Circular saw jig
90° and 45° cuts.

Hi fellow LJ’s, a busy bee flying by here. ;-)

To take away the magic, this is what we talk about, a simple but cool jig for my new circular saw.
In this photo it’s being used for the purpose it was made for – fast and easy 90° cuts of Click floors.
Yes, I’m aware that laminate Click floors are not a lumber guys favorite, but I’m also aware that it is dead cheap and that’s why I use it here.
(I found several versions on Youtube and basically made the max2cutversion – thank you. Links at end of blog).

Let’s start by showing where the floor was put.
This is my new allotment house, Postgaarden (Postalhouse), named so because the main house is an old Railway post van, that were put on the allotment and converted into a small house back in the fifties.
It will be my summer hide out, a place for peace, quietness, gardening, time in the workshop and once the place is fixed, hopefully also a place to just hang out, with a good book and a pipe of tobacco,
(Yes in Denmark we most often, have houses on our allotments, small simple houses, often with no electricity and sewer, just water supply, so not completely off grid).

Here the garden and backside of the house.
The house part you see, is my workshop there and the greenhouse has been converted into a bath house.
(Quiet a lot has actually happened, since these photos were taken on the day, I bought the house).

Let’s get back to the jig, here we are back in Copenhagen, in my workshop.
A piece of board was cut to size, I used this type, since it can take some outdoor use.

Cut some dense wood into square, just shy of the saws capacity.
Screwed one of them to the edge.

Just like this.

Next a few strips are cut on the table saw.

Glue on one side.

Predrilled holes with countersink and screws ready.

Like so.

This forms the tracks for the circular saw.

Since I want a 45° option, the one side is left open.

Tracks are adjusted to fit the saws base.

The 45° degree hold is adjusted and then screw holes are drilled through.

On the back the hole gets a countersink, so the bolts don’t stick out of the board.

Wingnuts will hold the 45° hold, when in use.

Nice and easy.

Then it can also cut different angles if needed.

Next a handle was made, by drilling two holes with a hole saw and cut between then with a jig saw.
All that’s missing is to screw the last track down, and wax the tracks.

Here we are, a circular saw jig, ready to be brought to the allotment house and used with the cordless saw.

Here we are back at the allotment, in my new workshop, I restored an old workbench and put windows in the shed, amazing what a difference it did.
And I am a happy monkey, with two workshops now. ;-)
As you can see there are a gas light, since there are no electricity, this is why I set up with cordless tools and bought five 5amp batteries for the saw and drill. But I also have a generator, so I can use table saw, drill press, grinder and so on, when needed. ;-)

A look into the house, here the bedroom, gets a new flooring.
IKEA laminate click floor, yes I said it out loud. :-D
An old vinyl was under the carpets, so it was a no sweat deal . foam pads and then the click floor.

Cut to length with the new jig, this made is so fast and easy that it was all done in a few hours.

I set the saw up outside, then dust was not a problem.

The previous owner gave me two of these workmates, guess I one day have to stop hating them and admit they are super handy, for house work. ;-D

Now for the dining room.
What a sexy floor that was hidden under two layers of old carpet!

At the end of the day, the hose looked like this, I also did the kitchen floor.

Some window trimming are cut with the 45° hold.

It works just perfect.

Straight cut.

Here some oak for a window over hang.
(My new generator in the back).

Now it was time to put click floor in the living room, that’s the corner room with all the windows.

Once I got the vinyl of there, reality emerged…
The floor under was full of black mold and partly rotten.
So the circular saw came to use.

Removed the rotten floor and also had to replace parts of the structure in the walls.
It is an old terrace that has been converted into a room and it was non treated wood, put directly on the concrete tiles. Also there had been a leak in the roof for several years, so I guess it was time…

Charging a battery with the generator, this was why I bought three extra batteries, so I now have five.
Also making a fire out of the old floor, it was gone in a few hours.

Building a new floor, but that’s another story and I don’t know if that’s a LJ one…

What happened?
New color?
Naaaaa, just made an extra jig, so I have one at home in the Copenhagen workshop also.

This time metal tracks.
(These are not really perfect as they are not perfectly 90°, but they works).

Also added stops and a safety block, so the sawblade don’t get out of the jig.
(Did that to both jigs).

Back stop.

Simple yes?

With 45° hold.

For 90° cuts.
(The saw kerf on the left was a mistake, I ran the saw wrong way first – laugh).

This one also got a handle.
And here it is, ready for use.

Conclusion: I love the jig, it’s easy to make, easy in use and easy to bring, makes all kind of around the house work done precise and fast.

Max two cut version:
Mistry version:
Adjustable angle:

There are many more, the hen and the egg…

Hope it can be to some inspiration, who knows, perhaps even a jig.

What a wonderful space! I could see myself spending a lot of time there!

Thanks for the links to the jig builds.

I really like the little reminder to watch your fingers when working in the shop!

Hi Mads!
I see you are part of the tiny house movement. And as always, enjoying yourself making something. That is a very cool little workbench- something you already had or a recent acquisition?

As always Mads, brilliance and simplicity! I love the safety stops and kerf block, great extra touches.

That’s a great jig Mads. Simple and precise and portable. Hope you get everything done that you need to get done before the cold weather comes. You’re making huge improvements to the place already.

Nice jig and nice allotment Mads, A great place to spend some pleasant summer and fall and spring days. Personally I prefer the click parquet as it looks great and is easy to install.

Hi dear LJ’s,
Lew, I already love the place, it’s only been mine for few months now, but we have kind of grown together by now, so I was a little touched, when I was down there last week closing it up for the winter, for the next five months, it will be winter closed and I’ll have a hard earned pause. ;-) Lovely to have something to look forward to though. The finger reminder. :-D It gives me a serious smile.
Marcial, Yes I’m tiny house and off grid (almost), so kind of trendy here in my fifties – ha ha ha. ;-D The bench was bought for the house, I got it for almost nothing (50usd), but it was also in a poor condition. It don’t need to be perfect down in the allotment, part of allotment life is simple living and recycle.
PurpLev, thanks, as you can see I ended up making two, that kind of says it all yes. Smiles.
Brit, I made it before closing up, even more than I had planned, since I decided to finish the floor up and a friend came to help with a door (I’ll make a post soon). Have to admit I was really tired and it was so cold the last time I was there, that I was happy to close it up for the winter -4c / 25f out and +7c / 45f inside in the morning when I woke up. Thank you for having your sweet daughter visiting me, here in Copenhagen, it was a real joy. <3>s not… But these floors were so easy, cheap and looks really good, so I have come to like them by now. ;-) The house really became a house after getting rid of the carpets and getting floors.
Thank you guys, I truly enjoy your words and to share this new path in my life with you.
Best of my thoughts,

Mads, I somehow missed this when it was originally posted, but they are pouring the slab for my workshop tomorrow, which has me thinking about a floor for it. I think I will be using laminate flooring as well, as it will be easier on the feet than concrete, and still cheap. So I will probably be building a jig mich like this for cutting it to length. Thank you for the idea!

Thats cool Dave, you will soon have a workshop!
Put some foam under the floor (the best you can get at a fair price), this will make the floor softer for your back also.
The floor I put here are quite thin, I dropped something hard on it and it made a hole, so perhaps a thicker quality for a workshop, or just accept the tear and wear.
I can highly recommend the jig by now, used it a lot and I find it super cool.
