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:

That's probably very good advice Surly.  Did I mention the yellow stuff goes everywhere and creates a mess?

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.

Oh.

God.

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

A bit extreme, but at least it worked.  Thanks for taking one for the team and you got a pretty nice signature pic if you decide to use it.

Nice, now I can see the mess.

Try alpha-foam next time :happy:

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

Installation foams based on alpha-technology don't stain the skin and can easily be rubbed off again. It is recommended that gloves be worn, but it is not strictly necessary.

That would be the ringing in your ears that never goes away... just give it time, you'll start to notice it after a while.

I underestimated how much this **** expands.  The only way I see removing this crap after it has cured is through sanding.  I should have warned you about that when I read your first post about going to try it out.

I just remove the excess with a utility knife. Or did you mean to clean up surface stains?  Yeah, they're pretty much permanent.

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
