Ring terminal for 1-72 screw?
Posted by kasskaboose on Thursday, September 21, 2023 6:48 PM

While a dup from the eletronic forum, wasn't sure whether I'd get an answer faster here or there.  Cheers!

Can anyone pls suggest where to purchase ring terminals for 1-72 srews?  They are to connect wires to a screw that's through the Atlas turnout hole to power the frogs and remotely switch the throwbars.  Of course open to other ideas. 

I scoured online and talked to an electronic supply store associate.  The largest I can find is a #2 which, from an earlier discussion here, suffices for a 2-56 screw.

I only have a handful of Atlas turnouts with the metal frog. On those I threaded a brass screw, slotted round head, and when the screw was 'snug' I filed the slot just a bit and soldered the wire in the groove.

No terminal necessary.

 A short piece of brass strip and drill bits in a Dremel tool and you can whip up a half dozen or more in no time. Get a thin enough sheet and cut them out with scissors.

Just get some #1-72 washers.  Put one on the screw to clamp the #2 terminal.

Great idea! I ordered the terminals, so all set!  Shockingly, there are vendors for things outside Amazon, online train stores, ebay, etc.!
