[WTB] SSK bolt mods

[y11971alex]

Want to buy 2 SSK bolt mods.

How much would you be willing to pay? It would take some driving time to the art store, messing around, packing, etc.

And postage to Canada will be at least $8-$10, since it would be rolled up in a tube.

Can you PM me your offer?

Did you check with lot_lizard at https://deskthority.net/for-sale-f55/model-mf-the-haul-parts-from-harvested-ibm-model-f-s-t14377.html? He has no foams listed, but I would be surprised if there weren't any.

I'll check with lot_lizard, but I'm current working out something with fohat.

The original foam, even in excellent condition, is fairly thin and soft with a "skin" layer on one side.

As it deteriorates, the "skin" becomes sticky and the foam turns into gritty particles. The advantage of re-using original foam is that there is little pressure and re-assembly is probably easier.

A sturdier, thicker new foam will add compression, possibly increasing the springiness, but will also dampen sound and vibration. I would consider that a good thing. It also makes re-assembly harder because you have to use more force to press the plates back together. Using clamps, it is no big deal, but it would be extremely difficult to re-assemble by hand alone with thicker firmer foam.

I can attest to that.  I tried using split straws as a temporary mat to test the functionality of the keyboard, and that little bit of height made re-assembly a pain in the posterior.  I had to use books to distribute pressure evenly so the hooks would align properly, and only a heavy mallet could drive the interlocking plates in place.

In general, you should always test these as soon as you get them to make sure that the controller is good.

Unlike an M where enough bad rivets can render it unusable, even an F with completely deteriorated foam should still function properly.

The disintegrated foam actually got trapped inside the springs, which meant many switches didn't even click when I pressed them.  After cleaning them up, though, all of them click properly.  The unit was marked as untested, so I couldn't really do much if it didn't work.

New item being purchased!

I have an 1987 SSK that fohat bolt-modded I'm considering selling. It's very tight and works perfectly. Bought it from Cindy, but had 2 more SSKs come my way at the same time, so I've been thinking of selling that one off. I can take pictures if you're interested.

Everyone so far thought I was buying a bolt modded SSK.
