There's been no updates for a while as I've been assimilating Jonathans reading list! LOL. Thanks to everyone who has helped, guided, suggested and corrected my understanding. I've progressed from not knowing what I don't know to knowing enough to know I don't know enough!

The design is done, I've put the crayons away, the fiddling with it over and now it's time to get some parts to fill it! So with a little luck I'll come back in a couple of weeks with some goodies and get cracking with it. Next target will be getting the frame parts machined and assembled and the unit constucted by the end of November!
