Ray summarized irs use a half dozen posts prior to this one.

....oh maybe you know itís use now but forget again when you find it! Happens to us all....

Terry
I have known it's use a half dozen times. When I find the tool again,I will probably remember it is a cool tool to own, I probably won't remember why.

Next time you find the tool park it on a AE35 or AE50 Plunger or in the receiver end of a type 38 handset. That will help you remember!

AE had straight rubber cords...is that what It Is?

Were you missing just the plunger, not the nut? Did you find or cut down a plunger from an 80?

Terry

No, it's a cloth cord. I had the threaded portion, and Yes, I cut down a clear plastic plunger from an old 80 I had laying around.

So you kept the wide base part of the AE 80 plunger, shortened it and then rounded the cut end? Good fix that will not fall out. I fixed a 50 in a very old house once where the plunger had been unscrewed and put together again with the plunger upside down. Thus it could be lifted right out and just stayed in place by gravity. And, it no longer worked the phone properly.

Yes, exactly. I put the little step end in a cordless drill, spun it up, and used a sanding wheel to make a perfect dome shape on the plastic cut off end. I used some light hair clipper oil on the plunger, and it cleared it up like glass! Works perfectly now.

As a little side note with these AE models, as I'm sure you all know you can hear them go off hook from ACROSS THE ROOM. I've been messing with the contact placements on phones that go POP when taken off the hook, and I've found if I just adjust one set to close shortly after another, the pop is removed. I know this is common place on WE and other models, but the AE early phones always have that POP! and it DRIVES ME NUTS!!!

Yes, described perfectly...can hear it across the Room! Other solutions apparently is to add (is it?) a Varistor across the receiver capsule. Like they eventually did in newer AE receiver capsules. Interesting that you can adjust the hook contact timing to eliminate the pop. Maybe the contacts go out if adjustment with age?

I've had 302's make that pop, and it was found out that they contacts were making contact the same time! Stretching one out a little fixed the issue, I've had to do it a lot lately as a matter of fact!

I used to have a few varistors, and did in fact use them to aid in pop reduction. I just love how the 302's made it where you didn't hear a single peep going on and off hook - quality engineering.

I've got an AAS in CNC Machining, and I can tell you even on a manual machine, you'd have a few hours in making that one tool...Very nice.

I've discovered that little can be done other than a varistor to fix the pop on a 50. I adjusted the contacts two times, where one would close before the other, and it looks like one set of contacts purely dictates when the receiver is allowed voltage, resulting the in the POP....I guess that would be an easier place to put a varistor than in the handset....

Couldn't you just put a capacitor insted of a varistor? My mind tells me that the loud pop is the sitting 48vdc on the line, before the POTS service sends you the AC...A capacitor would block this DC, and then allow the AC to flow in....

Both the Plunger and nut Ray... The set?

Great deal if so!

Robbieís Monophone Tool is the original, the reproductions didnít loook like this but they do the same job.

Terry

Yes, Terry; I didn't want to get rich, just provide we collectors with the necessary parts to put their phones together. As for the tool, yes the photo of Robbie's is an original design. Gary Goff & (I believe) John Infurna improved on the design with a "T" bar through the middle (instead of the knurled ring) for getting a better grip on hard-to-turn nuts.
