Dude your friend has some serious skills.
Back almost 25 years ago I helped a buddy out when a hurricane came through and had knocked down 11 trees on his property. (His Mom's house, and his parents Antique shop and warehouses were also on the property. He was nbow running the Antique shop)
I started working there full time, first in the woodworking area, then moved to front of shop helping with sales, marketing, management and computers.
I got to do a lot of repairs on around 1800 and above furnature that was made on some of that style. God damn just repairs was a lot of fiddly touchy stuff for hours at a time. Building it out from scratch would have killed me.
Seriously that is some impressive work. Kudos.
