Hi Everyone , I am looking for a winding crank for a German made Excelsior cylinder phonograph ( EWC of Cologne ) as per the picture. it is quite distinctive and was used on the Excelsior " Pearl " machine sold in UK and quite likely other similar Excelsior models. Please look in your spares boxes to see if you may be able to help ! Kind regards Dulcetto

Hi, there is one which looks similar currently on French Ebay on buy it now for 12 euros with 18 euros postage. It is obviously longer but presumably you could cut it to length and tap thread on the end.
Just go to ebay.fr and search for phonographe - it is described as ancienne manivelle de phonographe...
Cheers

Thanks for the heads - up ! Not as simple as it sounds though -- the thread on the original handles are not standard a modern metric thread -- probably an old German thread that is no longer used -- German metric threads were slightly different 100 plus years ago so re-tapping a new thread end not as simple as it sounds . Appreciate the call though. Regards Dulcetto

What's the thread pitch and tpi count you need?

If my measurements are correct on another EWC, the diameter is 5,83 mm and the pitch 0,9 mm pitch. So if it is impossible to find an original I suggest running a M6 1 mm tap to the thread. It's such a short threaded section that you will never spot the difference and will make very easy to fabricate a replica of the crank.
