dino, keep posting. seeing what new inventions that are out there is very interesting and informative. with regrets to ian, i think posts from inventors adds insight. in the cases where the emotions run a little warm, the interaction can be informative, if not entertaining at times.
it also causes us all to think about how and why we do things. it's just jigs and fixtures taken to another level.
is there salesmanship involved? always. the biggest selling job is when you sell your wife on the idea that you need a new tool. see, we are all salesmen and inventors at heart. the inventor is not selling as much as he introducing you to his new creation. he just wants you to understand what it can do.
this appears to be dino's drive. he just wants a listening ear. from what i've seen, your eyes and ears will both enjoy, and you will count the benefits on all your fingers.
