PVC-E glue/keytops

[David Love]

"Goof Off" takes it off very quickly and easily and doesn't seem to mar
the keytops, but test first.  

BTW I built a key clamping jig out of a bunch of trap springs.  It works
very well and is very quick, cheap and easy to build.  I'll send a photo
if anyone is interested.

OK,

I installed my first set with PVC-E glue instead of spray contact
cement.    I tried brushing it on one key and decided to try the roller.
I got a little 3 inch roller/plastic paint holder combo at my hardware
store.   The holder is as big as the roller.   Of course it all can be
washed up with water and re-used.   Just like you are painting a wall
with a roller you pour a little glue into the holder and roll the roller
in it back and forth to coat it evenly.   3 keys at a time at first
eventually 2 sets of 3 before attaching the keytop.   the roller put on
a very thin coat of glue...my only concern is if I have enough glue?
Not nearly as much wiggling when a thin coat of glue is on the keytop.
I think painting it on may? put more glue than you need? and thus the
extra wiggling of the keytop.   

Boy you need to be extremely careful to use CLEAN wet paper towels or
such and toss every few keys.   I spent more time trying to clean the
keytops of glue residue.   Finally, I tried using the clean, wet paper
towel to rub down on the keytop for the pressure and tossing the towel
every key.   That seemed the best.    

I LOVE THIS GLUE...except it's propensity to sneak onto the keytop...It
went as fast as my spray glue.   With the spray glue I could clean after
the entire job with paint thinner to remove overspray, glue on fingers
etc....

I'd like to see others try the roller and give some feedback.

PS   I clamped with Bill Spurlocks key clamps just to make sure the
keytops didn't rise.   Although, I didn't see any doing that...well,
maybe one a tiny bit...
