O.k. I'm making a sandbox for my daughter, and I want a roof that will go up and down. Something that I can raise and lower with a pulley system of sorts... I will be using 1x8 cedar for the sides and just a few cedar furring strips to support a marine canvas top, so the whole contraption will be very light-weight. I want to use an iron bar, like some galvanized pipe, between the uprights, and a hand crank on ONE side to raise and lower the "roof".
Does this sound do-able? Has anyone attempted any piece of engineering like this? Would be glad to post more details (that are swimming around my addle mind) if the task sounds realistic. I have seen a photo of a similar set up:
Any help is indeed appreciated.
Thanks, Dave in Dallas
