Hello again everyone! I've recently acquired a used Realforce 87u 45g(uniform) for work. The bottom two rows on Topre profile are really angled and it is causing pain in my right thumb. I'm used to OEM(Filco/CM/etc) profile and on my NovaTouch with stock keycaps I don't experience this.
I did a forum search and it seems some people flipped their spacebar around. This seemed to help people who rest their wrists on the table the most. I tried flipping the spacebar but it doesn't work for me because I hit the spacebar with the side of thumb, parallel to the table and not at angle. When I type, my wrists are 1 inch off the table.
Right now I'm resorting to typing with my wrists 2 inches off the table so that my thumb is angled like the spacebar.
Is the Topre profile exposing my bad typing form, or do I just need time for my thumb to get used to the sharp edge?
I think you should flip the spacebar and give yourself more time.
I hit the space bar as you do, but a little bit lower, so when the space bar is flipped the tip of my thumb hits it on the flat portion. It's very comfortable.
A flipped space bar is aesthetically very ugly, and at first I did not want to keep it that way. But it's so comfortable that it's worth it.
Give yourself more time and I believe you can adapt to a flipped space bar. This will solve the problem of hitting the space bar on the angle, which is indeed painful after a while.
Something else you can do (and I did it) is to
remove the spring located under the space bar. It will be easier to press (it will have the same "weight" as the other keys).
