Thanks for the input Will. I so far have not been able to find any pictures. I am still working on that. I have been just going on what my dad and uncle remember. They know they could back a Farmall MD with a loaded hay wagon into it. We still have the tractor so that is what I am baseing the lower level height on. On the upper level they remember having to duck to avoid hitting the tie beams. We have two other timber frame buildings. The barn which was built in 1853 is canted queen posts supporting principal purlins with common rafters. There is also another shed that was built sometime later with recycled beams from a mill close by. It has straight queen posts supporting principal purlins with common rafters. Other than the space limit in the attic what are the issues with a structural ridge? I didn't think the two and three way connections were ideal but I wasn't sure how else to make it work.

Thanks again

Chris
