Kerf Maker, Fast and easy to make

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.

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!

:~) So a cautionary modification.

Unfortunately these type jigs, and I have the BridgeCity KerfMaker,
don't allow for inconsistencies in thickness of the material that will
fit onto the dado. And plywood typically varies in thickness along any
given edge enough to be more than a few thou of an inch.

And really that is not a fault of the jigs so much as the quality of the
material that fits into the dado.

Agreed. I still use mine to this day (it's going on 6-years old).
Glad to see I wasn't forgotten around here :)

Great idea. The star washer would probably work well but after time
might "chew up" the moveable side enough that it might form "pre sets"
that you'd be fighting to get it set dead nuts on.

It wouldn't take much of an inset with the Forstner at all; just a scosch.

Perhaps Brian's a "waste not, want not" kinda guy. ;) Then again
perhaps he did it to quickly orient the screw end down for set up.

In any event, it's a very simple solution and, like most of his videos,
educational and entertaining.

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.

The cut out reduces the amount of contact surface area, which has the poten=

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:

Pictures, pictures, PICTURES! Wee need to see that. ;~)

Actually I think the new Bridge City Kerfmaker will do 100 mm or about
4". But yes I might as well make one to handle stock that I could
actually use.

These kerfmakers will really come in handy for making slots for drawer
bottoms..... To bad I just thought of that after literally making
hundreds of drawers in the last several years. ;~(

Or all of those slots for the box tops and bottoms. Damn!

You are welcome buttttttt......

if you want a simpler one and your set up sample can be easily set on
the saw table top, this one is as easy as it gets. It does involve
repeatedly using your set up sample with each new dado but it does not
get much simpler than a small piece of wood with a screw in the end of it.

Just after 2:00 he uses the words "a section nibbled away to create a=20
reference spot on one section of the jig".

Sounds to me like it's exactly that "indexing" hint that you mentioned.

OK, Yet another and has to be the absolute simplest to make.

It's simply a "stick" and "a screw".

Brought to you by Brian who used to post here.

I will say that it may not work as well for large stock but maybe it will!

Yes that and or in my case, to remind me which surface indexes the work.
I could easily get that think clocked 90 degrees by accident. I knew
he probably had a good reason.

Yes, I thought that too but it is nice to have something a bit larger to
grab. ;~) and for me if not obvious how to place it I might put it on
the wrong edge when flipping. Maybe that is what the cut out is for, to
remind you which surface is which.

I agree, that is perfect!
Plus, I like the blade width adjustment screw which gives you fine
tuning for different materials.
I have found that some materials glue up better with a tight fit and
some better with a looser fit. Probably due to expansion.

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.

For that matter, the entire wood block serves no purpose. The business
part is the screw which is simply duplicating the width of the kerf. I
know for a fact that most of my full kerf blades are dead-nuts-on 1/8",
so you could probably just use one of those brass set-up blocks or cut a
scrap to 1/8".

That is, if you always want the same "tight" fit.
Having the block give you adjustability for fit tightness and other
blades.

Yes. Most of it has a flat on it so the bolt from the side can hold it in
place well.

Nice. I'll think about it. It reads like they've been available but
they batch orders to save costs. You get it when they get enough to
run a batch. Sorta like a perpetual Woodpeckers' "One Time Tool".

The new Bridge City Kerfmaker is magnetic, so it'll stick to your

I clicked and wandered a little. Apparently there is a larger version

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.

It is gorgeous.

It is so unique that it beats a lot of those one-off tool companies
products. I can see that as being highly marketable.

Might even consider one of the "star" lock washers under the small flat
washer. Or slightly bending the washer so the the center is higher than

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.

Yeah I caught that, I thought it odd that he said that he created a
reference spot as the spot was already there. I guess I should be
