Anyone familiar with Seiko 5J32A movement? Apologies if this is not the correct place to post this. The movement has been stripped down, cleaned and I'm reassembling now. Installing the train wheel bridge goes without issue but after a lot of trials I have this issues.. when the crown is pulled out to the 2nd position, the hack is engaged but when it's engaged I cannot turn the crown to set the time, if I gently push the hack lever away from the 4th wheel while the crown is in the 2nd position, then all works as it should. I have removed the wheel train bridge and the keyless works numerous times but cannot fine why it's doing this. Anyone have any ideas what I should be looking out for? Thanks. -
I have one of those and it's OK, but I prefer the Chinese Moebius knock-off. The metal gauze isn't removable, and I find that a bit inconvenient. Also, the Horotec style bottle doesn't agitate the epilame when you turn it around. From the post I linked, it seems the Chinese Moebius knock-off bottles are about $25. -
Well if you get the Jack & want to convert to speed control via potentiometer I can send you a wiring diagram & explain how to do it if needed it is very easy, I also changed the pulley to same size as on lathe so I could be sure the rpm on the display is correct. Dell -
Doesn‘t look like fake, but has not to be removed. -
