2.21.2009 (Saturday) – Day 31 –
Today we’re making progress on the Robotic Labyrinth’s central pivot and base where the game platform will rest. Even after spending most of the week in the hospital, Tom came by with a drive shaft for the project. He was feeling a little weak and had to leave early, hope he gets feeling better soon.
We cut a 3/4″ sheet of plywood in half and rotated the pieces 90 degrees from each other then began gluing and screwing the pieces together.
Reminiscent of Junk Yard Wars, we began cutting the drive shaft apart to use it’s universal joint for our pivot point. While I was out looking for parts Rich and Bob began cutting out a template to build a plate for our plywood base to sit on. This plate will connect the universal joint and the base together. I brought back u-bolts from an auto parts store to fit around the bearings, this kit is the Dorman 81002 U-Joint retainer kit. The drive shaft was from a 73 C2500 chevrolet 4×4. It was the from shaft for the transfer case.
