I wanted to build this without welding but still have it adjustable for the initial setting up.
Step 1: Components laid out.
- 6 bolts
- 4 brass screws
- 2 pine 38mm square roofing battens
- flat iron base plate 350mmx 50mm x 8mm thick
- 2 rectangular tubing 400mm x 37mm x 15mm
- 2 pieces angle iron
- 4 NSK 608z bearings, preferably metal shield low drag type, not the rubber shield
- 4 drilled and tapped metal plates 5mm thick
