Marking
Out the Pins
|
|
Now
we have to mark where to cut the pins. Accurate layout at this stage
is vital to creating a joint that will come together easily.
The simplest way to mark out the pins is clamping the pin board in
a vise and laying the tail piece on top of it. The tail board should
be propped up at the end so it stays level on the pin board. You should
use a clamp to ensure that the board is correctly aligned and square.
Check your markings so the insides are all inside and the outsides
are all outside.
Most important: line up the boards, not at the ends, but so that the
scribe line on the tail is just at the inside face. Use a knife to
mark carefully where the pins should be. |

Mark
the Waste
|
|
Previously
we cut out the tails by removing the waste where the pins would go.
This time we do the opposite. Use a sharp pencil in the knife lines
to help make the lines easier to see. We also compulsively mark the
waste with an "X." |
|
Sawing
the Pins
|
|
If
we were hand sawing, we would then scribe downward to show the cut
lines. We don't have to do that with the AngleMag. Clamp the pin piece
in the AngleMag just as we did for the tails. As before, make sure
it is clamped solid and square. |
|
The
only trick here is to double check that we are cutting on the waste
side of the scribed line. We just want to graze the scribe line. Put
the saw on the guide and see where it contacts the wood. Slightly
loosen the top screws on the guide and position the saw correctly.
Then retighten the screws. Of course, to do opposing saw cuts just
loosen the screws enough so that you can rotate the guide 180 degrees
around. |

Chopping
Out the Pins
|
|
With
all the pins sawn out, it's time to chop the waste. Chop out the pins
the same way we did the tails. Make sure you are really chopping the
waste. As with the tails, place your chisel just before the scribe
line and drive the chisel in forcing it down and back towards the
scribe line. Work from both sides. Some people saw the waste out with
a coping saw and then chop just a little. This works too, but for
narrow pins and tails like this chopping works fine. |
