« Part 18: Workbench Eve Part 19 of Roubo-Moxon Bench Build series no next part

Still waiting on my oil to entirely dry.

Meanwhile, I thought I would fix something that I knew would bug me all the time. My big honkin’ wooden vise jaw is too massive for the few inches of threading in the big wooden nut in the leg vise, and as a result the big wooden screw tilts downwards towards the jaw. See look: here in the very back of the leg you can see the nut:

The nut is actually not glued into the leg at all; it’s merely held in place by those blocks that are screwed into the leg. So anyway, you can see that there are only a few inches of thread, and I suppose that’s why the screw does not remain perfectly horizontal. So I had in mind to glue a handmade wooden washer in the front of the leg’s vise hole to give some support to the screw. My brilliant wife said, “Why do a whole washer? Why not just glue little bits on the bottom since that’s where the support is needed?” She gets it, folks!

So that’s what I did. First step, cut out some little wedges that fit in my screw’s thread and that are rounded to fit in the vise hole:

I decided to go with two wedges. I asked my wife to name this type of piece, since it was her idea, and she named it a sham. Works for me. I figured out the correct distance between the wedges, and with some creative weighting, I glued the two shams in place:

And voila! my big wooden screw definitely is receiving much more support and is much more horizontal when in use.

Looks very good. I like how you managed to find the wood screw. I’m still wanting to make my vise screw by hand. Like yourself, I’m stuck not wanting to plane my workbench top flat. Mine is about 20” wide 3” thick laminated red oak. It’s been a bugger.

I think your wife should make an entry in Wickipedia and get the credit for the “sham” it would be a shame if she didn’t. Your bench is drool worthy.
