I need to make five dados of 1 1/8 inch each. My adjustable dado blade
only goes to 13/16, so I have to make two passes. Through trial and
error (second try, actually) I created a perfectly snug fit. I want to
use that as a template for the five cuts.
Now, how do I duplicate it?
I'm using a radial saw and cheap pine 1x4s. Waste isn't really an
issue. I guess I could trial-and error all five and toss those that
aren't snug, but I'd rather find some more spohisticated technique.
For instance, I'm considering this:
1. Place the template against the fence.
2. Place the 1x4 against the template, lining up to where I want the
3. Using mending plate and small screws, fasten the two pieces
together. This is not fine furniture, so the screw holes don't matter.
4. Align the dado blade with one side of the template dado, pass
throught the template and cut the 1x4. Take care to not shave anything
off the template.
5. Slide the template so the other side is against the blade and
6. I should have a new dado exactly the size of the template. Repeat
for all five cuts.
Any flaws in this? Any better ideas?
