. Basically no working advantage and a hell of a lot more work to install, kinda lose lose. I must add: Leg vises can be pretty and I guess sexy in a bench vise way, where my QR vise is kinda like granny's underwear, not very attractive but it sure is functional.
Wagon vises, what can I say other than I just do not find there is a need for end vises. There are other and better ways to hold work and the wagon vise is also a PITA to install maybe not as bad as a classic tail vise but still....Again BTDT, same shitty T-Shirt.
The latest is the Moxon vise. I had to try one and this time I was late to the party. I had high hopes for it and I could see some real possibilities for the Moxon but in practice not so good. It does what it was designed to do and that is to hold wide boards. It clamps down tight but....there is that damn but that always pops up...at least on my bench it vibrates when sawing. I tried it on both benches same result, tried with different holdfasts, both the regular whack 'em kind and the LV screw down ones, same result. Bottom line: The Moxon is stored under the bench to maybe be retrieved if I'm doing dovetails on a wide case....maybe.
I'm sure there are folks out there that have used other ways of holding work on their benches and still find a leg vise the best option as I sure there are folks that can not do without an end vise, I glad you have found what works for you. For the folks just starting on their first bench build, remember just because it is in fashion and everyones building a bench with leg vises and/or wagon vises they may not be the best option.
