I gotta say i was/am interested in these bars myself and was only having that batch of different size bars made up to maybe fill a void with bar mounts and shocks as i think this active idea is good and has different appeal than a standard bar and I may take stab at it next time i visit my folks as i will have access to the machine shop
I'd say to go for it Robb. You seem to have the means for doing this type of thing. I definitely do not, so whatever I do I would have to either improvise or invest. That makes it more difficult for two reasons. 1) I don't necessarily want to put out a product that looks homemade simply because that is not the way to do business, and 2) obviously, for a custom solution such as this I really have no desire or incentive to invest.
I've said all along that my main interest was the solution, not the process. So, I am MORE than happy to say to anyone, like you Robb, take this ball and RUN RUN RUN! The only thing I ask in return is a little bit of credit for having some ideas (and maybe a low-price production model WINK).
