I have multiple Do-It Molds and pour jigs, spinnerbaits, etc. For most people, I think it is best to just have someone pour the heads for you and then let you bend the wire, paint, insert weed guards etc. You can get raw poured heads pretty cheap.
If you get into the whole process from the start, you have to buy the molds, the melting pot, ladles, and then find lead, which isn't cheap anymore. The upfront costs are significant unless you are going to pour hundreds.
I am glad to help if I can. The lead pouring part is no fun. The bending, painting, etc part is great. Let someone else do the crappy part.
