  1. Devon is right on about using a very very sharp iron (blade) and light cut. You can plane just about anything like that. I have a low angle stanley block plane that works great. The only catch is you have to keep it sharp. This is an art in itself and is worth learning.

    I usually hone my iron after ~10 min of constant use. You can tell the iron is dull when set for a fine cut, it won't shave anything off. Then you expose some more blade and POW... tearout (or the blade will 'skip' across the wood). You want to plane the wood so you can see through the shavings when held up to light.

    Good luck, Hope this helps.

  2. check out thornguitars.com. Go to the discussion forum, there was a thread a while back on the shopbot.

    Ron Thorn builds his own cnc machines, so he knows what he's talking about. His opinion of the shopbot is that it is pretty much crap. Cheap parts and large tolerances. Check the thread for more in depth info. Sorry, no link.

  3. "Our thought was that different wood types don't actually enhance certain frequencies; rather, they damp the ones you don't hear."

    Yeah, that is exactly right. The wood cannot enhance frequencies, as it does not supply energy to the system. Wood is passive in this sense.

    Kinda like why you need batteries for active pickups, to put energy into the system and enhance certain frequencies.

  4. sounds like a cool project!!

    in one of my eng classes we determined the speed of sound in a steel bar. the details of the experiment escape me at the moment, but an accelerometer was attached to one end of the bar. the bar was then tapped very very very lightly.

    i think if you did something similar, but maybe tapped the wood harder to get a whole range of frequencies you'd get some neat results.

    i think the mount for the piece of wood would be key though. depending where you clamped it you'd get different responses.

    keep us posted.

  5. my $0.02, stay away from the router. shaping the neck by hand forces you to learn what feels good and what doesn't. it is also lots of fun.

    i have used (with good success) a plain half round bastard file and a half round autobody file for the rough shaping. the autobody files are kinda tough to find (check eastwood.com), but they work great. better (smoother cutting) than most rasps i've used.

  6. skibum,

    this won't help you with your search, but i live about a half hour from west penn hardwoods. very cool place. several months ago, they had some HIGHLY figured imbuia that was just spectacular (but not cheap). you may want to email them and ask for a pic if they have any left. i really can't explain the figure too well. all the boards i saw were different, but all cool. it smelled nice too.
