I am now replacing the hairspring on the balance wheel.The Pocket Watch is a Sterling model 7 Jewel 1877 movement
Afterwards are there certain steps to take to properly setup the Balance wheel ?
I never tried this before
mainly to hard to see these little parts that hold on to hairspring and because of my lack of experience and no one to ask when I run into problems
Thank You Rick

Americo...You will have to vibrate the balance spring in order to get the proper oscillation rate. This will tell you where to pin the end of your hairspring. There are special tools to assist with this, but it can be accomplished without them. Here is info from a previous post of mine:

Suspend the balance with tweezers on the hairspring at the point where the regulator would be centered. You will need to be able to time precisely 30 seconds, so a stopwatch function on a cellphone would work well. You will also need a domed watch crystal. Let the balance wheel oscillate while you just touch the pivot to the glass crystal. Watch one of the balance arms very carefully and start counting to 75 at the same time you start your stopwatch. Stop the stopwatch when you hit 75 and it should be at exactly 30 seconds. If it is less you know the problem is either a too light balance or a too strong hairspring. If it is more, then the balance is too heavy or the hairspring is too weak. If you move your tweezers toward the end of the hairspring, you are in effect making the spring a bit longer and weaker. If you move the tweezers toward the collet, you are making the spring shorter and a bit stronger.

Reasoning:

18,000 beats per hour, 9,000 each direction.
300 beats per minute, 150 each direction.
150/2 = 75 beats each direction for 30 seconds.

This will take a little practice to do, but it does work.

PS...Before you do all this, you should check the poise of the balance with the roller table on and the hairspring off.
