    G10 is not the easiest material to machine. To do it right, you need diamond mills and constant-flow coolant; neither of which I have. So I'm experimenting with different materials. Wood seems to be the best option. It's cheap, readily available and easy to machine. I tried some pine first, but it just didn't yield the consistency needed. I tried some maple and while better, it still wasn't perfect. Walnut seemed to give the best results, but that was the extent of my hardwood inventory too.

    I'll dig around and see what else I can find, maybe rock hard maple like they use for guitar necks would be the ticket. That stuff machines really well.

    Went to the pond today, but spent too much time with other projects to test this one. Next time out, I'll run it first.

    Went to the pond today and ran the cat. It wants to stick the bow in the water until it gets going, then it's insanely fast with that high-pitched scream that accompanies the REALLY FAST boats you see. It definitely needs some stakes to get the bow out of the water sooner and easier. There's just too much laminar flow trying to keep it stuck to the surface. I'll remove the taped-on cave-man spray rails and build a real set of strakes and spray rails for it. That should make it one frighteningly fast beast.
