| ER...that brings back memories.
I have what is called a "Pink Pet" ... I thought it was equivalent to 
the old "Pink Pearl"  erasers my pop used as a a CPA so many years ago.
But, now y'all got me worried.
I just looked, and the "ink eraser" I mentioned is made of pliable soft 
"rubber"  manufactured by Helix and purchased at the local 
Office-Staples-Depot-Max, and may not be a true "ink eraser" after all, 
but still, Bob's point remains - it may not be the best tool for the 
job.  Who knows what it is really made of?  It all seemed so simple 
until now!
This is what it really is:

I am a real fan of using the right tool for the job, so this is a 
material inquiry for me as I am building more and more kits as I go 
along.   In fact, I am kinda bursting with pride because some guy 
offered me $75 for my the little microphone attenuator and adapter 
project I invented.  While tempting, I would not let him do that, as it 
IS amateur radio, but it IS flattering nonetheless.
Thanks for the uptake guys.
