Just found a great book on rules for watch timing. Rules and Practice for Adjusting Watches by WALTER J. KLEINLEIN author of Practical Balance And Hair Spring Work. This book goes much more in depth than DeCarle and others. Actually breaks down for beginners and highly skilled workman. The beginner section is broken down and explained in depth step by step for each position and what to do if in the minus or positive in each position. Also gives hundreth of millimeter side and end play for each train gear and pallet and escape wheel. Wich I have always wondered how much was correct and never found anywhere else. Highly recommend for bench top reference.

For the Alum thing, I use a trick.... Bung it all in an old glass Thermos flask overnight. Works a treat as it stays reasonably hot for hours.

Of the two Jacobs chucks that came with my lathe, only one fits the spindle threads. One is a Rigid brand, which may have come from a drill motor; It does not fit, FWIW. I set up the Unimat SL1000 for drilling with the machine "vice" to hold the part to be drilled. The drill bit will have to get between the barely open jaws in order to do the work. It will be tight but looks doable. I won't be able to get to the actual drilling for a week or so, but will report back on how it works out. Cheers, gents.
