Gang -
The direction of coping saw teeth would seem to be a straight forward issue, but apparently not so.
Page 49 of the Nov04 "Family Hanydman" in "Coping isn't as hard as it looks" says "Make sure the teeth in your coping saw point TOWARD the handle. That way, the blade will cut smoothly on the pull stroke."
Page 63 of the Dec04 "Workbench" in "Coping Saw Technique" says "For a chip-free cut, you'll want to mount the blade so the teeth point AWAY from the handle of the saw. It also helps to make relief cuts, which allow the waste blocks to fall free."
My inference is that this can't then be a very big deal.
What say ye that have coped with far more than me ;-)
