I threw away the old chemicals and used some new pre-coated boards. A much better result. For any Aussies - the pre-coated boards they sell at Dick Smith are the perfect size for both the Pickstep and the 4 axis BOB. Probably not a coincidence (Alan ?)
Well.. The first of may build steps. I'll drill tomorrow and should have all the components for the picstep and BOB assembly next week.
