Router template square
Festool MFS type.

Yet another jig… a template for routing square holes or rabbets, with any router.

Inspired by the Festool MFS, I wanted a simple template, to use with my routers, so I could make a easy fast setup and didn’t have to make a new template for each project.
Why not just buy the Festool template?
Well a price tag of 3725dkk / 580usd / 500euro…
Do I need to say more?

There are hundreds of these DIY versions out there on the web, there are three types, those who use a T-track on the side of a board, those who have a routed T-track in to the board and finally the more prof aluminium profile versions. I went for the last because I wanted this to be another recycle project and just found some laminated solid wood core board cut offs in the street, where my workshop is, also I’m a hobbyist, so it will not be heavily abused and yes, I have to pay the cost, out of my own pocket.

Due to the recycle elements and the fact that I had the router bit to route the slot, the price of my template, was 20dkk / 3usd / 3,7euro, for the eight hex head bolts and washers, in other words 1/186 of the price.

Starting at the table saw, the recycled laminated wood were cut up into strips.

Laminate fiber board and solid wood core.
I think it was shelf material, to make some stronger shelf’s for some bookcases, judging from the rest of the trash I saw there.

To make the T-slots, this router bit will be used, actually bought it to make keyhole hanging, for another project years back, now it finally get to use again.

Marking app depth.

Setting the table saw.

Test cuts.

Running the strips through the table saw.

I do this to take some stress of the wood and the router bit.

Test, test, test.

To make sure I find the right spot for the T-slot.
As you can see, I put a fence on each side of the router bit, to make sure it did not move.

T-tracks routed.

Are they spot on?

Nope, but fine enough, as long as you keep the same side down or up.

Marking up for the hardware holes.

Do you get the picture?

At the drill press.

Let’s drill.

Circe centre hole.

Dust exit hole.

Now the big hole can be drilled.
The drilling with these cup drill bits are much easier, when you have a dust exit hole.

Hole in one!
it’s just dust, there are no tear out, as I turn half ways and drill from other side.

Sides are squared up with a fine tooth jigsaw blade.

I had some flat bar metal in a junk box and decided to go all in on the hardware part.
Here rounding ends.

That’s it.

Nice! :-D

Don’t get to close to disc sanders, here I were lucky it was just the nail.
Yes I know I have the worn hands of a working man.


Making a test threading.

That’s fine.
I pre drilled a 4,5mm hole, the threaded a 5mm thread.

Using a drill for the rest, to speed up a wee bit.

We got hardware.
If you are to lazy for this, or don’t have the tools, you can just use T-square bolts, it will be fine, this is just a little stronger and put the stress load over a bigger area. If you make them with T-tracks or alu, this would be waste of time.

Marking for bolt holes.

Drilling the bolt holes.

Here we are, the hard part is over.
You might notice I also rounded the edges with a 45degree router bit.

My bolts were a tiny bit too long, so I decided to adjust them, instead of just putting more washers.

That’s it.

Test fitting and it seems to be perfect now.
Here you can get the picture of how it works.

To make all bolts same length, I cut a piece of plywood to the correct depth and drilled a hole in it.

So the too much part was sticking out.

Then it was done in no time and they were all the same.

Cleaning up with sandpaper.

Waxing the tracks.

And taddddaaaaaa we got a template.
Mine is a 900mm version, so I can cut rabbets in cabinets if needed.

Loosen bolts and slide to desired size.

Then tighten, it’s that easy to use.

Checking for square and it’s all fine.
(Also on diagonal).

Now you can route with a bush bearing bit or a copy ring on your router

Job done.

Hope it can be to some inspiration, or some templates.

That’s a nice jig / template, Mads! If I ever get a router, I’ll try to keep it in mind.
