After looking at the walker, staying away for a few days, and then looking at it again I couldn't leave it with square bars. I always know when it gets to this point that if I don't fix the thing that is bugging me I will hate it forever. So I have rounded up all the edges and moved on. Here is the walker with a coat of paint on it.
Automata is a creative blend of my life interests , engineering, art and woodworking.
