Guild School 2017, students had the opportunity to learn to do a spiral turning for a lamp with Artisan, Iluia Chin Lee.
I admit it, I have fallen for my lathe and enjoying romancing the lathe... and I also read lost art press' blog when I want to divert my brain...
Think turning a spiral is a challenge? (Definitely, I haven't tried it yet!) Why not try to do this for a cathedral? I have never met anyone associated with the Lost Art Press (LAP), but gosh, this makes me want to buy the Charles Haywood Book(s) from LAP. Look for a post from June 12, 2017...

If the structure was 54' high how large was the cross slide?
Gosh, I wish I could time travel to see how they did this!
