Is there enough demand for these Hankin boards Mike to justify all your hard work and time, or is it a matter of developing a working proto-type and a few brand new boards to start off with, then produce on demand ? Is tht the way you are approaching it ?
P.S - I take my hat off to you because you are extremely talented to be able to design and engineer all these boards, not to mention find and locate all the hardware, do the CAD drawings and then work out all the nuts n bolts. That takes patience and talent which you have in spades. Well done mate.
