I have approximately 100 lbs of range lead cast into soda can shaped blocks about 8lbs each. I have new Lee pro 4-20 fitted with a PID controller. I want to smelt these down to nice little bars for casting. I have metallic antimony in pieces approximately ¼ inch and smaller, and I have 50/50 solder. Unfortunately, I only have access to an area to do this in for several hours at a time.
How long would it take to melt a batch of one 8lbs block plus antimony and tin?
Would I be able to do 2 batches at a time (approximately 18lbs)?
Will I have problems with the antimony or does it alloy in pretty quickly?
Thanks for all help, wisdom, guidance
