Inspired by the workbench design of 'JenniferG' and the customizable version of it made by 'svhb'.
Living in Europe I did not have access to 2x4 beams but use a 50x100 mm beam (shaved to 44x95) instead. Unfortunately the customizable version of 'svhb' did not provide a way to change the beamsize so I came up with a more customizable version of the workbench.
Due to my workshop's layout I also needed a rear overhang on the workbench, and needed to be able to specify the depth of this overhang.
So I came up with a more customizable version of this awesome workbench.
It is fully independent of unit of measure. Just put in all values in the unit you need and the output will be of that same unit.
The following parameters can be specified:
- Bench Dimensions (width, depth and height)
- Thickness of the wooden sheets for top and platform surface
- Size of beams to use
- Front and/or rear overhang desired, including depth
- Target spacing between the supporting studs
The following step by step build is based on my own workbench, as per the dimensions of this thing.
I have used:
- 44x95mm beams
- 18mm MDF for the surfaces
- 6x80mm screws for all connections
- 8x120mm screws for some structural connections
Further I have pre-drilled all screw holes on the beam where the screw is inserted. This to ensure that the beams can be nicely tightened together.
Step 1 - Prepare wood
Use the output of the OpenSCAD console and paste it into the 'Beam Calculations' Excel file, Column A. Update the PivotTable and you will get a nice list of beam lengths and quantities needed.
Use this as input to cut your beams into the required lengths.
I personally like the use of 'Cutlist' to determine which lengths to get from each beam to minimize waste: https://jonathan.overholt.org/projects/cutlist
Step 2 - Assemble the legs
Start with the assembly of the legs.
Make sure that the legs are straight and have exact 90º corners.
Also ensure that the 2 beams on the bottom, which are going to be the feet, are level so they have a good and even contact surface.
Start with the 2 full lengths
Screw down the 2 lower pieces
Screw down the lower brace
Screw down the top brace
Hammer the middle section in place
Screw down all beams
Step 3 - Assemble the workbench
Start assembling the workbench by mounting the top inner beams.
I have attached the inner beams (both for the surface as for the platform) with 8x120mm screws, as these are the most structural beams of the workbench.
Assemble the top inner beams using 3 screws of 8x120mm per side (12 screws total)
Assemble the lower inner beams using 2x 8x120mm screws per side (8 screws total)
Assemble the studs on the lower beams.
Assemble the studs on the upper beams
Assemble the small studs on the rear
Assemble the rear beam to the studs and legs
Assemble the small studs to the front
Assemble the front beam to the studs and legs
Step 4 - Assemble the surfaces
