Hi Tim, thanks for responding. The timbercart is advertised as having a 500lb capacity. When loading any dry white pine timbers beyond 8"X8"X16' the cart starts to have problems. Also, the brackets do not fit timbers beyond 8"x8" very well. I'm using a fair number of 8"X10"X24', 10"X12"X22', 10"X14"X22' etc... and the cart tires just deflate. Yes, I have some changes in elevation and it's all on gravel. The handling issue is also getting timbers on and off storage piles by myself, into the shop and out, back to storage etc.. I'm trying to work on an idea of using two truck axles and fabricating & welding together a gantry type of system that would be easy to move around by a single person. Know anyone on shoestring budget who has ever tried this?
