step 7Support Base
This lens scaffold we now have needs to rotate around so it can aim up at the sun. To accomplish this we came up with a super simple, super sturdy base made from 5 blocks of wood.
Materials Required:
You can see the basic design from the diagram. The planks are held together with large lag bolts - to use these, drill clearance holes through the first part (as wide as the part of the bolt without threads) and a pilot hole through the second part (not as wide, so the threads can bite into the wood). Then you screw the bolts in with a ratchet. It's very tight, and very strong. A few of these should hold each part together.
You'll want to measure the lens scaffold first , then slightly overestimate the width for the base so you can get it between the two supports easily (the spacers will take up the rest of the width).
Mount the Lens Scaffold
We want to put a couple holes at the top of each support, and insert a suitable collection of a spacer, washers, a nut and carriage bolt (see the diagram).
Once the pivot is together, you can use a wrench to tighten the bolts and lock the scaffold in position.
Materials Required:
- One 8 foot 2x4
- Around 8 feet of 2x6 board
- 8 medium lag bolts
- 2 big lag bolts
- 2 carriage bolts and nuts
- 6 washers
- 2 wood spacers (use the lightening holes you cut out for the scaffold)
