Am I the only one that thought that SG had a giant castor hanging from his ceiling next to his solar tube? 
Hah! 
I carved a fake castor from wood and hung it up to trick the wife. She saw it, said "huh", then walked out. The 2 seconds of muted surprise was worth my months of work 😄

That'd be my air hose reel above the TS, great for blowing sawdust into the nether regions of my shop and directing the spiders out the door.
