Gluing Tabs to Plastic Pneumatics
By Bill Maguire

Jeff,  I, too, recently came across a twenty some-odd year old
Universal player console with more than half the plastic arms lying
in the bottom of the piano.  The reason was because the adhesive used
in the factory to attach plastic to plastic had failed.  I used a thick
viscosity cyanoacrylate and the spray that speeds up drying.  My attempt
at using 5-minute epoxy and tape had failed.  A 3M sales rep had
earlier told me he believed that epoxies and cyanoacrylate adhesives
were best in these situations.

The first step was to remove the bottom bellows and the suction box.
Next I collected and sorted out the arms.  I was uncomfortable laying
on my back reattaching these arms.  I applied the glue to the arms,
held the arm in place with one hand and sprayed the accelerator with
the other.  I held each arm in place for about 7-8 seconds until the
adhesive set.  The job took me two hours to complete.  When I was
finished the piano played very well.  The customer was thrilled.

Many say they don't work on this type of "plastic junk."  I have
no bias, I choose any player job I get involved with very carefully.
The customer called me back recently to tune the piano and said the
piano was still playing great!  I'm going to see her next week.
