New Tilting A-Frame for Osprey Vipermax
Just arrived from Mark at Marine Fabrications in Staffordshire.
Started this nearly 18 months ago. It needed to be able to tilt forward so that I could still get the RIB into the garage and also it needed to curve out over the transom to leave space for the aux. Since I would not be able to get the boat to the fab shop I knew I would have to get all the curves and angles right (hence the 18 months!).
I first got Mark to make me up the lower support arms so that I could fit them to the boat and then have four points on a plane to draw up the rest.
Had to remember how to do trigonometry calcs again.
Also made a prototype with waste pipe.........
