I wasn't entirely satisfied with the aluminum cube [lulabs.net], so after thinking about the design for a while, I decided to make another one out of stainless steel. Just for fun, I thought I would make all the pieces using only manual machines. How hard could it be?
As it turns out, it was quite a bit of type 2 fun [wordpress.com]. It sure was slow and repetitive work, but I'm pleased with the result. I was motivated to think about ways to be more efficient, like machining multiple pieces at once and using looser tolerances where allowable. The slow pace also allowed me to consider details of the design while making parts. I have never been a fan of taking things slowly, but this could be a good argument for it.
