IBM Model M Keyboard

[Computer Nerd Kev]

Anyone tried reassembling these things? I've got an M2 which had
the common faulty capacitor problem. Caps replaced and the
electronics are now working fine, but after hours of positioning
springs and key caps I just reached the "start again" point.

I've been following this guide:
http://jsyang.ca/repairs/m2kb/

I just need something to hold the springs in place while I put the
two halves together. Not to mention some way to really tell if they
are in the right position or not after that. Short of putting all the
key caps on and _then_ finding that one key doesn't feel right.

Tried a tad of "super glue"?

The idea is that they're free to move at the base so that the lever
action works and presses the button when the spring buckles. If I
glued them to the button caps, they would be sticking out underneath
rather than resting in their proper position.

I need some way to pull them into the holes while I snap the two
halves of the keyboard together, but all I can think of is a very
big, very strong, magnet (and I don't have one).

You could try emailing the people at https://clickykeyboards.com/ or
UniComp https://www.pckeyboard.com/ for advice.

Super super magnets are on hard drives for Window 386 or pre 386

No, mine still works ok.

Gravity?

Well that's what I've been trying to use, and finding that it's not
strong enough to stop the springs jumping out of position as the two
halves of the keyboard case are snapped back together.

However I just thought that it might help to put some blobs of
blue-tack on the end of the springs to give them a bit of weight...

I gave that a try and either it worked or I've just found a better
way of holding the keyboard while pressing the halves together.
Picking Blu-Tack off 101 springs won't be a highlight of my life
mind you.

All working now, except F3 where I bent the spring by putting the
cap on incorrectly and (unlike the other times where I did that)
can't manage to bend it back in such a way that it still buckles
properly. It regsisters, but feels mushy. Still, it could have
happened to worse keys.
