Dial screw alternatives

I have a Lorsa P75 movement that did not have dial screws. I tried the screws out of P72 and they didn't fit.

Is there alternative to dial screws? I though about dial dots/strips but the movement has a calendar. Conceivably I could wrap the dial foot in dial dot material. But that seems like red neck engineering.

Any thoughts or suggestions are appreciated.

Thanks,

MikeCJ

I have a P75 with one frozen dial screw and one missing.  I grabbed my BestFit assortment of dial screws and found this one.  Then I fitted it to one of my screw plates.  If you have a screw plate and a lathe, this is an easy make.  The outside thread diameter is 0.8mm

Not all screw plates are the same.  I would not trust anything but the Martin Fils B 26 because that is the only one that worked.

I did a test this morning and #11 is too big.  Started doing #12 and the screw broke...lol.  Got it out eventually.

      Chinese clone demagnetizers

      By HectorLooi · Posted

      My mentor has been using one of the Chinese clones for several years. Seems to work very well. Just put the object you wish to demagnetize in the centre of the cross and press the button. One word of caution though, the quality and QC of Chinese clones can vary a lot. You'll never know whether you got a gem or a lemon.

      B-Dip residue?

      You could also use a very fine artist's brush to brush between the coils.  If you get a size 00 or even 000 that should be small enough for convenience, and with bristles so fine that they are incapable of damaging the hairspring.  Get a good one though, like Windsor-Newton or similar.  I have never had a Windsor-Newton brush shed on my art or other work.  You want a soft brush that will not shed.

      Sounds interesting but how do you push the button if you’re holding both ends? the large current draw overheats after 3-5 seconds and the thermister triggers. A great tool for magnetizing things but I’ve not be able to ever demag anything with it because the emf is so strong it pulls the item off center (down or up).   I paid $89 bucks for it from  CAS-KER, if someone on the board wants it I’d gladly sell it for $25 plus shipping (probably US only otherwise postal costs are prohibitive). Just sent me a note offline.

      Seiko 7N22-7028 Movement Identification

      By watchweasol · Posted

      Hi. First thing to do is measure your oil movement as the vx32E and the 43 look very similar but one is a couple of mill smaller the vx32E.  Also the canon pinion heights differ attached tech sheets for 7N22. And  VX43, check details on the sheets. 7N22A_29A_33A_42A_43A.pdf VX43.pdf Hattori VX32E - Specification.pdf Hattori VX32E - Disassemble.pdf
