Quote from: LarryInMichigan on April 11, 2022, 07:23:31 PMIf you don't find the original spring hiding in the phone somewhere, you might be able to use the spring from an AE dial in its place. There are plenty of junk AE dials lying around,Larry
Quote from: LarryInMichigan on April 11, 2022, 08:50:20 PMI was thinking about an expendable 1950s-70s AE dial. The spring is a bit different, but it will probably work.
Quote from: TelePlay on April 11, 2022, 09:49:29 PMOn the subject Northern dial, its leaf contact springs are on the top, the AE springs are on the sides. The Northern reminds me of the AE Mercedes design. Similar but not the same.The AE uses two offset dogs to open and close the AE leaf springs (shunting and pulse). The dogs would not clear the Northern parts when dialing, rotating.I can not recall working on a Northern dial but remember having one that had the leaf switches on the top. Two totally different designs. The main spring shaft looks like an AE mainspring shaft (the top spring slot) but the rest is different.
