Hi Ray
Not sure what Ibam doing on this forum. Think my answers are to the wrong place. yews the roof comes off and there is about1.25' headroom to work.
Struggling with photos, found that my computer didn't have Jpeg format, it is Apple Mac air Apple have now sorted that. Trying to use Colin Bishops instructions to upload but I don't think he has written it for Apple because I can't find his instructions.
Measuring the movement on the boom that is about 10". Is that a lot for a lever system? Would I need to source a powerful servo for this.
Hvent given up on the photo issue yet
Many regards
John
