Brian's Auto Knitter Cylinder is a perfect and affordable option for your Auto Knitter CSM. (Sharah's Auto Knitter is a Canadian Auto Knitter.) Brian designed a beautiful CSM cylinder for Sharah's antique, restored sock machine. She suspects this cylinder may run a bit quieter than her original metal one. Since the cylinder is printed without supports, it is ready to install without additional sanding. The cylinder is equipped with the hole for the ribber arm guide pin, and is compatible with a ribber. Please allow Sharah time to test each cylinder to ensure functionality. Let us know if you need a different size (up to 100 Needles), and we will generate, print, and test!
