There is 3 plastics JWK’s mystery meat stems (P3s) could be made out of. I was cleaning the lube off of some Cobalt POM switches I harvested. I noticed the stems were floating on the mixture of Vertrel XF & water I was using, while regular POM stems sunk. So on a quick search of what plastics floated I found this blerb.
Which plastics will float in freshwater?
The three that float in water are less than 1.00 g/mL and these are: HDPE, LDPE, and PP. See the chart on densities for the actual numbers. Plastics will vary in density when they are manufactured so there is a range of densities for each kind of plastic. Pure metals have an exact density and not a range.
I wonder which of three or what blend of them they are using?
Your contribution to keeb science is to be commended. I just hope the size tolerances are better than UHMWPE stems – I just bought a bag of them from Prevail to use in some Gat CJ housings, and I’d hate to play the “will my kecap stay on” game like the other stems.
Apparently my work doesnt block the discord web version on my work laptop. But I joked with my manager that if im gonna use it im gonna suffer on the mobile version and not risk my job (idk if using it during work would get me in trouble or not)
I actually managed to lube 25 switches yesterday which, lately, is a massive achievement for me. I used to bag lube my springs with 105 but lately I’ve switched to donut dipping the base with something heavier (Gazzew’s Blend #7 in this case). I was initially skeptical that this would work as well for ping and noise reduction but the more I do it, the more convinced I become.
When I have the time, I’d like to go a side-by-side with an awful spring to A/B the donut method, bag lubing, and a control.
Separately: apparently my wife thinks that one red switch and one green switch on our Christmas tree was a dumb ornament idea but I stand by my festive choices.
Today I learned to always check how much lube you have before fully opening everything… Got maybe 20 switches done and my operation has been temporarily halted.
I think a decent meter is the most overlooked troubleshooting tool in this hobby. So, so, so helpful.
Also, for the current portion of the video, if you intend to do anything beyond keyboarding it might be worth getting a clamp meter so you don’t have to break the circuit to test it.
You really need a delay for the “hold” part of the hold/tap mechanism handling, otherwise it’s going to be a hell when typing fast and doing rollovers. Especially important for home-row mods.
