The purpose here is to start a thread, that if it works Steve will put in a permanent file. Steve informed me that starting a new forum was difficult with this software as once you do it you cant remove it.The purpose here is to pass along to others all the little tricks of the trade , that has anything to do with dispensing. There are quite a few old timers like myself, Al, Bob and a number of talented opticians of all ages on this board.In light of that i am going to start off with a relatively easy one dealing with the removal of a screw from a metal frame, that wont seem to come out. Quite often if you heat it slightly in a salt pan, then turn it slightly to the right , and then to the left the screw will come out. I am going to try and post at least one new tip a week, until i run out,and i challenge the rest of you to do the same and maybe we can make this a thread to remember
