Hi everyone, I had a mishap yesterday and hope others learn from my mistake. I had just wound up and put the sleeve on a large mainspring in a barrel, I use a Ollie Baker mainspring winder. anyway as I was holding the barrel with one hand I was trying to flip the switch with the other, standard procedure, the handle slipped out of my grip and spun. It spun so fast and hard that when the knob hit my knuckle it broke the handle on the winder 😯 . I have wound and unwound well over a 100 of springs with this and I just got careless. PLEASE be careful. It actually does hurt The mainspring winders do not take all the danger away from the task!!!!! The bright side, it hit the knuckle that was previously injured and I got the opportunity to make a new handle. William
