I got some time in the shop tonight and was able to get the sliding board jack made and installed.
To make the V-groove at the bottom, I first made two cuts down the center with a rip panel saw. Then I cut a 45-deg kerf from the front / back that met those first two cuts in the middle. Finally, I chopped out the middle section and pared it flat with a 1/4” chisel and cleaned up the slopes with a paring chisel.
Here’s a picture after the first 45-deg cut:
After the second 45-deg cut:
Test fitting the board jack before shaping it and boring the rows of offset holes:
I don’t have a bowsaw yet. So, to cut the curves on the sides, I first made a series of cuts down the side with a crosscut panel saw that stopped at different points in the arc. After the majority of the waste was cut out, I cleaned it up with a paring chisel (bevel-down), followed by a spokeshave, and finally a card scraper.
Here’s the completed board jack installed on it’s track:

Finally a picture with wood chips and shavings all over the floor. Oh, and a nice bench too!

Nice looking bench. What does the top part of the board jack fit into? I assume ther is some play there for installation.

Thanks, Dave! lol
Yeah, I kept sweeping the floor before I’d take new pictures for my blog. :) But, it’s been raining lately, so I haven’t been able to dispose of the shaving in my burn barrel for about a week. So, this is the pile that’s hiding in the corner out of sight of all my last few blog pictures…

RG, I cut a groove in the bottom of the bench top that the “tongue” of the board jack’s rabbet slides into. The trench is 3/4” wide by 1” deep. Here’s a picture of it before I flipped the bench onto its feet.
I chopped the trench out about 1/8” deep to establish the start of the mortise walls. Then, I used a brace and 3/4” auger bit to drill out the majority of the waste and finally cleaned it up with a wide paring chisel and mortise chisel.

Cool thanks. I am lucky on the shavings. I have a wood stove for heating, they all go to use. Nice saw-bench, I am building a beefy version (and wondering at the wisdom in that…oh well).

I’d LOVE to have a wood stove. A few of the local hardware stores sell some at good prices, but I just don’t have the time / money to tackle remodeling the shop (busting through a brick wall to run the exhaust pipe) right now.

Not in the shop, it’s in my house. In my shop I freeze like everyone else. Need insulation, want water-stones.

Very nice. That was indeed a treat to watch you build this bench.
I am sure you will have a life long joy out of this workbench.

Great project build. Great to see someone make an entire workbench with hand tools.
