Now we are ready to cut some boards. I prefer to buy and paint all the boards I will need before cutting.( I have used the $10 / gallon paint sold through the Restore. ) This step should be easy to visualize – you will be creating a rectangle just slightly larger than the pane of glass. To fasten the 2x6s together, I use 3″ drywall screws and pre-drill a hole through the outer board being attached.
- Take two standard 2x6s (cell D3) and cut a corner off one end of each. The end of board starts as being a 90 degree angle. Cut from one corner to make an angle equal to your solar angle.
- Cut the top member (length = D11) and bottom member (C11).
- Attach the top member on top of the two sides.
- Measure down and attach the lower member between the two sides. The opening should be (B6 + B9)
