Thanks, Mark.

And how has the Heat n Bond held up?

>> Thanks to everyone who dropped by the Dampp-Chaser booth in KC to see our
>> install demonstration.
>>
>> Roger asked for feedback regarding the "heat and bond method," so here's
>> some of my own, from an install completed this just twenty minutes ago:
>>
>>
>>
>> KG-3c / Church Piano / G6PS-50 system plus 2-25w bars / still swings 25
>> cents @B2 seasonally!
>>
>> Arrived in the sanctuary at 11:15, finished and submitted my bill at
>> 11:50.
>>
>> Thirty-five minutes to fit and trim the undercover... perhaps sooner, if
>> the
>> caretaker had taken my hint(s).
>>
>> Pre-stapled the bonding-tape around the rim for convenience. (feeling a
>> bit
>> shaking today, too much coffee!)
>>
>> Made sure to use the Heat n Bond product marked "SUPER" or "SUPER 
>> WEIGHT."
>>
>> Started fitting/ironing at the corner of the bass rim and belly rail, to
>> take advantage of two straight sides.
>>
>> Saved loads of time, as only the treble and tail sides required trimming.
>>
>> Second pass all the way around with the warm iron, just to be sure.
>>
>> Done!
>>
>> Notes for next time:
>>
>> 1.) Bring fleuro-trouble light, makes it easier to see where the bonding
>> is
>> and where to trim.
>>
>> 2.) A dull knife isn't a knife!
>>
>> 3.) Send the caretaker on a long errand while I'm working! ;>)
