About 8~9 years ago Bridge City Tools came out with a fine
little jig that enabled you to cut perfect fitting dados with
just about any width blade or router bit. That is as long as
the blade or bit cuts narrower than the width of the dado.

They still make them.

I clicked and wandered a little. Apparently there is a larger version
with a magnetic reference stop that will be produced too.

I bought that expensive little jig and have had great success
when using it.

Seems there is a shop made version now and probably the
absolute simplest that I have seen.

Take a look!

Neat. A lot cheaper, too.


Big time. I was inquiring many years ago about the capacity prior
to ordering the original kerfmaker, It had limitations in width.
Looks like I can build a bigger one for 2 X stock.

Why stop there? I made one some years ago that will do at least 4",
maybe more, don't recall at the moment. Why so wide? Because I
often do half laps in fairly wide stock and can use my kerf maker for
them.

Mine is much fancier too, mahogany and brass, drop dead gorgeous



I do a lot of half-laps, too. I'll definitely make one of these.
Not sure I trust the guy's washer grip to hold the adjustment.
I just think it would be too easy to slip if bumped. I would probably
make the half being held in place a tiny bit thicker to make sure it
holds. Or even use a wider washer with a thin rubber gasket.



That was my thought too. I have some Grade 8 washers left over from my
Soap Box Derby days. 1/4" hole, 1.25" diameter. Very sturdy. My head
went right to them as soon as I saw the tiny washer he was using.

Keep in mind a larger washer will disperse the pressure over a larger
area and will require you to tighten the thumb screw even tighter.
I think like Mike indicated a ribber washer under the small washer might
be the trick if it does not hold.

I was thinking that I would use a wing nut that is proportional to the
washer to help apply the pressure more evenly.

I have a few of these too:

You win!
That is freakin awesome.
