I built the lid shown previously but it was too heavy. I didn’t take the weight of the paint into consideration and I used an entire gallon of paint on it as glue. I was surprised too. I need to be able to lift with one hand while raising a wall and it was too much. So I free cycled it to someone to use as a slightly elevated platform. The new lid will forego the plywood and be Foamular, possibly 2″, skinned with canvas. That should reduce the weight by about 80 lbs maybe more. I hate the wasted material but there was nothing to do about it.
