During our session w Matt Cianci, one of our carpenters uncovered a wooden saw vise that caught my attention. I probably have walked by this thing a number of times in the past 20 years, but last week was ready to see it.
I’m sure many are used to this sort of device; I had never used one before. I had a borrowed Disston vise that I was never happy with; chattering and vibrating were common with it.
This one’s got mortise & tenon joints, I know how to cut them. So I decided I’d copy it. I think of it as 2 frames, the “front” short frame and the “rear” longer frame. That section is repaired on this original. Other than a pieced section added to restore the rear feet, the work is pretty average. Which means it’s not done very well. The cross-pieces are just scabbed on with nails & screws.
The original work is nicely joined. Looks like ring-porous hardwood that’s not oak. Ash or chestnut, and I vote for ash.
The front frame has the turned roller in it, that is mounted off-center. So when you twist it, the roller bears against the pieces mounted inside the rear frame. and the front frame pivots on those tenons between the frames. Presto – the jaws pinch tight.
There’s just enough play in the mortise in the front frame so it can move. So simple. I’m making mine mostly from ash, but I came up short one piece. So one rear leg will be red oak.
This requires tight joinery; good shoulders. No loose-fitting joints here. No twisting or wracking either. Good practice for me.
I bet someone with fewer than 1.000 visitors a day could make this in short order. I fussed & fiddled with it today. Hope to mostly wrap it up tomorrow.
Many might want to ask “what are the dimensions?” or some such thing. Others will know better – I don’t work w drawings for the most part, certainly not when I have the object in front of me. The uprights are from 1 1/4″ x 1 1/2″ stock. there is 15″ between the uprights. The jaws are about 2 1/2″ high. I think. I forget.
In the photo just above you can see I have to plane the upright down in its thickness to match the slightly thinner jaw stock.
