Circle cutting router jig» Famous Artisan. Here’s a simple alternative to some of your standard shop made circle cutting jigs. This circle cutting router jig is infinitely adjustable so you can make it to cut any size circle you choose. Start with a piece of 1/2″ plywood about 2″ wider than your router base, and as long as you. Remember, the [ ]. Making a Circle Cutting Jig using the router.  The type I have lets me leave the baseplate for the template set on the router at all time, and I thought a good way to mount the router on the circle jig was to use the correct bushing, and it would fit in a hole in the jig. Quick, easy and accurate. For most circle cutting, the bit used would be 1/2″ diameter or less, so I chose a guide bushing that has an outside diameter of 5/8″. I drilled a 5/8″ hole in the plywood of the jig for it to fit in: The main part of the jig is made from 1/4″ plywood. After drilling the hole, I cut a 3/8″ slot down the middle and trimmed the base to size: The ro. DIY router circle cutting jig made from 7/16″ thick PVC board. The jig is 20″ long and /4″ wide. It has a 14″ long slot in the middle of the board with about /2″ of space on one end to mount my Dewalt DW router. It will cut circles ranging from 6″ to 32″ in diameter. The slot accommodates a sliding pivot pin that is used to set the circle diameter. Before cutting the slot, I first routed a 1/2″ wide recessed groove on the underside of the jig that is approximately half the depth of the jig material. The pivot pin slider plate travels in this groove. The groove for the sliding pivot pi. We could buy longer mounting screws, but unless you diy router circle jig index a set of really long router bits, the thickness indxe the base may limit the depth of cuts you can make with the finished jig. Step 1 Preparing the rotation point disks. The circle with the slot should now be at the top and the opening of the slot determines where to drill the hole in this piece. Inxex build instructions are much more complete than any of the other sites. Feel free to let me know in a comment below.

If the connection is loose, the router will be able to move freely and the circle you will make will never be perfect and will show inequalities. I made the slot in the wood with my crosscut sled and the table saw. The height of the saw blade should be set equal to the height of the little bar on the back of the router.

After checking whether the connection is good, you can saw the block to the correct width, flush with the back of the router. In order to clamp the block between the router base and the button, a slot must be made so that the piece can slide over the bolt. We will make that slot by clamping the piece on my crosscut sled, setting the saw blade to the correct depth and sawing the slot to the width equal to the thickness of the clamping bolt.

To attach this piece to the threaded rod we will drill an 8mm hole. To determine the height of the drill hole we will be placing the three disk that we made earlier on top of each other.

The circle with the slot should now be at the top and the opening of the slot determines where to drill the hole in this piece. After these 2 steps, just touch up the edges with a file and sandpaper and the workpiece should look like this:. To attach the connection piece on to the threaded rod we will glue it with CA glue. Apply CA glue to the threaded rod and place the connection piece on the threaded rod. The slot should be on the outside and the end of the threaded rod should not go beyond the inside of the slot.

After the connection piece is in the right position, the accelerator that instantly hardens the glue can be sprayed on. Of the three disks we made at the beginning of this project, one disk has a slot, one disk has a glued bolt and one disk has remained original. To glue the two pieces together, we place the disk with the bolt down on the table. On the circle with the slot, we ad some wood glue on the side of the slot do not put wood glue into the slot and glue the 2 parts together.

Wood glue does not become firm until it can dry under pressure. Therefore you can clamp these 2 parts or use brad nails as I did. If you do not have a nail gun, you can alternatively use small nails. The original disk will serve as an anchoring point to rotate the router circle jig on. For the moment we are not using this one. Now that all the pieces are ready, they can be brought together.

On the threaded rod, we first place a nut followed by a washer. Then we slide the threaded rod through the opening of the center rotation point. To fix the threaded rod on the center point, we place a washer on the outside again, followed by a nut. This Router circle jig is very easy to operate.

Start by connecting the jig to the router. Slide the connection piece behind the clamping bolt and tighten it. Take your workpiece and determine the middle on your workpiece.

Mark this center point with a pencil so that it is clearly visible. Apply double-sided tape to the bottom of the third disc. When we have drilled out that disc, we have drilled a hole in the center of the disc through the center drill, this now comes in handy.

Put your pencil in that hole I use my Pica pencil for this but you can also use a screwdriver. Place the point of the pencil on the previously marked center and now lower the disk. This way you have placed the disk perfectly in the middle of your workpiece.

Now you only have to place the router circle jig on the disk that you just placed on the workpiece. Do this by entering the bolt into the hole of the disk you just placed on your workpiece. Make sure you tighten the nuts properly! Due to the vibrations of the router, these can come off and the diameter of the circle will change. Building a workshop can be tough and involves a lot of trial and error. I know because I was there too. Thanks to this training, I gained better insights into building a workshop so that I could spend my budget more efficiently.

Dag Christofix, ik heb een vraag. Volgens mij gebruik je lijm met een versneller of accelerator. Welke lijm is dat en waar kan ik het kopen? Het ziet er namelijk erg eenvoudig uit. Alvast dank voor je antwoord, groeten, Evert. Hoi Evert, Dat is lijm van starbond. Bovenaan deze blog kan je een link vinden in de materialen lijst.

Ik heb deze lijm toegestuurd gekregen door starbond om te testen en ik ben er super enthousiast over. De lijm is snel en sterk. Absoluut de moeite! Hopelijk heb ik je kunnen helpen. Indien je nog vragen hebt mag je me steeds een emailtje sturen. Christo, I just found your website. The build instructions are much more complete than any of the other sites. I do have one small problem: here in America; we use imperial units. I need to convert all of your measurements.

Thank you for the kind words Bill. I have never worked with imperial units so this is kind of hard for me. I will find a way, and when I do I will offer plans in imperial units.

If you are cutting all the way through your material, make sure to hang the portion being cut off the table, and keep rotating the material periodically during the cut to keep from cutting the table. You could also put a sacrificial piece of scrap underneath the material instead. It's generally safer and easier to cut outer edges of circles in a counter-clockwise direction, and inside edges clockwise. If you don't want a small hole in the cener of whatever you're cutting, you can use a sacrificial piece on top.

Drill a hole in a piece of scrap, and use doublesided tape to secure it to the workpiece with the hole at the center of where you want to cut the circle. Then just increase the depth of cut by the thickness of the sacrificial piece, and cut as usual. Alternatively, if a hole would be acceptable on the underside, but not on top, you can drill the hole only part way through the material, and cut from the bottom.

Have fun, and be safe! I have the same fixed-base Porter Cable router and made a circle-routing jig for it. What I'm trying to sort out is how to start the cuttingdo you have to loosen the router height adjustment while it's running and rotate it down to the depth you want and re-tighten?

I probably should just use my plunge router, I guess! Reply 7 months ago. Reply 2 years ago. Don't ever loosen or attempt to adjust the depth while it's plugged in, let alone running. A plunge router is safer, but it can be done easily without one. Set the depth with the router un-plugged, plug it in, turn it on while holding it securely it will jump a bit when you turn it on , then slowly lower the bit into the workpiece while keeping the side of the baseplate against the fence.

Tip 2 years ago. One very important thing to remember is to take into account the thickness of the cutter bit you are using, and compensate for half of that in your finished circle diameter. This is great! I came up with a really similar jig on my own.

Good to see it's a common solution :. Once you tighten the nut to hold the desired size of the circle, it seems like you will be tightening the fixture to the work piece making it hard to go around.? Reply 5 years ago. What none of the pictures show is the post that sticks down from the jig under the t-handle.

When you tighten the t-handle you are only tightening the post into position. The post then will drop into the hole you drill in the center of your workpiece and allow the jig to freely rotate deg around it. Nice looking jig. Having a good jig is the secret to most of my successful projects. I use this circle cutting technique frequently, but I just take a long strip of fiberboard and set it up for a fixed radius.

I just posted my Cardboard Ball Chair www. If I cut a lot of circles of various sizes I'd certainly make a jig like this. The all-thread allowed for very precise adjustments and long radii. I used this to make concentric rounded grooves in an old wood door. The resulting pattern made the door from a very junky piece to something that looked like art.

I love using radius techniques whenever possible. You can do a lot with them. By tashiandmo Follow. More by the author:.

I would think that most of not all of Best Router Circle Jig Index these materials could be found in most workshops. The cost to purchase these items would only be a few dollars. It does of course assume that you have a router to use the jig with. Make a mark on the center line one inch away from the outer edge of the baseplate. My baseplate was round, but many will have a flat edge.
