Step 1: Material List
1 qty old bike fork
1 qty storage container of your choice. I used a 27 gal. Rubbermaid one from Costco
1 qty old bike wheel. The smaller the diameter the more it will tend to bounce over bumps
6-10 tech screws or any screw suitable for attaching your bin/container
1 qty child tag-a-long bike hitch. These are easy to make but so easily available why bother
? qty of wood for deck. What do you have laying around. I had a scrap of 3/8" plywood from another project
? qty of conduit, pipe, tubing or misc. metal. I used about 3 and 1/2 feet of 1/2" EMT electrical conduit and 3 and 1/2 feet of 3/4" EMT electrical conduit. I also used a small length of 1" square tubing because I had it and ran out of EMT. Use what you have.
4 qty pre-bent 90 degree elbows. You could weld straight 90's or use a tubing bender. I was going for maximum convenience in this step. They are pretty cheap from the hardware store.
4-6 qty bolts variety of lengths. I used some bolts to strengthen all the joints. I found misc ones that fit snug in the pipe, cut them to extend a couple inches into the joints and welded them all the way around. (probably over kill).
2-4 qty of plate steel. I used some scraps from my junk bin. They were brackets off some old equipment. The pieces I used were about 1/8" but you will need to use metal thickness based on the loads you intend to carry. There will be flexing at the joint if you go too thin.
