Precision Circle Jig

Two versatile, adjustable router circle jigs that offer excellent precision, and do not require unscrewing the base plate. A rugged, low-cost design that is compact, easy to store, and sets up in seconds.
I am not offering plans, because this jig has to be adapted to each router model. However, the video contains all the critical dimensions and enough construction detail to guide a viewer who wants to build a similar jig.
I am not sponsored by DeWalt, Coca Cola, or any other products seen in my videos.
Sources for components:
The plunge router I used: amzn.to/2F47kGG
Ordinary steel rods are widely available in most hardware stores, and from many online sources. The zinc-plated variety resists rust better than the plain steel. Precision milled rods, such as those for CNC machines, are not required.
The threaded inserts I used are a zinc alloy made by E-Z Lok and available online. A package of 100 costs about $15. Many other suppliers offer similar products, and they are available in both metric and imperial sizes. Many hardware stores carry them.
Skate bearings measuring 22mm wide with an 8mm hub are available in many stores that supply skateboards and roller skates, as well as from more than 20 different suppliers online. They are typically about $1 per bearing. Cheap ones will work as well as premium versions for this use. However, the exact inner diameter of the hubs vary from brand to brand, so measure them with a caliper to match them to the threaded rod you are using.

Everyone before me has taking the words out of my mouth. I NEVER COMMENT on any KZbin videos because there is no time for arguments or for me to clarify to someone who took my comment the wrong way. BUT, you sir are an PROFESSIONAL PROJECT ENGINEER / MACHINIST and I am very impressed and will now delete all other subscriptions I had for this type of work. As there is no need to waste time with anyone but the best!. And that is you sir with all due respect and admiration. Thank you for sharing your experience and knowledge! Your # 1 FAN Hugo Prado.

After watching both of your jig videos I'm left wanting for a tour of your shop like a kid standing outside the Wonka factory.

[@maxwellbarnhart3294]

How I cut metal rod tends to help A LOT with locating the center of the rods (to gauge how far apart the holes need to be.) 1.) use a pipe cutter (the kind that you clamp and turn around the pipe like a can opener) and get as deep a score line as I can. 2.) put the end of the rod in an electric hand drill. If its long then you may need to prop up the other end. 3.) use the drill to spin the rod while sawing it at the score line. Since your setup is like a makeshift lathe, your cut is always going to end in the center of the rod. A tiny nib will be left in the dead center if done right.

[@hambone4402]

This video is one of the most professionally produced I’ve seen on KZbin. Thank you.

[@scottlake8806]

The best router circle jigs on KZbin. I also like the tip of inserting the thread into the timber using the drill press. Thanks

[@sonofsandwiches6892]

perfect timing, I just bought this plunge router kit from Dewalt. Gonna make this jig!

[@AzogDefilerFromMordor]

Its rare to see a tutorial video without powertool noises. Good job man.

[@antoniomoscato2152]

Thanks Patrick, I really apprecciate your clearly way to explain you projects

[@sibat777]

Just love the improvised internal flap slander - genius - definitely adding that to my bag of tricks👍. Loved the circle jig too 😃👍

[@SteveZodiac777]

Thanks for 2 excellent videos of your ingenious and practical jigs!

[@HaynesJP]

Made the first one last night to use for cutting perfect speaker holes! Thanks for the great idea!

[@johnnymatallana]

One word: GENIUS!!

[@_J.F_]

A pair of very well designed circle cutting jigs! The presentation, and explanation, is superb leaving me in absolute no doubt about how to produce either jig. The graphic animation also worked wonders and all together one of the best jig making videos I have ever seen. Thanks a lot for the effort. P.S. I love the metric measurements as well!

[@robertsullivan2396]

Great video Patrick. Thankyou

[@PeanutsDadForever]

Well done. A simple and effective jig. Thank you

[@rsitch1]

Outstanding Patrick, thank you! Bob

[@henrysiegertsz8204]

Great videos Patrick, beautifully, designed, executed and finished.

[@Hp2G1]

Brilliant, and simple enough! Clear and precise instructions. Thanks for the video. :-)

[@WillN2Go1]

I really like how you handle metric and imperial measurements. It's seamless and practical.

[@plumbgraham]

Mr. Sullivan you are a pro!

[@JiancarloUlloa]

Thank you for making such a great videos and share your knowledge!!

[@coachluccity1754]

You're so very appreciated. Your videos are easy to watch. You keep it simple and that's a biiiiiig plus...

[@joeennis2571]

every day is a school day many thanks , greetings from Ireland

[@martinedelius]

Very nice! I'll definitely use a lot of ideas from these builds when I build my own jig(s).

[@stewartmcmanus3991]

Yep, that was great, thanks Patrick.

[@harrywoodman2988]

From an American scientist living in Europe, I appreciate that you give your measurements in both Metric and Imperial! So do my friends in the UK, they have to deal with both all the time and stopping to do the calc is just another hassle.

[@JosephLorentzen]

I really appreciated the simple use of the drill press to insure the inserts went in straight. Thanks.

[@arthurcrosby5755]

Thank you Patrick. Your designs look really good and your excellent video presentation is easy to follow. Well done. 👍

[@agustinruiz7129]

The best one I've seen so far!!

[@lewisway6811]

Well done Patrick.

[@hernanrpaul]

wow! absolutely helpful! thanks for sharing Patrick!

[@Blueboy9055]

Excellent in-depth instructions. Thank you 👍👍

[@markjarman7819]

Absolutely fantastic jigs.

[@BrightSparkIdeas]

Brilliant video, clear easy to follow directions and advice, thank you for sharing.

[@suzannecadgene1781]

Wow! I made something similar using wood BBQ skewers (I'm a cook by trade) glued into a crossbar instead of your through metal rods. I adjusted the circumference at the router, not the pivot side. This is much more accurate and easy to adjust. Thanks!

[@montewoods4766]

Very crafty stuff Patrick!

[@talegunner115]

I love your videos. Fantastic job and very professional. Your directions are direct and clear.

[@sjoerdc7209]

My compliments for you're idea's and video editing

[@RomanWeisman]

Thanks Patrick for sharing - After struggling with and finally returning the Milescraft circle guide kit I found your video. As you mentioned, the second option swivels and held in place by glue rather than a screw that damages the wood, which is phenomenal.

[@robertbrunston5406]

Awesome jig! Thanks.

[@alexanderlavrov3970]

I never seen any video so good in explanation , so clear and so good. thank you so much Sir Sullivan , subscribed .

[@richarddefour5220]

Thank you! Very well explained and useful! Nice work

[@benjaminl3084]

Very clever Patrick! I had already made a version of the first one but now need to make the second one. Subscribed!

[@smoleyhokes]

This is something that I will have to build. I've seen others but this is the best.!

[@Omarateastwind]

I just finished building the simple version, and it's great! Cost about $5 and a little bit of time...thanks for sharing and for making a fine video.

[@mauriziofaedda7061]

Very good quality video with excellent explanation and clear indication of the drawings.

[@zahidjaved4897]

Thanks sir for sharing your nice, clean and accurate work.

[@pacowang283]

Nicely done sir!

[@carlopizzi868]

Complimenti per il progetto e per il video molto esaustivo.

[@huwdavies5264]

A fantastic pair of jigs. Cheers, Huw

[@ElRel]

Really nice approach here. You are bringing engineering disciplines into woodwork. Also, thanks for the metric :-)

[@petermcmurray2807]

Thanks for the tips re inserts very valuable

[@christinecahill2874]

Stumbled across your channel a few days ago. Definitely sub'd Your attention to detail & your engineering is very helpful to the mid to upper level craftsman. Thank you for posting 😊

[@Raptor-700R]

Wow never saw it done that way. Love it i will defintely make one for myself great vid

[@bati800]

great method. thanks for sharing

[@harrypalmer3481]

Brilliant! Thank you.

[@thedistractedmaker]

Fantastic content! Thank you sir

[@farhadtowfighian5743]

Thank you for a detailed and useful jig. I like and appreciate your way to show and explain how to do it, specially when you show it both in inch and mm which is easier for us living in Europe.

[@colinbateman8233]

I like your trick using your drill press

[@benjamindebellis6664]

SUBSCRIBED I like how you have both a working drawing and then show how you do it. Awesome job sir!

[@cmal90]

I’ve just found your channel and had to put a comment down. I’ve looked back at some of your previous videos and am amazed at your ideas and projects. All so well filmed and edited together, will be checking out all your other vids. Hats off to you and thanks for sharing your ideas. I already have a few videos saved for later that I will attempt. Thanks

[@SGuilarducci]

Excelente JIG. Parabéns 👍🏻👏🏻👏🏻👏🏻

[@skippylippy547]

This is awesome! Thank you! :)

[@edgewrld]

amazing precision

[@clyd3fr0g]

Great tips for installing threaded inserts! They can also be installed with an Allen key (hex wrench) but keeping the insert vertical is challenging.

[@pasqualeparente9776]

I love your jig, but I must admit that the more you tube I watch the nicer the jigs I see...

[@juanbenito1383]

Excelente amigo! Un diseño extraordinario, Gran herramienta la que ha ha creado.

[@NikitaMaree]

Thank you great Video.

[@glenngulley1375]

Great video and idea, thanks for sharing this

[@albatros1752]

Briliant instructions !

[@thomasarussellsr]

Saved to my "tool builds" folder. Thanks again. SUB'd.

[@scottgutauckis4615]

Nice idea for a "hole less" circle jig. Think I will build me one just like that!.

[@o0Vion70o]

Nice! Now i can make round cyrcles without a houle in The middle 👌🏼👌🏼

[@pulpo439]

Muy Buen Video. *¡¡¡ BUEN TRABAJO !!!*

[@LenisPerezlenpe]

Just the type of circle jig attachment i was looking for my dwp611pk. Thanks!!

[@spicyhot1695]

Thank you Sir for this amazing video on these well put together jigs. The best I have ever seen. I am a new subscriber. Hoping to see more wonderful jigs coming from you in the near future. Thank you🛠️

[@pmdinaz]

fantastic!

[@gusnwosu]

Brilliant!. Just brilliant! I'll try to make it though it appears well above my skill level.

[@jup6401]

Why wasn’t this video recommended earlier to me? Absolutely loved it, well done sir 👍

[@hmorrisbenningfield1601]

Awesome video, put together very professional

[@robinmarwick1982]

Thanks Patrick, this is an excellent video...I like the way you use your drill press to place the threaded inserts, I've always found getting them square very difficult when done free hand...many thanks.

[@CornerfieldShop]

Really insightful jig Patrick, thanks for the video! Just discovered your channel and I'm a fan. Hopefully I can produce content as nice as what you are making one day. Really nice 👍

[@Diliverium]

Great video, subscribed!

[@benyaminhosseiny3198]

very usefull and versatilethanks.

[@br31woodlands69]

Wonderful video

[@jadi.arifderma]

I love your non-hole trammel. Thanks for sharing ⭐

[@TKevinBlanc]

Beautifully engineered (as all your stuff is). I mean, these are far and away the nicest jigs - from any KZbin creator - that I've seen. I want to make one where the end piece is reversible: circle cutting on one side, edge guide on the other.

[@mikeallan9574]

Excellent idea, and nicely executed too. In hardwoods, I find threaded inserts aren’t necessary. Just drill and tap.

[@amilcareposti2437]

in poche parole: BRAVISSIMO.

[@paddydunne774]

Exelent hack with the coke can shim. We used to pack worn swinging arm bearings on our MX bikes back in the late 70’s early 80’s exact same way. Even finer tolerance these days with the paper thin material. I’m embarking on making a large router compass to cut 300/400mm curves out of 18mm exterior ply for a shepherds hut roof for a shipping container 🤘🍀

[@antonio19664]

Bravo complimenti.👍

[@JohnSmith-ud9ex]

Sitting here smiling about a man that I understand and appreciate (coke can shims)... thank you once again, Patrick = )

[@braulioperez181]

Great project Pat! I''am in.
