Lets see if this works. This pic is under "progress, slow but sure" thread on Aug 15. The strongback here was built for a Cosine Wherry, and then modifies to add the legs and wheels. It has been one of the most handy setups in the shop. For the Spring Run, I simply set the box strongback on it. When the hull is done, as shown, I can put cradles on it. When not used for boats, I can put a plywood top on it 16' long. And it is so easy to move that, like Ross said, sometimes I have to block the wheels. Well worth the effort to put it together.
