Some
people just weren't made for "on-camera." That is a framed grab from the DVD I
did for CMT last year.
I am using this time and space to present to you an "SOP" on how to
set up two "work-in-turn" router bits. That is my term for a bit where you run
one piece through the bit the right way, and then the mating piece, upside down.
Two bits I am referring to specifically: the reverse glue joint bit and the
locking miter bit.
|

|
If you
have either of these bits and have become frustrated in trying to use them, maybe these
SOPs will help. I know that I follow them religiously even though I have used both bits
for a long time.
Since the setup is so similar, I will show the reverse glue joint and once
that is "under our belts" I will then show the additional step to use the
locking miter bit.
|
First
thing is that boards to be joined must be the exact same thickness.
|
|
|
I then
take to sample blocks and mark one "A" and the other one "B."
|
I
install the bit and set the router speed to 14,000 or so.
|
|
|
I have
made a mark on the sample stock representing a point at the middle of the piece of wood. I
then adjust the height of the bit so that the center of the bit is at this mid-point.
|
I then
set the fence depth so that the low part of the but is aligned with the in and out feed
sides of the fence.
|
|
|
I then
carefully make the cut. I amusing the Grripper to hold the piece tight to the table and a
Stots push shoe to actually push the piece through the cutter. This is necessary for the
small sample blocks. When the actual boards will be run, handling them safely will be much
easier.
|
I have
mated the two sample pieces and have squeezed playing cards into the side that is the
lower.
|
|
|
Once I
figure out how many cards it takes to equalize the two blocks, I sort them into two piles.
By dividing the number in half, I can know how many cards it will take me to adjust the
bit height for a perfect fit.
|
Now I set
the router bit height gauge with those cards (1/2 the error) and adjust the bit height
accordingly.
[Turn the page for the exciting conclusion — and how to set the
locking miter bit.]
