Top is DF 2×12 ripped to 4.25”, except where a 3/4” strip of bubinga was added in 4 strips. Top is attached to the base with 2” tall, 2” wide, 3” thick tenons sitting in dry sockets so the bench can be disassembled into two tops and a base for moving. There are elongated holes for screws through the top stretchers to secure the top, but I found I didn’t need them. Base is DF 4×6 ripped to 3.25” by 5”. Top stretchers are connected with hunched mortised and tenons. Bottom joints are double mortise and tenon. Inside (corner) tenons are 1” long, 2” wide, and 3/4” thick. Outside tenons are 2” long, 2” wide, and 3/4” thick. Outside tenons are also drawbored with 3/8” oak dowels. A 7/8” x 3/4” rabbit runs on the inside of the bottom stretchers to support the half-lap pine shelf.

Chop is another DF 4×6. Head of the chop is laminated with bubinga and DF, then 3/8” oak dowels driven through the top and bottom of the head. Inside of chop is lined with leather. Chop is supported with a Lee Valley screw. Parallel mechanism is 2 – 18” pieces of steel c-channel in an X. The ends of the c-channel are have several 1-1/4” washers riding on 1/8” pieces of aluminum inside the mortises. Top of the X is pinned by 5.25” long, 1/4” diameter stainless steel dowels. Space inside the top of the mortises is maintained by more 1-1/4” washers.

Dog holes are inline with 2 of the bubinga strips for strength. Wagon is a Veritas inset vise. I may add a second inset vise for the other dog-hole row, as I want to do curved/round projects, and 4 points of contact seams appealing. I made 10 dogs that are 5” long oak with a beveled top and a bullet-catch in the center to stay in the holes. Also picked up a veritas planing stop for the double-dog-hole-rows.

The maple center divider can come out, but I’m too lazy to pick it up and turn it over for a planing stop every time. I made 2 depths a little over a 1/4” in depth connected by a slope. The edge of the top stretchers have a matching slope. Pull the end of the divider and it raises 1/4”. Push, and it drops just below the surface. As soon as I find a nice handle I’ll add it to the end.

Whole thing is finished in lots of BLO. I plan to make a tool box to go inside the bench, but that will be a different project.

How is the inset vice working for you? It’s a tempting purchase because it is so compact and easy to retrofit, but is it durable and substantial enough?

Great bench.

The planing stop is very clever and I don’t recall seeing that before. My top is also fir. I’m really curious how it will flatten with those bubinga strips. I flatten around once a year or so. I’m curious whether the fir will drop lower than the bubinga (being much harder). It won’t affect use of course. My wagon dog is much harder than my benchtop and the plane does just fine on it. It’s just a little jarring when you feel the increased resistance. I like the lamination; the more glue the better! As you can tell, I can talk all day about benches, so I’ll leave it with wonderful bench!

It was just installed recently, so I’m not the voice of experience on it. I did my research, and most people love it. there was a youtuber who said the aluminum carriage started getting loose over time (3 years of heavy use), but that Veritas had replaced it no charge. I’ve heard nobody say they regret it. my initial impressions is that it will be more than enough for what I do, as long as I don’t try to get pipe-clamp level of pressure out of it.

The contrasting wood looks awesome. It should provide years of service.

BLO = Boiled Linseed Oil. It’s a type of finish that’s been used for a few thousand years. It’s is, or used to be, the base for oil based paints. It’s also the reason never to leave oily or paint rags in a pile. It polymerizes when exposed to oxygen.

Very nice work! I like the stop, pretty clever. When you’ve used the vise a while will you update this? It’s a tempting purchase until I can build another bench.

Sure will! I got two projects coming up that should judge it fairly well. I should have an impression of how good it is by the end of them.
