Diary of a Clock Repairer Managing expectations,

The photograph shows a device which I use to alter any pallet stones or impulse pins.
Take a 1/2in square section of brass (the exact size is not important) and drill in it a hole which should be a snug fit for a soldering iron bit. I place the hole slightly above centre. Unscrew the bit from the iron and reverse it, putting the pointed end into the source of heat. The iron is rated at 30 watt. It will heat the block slowly in about 10 minutes.
Holes are drilled to accommodate the staffs and if adjustment is required the gradual heating allows for adjustment at the appropriate time. If left for 15 minutes the block will melt shellac rapidly.
Rollers can be adjusted by simply resting them on the block, although pins can be made to fit the hole in the block and roller. I have adjusted in the past chronometer impulse and discharge jewels without any problems. The block rests on a piece of hardwood to avoid damage to the bench.
