Just swiped this pic off the net, there are different styles but they all work the same. -

Hi Nicklesilver any chance of a picture of the studding table sounds quite an ingenious device. I have always used the cock as is and threaded the spring when pinning (days long gone now) -

Question
JohnC 56
Hi all,
I have an old Bulova that has been on and off my workbench for a few months now - it was one of the first watches I attempted to service. The original staff was bad, so I ordered another movement of the same caliber (8AH, or ETA 1000) in the hope of transferring the balance complete. After receiving the parts movement, I then completely fouled up the hairspring on the "new" balance, due to a tragic combination of large overlapping centre wheel and the softness of old Bulova hairsprings (I now never dangle balance wheels from the cock - a harsh lesson learned).
I've just got a staking set, which makes transferring balance springs pretty painless. The solution to my problem seemed obvious - put the old spring on the new balance. I did it, and it's running well with decent amplitude and minimal beat error. The problem is that the watch is running 2 mins slow with the regulator as far to the "fast" position as it can go.
I was aware of the risk here, as I know hairsprings are vibrated to specific balance wheels. However, I thought it wouldn't be a huge problem given that the watches are the same caliber. How wrong I was! My instinct is that the new wheel is too heavy for the old spring, causing the slower frequency. Is there anything relatively painless I can do to address this problem, or am I out of luck, barring getting yet another donor movement? I really just bought this watch for practice, and cosmetically it's a mess. I don't see the point in dumping more money in. Hoping there is a quick fix, but prepared to live with a slow watch a few times a month.
Thanks in advance,
John
