I will cut some strips of wood and make up a pattern of one side of the scissor so that I can see how it will operate and then I can work out the amount of travel along the top and bottom rails.
This is a motorcycle one which has a height of 870mm and a low of 350mm . It looks like the arms might be about 500mm so at these measurements it will give me an actual lift of 320mm .The 870 deck height is achieved but the base being 350 above the ground. I might make the test arms 600 long to start with and see where that takes me,
