Does anyone know any of the following values?

Need info on screw sizes for multi-slot pay phones:

                        Western Electric/Northern Electric:

                                Coin Vault Door (14- or 30-type lock)

                                Large screw for coin chute

                                Upper Housing Lock (10-G, 10-H or 21-B)

                         Automatic Electric:

                                 Vault door (10-L type lock)

                                 Coin chute

                                 Upper Housing Lock (29-S)

Thanks

My NE233 has a 21B upper lock fitted with four 6-40 NC pan headed, slotted machine screws.

I'm not coming up with 4-36 screws for dials but 1/4 x3/48 like the finger stops.

Did you ever find the dial mounting screws? I could use around 30 or so.

Don't know why I never posted this, but some may find it helpful.  I managed to find a thread chaser many years ago, size 4-36.  Just as important, I also found the handle this die fits in.  Since 4-40 is easier to buy, I have found it handy have this to run them through to ensure they fit my dials.  I prefer to alter the threads on a replacement screw over running a 4-40 tap into my dial mount ports.  Since it is a resize, some of the recut threads will show a loss in fullness.  This has never caused me problems-- every screw I have treated this way started fine and tightened perfectly.  I found this by chance at a local flea market-- one of my more useful buys.

Hey David;

going over posts that I missed in the past:

Machine screws for NE and WE 3-slot vault door locks: 3/8" long - 1/4" x 28 screws
Upper housing locks on all 3-slots:                              1/4" long - #6-40 screws
All of these machine screws are slotted round-headed screws for authenticity with the exception of newer WE/NE 3-slots where you would sometimes find allen-head screws in the vault door locks.

Automatic Electric 10L vault door lock bars:                 1/4" or 3/8" long - #8-40 screws - slotted/flat head (these are also the same size for fitting the coin chute into a Gray Paystation cast iron top housing except the screws would be round/slotted tops on the screws.


                                                                                                                       Gray Paystation Co. top housing).

Adding to this screwy thread.  A potential buyer was interested in my brassed-out 151 stick.  The original transmitter parts need to be reinstalled.  I made an effort to get a shot of one of the screws that hold it in place.

The idea that a four-year degree is the only path to worthwhile knowledge is insane.
