主軸手搖柄

I was skeptical about the bolt mechanism, but it’s actually really easy to tighten and it grips perfectly for slow, controlled plying. No more fighting with my wheel's tension.

Finally, a way to control the drafting speed exactly how I need it. The bolt-tightening mechanism holds firmly once you set it, and it's a relief to be able to pause and check the twist without any rush.

I’ve been using this hand crank for spinning fine threads, and being able to go as slowly as I want is a game changer. The bolt holds tight once engaged and loosens easily when I’m done.
