I have access to a centrifugal molding system where I work. My mind is already spinning about what I could do with this set up. The only snag for me is that it can only be used to cast lead free pewter because it is mostly used to make items considered to be toys. The big question is can I use pewter ounce for ounce in place of lead. I would mostly try to make inline spinner bait bodies and offset spinner baits. My other question is can I use pewter in standard molds or is it too hot? We pour it at 500 - 550 degrees if that helps out. Thanks

Cant help you with most, but I can say that we pour lead at 650-700 deg.

Standard 92-8 (tin-antimony or tin-antimony+copper) pewter weighs about 62% as much as lead.

Mmmm how much and where can you get pewter. If you can put it in a lee pot and pour big jig heads that are lighter wieght that would be awesome. Sorry didn't mean to high jack

Pete Mo Qwack - If you are from Missouri, there is a place in Columbia that carries tin and all different formulation of lead/tin/antimony. I have bought tin from them, their name just slips my mind at the moment. They sell sell all sorts of relaoding supplies (powder, lead, tin). Pete #8

Pete you are the man!!!! I'm at the hospital in columbia. I just had my first baby, the sweetest girl in the world!!! Is the place called mid way? Congrats on the new addition!! I hope all is OK with the little one and your wife. Midway is the place! I had a senior moment and couldn't remember the name. I have only ordered by phone, but you can pick up the order if you give them some notice. Pete #10

I can understand the wanting to switch over with the laws the way they are here in Vermont. I live up the road in Northfield and I pour what I can legally. That of course leaves out the split shot and under 1/2 ounce sinkers. I've been doing the research thing on non-lead for a while and Pewter is looking better and better although I've been checking out this stuff from American Tin and Solder it's ATS 75B 75 Tin 17.5 Antimony and 7.5 bismuth. Good luck with the switchover. Fatman

Thanks again for all the info. I will soon have personal access to the pewter equipment and lead free pewter. I need to buy or make some molds. I am going to make split shots first to get the hang of it. I sometimes pour for our historical line of products like musket balls and coin replicas.I just need to make time for my stuff or go in on the weekend. The unit is centrifugal like I said before, but I could pour into standard molds no problem. I will only have to pay for the pewter I use so I will save tons of money. I would like to make a variety of items someday.

Common pewter alloys might be too hard for split shot sinkers - only pure tin or soft lead works for me.

Common pewter alloys might be too hard for split shot sinkers - only pure tin or soft lead works for me. I have been testing its softness and it is harder but it will still do the job. You just have to squeeze a little harder. I might also make the slot a little deeper so it crimps easier. I more likely move towards lure bodies and jigs. Split shot is just my starting point for mold making and such.

Here are the casting machine pictures. This mold makes musket balls which are easy to convert into drop shot sinkers.

Wish I worked for a place like that!!!!!!! I'd definately design some jig molds and pour a few hundred jigs at a time!!!!
Is your company giving you a discount on the pewter your going to use?? Let's see some when you finish Fatman

Let's see some when you finish Fatman I have talked to my boss about it and I will pay cost on the weight of pewter used and the guy who normally runs the machine said he thinks the mold making charge is $35. We have in house mold making and lots of anglers on our crew so I may be able to spread the fees out a bit. I might also have found a new source of income for the company. The tricky part will be figuring out how to make a mold around hooks. we normally cast solid one piece items. If anyone has info on this please let me know. #20
