I want to try my hand at a rib relay. What can I say I like to tinker. I wont be trying this on anything valuable or shoot able so don't panic

I have an old junk set of barrels that I've already removed the ribs on. I've read numerous posts and viewed Dr. Gaddys picture trail about the process. I guess what im looking for is someone who has done this and could exactly tell me what solder/flux/supplies he used. I understand I need to tin with acid flux and acid core solder. Then flux with rosin flux and rosin core solder. Not only what products to use but where to get them. I've found places on line who maybe have one of the things I'll need but not the other. I also don't need 5 lbs of solder like some of the suppliers have.
Again im just looking for someone who has done this successfully, not necessarily professionally, who can point me towards the right products to use.
You can pm me or email at vince174@comcastdotnet.
Thanks
Vince
