Every woodworker eventually builds "The One." The bench that will last the rest of their life. The bench their grandkids will fight over. It needs to be heavy (so it doesn't move when you plane). It needs to be stiff.
I chose a modified Roubo design. This is an 18th-century French design. Massive legs. Massive top. No screws.
Material: Southern Yellow Pine
I went to the big box store and dug through the stacks of 2x10s looking for Southern Yellow Pine (SYP). SYP is cheap, but it is incredibly hard and heavy for a softwood.
The Legs: Lamination
I can't buy 5-inch thick legs. So I made them.
- Ripping: I cut the 2x10s into strips.
- Gluing: I glued 4 strips together to create a solid leg block that is 5" x 5".
- Mass: Each leg weighs 30 lbs.
The Joinery: Mortise and Tenon
If I screw this bench together, it will wobble in 5 years. I used Draw-Bored Mortise and Tenon.
- Mortise: A square hole in the leg.
- Tenon: A square peg on the end of the stretcher rail.
- Draw Bore: I drilled a hole through the joint and pounded a wooden peg through it. The hole in the tenon is slightly offset, so the peg pulls the joint tight like a steel cable. No glue is technically needed (though I used glue).
The Assembly
Assembling the base was a wrestling match. I used a sledgehammer to drive the joints home. Once assembled, the base frame alone weighed 150 lbs. I kicked it. It hurt my foot. The bench didn't move.
Conclusion (Part 1)
The skeleton is done. It looks prehistoric. It is over-engineered. Next time (Part 2), we build the top that weighs as much as a Honda Civic.
