Thanks for your support and encouragement chaps.
With a long term projects these important milestones help give your enthusiasm a boost. Once I have the last motion link made and after a little more tinkering, its going to be set aside whilst I get busy with a little short term project I have planned then I'm going to start on the tender, I have a part finished tender that I bought so I have a bit of a head start, once I have that finished it will be dusted off and a start made on finishing it off, but there is still a lot of work to be done on it.
Thanks again
Stew
