Ahhggg! Having cleared all the accumulated "stuff" from around the Sprite I have tried to get it out from under my "See-Saw" storage. There is a slight clearance problem......When I designed and built the see-saw I had to make a second, lower pivot point, as the garage had low roof joists, but the lower car didn't need to go too far under. In my present garage I had put the lower car in first and assembled the see-saw around it. There is a couple of inches interference which I thought I could work around by lowering tyre pressure and jacking the whole see-saw up slightly. Except I had screwed the other "A" frame to the garage wall.
So I will have to take the top Sprite down and dismantle the See-saw.....grrrr
