and then repeat for the top right corner.<br />

Remember:<br />

1. Put them together and flip the front board. and cut both<br />

rows together.<br />

2. Cartwheel them both together and cut the other two. and<br />

that’s the Tails done.<br />

Making the Test Pins<br />

DO NOT FORGET TO DO THIS...<br />

...before you leave the tails, take a piece of good scrap a little<br />

wider than the width of two sockets and cam it in place under<br />

the bit which is brought forward to cutting position (off). Push<br />

the router away, and squeeze the scrap up a fraction. Cam it<br />

in again, and switch on. Bring the router forward so that the bit<br />

cuts a shallow groove in the top of the scrap. Cut the first pin<br />

position, and then the second making two shallow grooves.<br />

It gives you both the bottom dimension and positions of the<br />

first two tails.<br />

Keep the Test Stick in place and...<br />

Making the pins<br />

...change the dovetail bit for a straight bit. <strong>The</strong> larger the better<br />

(less break-out), but it must fit easily between the pins, and<br />

also be right for the Template. We will check that next.<br />

You now use the wedge shaped Islands on the template, Raise<br />

the Pin.<br />

Now track the Bit to the back edge of the test stick on the right<br />

hand side of the groove so that the left blade is just touching<br />

the right hand edge of the groove.<br />

Unlock the Pin Plate (Pin down) and move it up so that the Pin<br />

comes up against the wedge. Lock the Drop Pin Plate.<br />

Track the Bit to the other side of the groove and align the right<br />

hand blade with the left edge of the groove.<br />

<strong>The</strong> Pin should come up and hit the wedge on the left just as<br />

it did on the right-hand side.<br />

If the Pin runs off the top end of the wedge, when the Bit<br />

is placed, the bit is too small to hit the wedge so change the<br />

bit for a larger diameter straight bit and start the test again:<br />

loosen the drop pin plate and pull the plate forward allowing<br />

you to place this larger bit on the edge of the groove. Slide<br />

the pin away till it nudges the wedge.... and tighten the keys<br />

on the Drop Pin.<br />

Test the other side and check that the blade comes to the edge<br />

of the groove. Do this without moving the sliding bar.<br />

Dry Run<br />

Before cutting the test stick, check that as you run the Pin<br />

down the Wedge either side, the bit will run across the groove<br />

from top right and down at a slope of 1 in 7 to make a pin<br />

with the base the same size as the groove which is the same<br />

size as the dovetail bit. Check that it runs over the stick the<br />

other side also.<br />

Making the Pins in the Test Stick<br />

Now cut the test stick proper.<br />

Zero the cutter onto the scrap and gauge the bit depth using<br />

the piece with the dovetails cut in it.<br />

Drop the bit, Track to the left hand edge of the Stick. Switch<br />

on and make a right-hand cut, from the right side, just kissing<br />

the corner of the groove sloping down towards the left, <strong>The</strong><br />

first pin will allow a right hand cut only.<br />

Track to position number 2, and make a right-hand cut and<br />

then a left-hand cut, from top left side down towards the bottom<br />

right. Be sure to clean the space between the pins. Don’t<br />

worry about breakout until later.<br />

<strong>The</strong> test stick should fit the first and second sockets on the<br />

board with the sockets. And the two should line up on the left.<br />

20<br />

<strong>The</strong> dovetail bit cuts two<br />

grooves to trace the bit<br />

diameter on the stick at<br />

first and second socket<br />

positions<br />

<strong>The</strong> bit is at the back<br />

of the Stick just at the<br />

edge of the groove. Slide<br />

the Pin up to the wedge<br />

till it gently nudges it,<br />

and tighten the Locking<br />

Pins on the Drop-pin<br />

Plate
