hi well where the hand sits depends on the clock ie the travel of the plunger if it has a long travel then 9 o clock is ok for preloading the clock but if it has a short travel I set them to 12 o clock but I ant come a cross a stranded place to put it as I sed you can heat it up but I don't like that as I have tried in the past and the time taken to prep the hand and so on I find the felt tip a porch much beater and all the ones I have dun are still going strong one thing you must not do is over oil it  all I use on the ones that I have dun is starret instrument oil
