The
drawer stock I made from 3 layers of 1/4" ply has set, and I can now rip them to
dimensions called for in the plan.
|
I can't go by the plan
dimensions for depth because I am going to be doing 1/2 blind dovetails and, more
importantly, I will be using slides that require 1/2" clearance on both sides. If you
have ever installed slides, you know that a drawer that works well has to have exact
clearance. The best way, I know, is to use the 1" width of the adjustable square to
check the clearance. If it is over slightly, I can shim the slide. If it is under, there
is no easy cure.

Having cut all the drawer
stock, I move the Incra TS III to the router position.
Of course, I am going to be making half blind dovetails using the Incra
system. Of all the drawer joints that are available to me, I think the Incra System is
fastest. It can make great dovetails even in plywood.
|
I attached the
Incra routing fence. Even though I made a shop fence with vacuum pickup, I must use this
fence since the vertical fixture rides on it. I simply position it so that it is centered
over the bit.

The Incra Handbook
can be overwhelming with all the templates, but it is really quite simple. I first run
through the templates looking for the dovetail size that will work on my board. Then,
I check to see if I have the dovetail bit that is used for that template. With the
template selected, I can proceed with setting up the system.
|
When I built the router
storage cabinet for the SuperStation, one of the smartest things I did was to customize
the top drawers to hold the 50 templates. I am looking for the DOVN template, and it is
right where it should be. (If only I could say the same for everything in the shop.)
I install the template in the Incra slide carriage.

 |
I use the bent wrench
to install the right dovetail bit. It is great to be able to change bits from on top the
router. (I will admit that I had to take the router up and out to change speeds. The
downdraft chamber precludes making those changes from below.)
|
I have placed a piece of
scrap wood over the bit and am using an Allen wrench to lower the bit height. I want to
"zero" the bit.
|
 |
 |
Having zeroed the bit
height, I can turn the crank clockwise exactly 7 and 1/2 turns. This will accurately set
the bit height to the 3/8" (.375") that is called for in the template details.
There is no more accurate way than this to set bit height.

I lock an insert plate in
place.
