how to make circles on a bandsaw

This band saw circular cutting fixture is perfect for making perfect circles every time.
It features a cool adjustable sliding t-
The track makes it easy for you to change the size of your circle, it also has a nice clip and a built-in tape measure to easily set the size you want.
The fixture is sturdy and durable, and you can make all kinds of different circles safely and easily with different types of wood.
Let\'s take a look at the steps on how to build it!
You need the following materials for this building: Wood: 1/2 \"(12 mm)
Baltic birch ply wood hardware: You also need some glue, contact cement, wipeon-
Polished Poly wax.
Let\'s be at t-
Track into the band saw, cut E.
I am setting up the router with a 1/4 straight cut bit and I am wiring up 1/4 with 1/8 length on each side to create t
You want this in t-
The track on the band saw, so it\'s better to make it too tight and then do some sanding to make it fit perfectly.
Next, I need to do a very shallow dado on the motherboard, the width at the top of the t, cutting a where it slides and connects to the track.
Mark on the main board where the track needs to go, it will depend on what band saw you have.
Make a series of very shallow cuts on the table saw, about 1/16.
Then turn it over and clean it up with a chisel.
Next, I will be t-at the bottom-track.
I screw it on the motherboard, install it on the shallow track and test to make sure it fits.
My car was riding high and once I rode it on the track on the band saw, so I took the track off the main board and cleaned the dado a little with a chisel.
You want to find a really suitable place here, so it\'s a good idea to take a moment to make sure it rides perfectly.
Once I\'m well I stick to the track and screw it down again.
You want to make sure the screws sink well so they don\'t scratch the track.
Of course, it is also a good idea to tighten with your hands.
Then check again by placing it on the track on the band saw to make sure it fits well.
Next we have the knob so stick the two small pieces together and cut the G together.
Then create a knob and I use the corner split.
I drew the bolt head on the knob, chiseled out enough space to hold it, and then cut the shape on the band saw.
Next, I fixed the bolt head and let it fit.
Now I am marking the position of the blade on the board.
This is where the sliding track will go and I have also marked the sides of the center section on the motherboard. To make a t-
Fit here, I use the router again and cut about 1/4 on both sides of the cut B & C and on both sides of the center track
You may need to check if these parts are well combined, and maybe you\'ll need to do another shallow pass to get everything together well.
Try it, the track slider is in the middle, by t-
Track on both sides.
OK, Mark about 1 and a half inches on the track slider in the center.
Drill a hole of 1/4 and then in t-nut.
Then align the center slider, cut D, clamp it, and install the Side block.
First pre-drill several holes on two side blocks, put back in place, and tighten.
Then take the screw out, put some glue, and screw the board down.
It is important to screw in first, so you have to build holes first before bonding, because this makes it easier to arrange everything, otherwise the glue will make everything move now, the screws can find the existing holes more easily.
Next, remove the center slide and you want to make sure there is no glue on it.
I made a mark in the middle, 1/2, and then I drilled a shallow hole of 1/4.
Also, mark a line in the hole with a pencil, because if you have this mark, it will make it easier for you to arrange things later.
Then, apply glue to the pin.
OK, now let\'s Connect the block and cut F on the side.
Be sure to sink your head. I use a 1/4 screw here.
Next I will polish any burrs to make everything nice and smooth.
Now, it\'s better to create an indention in order to connect the tape measure so it can be put flat.
So mark the width of the tape and I put it on the edge next to the sliding track.
Mark it out with a knife, use a frame square, and make sure to create a good groove with a knife.
Next I will use the shoulder plane, but you can also do a very shallow cut on the table saw or use a chisel.
Once the groove was deep enough to make the tape measure flat, I applied the contact cement on both surfaces, waited about 40 minutes and connected.
To give some protection to the fixture, I\'m using wipe-
On poly I will add more coats as I will put the fixture on the outside.
I also put some wax oil on the rails on the fixture as well as on the saw.
On the saw, I am here to protect the metal with mineral wax polishing.
Wax will help the track slide better.
OK, now let\'s give it a try, slide the fixture in place and screw the knob in from below.
So let\'s cut a circle.
So first, we need to drill a 1/4 shallow hole in the center of anything we want to cut.
Then find the pins and match them, then we start cutting.
So push the fixture all the way through until it stops and then start spinning the board.
We can change the size we want to make a circle by releasing the clip and moving the board to any size you want.
For example, if you move the slider to 3 inch, the diameter of the circle is 6 inch.
Because there\'s a t in the center slide track-
Connection, it is very stable, not easy to pop up, only sliding horizontally, not moving vertically.
So you can move it very far, fix it down and make a pretty big circle without any difficulty.
Using the fixture, I can create a circle with a diameter of up to 28 inch, but in theory, just increase the size of the whole unit and you can modify it to cut the circle of any size.
