Bent can still bend it back, broken pin barulah   
Lubing would almost always be worth it, but, because the switches you have are already in a built keyboard, the motivation to desolder the switches, lube them, then solder back is required. 
Any reason why you need the K-type tip? I have the Hakko Presto, while it's not my main soldering station (since it's not temperature controlled), I got the chisel tip for it which works pretty fine. The Kasadi 936 is a somewhat decent unit for hobbyist, unless you're intending to go pro and offer commissions(where I would say get the Hakko soldering station), I would say the Kasadi is good enough, especially when you pair it with original Hakko tips.

any back lighting on the keyboard? No RGB right?

So I done dumb dumb and bought the Hakko Presto and soldering tips, only to find that these tips do not fit this soldering iron.

I wanted to use a K type tip that is long enough to touch both switch pins at the same time so that you can easily remove them when desoldering. Turns out, there are NO K type tips for the Hakko Presto. 

So what do you guys think?
1. Get the chisel tip for the Hakko Presto. Still way better than my current cheapo soldering iron. Both iron and tip will be Hakko! Spend another RM28. Give up on using a K type tip.
2. Get  this cheapo soldering iron that accepts 936 style K type tips that I already have. Also just another RM28.
3. Get a cheapish soldering station that accepts 936 style K type tips that I already have. Spend another RM85.
4. Don't cheap out and get the real deal. Spend another RM585

Yeah sorry my bad. what about with backlit? any recommendation?

don't quite get the idea, but i put eva foam between top plate and pcb, especially for aluminum top plate.

oh ok got it.

kbd67 mkii (with a top-mount brass plate) that i have doesn't make noise at those contact areas. however this is a good idea haha

Guys,

Anyone played with programmable keyboard before? I'm interested to get a ydmk programmable numpad but wasn't sure about the flexibility of the programming.

The question that I want to ask is when you turn off the number lock, all keys become arrow keys except 5 and 0. Could you program key 5 to become F11 in this mode?

Thanks in advance.

After using lubed gat yellows for a while, I noticed something weird. Sometimes when at night when my room is cold from the AC, some switches get really bad spring sounds on the downstroke. I thought they were just a result of bad lubing or something with the switches but I noticed it comes and goes whenever the room gets cold (it returns to normal the next morning after the AC is off). Wonder if anyone else knows what's causing this or has experience with it. If it's important I lubed the yellows with krytox 205g0 but it was my first lube job so the lubed switches are probably inconsistent with some have thicker lube than others

it looks nice

very nice indeed.

plateless is ok imo, especially for smaller form factors. later i will build some more plateless builds too. the current one is built with lubed 5-pin gat yellow. to me, as long as a metal case is used, and filled with anti-slip mat between pcb and case, pcb flexes will be minimal.

bro, that's a really beautiful build. mad respects. 

Finally some upgrade to me Tecware Phantom Elite TKL

yip .... switch lubing and spring upgrade to some say insane 160g springs.... but i love it.... xD

in addition wanted to add foam on the back of the keyboard and change the stabliser to a different different sorts .... but it not easy as it seems as u need to bend some pin on the board to change the stabliser .... ended up .... let it rest for a while xD

it's a base set with a better price to experience gmk's qualities.

first of all, key shine is a common thing. it just take longer time to build up for pbt compared to abs. (there are people who can make new pbt caps shine in a week or two) even though gmk sets, most probably due to additional surface treatment, builds key shine at a relatively slower rate, eventually they will have that.

key shine is not my concern anymore. their effects on typing experience (e.g. profile, typing feel, sound profile) have take over in terms of priority.
