Yesterday I posted about my getting my Master of Engineering Degree. I showed you a bunch of the design work that I did. Here is some of the construction that I did.
urethane rubber. In the bottom right is the mold that I printed using FDM, above it is a spray can that holds a silicon release agent that I sprayed into the mold, to the immediate left of that is the hardener that hardens the urethane which is in the tin in the center. The scale I used to ensure that I had the correct ratios of the urethane and the hardener.
cutting fluid, so I really didn't want to be grabbing for my camera all the time.
counterbored holes on the bottom that I didn't have time to do.
