Great work! Making me excited to jump into my White Lightning project!
I'm missing the tube from the ball dispenser to the gun.
I know its ribbed with a metal coil interior, I found some on eBay that looks comparable - ebay.com link: Dental Vacuum Suction Tubing Hose Corrugated 5 8 ID 10 Long Gray
Can you please measure the inner dimension of yours?
Also - curious if/why some vinyl tubing from the hardware store wouldn't work
