Which part are you interested in? The 2nd row platform cabinets? If so I could work up some drawings to give you a close idea of how to build it. My dad is the real hero with those cabinets. We both worked on the design but he pretty much built them from nothing in one day.I am super impressed. Looks awesome. I would botch that job so badly with my 10 small fingers and no thumbs :). Envious. Are you interested in doing another one? If so, let me know.
I'd be happy to hop on a call too if you have specific questions about any of it.
