On raised panel cabinet doors, theoretically, should the allowed
expansion clearance in the stiles vary with the width of the raised
panel that occupies the area between them? Is their a rule of thumb to
determine this.

Sure 1/8" per foot across the grain per 5% change in Moisture Content.

One reason for finishing the backs of things as many coats as the front is
to keep the whole thing from taking up moisture so rapidly. Less vulnerable
to two weeks of high humidity.

I leave enough clearance to allow for the addition of space balls on each
side with out completely crushing them during assembly.

"Theoretically", it depends upon the wood species, the way it was sawn from
the log, the size and time of the year you made the panel, the part of the
world you made it in, and anticipated seasonal moisture content where the
piece will reside.

Just so happens that there is an excellent article in 12/06 FWW, on the news
stands now, and entitled "Stop Guessing at Wood Movement", p78, which deals
very nicely with your question.

I've never used them. Think I'll give them a try. I notice Rockler
sells a hundred pack or you can get a 1000 minimum direct. Where do
you get yours?

Do they work on glass panels with a quarter round backer? No
expansion problems but to hold the glass firm and eliminate rattle?
