1. I need to be more accurate with my machining.
2. I learnt how to use a rotary table to cut gears.
3. I can now crack nuts with a home made sledgehammer.
4. I need better ear defenders. It IS noisy in operation – but it does work as designed and I doubt it will get a great deal of use, but hey, I enjoyed the exercise and that's one of the main purposes for me pursuing this hobby.

P.S. During the design process, I came across a useful little program called GearDXF by Forest Moon Productions. It helps with gear design and outputs a dxf file of your chosen gear.
