Hard to see but that is two 4x6 oak beams I mounted together I smoked a 3/4 hp drill putting in the lags, even predrilling the holes. I plan to us this to hold logs for milling, so I will mount this on two I beams on concrete. I would like to have the rounds drop one direction, so they are consolidated automatically for splitting. I will add a few removable dogs for stability also.
