Have to go for Silicone because cork will always deteriorate over time in hot conditions.

This push in bumper in a half inch deep hole. Pushed all the way in, it gives 0.19" lift.

If you want more lift, It has a 7/32" hole running through it. You could run a set screw like the one below into that hole; screw it in .75" and it would increase the lift to 0.44".

Want something taller? Cut two of these to size.

Please tell me I haven't totally missed this in my absence.

Sorry yeh no F62 for you!


Only kidding , as far as i know its still open

I was thinking of something along the lines of the hemispherical synthetic rubber or silicone rubber bumpers or feet that I have seen used with keyboards or aluminum keyboard cases cases. They could either be screw-mounted or self-adhesive.

You haven't totally missed this in your absence.

ok I will look into having two holes where you can add a screwed-on bumper - I agree there is not enough room for it towards the "near side bottom" of the keyboard. So you will be able to add that kind or adhesive bumpers to the bottom.

Any other recommendations besides these?

The factory also set the springs into production and confirmed that they can make the springs to the original IBM tolerance specifications which are about 3x as tight as current Unicomp specifications according to someone I spoke with. This means that the springs will have a slightly more even feel to them like the originals.

Low profile rubber front and back would be my preference. The plate is already curved, so when the back of the keyboard is raised I find I have to angle my hand too far back, and that presents an RSI risk, at least for long-term use. If this were a typical flat Cherry switch keyboard with DSA profile caps, then I might want some extra angle to the keyboard.

The original bumpers were push-in type. Here are a couple of low-profile push in options that might work. Both fit in a 1/4" hole.

Sorry wcass no push in bumpers as that would require additional machining costs. A hole can just be drilled which makes it an option.

The original ones you linked should work - http://www.mcmaster.com/#standard-rubbe ... rs/=zrqrpg Specifically the 9541K2 part. You would need some 8-32 nuts as well.

EDIT : I would be happy with the just the pair of holes myself.

0100010 I hope to make two holes instead of two threaded holes to allow for various bumper options without being limited to one thread size.

Those two push in bumpers work with standard .25" holes.

Good to know! I will try to make the holes 1/4" then.

Do you have any mockups/renders or solid works sketches of the case for the F62? I'm guessing it goes together in two pieces such as the screenshot of the F77 in the OP.

NH

Yes they are nearly exact replicas of the original cases - there are many photos of the kishsaver case insides for reference. The renders are in the OP.

Did anyone confirm if the f62 can fit a solenoid and driver? What about the f77?

There seems to be no answer to the question until we get products. We should check it ourselves. If you are interested in accurate dimentions of both solenoid and solenoid driver, PM me.

Both of these done in WHITE would be superb for our F77s .

The downside of "pushpin" bumpers is that the rubber will eventually petrify into a solid brittle piece and snap off the shaft, hence losing the bumper is easy.

Better stick with adhesives because they're cheaper plus no need to worry about a spare rubber piece floating inside your case like other previous IBMs.

OR you use the ones with the built in bolt and simply use a nut and shake proof washer the other side. That's what i plan to do

Sorry to interrupt, but will the order form open tomorrow as scheduled or postpone some days?

Definitely not tomorrow - it could be another week or two - still waiting on some more things for the factory to do (powdercoating, inner foam, outside foam, spring attachment to the flippers, assembly/test fittings).

okay, thank you. I'm looking forward to it.

I guess we'll wait for a production unit. I have an AT where it could go, but I'll wait till I get both the 62 and the 77 before I decide.

If the case is similar dimensions to the original, then a solenoid and driver should fit fine :

What board is that? Its an F, I can see the xwhatsit controller but not an AT or XT or 122. 107?

And the issue is that the 62 might not have enough space...

That's an F107. From the pics of the F62s I have seen, there should be enough room.
