Adding a 10g spring to a topre 45 keyboard

So I’m back to crazy keyboard mods. I have a topre Novatouch that is 45 grams actuation force. It’s nice but it’s definitely lighter and a little less “thock” than a 45 gram uniform Realforce. So I decided I’d try to add a 10g spring. The actuation on a topre board depends on the rubber dome and not on the spring force like with cherry compatible switches so adding an external spring will change tactility and feedback, not just add force. I knew that the feel would be slightly different but… I’m not offended by it in the least. When you hit a topre key you usually face a little bit of resistance high up on the keystroke and then, after a tactile bump, the rest of the travel goes down real fast until you hear the “thock” sound (ok, I don’t, not really because I’ve also silence-modded this baby). With the external spring you need more strength (should be around 55gram actuation ideally) but the weird thing is that instead of the initial resistance-bump-drop-to-the-bottom thing there now is more of a uniform resistance, slighter bump and the key jumps back up. This is much more similar to an IBM Model M but without the sound or (if you exclude the tactile feedback) to a cherry mx black old school. So it’s a completely different beast. I like it, but it’s not topre any more. It’s a ModelM/Topre/MX Black hybrid and (as fatigued as my fingers are at the end of the day) I LOVE IT.
