Ringing Filco Majestouch-2 Plus Expanding Polyurethane Foam
« on: Tue, 14 June 2011, 12:42:32 »
For those who have been following the other threads, I've been trying to stop my Filco Majestouch-2 from ringing in B♭ every time I press a key.

In one of those threads, someone (I should really circle back and remember who) suggested using expanding insulation foam to fill the gap between the PCB and the metal plate, thus dampening the noise.

So I was at my local Lowe's home improvement store and ran across this stuff...



...with the intention of injecting it into my new $150 keyboard.


...


...





But yes, yes I did.




It was an interesting experience.  This stuff goes absolutely everywhere.

What a mess!



So I got to the office this morning after the foam had cured and...


The ****in thing works!!!  No ****, it actually worked.  I'm typing on it right now.  Apart from a slightly sticky W and F keys, which should loosen up with some lube, everything feels great.  All keys are operational, amazingly.  And the best part?

NO MORE RINGING!!

That being said, for anyone who is as crazy as I am to try such a thing, please learn from the mess I made of my keyboard before you begin.  Some observations:

1)  This stuff REALLY goes everywhere.  Initially I had not removed the keycaps because I never thought it would come through the front of the board, but it did, and went everywhere.  Luckily I have a brand spanking new set of Ducky PBC keys waiting the wings after I get the board cleaned up.

2) Did I mention this stuff goes everywhere?  It's a mess.  Prepare accordingly.

3) You'll need to splice a narrower tube onto the main tube to get it in between the metal plate and the PCB.  I used a narrow drinking straw.

4) Wear gloves.  My hands still have this stuff on them.  The can says the only way to get it off is "mechanically."  Heh.  Appropriate I suppose.

That's all for now, will post more pics when I have her cleaned up and the new keys on.

Oh, and how could I forget...



UPDATE:

Got her all cleaned up and new PBT Keycaps on!

What. the-****.

I remember talking to someone about this on #geekhack a few days ago or a week back.

After seeing the goop on the keys, and knowing what that product is like, well thanks for taking the hit. Now we know what will happen :P

I might make one modification for anyone seriously considering this.

DAP makes a latex-based expanding foam product.  It expands less than the yellow polyurethane foams (even the "window and door" variety) and is easier to clean up even after curing.

In my experience the yellow stuff is NASTY if you get it on anything unintentionally.

I will not be foaming my Filco, but this it the stuff I'm thinking of:

The can says acetone works if it's still tacky.  Otherwise once it's cured, you're hosed.  I probably should have read that part a little more closely before starting.  Heh.  Whatever I can't get off I'll Sharpie black since it's on the inside, shouldn't be visible once the case is on.

Oh I'm not using acetone on the board.  Besides it's cured now anyway, wouldn't do any good.  Except hose the switches.

This btw reduces your chance of a successful RMA considerably.

True.  Although it can't be as bad as trying to return a used electric shaver or something.

Pass.  You probably could have gotten the same results if you just did a few "spots" between the plate and PCB.  Still can't believe you did that.  I've used that stuff for its intended purpose and hated the mess it was.

seriously?  Id rather just deal with the ringing then have my keyboard look like a garbage pail kid.  I've used this stuff plenty of times, sealing holes, insulation yadda yadda and I wouldnt let this stuff within a mile of my keyboard,  I think the only way to remove large amounts is with a sawzaw or dremel.  You got balls lol

Try alpha-foam next time :happy:

It is without hazardous gas and doesn't leave black stains on the skin.

These are my wild formative keyboard years.  Like when Van Gogh drank absinthe and lived with Gauguin.  Well except before they went gay and Gauguin cut Van Gogh's ear off.

The absinthe part is good though.  I recommend Ridge Absinthe

Obviously my xarmor has already a good sound because all the switches were soldered by me, and because the LEDs helps to couple the switches tightly with the pcb and the metal plate.

Still a few keys give me a little ring if I really whack them, but it's livable now, and at the end of the day I'm glad I went down this path of craziness so I can use my Majestouch!

Thanks Solutor.  Better a piccion in hand than two beans in the bush.  Or something.  I had to google piccion.

In Germany it is: "two flies with one flap"

I guess the holes, where the stuff reached the key caps functioned as  blow-off valve

Thanks for the compliment.

For a while there I was thinking you didn't like me.

 
No, I like a lot people used to accuse my of tricking results, of being liar, of stole images and so on.

Shouldn't I ? :becky:

So, I wonder if there are less risky ways of getting the same results....

Say, some high density foam used in hobby applications?  I have some stuff I bought with my gas powered RC car to wrap the receiver with to protect it from vibration.  It comes in sheets but I have no recollection any longer what it was called.  It might work well.   What about thin, closed cell weather stripping in the bottom shell of the case?  It will compress but provide firm support under the board.  Although I guess the problem we're trying to tackle is the gap between the PCB and metal plate so that's no good....  Hmmm

It would be easy for the manufacturer to add dampening during the manufacturing process of course at relatively small cost.  Even on non-ringing boards I would think it would help provide a more solid sound/feel (cue ripster claiming Filcos are perfect as they are and can't possibly be improved upon).

How do you disassamble the keyboard?

Is it possible to pull all key caps and then unmount the metal plate without soldering?
Then you could add rubber foam easily

My understanding is that you would need to desolder all the switches to remove the metal plate.
