If the relief cut is not large enough, you may find you've left a nub in the corner. Just turn the blade around, come back and clean out the corner.
If you do end up with a nub, you can use the blade to trim it off.
The Cottage Clock-Cutting the Fretwork
Now, lets finish off the spiral.
| To start on the outside of the spiral, we need to cut a relief cut. This is done very similar to the angle cuts we've already done. |

Once the relief cut is done, we can turn the blade and
get ready to start the cut. Since this turn is almost a right angle,
it's much easier to get the blade to bite into the wood. You
shouldn't need much side pressure, if any.

Once again, cut around the outside of the spiral,
slowing down and easing into the previous kerf. The goal is to stop the
saw before the old kerf can pull the blade over. If you look the
blade is entering at almost a 90 degree angle, so this is not much of a
problem for this cut. The tighter the angle, the more careful you
have to be to prevent a nub.

We've now finished the spiral. Discard the scraps, and pick out your next hole! |
On the next page we'll do a hole with points.
