Dave, before using your one piece keel you might want to check your frames to ensure the upper futtocks are long enough. If you simply traced them for laser cutting from the original plans its possible that they may not. I can't remember from what I did and am not home to check for you. I'm assuming of course, from your explanation that the keel will be the same thickness fore and aft. If I'm incorrect, disregard this.
maybe cool blocks will work blade flutters because the guides are not adjustedHi Dave getting desperate, trying to find guide bearings for my band saw, contacted Carter, they said they do not make the guide bearings for a 9 inch table top band saw, the blade is flutering badly have tried to retension but to no avail, SORRY FOR HIJACKING THIS THREAD.
