I just finished this project. I built it in to a rolling cart that slides under my workbench. I can remove it and slide another device in its place. I cut two 16” rounds in minutes. My wife is thrilled, but I have a feeling my “me-time” just took a major hit. I think I will be cutting more craft projects than I bargained for! Thank you so much for sharing this.
Great job. Best tutorial I have seen for a jig yet. The roundover and radius work, even though not filmed, made it a great looking jig making it worthy of being made of Baltic birch. I am making this for a community woodshop in various sizes(for ease of use) and will be making several pin combos. I am thinking maybe a little bigger pin and knob combos, certainly smaller, both pointed and squared off . I will make the squared off pins so that do not go all the way through the wood, maybe 1/4", 3/8, + 1/2", so one surface is left untouched/ presentable. This is going to be a teaching project to introduce several tools to newbies. I have several 1" X 2" 3D printed open boxs I made for 1/4 hex bits and will glue a magnet in the bottom so they do not run off. Your use of a magnet was great. Thanks again
Awesome ideas! I love hearing about folks who come up with obvious improvements to my designs. Thank you so much for sharing your plans, and for watching!
In most cases, rather than doing the math, it's easier to mount the router in the jig, then directly measure your radius off the bit itself. Great video, thanks.
@7:25 Two tips borrowed from the metal working trade. Plywood is a laminate of differing sheets applied with grains at opposite angles for increased strength. When "wood butcherin" millimeter accuracy is not normally a prerequisite. Go ahead and drill, but know because of those odd angled sheets in the ply a bit can "walk" on you. To increase accuracy in ply; Tip #1, first pre-punch the mark with a good sized finishing nail, or smackable wood awl going at least through the first layer of the ply, plus. Tip #2, pull the nail/awl and use drill bits of smaller size working up to your finished hole. More work, but in the odd case where wood has to match machine shop tolerance this stacks the odds in your favor. Good video! I'll make one of these.
Nice vid. Small tip... Instead of marking the holes from your router place and drilling, use a self centering drill bit directly from the base plate instead of marking for the holes. Will be perfect every time. Of course, you need to have self centering drill bits :)
Using the jig hanging off edge of table was enlightening. Needing to cut some rings so this should be the ideal method especially since I don't have a fancy plunge router like so many other video show using. Thank you for your video contribution.
Very nice tutorial. FYI if you have an ACE hardware in your town you will be able to find everything. I thing I spent around $8 with enough to make 2 templates.
08:40 *No* excuses. That perspective is just about right. That cute little jig now looks like a monstrous Star Trek spaceship. Captain *Kirk* salutes you.
I have looked at so many videos for circle cutting jigs and yours is by far the best! My only problem is that my Home Depot doesn't have threaded posts or knurled knobs in stock, ever. Asked my husband to drop by the Lowe's near-ish his work (45 minutes away) and he picked up everything I needed. Looking forward to building one tomorrow. I am going to set up to put my small, hand held router on the other end for circles in 1/4 stock. Thanks for sharing!
I am a 25 year veteran teacher. You have missed your calling if you are not at a K-12 or college teaching this stuff. So amazingly comprehensible. Impressive.
@@AmplifyDIY My HD had none of the parts, so I ordered from Amazon - no biggie. The extention that you ground into a point. Given you have ab abundance of free time, could you post an amazon linke to it?
For historical record it's now week six of the Global Coronavirus Lockdown (late April 2020). Deep boredom has gripped the entire world - but a router circle cutting jig is the solution. I'll be having a go at this later today - when I've got out of bed.
Got it done yesterday thanks to your vid. Yes, the parts were difficult to find. Thankfully, Lowe's has a decent specialty hardware section. Now on to the project that inspired this build - building a vortex dust collector stand. Indeed, especially in woodwork, necessity(mine) is the mother of invention (yours). Thank you.
Fantastic! So glad you were able to finish your circle cutter. I built min specifically because I also needed to build a dust collector. I went with a Thien baffle design: ua-cam.com/video/tMeU6_gMNKo/v-deo.html Best of luck with yours!
@@AmplifyDIY I went with the "JohnBuildsIt" plan. Just got it done. Not perfect but decent for my needs. I regret not having more capacity such as your Thien model. Like the idea of moving collector around to each individual machine rather than building an entire plumbing system. Not only does it take up less space but eliminates the problem of suction loss over distance which I presume would be unavoidable. Can you comment on that particular issue? - my vac is a 5hp and I presume it cannot be as strong pulling dust from a machine on the other side of my woodshop as it is for more proximal work.
Awesome video! Nice design! I never thought to turn it upside down and use the jig as a sort of router table. I will make one of these to help me build a thien baffle dust collector from your other video! Thanks!
Nice video. I use 1/4" ply. It has some flexibility so I can tilt the router up off the workpiece a little bit when I start the motor. I don't have a plunge router.
I like this jig more than most that I have seen. It would have been great to see the the pointed piece you made in action. Did you make another video showing that by any chance?. Great video 👍🏾 I also like the fact you left in your mistakes, makes me feel that I am allowed to make mistakes without beating myself up 🤣🤣👍🏾👍🏾
Hey Michael - Thanks for the kind words! I don't have any specific footage of the pointed pivot in action, but it works great. It does leave a small divot in the work piece, but nothing major. Thanks for watching!
For the pivot point I use a small block of wood with a hole in it to hold the pivot, sticking double sided to tape to the underside of the block to keep it in place. This works for me and leaves no mark.
Ok, yup. I've been looking for a circle cutter jig. I've seen some janky ones using a jigsaw, and I've seen unnecessarily confusing ones. This is the one I'll be building (though I think I'll make a small change to how the router mounts!). And because my work table will have T-track (waiting for it to arrive)(SO patient.. lol), that's how it'll be fastened to the table. Cool!
Also, I checked my local Home Depot website for the parts.. I recognized the Chicago screws already so I KNOW they have those, and they had that exact brass knurled knob as well. I love it when projects are easy to source parts for...
Well done! Thank you for this extremely in depth video! I like that you kept it simple and all the parts you used can be easily found at any local hardware store. Most videos require you to order something special from a certain website. This can literally be bought, built, and used in a matter of hours for cheap.
Only thing I would add is a reminder next to the scale, not to forget to allow for the thickness of the bit. I don't know how many times I have made simple mistakes. Hopefully the reminder will address this issue.
Thanks alot, I did watch many tutorials. This was the one that I kept cause it was perfect for me. I tried routing a speaker hole by freehand and painfully learnt that this is the way to do it. I also tried using the whole diameter of the hole I tried to make. Now I know that you should use the radius, wich seems alot easier. :)
I have that exact same router. Oh JOY, a circle jig I know will work well with my router. Everyone else seems to have plunge routers. Which is why I've never built a circle jig, even though I so desperately need one.
Told my wife I was going to make a new table for the breakfast room. She said she wanted the table round this time. Since my table will be 48 inches in diameter and the CNC router will only handle 30 inches I will make a 24-inch jig instead. Will make the plastic handle with my 3D printer. Thank you for the idea! :-)
Great video! Detailed explanation/instructions as well! Thank you for posting! I only need to make a circle or two for some panel designs for my deck, so I could probably get by with making something easier. But the design of the jig seems to allow for so many uses, I may have to just go ahead and *try* to make this one for future uses. Decisions, decisions.. Thanks again!
Your third center post should be a larger pad (6"?) that you can carpet tape to your material and not leave a gouge or center hole. I like to use 1/4" masonite for these builds; you don't need longer screws for your router mount.
Magnet is genius. I might would add a conversion table for the cut radius and router but width. That way you don’t have to think about it. Also in that same table could be whether you are cutting inside or outside of the circle.
New subscriber here. Thanks for this very well thought out tutorial. You are correct about other tutorials, they always seem so complicated, and make the process seem so esoteric. Not this one, your tutorial is very well laid out, and very easy to follow. Thank you, can't wait to make one for my little Bosch router. Who knows I may have to get a bigger one like yours.
Best thing I've seen on UA-cam, mate! I was struggling to make proper circles and was thinking of making a router jig but you have made the most elegant, easy to source design.
Hi Michael! At the 16:17 mark of the video you can see I just screw a couple of wood screws with washers through the adjustment slot of the jig right into the top of my workbench to fix it in place - The video is sped up at that point and it goes really fast, but that's what I did. Hopefully you can see it if you click the timestamp above. Thanks for the feedback and for watching!

wow! you just saved my day. im making speaker box and i wanted the hole to look good. thanks.
Simple but useful. Thanks for sharing and congrats from Brazil.
“Great job” now I need to do is go out to the shop and make one. ⭐️⭐️⭐️⭐️⭐️

Nice idea on blind pins for cutting from back side of materials.
This thing is so satisfying to use, I've cut up a lot of my scrap plywood just playing with it. :)
In most cases, rather than doing the math, it's easier to mount the router in the jig, then directly measure your radius off the bit itself. Great video, thanks.
I like your work and the way you explaing the operation.
Great simple tutorial. For circles I don't want a hole in, I use double sided tape on a T-bolt and that becomes my pivot pin.
What a great idea! I’ll have to try that. Thanks!
Thank You for the very fast reply and great information.

Thanks Lance! I'm glad it was helpful!
Thank you.
You're welcome!
Great video. Showing the router beneath the work to cut out the circle was very helpful.
Very nice tutorial. FYI if you have an ACE hardware in your town you will be able to find everything. I thing I spent around $8 with enough to make 2 templates.
I didn't even think to check at Ace. Thanks for the tip!
This is the coolest router circle cutting jig I have seen so far. I will have to make one.
Thanks for sharing
When you place the router base plate on the plywood, use a Vix bit to locate the holes . Much more precise. Great setup with the knob.
Now I know what those Bosch Clic-Change 1/4 in. Self-Centering Drill Bits are called. Another good idea.
Yes very good... crowd very very quiet at the end.. stunned i guess ;-)
Thanks a lot Mate. Great video.
Thank you!

Thank you, you just saved me some money. I have all the parts already in my parts drawer!
Nice!
Thanks for this. I built one out of laminate flooring, and it works beautifully!
Nice! I never would have thought to use a piece of laminate, but that would work great!
I need this in my life. I have been looking at where to buy wood rounds and they are so expensive. I need to make this and cut my own with my router.
Thanks Great Video .

Best one by far!! Simple, thank you
I loved is beatiful thankyou.
Awesome. Great rig!
Thanks! 👍
spot the three screw holes with the router base itself, and use the plunge function of the router to spot the center of the hole.
Good tip!
Thanks, great tutorial, worked perfectly for me.
This will work great for model railroading return loops
Your third center post should be a larger pad (6"?) that you can carpet tape to your material and not leave a gouge or center hole. I like to use 1/4" masonite for these builds; you don't need longer screws for your router mount.
