Need help with ferrite rod winding.

[RayRay1132]

Can someone please recommend a good manual coil winding machine for a ferrite rod. I already have one for winding transformer bobbins.
Thanks in advance, Ray -KD2JID

Why not put a bobbin on the rod?

That's how it's always done in radios, as you adjust the inductance by sliding the bobbin along the rod.

Good Idea, I'm surprised I didn't think of it myself. I couldn't find a premade bobbin for my rod so I made one out of cardstock.
