What have you got to say about the topic of: "Silicone Putty for Small Scale Mold Making". Here's how is started: "After reading Jason’s epic thread “Got Lead I’m Melting” I’m a little hesitant to offer "

After reading Jason’s epic thread “Got Lead I’m Melting” I’m a little hesitant to offer up this tidbit of information on making molds for - belly weights, jigs, tins, and so on. Obliviously this is aimed at relatively small scale production, for the people who only do a few pours at a time. I’ve used silicone putty to make jigs and such for some time, hot lead is near the outer limits for cured silicone . . . but it can handle it as long you construct your mold such that it is thick enough for the silicone to act as its own heat sink. This putty has the curious property of being able to stick to itself, if a second layer is applied very shortly after the first layer has cured, on the other hand it won’t stick/adhere to itself if one waits an hour or so before applying a second layer. This last feature has obvious benefits in constructing two part molds. Working time of the putty is about six minutes. For what it’s worth: http://www.clayalley.com/goop.htm Jason do you use a ladle, of some sort, to spoon fifty pounds of molten lead into your molds?

| Link in the 1st post goes nowhere... I have a 2 pound ladle... I've no clue how any of it will work out as I have not tried to pour anything yet. I assume you've seen my mention to the rubber molds from early ACME and Point Jude Lures??? I wonder what the material is that they are made of and how it compares to the silicone. I'll have to look into it further. Sure wish the days were longer.

 Doubt that the early ACME rubber molds are silicone. They might be polysulfide rubber though - I'd have to see one to tell. The silicone putty is great for small jobs, anything large scale and you would be better off with pourable silicone molding material. I'll show you tomorrow, if you can make it up here to the Museum.
