In response to Jeff Bridges' posting, there a few methods for dealing
with this problem, most of them don't work very well. This is a very
common problem in player actions with double valves like Standard and
Autoplayer. The best way I have found is as follows:
First, you will need to use a drill press for this, for the drilling
process must be accurate and straight. If the screw holes are directly
between or near air lines (like the lines on the secondary pouch
board), you need to drive a 3/4 inch brass tubing into both air lines
so they will not split out, if they are not already.
Drill out the depth of the old screw hole with a 1/8 inch bit. Take a
toothpick and coat the inside of the hole with slow setting (8 hour)
epoxy. Tap in a piece of 1/8 inch hardwood dowel, trim it as flush as
you can, then wipe away all the epoxy residue and let sit over night.
Next day, make a small hand-held sanding block with paper no coarser
than 120 grit. Carefully sand the dowel points down flush. With a
small punch or nail tap a little center mark for re-drilling. Use a
5/64 - 3/32 bit if it's a #6 screw. This is a lot more work but is
much more reliable than jamming toothpicks and/or glue in rotted screw
An important thing here is to never overtighten screws. This is where
proper gasketing leather is important. Gasketing must be resilient
enough to accommodate minor shrinking and swelling of the wood
sections. Screws should be tightened down firm but not tight.
