Great first build post to our new Momus forum.
I hear you when you talk about the amount of driling and tapping. I went out and bought myself a very basic bench top drill press and can't imagine doing all drilling without it. I would spend a couple of hours at night working on a piece or two. Any more than that then I would start rushing things and that was not good. Eventually I go them all done and it was really cool to see how the pieces scattered about my work bench came together.
It was all worth it when I finished all the components and put them together to look like attached photo.
Next step for me is the wood base and then the electronics.
