I know it looks unstable but there's more to it than meets the eye. The vertical supports extend into the ground 18" and the soil around them has been hand packed but after a few rain / dry cycles, the ground will be like concrete. The tops of the vertical supports have a "V" cut into them to help stabilize the longitudinal logs which are pinned to the supports with 2' long rebar. Time will tell if this will be good enough or if I need to stiffen it up. So far I've only loaded about 10 logs onto it and it seemed fine. Worst case scenario, I have to redo it

. Not really a big deal though, as it wasn't a big project and only took a few hours to complete.
Now all I need is some logs to mill. Pretty hard to find around here. My property was logged before we got it and I'm not allowed to take from the crown land around us.
