At long last my mods are (mostly) done.
Attached Image

All switches spring swapped to 67g, bag lubed with Krytox 105. Sliders lubed with Krytox 205. Filmed with TX films.
Foam layer between plate and PCB, foam inside bottom case underneath PCB, top case spray painted.
Stab housings lubed with Krytox 205, wires checked for straightness, lubed with superlube. Attached to plate with PTFE tape to eliminate wobble. PCB band aid modded with cloth band aid and lathered in Superlube.

It is a dream to type on. Sounds wonderful. But the keyboard gods decided to play a cruel joke....

Despite my care during desoldering and soldering, I even did a full tweezer test after desoldering...1 key is not working properly. Luckily it is about the only key(yes I have used Pause/Break before) I don't ever remember using, right alt.

Switch hitter registers one press and TWO ups.

Keyboard tester registers right alt as left ctrl, left alt, right alt, and right ctrl simultaneously.

Switch is fine. Desoldered and tested with multimeter. Same behaviour on both test software with switch removed and using tweezers. If anyone has any suggestions, I might consider fixing it, but for now I'm going to try not to lose my cool and just live with it.

Anyway...in case anyone is curious about the PTFE mod.
Attached Image

Hohoooo, I thought I was so clever. Never seen anyone else do this. Most people stick more band aid pieces in the gap. I tried that and was not satisfied with the stab wobble. I wrapped some PTFE tape around the housing and voila! No more wobble. I invented a new mod!

Not so fast...Side effect of the way I wrapped the tape is that the stabs don't properly latch onto the plate.... So whenever I pull out a stabilized key, the stabs have a tendency to pop up a bit.

Well you just pop them back in before putting the keycap back on.
Attached Image

No big deal. Highly unlikely to pop up during use since you are pressing down on it. Still trying to stay cool. I have a nicely tuned keyboard. Sounds awesome. Let's not dwell on the imperfections ok.

come on you know it's a pretty good experience smile.gif

for the weird key registering issue, i had such incidents when:
1. i over-tightened screws onto the case (tray-mount, so it might cause pressure to the pcb); or
2. when there is too much pressure on pcb from the foams, usually from bottom case; or
3. the pcb had direct contact to metal, and caused short circuit.

as for the stabilizer mod, usually i just put a layer of ptfe tape on the side where the lock is located. the thickness of ptfe tape is 0.25mm. usually it will not move anymore after application. for stabilizer tuning, it's still about making sure the wire is straight, with both tips lubed and pointing at the same angle, and the housings and sliders are lubed.

Typing experience or modding experience tongue.gif
The typing sure as hell is awesome. It's fully functional even without right alt. That's what keeping me sane and happy with my keeb.

Yeah my plate-foam-PCB sandwich is definitely very tight. I even purposely retightened a few switches by pushing it in while melting the solder joints. Not sure where or how I can release the pressure. Maybe just melt all/most joints and let the pressure push the switch to whatever level. I worry about inconsistent feel and height though.

hi there, am new here with zero knowledge on mechanical keyboards.

Is there any shops in KL people can recommend to test out the range of keyboards switches to know what suits me best?

Can someone recommend me a few budget beginner full-size (with numpad) keyboard to start of with?
perhaps a cheap one, and another slightly pricier one that you think its worth to spend a little more on.
usage for daily work comp, not much a gamer, just casual one so no need super good one, most importantly a nice typing experience

I can wholeheartedly recommend the IKBC CD108 non BT edition for just RM279
https://s.lazada.com.my/s.bIMtl

But while browsing Lazada for the link I saw this.
https://s.lazada.com.my/s.bIN3X

Slightly higher end model. Single colour LED backlight. On pre-order for RM1 cheaper.

my best guess is that it's probably the area around the bottom row. (i.e., row 4 and bottom row)

Well, tried it and didn't work. Loosened all along the 4 edges and 2 bottom rows. Then on a hunch I removed both Ctrls and LAlt to see if RAlt will behave. No joy.

Tightened everything back up again, and now there's a slight rattle on 1 side of space bar. Then realised I can't remove the stab even with the switch removed because of the foam. Sigh...

My wallet is scared about what I'm going to do tomorrow night when a few units of kbd19x are going on sale.

this has something to do with how they are wired. not sure if you can find the correct matrix that got affected. imo the better bet is to desolder all switches and start over.

i do leave space for a chance to take off plate-mount stabilizers, because i usually screw them up.

to make things easier for self repairs, use true 63/38 solder wires like kester or mechanic, and a good desoldering pump. it helps me a lot especially during the switch desoldering process.
*
I'm using a generic 63/37. Don't know why it's actually harder to suck up than the factory lead free solder. Maybe it's my soldering technique.

if possible, use true 63/37. it's supposed to be much easier to suck it up. i use 350c, touch the joint with tinned soldering iron for a second or two, then release the primed desoldering pump. just did it just now to fix my backspace on this 60%.
*
What defines a 'true' 63/37? I'm using this:
RM6.00 | 50G 100G 63/37 60/40 99.3 Soldering Lead Wire Solder Lead Free 0.3MM 0.8MM 1.0MM Rosin Core Flux Tin Copper Sn Pb Cu | https://s.lazada.com.my/s.bsdbi

I have my cheapo desoldering iron that I reviewed in the last thread. While it does get hot enough to melt my 63/37 joints, it can't suck it cleanly like it did the lead free solder. The pump action is also slow like somehow my solder/soldering technique created an air tight seal that the factory did not. Really don't know how to explain it better.

Edit: oh I'm also not using a soldering station, so no temp settings here. Still using my Hakko Presto with Hakko chisel tip.

the true 63/37 solder is supposed to be relatively easier to solder and desolder, compared to 60/40, or lead free solder.

the problem is that some brands, like the one you're using, labelled everything as 63/37, but its actual content is determined by model number, especially the variant of the same model number. (model a, b-1, etc.) to avoid such confusions, just grab something like mechanic hx-t100. you can find it at shopee.

imo the slow pump action might mean it's cloaked. just clean up the desoldering pump regularly. soldering irons with temperature control are more like convenience. i don't think it's your issue.

edit:

for now i'm using kester (flux 245; core 58; 0.6mm). it flows very nicely. i learned to feed solder at a certain length for each joint to avoid overflowing.
*
Pump is not clogged, it works fine in the air and also if I put the mouth flat on a clear piece of PCB (while cold). But put it in a 63/37 solder joint and melt it and it becomes slow. Did not happen with the lead free solder. I wish I had another prebuilt board with lead free solder joints to confirm this but I don't.

Won't help me with what I've already built but if I do manage to get one of the few units of KBD19X going on sale tonight (and if my wallet doesn't chicken out), I'll invest in a spool of Kester and maybe even a soldering station. Not going to leave anything to chance on a more expensive board.

Anyway, have been practicing on my Cospad today. Desoldering iron still not working on my own soldered joints, but I've settled on a reasonable technique. 1 pump with normal desoldering pump to get the bulk of the solder out, followed by wick dipped in solder paste (I honestly don't know whether or not this is the same as flux, opinions on the net differ).

Not too bad. Clear holes but lots of flux staining.

I just can't do it. Sorry. Chickened out.

Just a few days ago I saw someone selling KBD19X built with Zilents on mechmarket for only USD350.

A brand new one, kit only, is costing me USD310? Naaa. Even though in my heart I know I'm buying to use and not to flip, it just doesn't feel good to me.

Edit. P.s. sale started at 10pm and there's like 23 units left, so if you are reading this shortly after I posted, you might still be able to get it.

1800 and mini USB, it's still a compromise for me. If it was a full size, USB C, alu in grey or blue, I wouldn't hesitate even at that price.

I balked at having to pay so much for a compromise. But it's not often there is a bigger custom board available so unless my holy grail board appears, I will always wonder if I'm going to regret not buying.


And an update on my modded IKBC F108:

First day working after finished rebuilding it, using it on my work MacBook...and keyboard tester is all OK...huh? Unplugged it and plugged it back in to my kid's Windows PC, still failing both keyboard tester and switch hitter. Since I only tested it on a Mac before, it's possible that it was actually DOA and not anything that I did.

I feel relieved and pissed off at the same time. rolleyes.gif

you can start with switch and stabilizer tuning. there are plenty of guides at youtube.
yes, try this one. so far i have done this for my gk64 and z70ultra. it's really effective.

later i will try to do the rama's shrink tube mod also, https://www.youtube.com/watch?v=r3da8CMV2_M
it's a mod by our friend at mymkb. no this is to minimize the tinkling sound when wire tips hit the upper part of the stem hole when you tap on the edges of space bar. this sound is not obvious for shorter modifier keys, but they are there too, if the wire tips are not tuned properly.

another similar mod is is from rama (video above).
*
Interesting...thanks!

There's a link on the YouTube vid btw.
https://rama.works/guides#/silencing-stabilisers/

The mymkb mod deals with the tips only, but the rama mod is after the tips but before the bend, correct?

Pretty soon there won't be a single surface that doesn't have a mod. Lol.

P.s. my switch stickers finally arrived. And my V2 C3 stabs GB. smile.gif

Just saw this foam. Genius! 3.5mm according to the Taobao page. The 3 types of modules can cover everything except for stabilized keys.

Edit: Also says this on their Taobao page (from Google Translate). "This product has applied for a patent, please do not counterfeit, counterfeiting will be investigated!" Lol

Tried my hand at balancing stab wires from the stock plate mount stabs on the tecware phantom elite. Although it helped a bit but the longer keys (spacebar in particular) still sinks a little and makes a tapping sound when softly tapping on either side. I assume it's because I'm not balancing the wires properly but I wanted to know if it's worth it to swap out the stock stabs for something else. Seems pretty hard to find any plate mount stabs in the first place with the cherry ones being sold out almost everywhere leaving only OEM brands. If only the phantom elite pcb accepts screw-in or pcb mount stabs...
*
Yeah, I was searching for original cherry plate mount stabs as well before I assembled my board. Only place in stock I saw was Zeal.

You can also try looking for Durgod Nebula K320.

If you don't need RGB but just backlit, the Durgod Corona K320 would be slightly cheaper.

i posted here time to time with another account. Now change account because privacy invaded matter  laugh.gif

anyway i just built this keyboard
user posted image'
gateron brown with springs changed to 55g, switch film added, springs lubed with 104, stabs band aid+clip, 4mm eva foam between pcb/backplate and everything else lubed with 205.

A lot of building processes which I thought was easy, turned up to be not.  tongue.gif I made tons of mistakes and took very long time messing around with the keyboard  biggrin.gif . Every thing is quite fun for me except the lubing part.  ranting.gif

The major mistakes i did were
- soldering quite a number of switches without the switches fully touching the PCB. Luckily i realized something was wrong before i proceeded to solder more switches. I learnt that it is very difficult to push the switches 'into' the pcb. My fingers are hurt now because of it.  biggrin.gif

-cutting the foam to put between plate and pcb. I ended up giving up and put nothing in between the plate and pcb. Have to be very precise in cutting the foam to leave enough space for each switch and stabilizers, but I failed miserably. All the shapes i drew by aligning the plate to the foam were all incorrect due to the stretchy nature of the eva foam and also not drawing exactly at the edges using pen. I wasted most of my time here.  biggrin.gif  tongue.gif Here is the showcase of my masterpiece. 

I feel that Gat browns lubed are indeed overly light for me as oppose to be using MX Blues which I think is heavy. Might have to change all the switches to heavier ones in the future bangwall.gif  shakehead.gif

I had bought some 3mm LED bulbs, but havent soldered them yet. The led holes are at the lower part of the switches. I tested the leds through the holes with a lithium bat, but the effect is like very disappointing. All the letters/symbols are floating towards upper part of a key cap. I think last time someone asked the same question, but now how ah? I didn't know because I see the mx switches in razer mkb are all upside down one. XD

Also, the taihao keycaps im using dont have R0 1U Ctrl, FN, Alt and numpad 0 & R4 Delete, End and Page Down. doh.gif I wasn't thinking so thoroughly before this. I think most of the keycaps set doesnt have these, am i right? I read some where people saying have to buy the ortholinear keycap set of a GB/preorder lol. Can any1 give me advice regarding this?

Nice! YMDK 96?

A pity about the foam though. Although it doesn't look too bad IMO, what did not fit?

How many times would you dare to desolder a board? What's a safe limit in your opinion?

I just lifted a pad in my cospad the other day....I think I was desoldering it for the 3rd time.

The MF108 is their top of the line and slightly better quality than the Ducky Shine 7 (Full alu top and bottom vs zinc top and plastic bottom)

Corsair at that price only has alu top and plastic bottom.

Plus IKBC is highly regarded (though less famous) by r/mk.

Other good brands I would recommend are Leopold and Durgod.
