Hi trevor to do this i haven't made any precision measurament or so, much simpler, first i did the hole, aprox 3 mm, then close it using a epoxy mass i used a fine wire to do a hole about 1 mm. and thats all.
to fire it i use a folded sheet of paper, i don't pre heat the oil, just to mantain the fire on front of the tin until it lights alone, about 10 seconds, i don't want to risk my fingers with a match :o) i want to try to pump the oil back the system explained on that url on the wastewatts group http://groups.yahoo.com/group/wastewatts/files/Babington/Airlift% 20Oil%20Pump%20One.jpg tell me if you make it work, or if you have any trouble regards Manolo rolan Valencia, Spain http://www27.brinkster.com/manolorolan ------------------------ Yahoo!
