Buckling Spring Numpad - possible?

Hey guys,
As i get my SSK in a few weeks i thought about building my own buckling spring numpad from a functional full size Model M.
Has anyone done something like this already? I saw the thread where somebody made his own HHKB Model M, so i thought it will be possible to make a buckling spring numpad as well.
There will be soldering required i think, but thats no problem in any way.
Best regards,
David

Look into hasu's "Happy Buckling Spring Board" which is the project you mentioned. Why in fact you could chop a full sized M into a keypad and an SSK. But you'll be short one side of a case and one controller board.
If you just want to turn an M into a keypad: you'll need to do a fair amount of work to get the traces correct on the membranes. Copper tape is a better solution here than solder as the soldering iron will melt the membrane.

An actual IBM numpad exists, although it was a pretty rare accessory and you would have to be very lucky to find one.

Well that seems like a kind of low price to me doesn't it?
15000 Yen =~ 115€?
But yeah, an original numpad would be even better.

Btw, ramnes, I know you were unhappy about that being posted on GH.
Just to let you know.. It didn't go to a GHer

Couldn't you just buy a regular membrane numpad (+controller) and substitute the membrane in the Ms numpad?
Is this a really bad idea?

I would love to have a BS numpad. That Japanese one is super rare, so if someone could make new ones under that cost that'd be great.

Do it.

There was also a Model F "numpad" that was meant to be paired with an unsaver. There's a photo of one hidden in plain sight somewhere around here. I'll repost the photos if I find them.
Edit: Photos
here.

The older LPFK variant maybe? That one was Cherry M8, and not buckling spring.

I've only seen
this LPFK and the similar black version. The keypad I saw was different - it looked as if some had cut off the numpad area of an F122 and was using it standalone (the keys were arranged in a square 5x5 matrix).

Was doing some box sorting today, so thought I'd take a few quick terrible phone pics of it:
