Tools and Materials:
Welder (MIG, TIG, Stick)
Angle Grinder with a standard grinding disk and several cut-off wheels
Oxy-Acetylene Torch (a plumbers propane torch is not going to get hot enough)
Pencil, Scratch-Awl, or soapstone
8' - 2" x 2" x 3/16" Steel angle (1/8" should be fine but I could get 3/16 local for a decent price)
Welders, grinders and torches are dangerous tools. All could be fatal if used improperly. It is assumed that you know how to safely use these tools before starting this project. Wear all the appropriate safety gear so you can use this after you finish. I can not be responsible for misuse of tools or this wheel chock. This is not a substitute for properly securing your motorcycle. This wheel chock must be securely attached to your vehicle prior to use.
OK, enough of that. Lets get started.
Step 1: Collect your material
I bought a 20' piece of 2" angle from a local fabrication shop for $35. I got 2 chocks from this piece with a little left over. Each chock will require just under 8' so it is OK to cut it down to get it home.
