Torpedo Model 18b

[bhtooefr]

I've mentioned this elsewhere, but decided to grab it out of my storage unit the other day.

Here's a blog post I did on it when I got it last year: https://bhtooefr.org/blog/2012/10/21/pi ... pecasting/

It really does need the type cleaned, I'll probably grab the toothbrush and isopropyl tonight.

Anyway, here's the photos:

Lid on:


Lid off:


This model supports dual-color ribbons, but there's a black ribbon installed. Metal spools, for what it's worth.

Serial number:


This one's from 1962, based on that.

Dem doubleshots:


Interestingly, the lettering isn't flush with the keycap surface. It almost feels like it's laser-engraved, even though laser manufacturing wasn't a thing back then, and when looking at it from below, it's quite clearly a double-shot.

And, the one problem it has:


The pin in that collar is supposed to be sticking above, not below. And, I can't get it pressed up. What it means is that it can't feed the ribbon to the right, because it has no way of driving the spool.

nice one.
As for your problem, how did you figure it has to be this way? I mean, the driving pin likely won't just drop and get stuck immovable there. I sometimes find myself in a situation where I think: "why the heck won't this work, lets apply brute force". Later I sometimes find I had a wrong assumption before and have to undo my brute change.
As I look at the pic:
The pin end looks "correct" as in: I would expect it to look exactly this way, assuming it's position is correct. I would expect it to look different if the pin "dropped". Coming from there I rather think the collar is upside down. Maybe the whole spool pin is dropped in upside down, although I spot a spring for spool fixation that does suggest otherwise.
Reverse thinking: Why would someone push the pin down if it makes the feeding impossible? If you can't push it up easily it's likely it couldn't be pushed down easily too. Just a thought.

Well, the fact that the ribbon had a hole worn in it when I got the typewriter was a sign that something wasn't right.

The collar may be on the shaft upside down, but the shaft is in the typewriter right side up, because there's a driving gear on it below what's shown in the photo.

I guessed so as for the gear.
How does the driving pin compare in appearance to the the pin (is there one?) on the left spool axis?

I'll have to look more closely when I get home. There is a pin there.

Damn, that type-writer looks superb especially the design of the huge spacer key into the frame housing (so elegant).

Amazing how older writing implements seem to now attain an almost perfect design symmetry that is rarely found in anything made now.

Thank you for the pics.....

So I think the collar must have been put on incorrectly whenever this was serviced last, or something. The shaft was in the right way before.

I've gotten the shaft out, although it looks like things weren't quite set up properly before, because there was a loose set screw that holds all this together (and I'm not sure how I'll tighten it properly in the space that I have to do it in).

Now I just need to come up with a sufficiently small puller to pull the collar off (it's got a splined interface, I can see by how much I've gotten the collar to move).

Put the shaft inbetween the open jaws of a vice with the collar on the top surfaces of the jaws and tap the shaft with a hammer, that's what I would do. Most likely hardenend steel the shaft, so it won't bend. Twisting the shaft while tapping it will ensure it comes out evenly.
The question I'ld ask myself: "why would a service tech put the collar on wrong" - it's unlikely (to me) that it is regular service task to pull the collars.

Yeah, I know.

But either the pin was put in upside down (it looks like the end is mushroomed a bit), or the collar was put on upside down.
