Getting back to the subject of my Heinrici, I havent had much time tospend on it over recently, but the latest is that, if I spin it clockwise (with heat applied) it does 4 or 5 turns. Spin it anti-clockwise and it does 1.5 to 2 turns, then stops and about 1/2 turn clockwise. So, it is obviously trying but not hard enough! (Sounds like some of my school reports!)
