Week 7 (March 15 - March 22)

After calling a couple places to order metal for the links we found a local place. We learned about it when calling Coast Aluminium and they recommended Gorilla Metals. Gorilla Metals carries flat stock aluminium in the size we wanted to get, so we used it to make the links. We did not get the metal for the tilt cradle. This week we will get the metal for the tilt cradle and start working on that.

The tilt links are made out of aluminium 6061. They are a 1/4 inch thick by 1 inch wide. These are test pieces used to verify operation and motion path. If binding becomes an issue then they can be replaced by links designed to be used with flanged ball bearings for smoother operation.  

We completed the bars for the scissor lift. We cut the square tubing to size. These wont take much time to make as they just need to be cut and drilled. 

The links were supposed to made with waterjet cutting. However, in the interest of time and money we decided to make them by cutting and drilling flat stock instead.
