The pipes you speak of should never be glued. I have worked on some
that were. They were a real pain. They can be re fit to the toe board
by cutting a strip of typing paper to wrap around the toe when you
wedge the pipe back into its hole. It should not be extremely tight,
but just tight enough not to tilt or pop out.
If your pipes are blowing out of the holes you are not getting the true
pipe voicing. You might notice that those pipes are softer or do not
speak quite right. The seal must be right or the pipe does not sound
right. If someone has drilled out the toe board or sanded the toes,
you may have to line the holes with felt or veneer.
You never know what kind of work has been done on instruments before
you get them. You might have an instrument running on too much wind.
You should adjust that and see at what pressure the pipes sound best.
They should all speak quickly and with no overblowing to other pitches.
Someone might have cranked up the pressure to carry farther. Unless
you are willing to hire a true pipe voicer to revoice, some might call
it butchering, the original pipework, you should find the pressure that
the pipes were originally voiced on.
Hope this helps.
