I'm resurrecting an ancient mirror project (my first). I'm polished out, have a tool and a tester, and will find a barrel or make one. I need to order pitch. [Thanks to Vern (N7GTB) on another thread who reported the status of First Discovery on the web - I was wondering too.] I'll be working in my basement, which at least has a consistent temperature. It currently ranges from 69 F on a cooler summer day to 72 F (or about 20-22 C) on the hot days (over 90 F/32 C) we had in Pennsylvania last week.
Seems like I fall right on the line between these two grades of pitch. I'm inclined to go to the harder one (73), as working it may warm it enough. And I'm told you don't want a lap that is too soft. Your thoughts and opinions are welcome. Regards,
