I needed a sturdy bench so the choise fell on konstruktion wood. It's mostly from spruce and sometimes from pine. Spruce is a soft wood which suites my bench as the bench will take the hit before my working object. A problem could be with branches in the wood that can shrink and eventually fall out leaving a hole...
Construction is shown in plenty on the net. This pieces is originally sawn to 2x4 inch, 50x100mm and then planed smooth so insulation can go in easy and all wall stud are in the same sizes.
That's why 2x4" is really 45x90mm.
First step is not to glue anything. Planning the layout of all pieces so the branches goes to the underside och the table. And where that wasn't possible i cut out a 25 mm deep chunk where the branch was and replaced with a clen piece of wood - that I glued.
After glue time to plane. Here i manually take down the pieces that I used to replace the branches.
Then I set up the router on a sledge and planed both top and bottom side.
I used to have a Swedish workbench, Hyvelbänk=planer bench, which work very nice. Sadly it got "consumed" during a big boat build.
I tried the Roubo style bench and style but that didn't suit me at all. So I wen for a modern metal thingy instead. Works very good with a quick set function.
Then I mounted some oversized legs with big wooden screws so I can eventually get it out thrue the door :-)
Done. While working I have drilled some holes for mounting purposes in the benchtop.
I later added drawers below the benchtop.
