Invariably when doing a marathon casting session I get a build up of lead on the mold surface usually on top associated with the spruce cutter.
First question, how do you remove that. I tried local heating with torch but fear warping my mold or use knife edge and scrape off but don't like doing that because mold does get scratched in the process.
Second is there a way to prevent this. I tried some light lube on surface where 'leading' occurs but that always seems to volatizes and end up in mold somehow with results of poorly filled out boolits that requires time to clear up.
Thoughts/Suggestions?
