I have been making my own soft plastics for some time and I also cast my own bullets for reloading. I am wanting to start casting my on swing jigs but I would like to make them with removable hooks similar to the attached images. Where could I get the wire forms made like these?

Where did you get the mold? Usually the place who sells the mold sells the accessories for it.

Honestly, A less than $20 wire bender will probably get the job done. Looks like an easy wire fabrication.

Barlows Tackle might have something that would work for you.

You can also use screwloks if you have room.

You could check with Mustang Wire but if they don't have it you'd be buying a lot to get them made!
