Squeaky Pedal

[jolly roger]

Hi Tom,
              A couple of fixes.
When the the support rod squeeks against the pedal box.
1. Cut a slim piece of double sided tape,  and one wrap around the end of
the rod.
2. Re loccate the upper support rod bracket, about 1/8"

When the upright member squeeks against the box.
 
Remove pedals,  Take a block of wood and hammer the pieces tightly together.
Apply thin CA glue to to the end grain of the dowel and glue joint, you
will be suprised how fast it will disappear.  Spray lots of accelerator
around the the finish of the the box and upright, so it will flash the CA
glue if it wicks right thro'.
Fill the cavity area of the shim with thick CA glue.   May as well do all 4
dowel areas whilst you are at it.

Hope this helps.
Roger
