I am making a new balance staff for an 18S Waltham. I think the balance is friction fit, however, my first cut 1.45mm was a bit too much and the balance fits but is not tight enough. I decided to leave a little lip so I can rivet it on as well (let's see how that goes:). I then cut the hairspring part at 0.9mm and the pivot at 0.12mm; cut down to 0.2 and then reduced using a stone. I had to move the Steel Rod out as I had worked my way in too far with a failed first cut on the balance part. I then cut the roller table side and angled the largest diameter. Tonight I cut the lower pivot. Sent from my iPhone using Tapatalk Pro

Hi all. I'm servicing a EAT 2824-2 movement I bought of an auction website. There was no stem and I took a gamble. While waiting for it to arrive I ordered a new generic stem, and assumed it should fit. Taking the keyless works apart, I could see the remains of the original stem still in situ. Comparing the original to the replacement, they are different across the flats. The original is 0.51mm. The replacement is 0.74mm and will not fit the sliding and winding pinion. Does anyone know where I can source an original with 0.51mm across the flats?

I was in the same situation, what I did was to find this 11dp movement listed as not working but balance swings fine. I bought it shipped for $4, the balance worked amazingly well.

Started cutting the bottom half of the staffSized it against the original staffGraved it down to about 0.2 mm and then filed it down to size with a stone and oilI then burnished itThen i fitted the roller table to make sure the staff was the right size.I then fitted the staf on its own in the movement to make sure the length was right and the 0.12 staff pivots fit into the upper and lower jewel. It was a little long so I mounted the staff in the lathe and tool a little off the top pivot.I compared the two staffsI Then fit on the staff loosely and assembled the unit as a final check prior to staking on the staff.All done for now. Tomorrow I stake on the staff and roller table and test again. Sent from my iPhone using Tapatalk Pro
