Routers and Tearout
And I really should have known better. Really. This is starting to read like a "Mistakes not to make when building a boat." - Actually I may use that as a title if I ever write a book. I certainly won't be short of material.
I forgot that Routers like to cut the grain, but they really like to lift the grain. So the bottom peice here has nice big lumps missing.
When you find that the direction of spin of the blade will lift the grain - see diagram opposite.
Flip the thing over so that the as the blade of the router rotates, it cuts the grain, rather than trying to lift it.
Of course the really annoying thing is that I knew this, I really did. In my hurry to finish the frame, I forgot. And then when cutting seemed not to be working quite right, rather than take five and put my brain back into gear, I pressed ahead and messed up.
The damage is done to the part of the frame that sits on the keel.
If you can't be a good example, be a dire warning.
