Ok so who bought the Flume books then,own up Andy or Tom ?

They sold 2 hours ago, thats no coincidence

lol, I was waiting till after Christmas so I could say I'd bought them with Christmas money but figured once the cat was out of the bag I better pull the trigger.

Strictly as they won't be here now till after Christmas they'll be bought with Christmas money.

Hi Team. Delighted to see all the activity and good shopping on eBay! I have been away helping dispose of a decent 10 year old Rioja and a Chinese feast - hands are now nicely relaxed for balance staff work... So let me try and address the helpful replies. 1) the dimensions we are looking for are 422 210 126 83 and 50. 2) Yes only one pivot is broken so 422 is a decent estimate - the rest is measured 3) Buying a lathe and learning those skills at 76 years old is probably an over elaborate solution for a 10 dollar problem 4) No I have yet to figure out how to measure the balance staff length on a bare movement - No need here since the old shaft gave me a good estimate. The pivot was bent and still in the movement and  the end shake was good. It broke when I tried to straighten it up ( yes it was heated etc ) The 440 option will not even let me drop the balance cock down - way too tall. 5) I think we have a WINNER and the prize goes to Bulgaria. The HELVETIA 32 gives us 422 210 125 90 53. the 83 vs 90 is the usual split collar balance spring fitting - an extra two thou there should be no problem and the extra thou on the roller shaft should also yield to a little fettling. Also to show it's Christmas,  Cousins have them in stock for £5. Got to be worth a try.

That's now ordered - Brilliant help as usual - Merry Christmas to all that did the research and we look forward to all those useful books being transferred to PDFs on here. No good turn goes unpunished. Also check sizes carefully before ordering on eBay...

That’s cool, thanks Rich. I just got two of Jendritzki’s books, really like the style.

I'm after the escapement adjustment one.

Lol, they were meant for you Andy, I doubt you'd ever beat that price. I am curious to know if they are the same same books with one of them revised. The book I have says Band 2 and 3.

I have seen it new for sale in Switzerland for 60 quid plus postage.

One last thing that might be worth knowing to ID the movement,  measuring the stem. And one last last thing, I can check the balance staff stock I have for it.

[hofnerpres]

OK if you can use the stem size to help , Using the DCN system A is 80  B is 140  C is 165  and F is 550. I can't find it and my daughter is just about to drag me out to socialise.  * It's just a watch Dad

Well to conclude this saga. The slightly wrong balance staff only needed remachining on almost every diameter including the pivots which were  0.16 instead of 0.13. and slimming down the roller shaft taper was fun. I managed on my little Dremel based model lathe with tiny collets - it runs remarkably true and fine diamond files will work. Needless to say the surface finish is dreadful but we got everything to fit nicely so at least the sizing and concept could be tested before I blow the budget on a Jacot Lathe. Good news we have a ticking and functional watch again. Amplitude PU is poor at 150 but that's a result looking at the moonscape pivot finishing. It's pretty piece with lovely dial and hands so we'll get it all polished up when the Jacot arrives. All good experience
