                     I did a test this afternoon as I was working on a 
bridge. I took a piece of maple with 27 grains an inch and one that had 6. I 
drilled a whole in each for a no. 8 bridge pin. It took about twice the force 
of the hammer to drive the pin in the tight grain piece. I then drove each 
pin back and forth twice and the tight grain piece stayed much tighter than 
the other. 
  As Ron said the other day if you use the wider grain stuff it compresses 
more, and drilling a smaller hole will obviously be required.
   I personally like maple. I've learned to notch it and read it so I'll be 
looking for my own sources and resaw my own as I once did. Or maybe we can 
get some Chinese/asian firm to make the laminated cap stuff and sell it to us 
all reeaall cheap.
