跳環製造機用線圈繞線器

I was surprised how smoothly the brass winding rod turns, even under tension, making consistent coils much easier than my old homemade setup. The wing nut to secure the wire end is a simple touch that saves me a lot of fumbling.

The included mandrels fit perfectly and make winding consistent coils a breeze. I've already made a batch of jump rings in under ten minutes.

The handle turns smoothly with just enough resistance to keep the wire from kinking, and the base stays put on my bench without clamps. I had a batch of coils ready in under ten minutes, and the included parts are all solid metal, no flimsy plastic.
