Prior to this point, all my experimentation has been done on my desk. Having to move components and equipment around becomes tedious, as well as the lack of workspace and ventilation being irritating. With enough space in the garage, I decided I was going to finally build a proper workbench. I found quite quickly that most pre-built benches available commercially lacked depth, as I prefer to have a large amount of soldering space and equipment at the rear.
After browsing through at least 10 different designs from various blogs, I settled on a design brochure from Bunnings Warehouse. I found that this design was fairly cheap and simple, as I intended to expand it at a later stage. I created the design in Google Sketchup, fixing a few dimension misprints and adjusted the scale to fit my size restrictions (1800x760x800mm approximately).
As illustrated, 4 main dimensions of wood were needed.
70×35 (8 pieces of 755mm, 2 pieces of 680mm)
90×35 (4 pieces of 1060mm)
70×45 (2 pieces of 1200mm, 2 pieces of 760mm)
Any surface of depth 45mm and total area 1800×760
The yellow structural pieces account for the unavailability of a 70×70 timber quoted in the design pamphlet.
Though at the time of purchase, the bolts and screws had not yet been planned, the assembled workbench uses the following:
- 2 pieces to form 70×70 with glue and 4 small screws each.
- Legs to the lower cross braces with 1 M8 bolt each.
- Shelf planks to the lower cross braces with 8 M8 screws in total.
- Legs to the upper long beams by an M8 bolt, above this will be an M8 screw sitting perpendicular and fastening the cross brace to the long beams.
- Bench Surface to the cross braces with 3 cup-head M8 screws. The placement prevents flexing of the bench top and keeps screws clear of the primary workspace.
