Hello there!
I’m new here and a relative beginner to woodworking. I just finished building my first bench, nothing crazy, it’s small (48” x 20” footprint), nor do I have room to build any bigger, but I saw this as an experiment to learn.

I also installed Lee Valley’s basic front vise. The install was fine, and everything operates as intended. I have yet to add the taper (Veritas manual calls for a 2 degree taper on the clamping face of the front jaw), but it got me thinking.

I was just trying to grip some wood and as predicted, SLIGHT gap/racking occurred vertically (which I assume is remedied by this 2 degree taper). I intend to add leather as a liner to the front jaw, and I was wondering if the taper would be unnecessary if only applied to the top half (or only above the main vise screw)?

The front jaw is 5” high, so if my math is correct (and it may not be), a 2 degree taper would mean adding 2/16 – 3/16 material at the top to create the same effect (1/8 piece of suede/leather should do the trick)

So, can you use a vise liner in lieu of 2 degree angle?
Thanks!

Dave

Your math is right, I get 11/64. That little material is pretty easy to take off a wooden piece with a hand plane, though I guess it takes some practice to be able to do it and keep the tapered face flat. I can’t say anything about whether the liner would work instead.

Should have mentioned I don’t even own a hand plane yet. YET. ;) It’s coming eventually. The cheap comes out expensive in my history, so I’d rather wait for a better version than contend with a lower quality one (e.g., Veritas, as Lee Valley is near where I live).

I had some craft paper bags and and put a bunch in between the vise and wood being held and it didn’t rack vertically. So I suppose a little bit of material – which also acts as a gripper and will protect the piece from being marred – will be a suitable alternative until I can properly plane the 2 degree taper.

If you have a planer, you could shim (appropriate thickness) the bottom of one edge of the jaw to create the 11/64” taper.

Have your say...
