Hello Joe Nice work, Sure looks Pretty! But one question, Is aligning up the threads on the screw with the nut, Have you found any problem with the nut being wedged in like that? Just curious? ;-) Joe my Rose follower has a lot of possibilitys. and I have a lot more pictures of different patterns and gear pitches, that I have tried, some are nice and others are ... But its all in the learing curve. (so to speak. ) Please keep up the good work, I very much like seeing what you are doing. Have a good night. C.A.G.
