We have moved to Gilroy California and it is once again warm. Today I dug out my entire horde of aircraft steel tubing. When you buy steel there is a substantial minimum order. When I built “Path” I had plenty of steel left over for another complete tandem. The entire horde turned out to be 55 pounds. We have hauled all of this along for five years now

I have the following sizes to work with:

½ inch - 8 ft
5/8 inch - 8 ft
¾ inch - 16 ft
7/8 inch - 2 ft
1 inch - 17 ft
1- 1/8 inch - 7 ft
1- 3/8 inch - 16 ft
1- ½ inch - 16 ft

After completing the inventory I have now cut four pieces of tubing, and the bearing carriers for the rear swing arm suspension. I then created a base board out of 3/8 inch plywood and screwed it to 2×2 frame. A full scale drawing is taped to the center line of the board and I am setting up supports for each component.

Next step is to miter each tube for a perfect fit to its mates. Then each component will be aligned and the assembly brazed together. Here is a photo of the base board and the supports for the dropouts and pivot bracket.
