A "Roubo" workbench is a traditional French woodworking bench (Hobelbank) as described by André Roubo in the 18th century. It has many nice features and work holding options so we began building one.
While the following build is largely inspired by the old sketches, many features and construction techniques were chosen based on what was desired and possible at the time.
First Attempt
Progress: nearly done
- legs need to be cut to desired height
- top needs final planing and even edges
- vise coming soon!
Limitations
At the time of the build, our wood workshop was pretty rudimentary and the ideal solution was rarely an option...
- no jointer (and no jointer plane until halfway in)
- no F-clamps of sufficient length
Room for Improvements
- harder wood
.......
- final plate size: 1800 × 800 × 60 mm
- made of ten 2000 × 80 × 60 mm spruce planks
- did not have a jointer at the time, so the glue bond between the sometimes curvy planks was reinforced by three M8 threaded rods
- 10 mm holes for the rods, outmost planks counterbored with 20 mm Forstner bit to receive nuts
- counterbore should have been the first hole to drill...
- legs (800 × 100 × 80 mm spruce planks) will be connected to each other by a frame at the bottom, perhaps with a storage floor
- the bench may still have to be bolted to the wall for maximum stability, we'll see!
- holes for holdfasts will be added as needed, the first one was already drilled when the tenons on the legs needed to be cut
