LOVE the focus on safety here! Well done - this tutorial makes the circle jig accesible and, most importantly, SAFE! Thank you for such a simple and informative video!
7:57 You gradually lift the blade in small increments to avoid burning. Start at the very bottom of the circle and do just about 1/8 inch. Then slowly lift the blade 1/2 turn at a time. No more burning.
Another simple jig that works Colin. It's amazing how many UA-camrs remove the blade guard. For 'photographic' reasons. You are one of the few who keeps it on. Thanks Colin.
This looks like a really nice way to make a perfect circle template to use in the future with a flush trim bit to make repeated circles without all this hassle going forward.
Great job Colin. It almost seems impossible to do to a common person not knowing anything about woodworking. How wonderful it is to have someone like you who explains it to us and show us too. Thanks for all you do.
I love your Rigid table saw. Had one at work. Retired now. Great jig as well. I use Klein metal runners for my jigs. A little expensive but so accurate
Thanks a lot, Colin. I glued up about 50 pieces of various wood (from Roasted Ash to Purple Heart, and Paduck, and so many more), all with a different density and hardness. I tried to use my router table for make it round, but the different densities made my router crazy and some of the softest wood broke where they should not have... Anyway, I re-glued the whole thing (not so much fun the second time), and used my table saw this time as you suggested... And it worked like a charm! (I actually used my crosscut sled) Thanks for this tip and for all the videos... you're an inspiration.
Nice video Colin. I am one of those guys that doesn't use a blade guard or riving knife. It's a personal choice but it also makes me be extra careful when woodworking. When I run wood through my saw that is the ONLY thing I'm concentrating on. I also use a push stick every time.
I traced a 40 litre bucket lid onto a piece of ply and jig sawed it out.almost a perfect circle.the problem was i needed a hole in the centre.It took me long a long time to find the centre of the circle.I would have saved a long time if i had used this method. Great video
Rangatira Ahau: The way to find the center of a circle is to draw 2 lines across the circle (not parallel to each other; close to 90 degrees is best), then find the center of each line and draw a perpendicular line toward the center. Do this for both lines. Where the two perpendiculars meet is the center.
Great video and easy to follow. I just beginning a business where I have to make a lot of circles out o wood, so this will speed things up! Thanks for sharing!
This works but can be dangerous. On one occasion I tried this, the blade caught the board and spun it so hard it nearly ripped my hand open. That sudden spin can also potentially thrust your hand(s) right into the blade if you're not consciously thinking about it. I still use this method, but it can be a little precarious. Also, I wouldn't try small circles - only large ones.
I would lean towards saying you should have taken more down during the straight passes because spinning it. But, you’re not entirely wrong either, this is a somewhat dangerous technique. I actually stand off to the side with my hands on the far side of the piece away from the blade. Awkward a bit because I’m left handed and am using primarily my right hand but it works. Also I keep the blade just even with piece so theoretically if you piece is pretty stable it should be pretty hard to touch the blade.
@@TheBestRoddy you think he's being annoying but there is a recent video of exactly this happening to someone doing this technique. That operator was lucky enough to have a Sawstop, because her hand was pulled right into the blade and she would have lost all her fingers had it been any other make of saw. Check around on UA-cam for it. I'm not a fan of this technique precisely for this reason.
Amazing how things happen, I posted this on Table saw Hacks and here you have built one like mine except I also use mine for cross cutting boards since the edge is at the blade. Biggest I have cut is a pair of 30 inch circles. Great Video
Nice job. I need to cut a 4 1/2 “ wheel. This seems to be the best way to do it. I have numerous routers but there isn’t anyway I can cut a 2 1/4 “ radius on any of the routers.
Nice work sir. I've read about how to do this in magazines and books but wanted to see how it was actually done. This is supposed to work equally as well on a bandsaw as well but I don't own one. In regards to the riving fence, I prefer to use them as possible. They are there for a reason. Plus, they push the sawdust down instead of into your face. Also, if you bring the working piece backyards into the blade, that is what causes burn as well as feeding it too slow. But thank you. I enjoy watching your work. I seem to learn something new every time I watch. 😊😊😊
Yes, this works 100 times better on a band saw. Takes all of about 10 seconds to cut the entire circle. Perfect circles can also be cut with a router, or a jigsaw and Disc Sander. All of these other methods take a fraction of the time, are probably safer, and produce a better result. Sorry, cutting a circle on the table saw is something I would never do.
@@bullfrogpondshop3179 Please show us how in your next video, would love to see your shop with all the expensive tools that a lot of us can not afford.
What I was young and debating my father he would try to impress upon me that things aren't always what they appear. He would say remember that a circle is nothing more then a series of very very short straight lines, this is a great illustration of that .
A little tip: To make SURE you don't have little 'plastic' debris balls form and mess up attaching the runners to your sheet goods, countersink both sides of the holes in the plastic.
Great idea, thx Colin. Correct me if I'm wrong, but it's a "fixture", not a "jig". A jig guides the tool, whilst a fixture guides the workpiece. Keep up the good work!
Colin, Would you address the issue of tolerances that can be generally achieved when working with wood. Your videos have been very helpful in helping me align my table saw, fence and create a crosscut sled if these are all aligned what tolerances can I expect when making cuts.
i almost died doing this, beginners beware the kick back is no joke. I didnt give up however i took a breather gathered the curage to try again and now i aquired a new technike.
It would be way safer and give way better results to use a circle cutting jig with even a super cheap router, or a decent jigsaw. A router table or bandsaw would be my go to if those tools are at hand.
Really great video! Thanks for posting! this video is really awesome and informative! Thanks so very much for a video that shows a great and safe way to do this!
What type of plastic do you normally buy for this at your plastic shop (not counting cutting boards here), assuming I'd like to purchase an equivalent plastic online.
@@darrenlaberee8036 It makes it harder to measure the pin placement for cutting the circle because you have eliminated the flush cut edge, but yeah, it could be done.
Ric Ferrentino At a certain point wouldn’t it be more wise to use a hole saw on a drill? Seriously a ROUTER with a circle jig is the proper method of cutting a circle.
At 7:15 you mark the exit point. Line up the marks and mark some tape on the saw table top to your left. pull towards you approx 2 inches and mark tape at leading edge of saw blade at bottom for start location. pull clear, start saw, go from start to exit in 1/4 in increments per full rotation of piece. No more black burns and blade deflection... :)
Your burn marks are due to the degrees of incremental distance in the straight cuts, which are larger than the radius of your ten inch blade. Make more cuts, to get your straight cuts inside of the 3/4ths inch height of the blade, (in reference to the cut board) then you will never have burn. The best (and by far safest) way to do this is with a snug, smooth bolt in the middle, and what you need is a nut to prevent the board from climbing, and a washer underneath the jig to prevent the entire thing from possibly riding up out of that hole. I'd make a slot using a router to slide the bolt to desire radius measurements, and two nuts over a large washer to lock the board down still allowing it to turn.
thank you for the tip..i like to build things out of wood and/or metal and i just learned something cool today...i could've used that trick a week ago(make a round piece of wood), but i'll definately use it in the future. and i also like the sliding jigg you made...thanks...lol ps..your experience really shows.
When you are in the final stage, rounding the circle, you should clamp the base of the jig. By accident, while putting your weight on the board, the whole thing may slide forward and you can cut your hands or worse.
If you do not want to put a hole in the wood you can use a strong adhesive tape to hold another piece of plywood to the main piece. The nail/dowel will go into that piece.
Colin, particle boards as a given, what dulls carbide blades most after it in your order? BTW, am now a subscriber, and you've shown this 60 year old so many new tips and tricks. ty
Carl Zorro. No because the sled had been cut already by the saw blade, therefore the edge of the sled is the same measurement as the tooth edge to the center of the circle. Much more accurate .measurement as well
Hello Mr. Colin, I have learned so much from your videos. Thank you so very much for sharing your knowledge. What is the piece of plastic that I ask for when going to the store? How did you determine where you drew your line on the base?
I like the concept however too dangerous in trusting the process with a nail, I would install a toggle clamp to avoid put my hands near the blade. Thanks for sharing that concept. Very usefull.
Great job on this video. Clear instructions, safety reminders, and explanation of your techniques. Bravo! Thank you.

Thank you Colin! I've tried and it worked brilliantly!
It looks a lot easier that I thought it would be to make a circle making jig on the table saw

Worked like a charm. Thank you sir.
Great Colin i made the jig and this afternoon and cut 2 perfect circles great video
Glad I could be of help. Thanks for watching!
You can also buy plastic cutting boards at the dollar store. They work well and rip easily on the table saw.
Yes you can. Thanks for the tip Timothy.
do you mean for the guide or for the entire Jig?
gnrsmith1 cut them up foy the guides.
lol I just picked some up

You could make a jig like or with a stationary or adjustable spinner. Like the ones used on a table for food. Thanks for your videos! Happy cutting :)
Mix some sawdust and some wood glue to form a heavy paste. It can be used like wood putty to fill in any holes. Sand after it dries.

GREAT video! Thank you!
Thanks a bunch...i cant wait to make this....im having a lil trouble finding a place to get the plastic cheap though....
Dollar stores, OR Bed Bath and Beyond.
White-poly cutting boards.
I have a large table saw sled I use to make circles. When you pull the sled back you can clean your scrap away.
Thanks for the tip David

I like it. A quick and simple jig.
Thank you
Very cool! Would you suggest trying to make smaller circles. I'm looking to make circles about 2" diam. X .75" thick.

Parabéns, vc é muito habilidoso com a serra circular .
Nice video Colin, I like the extra safety information.

Love your videos! Still learning with my saw, but you make the learning curve easy!
Keep up the chuckles cause it shows you love what you do!
Great stuff, thanks for the tips
I learn so much from you 👍
Thank you
Up to how big of a circle can you make. Eg could you make a 18” or 20” circle?
I can do that with my plunge router and my circle jig.
nice job
Nice. Learned something new, that’s good. Best wishes and thanks
🤔 now i know why it's called a circular saw😉 btw nice,simple and inexpensive jig.
What table saw u have?
How do you make a bowel jig for the table saw. I made one but it needs to be improved
Great.... your videos are so cool, clean explanation , and fully understandig for begginers. Thanks
You're Welcome, FREDBLA!
Brilliant, thank you.
i almost died doing this, beginners beware the kick back is no joke. I didnt give up however i took a breather gathered the curage to try again and now i aquired a new technike.
should mention the size limit of the circle possible ? I wanted to make one 26 inches.
U`re great...Thx, I`m gonna ask my friend to do this today....cause he`s got table saw and me have only circular portable saw...
What a great tip, thank you
Whow, really works thanks for this idea 👍
Are the plastic runners UHMW? They are not inexpensive here in IL. Sheets are upwards of $100 and two three foot bars are about $30
very good, I like all your videos.
You could use a bit if saw dust and glue to fill the hole
Hic!!!
Great video! Wondering if this technique can be used to cut a circle with plexiglass?
Would be better to try it on a bandsaw, if you have one, or a router. Plexiglass can be tricky.
just zip tie the anti kick back in the up position so you dont have to worry about them interfering and you can still use the blade guard
How do you know where to put the line on the big piece of wood please?
It would be way safer and give way better results to use a circle cutting jig with even a super cheap router, or a decent jigsaw. A router table or bandsaw would be my go to if those tools are at hand.
Very helpful.thAnks 😀

I could make wheels now for my boys kart! Thx !!!
You're welcome
Don't forget to use old bicycle tires to wrap the discs!!
thanks friend for sharing that good technique.
Thank you very informative
Where did you get the plastic from in this video for your miter slots?
Colin, is the plastic the super slick type or just plain plastic?
The plastic he is using looks like UHMW which is a excellent choice for this application.
Really great video! Thanks for posting! this video is really awesome and informative! Thanks so very much for a video that shows a great and safe way to do this!
What type of plastic do you normally buy for this at your plastic shop (not counting cutting boards here), assuming I'd like to purchase an equivalent plastic online.
Nice! Old school.
good job
Thanks
would the measurement of O.D. of the circle should it be to the blade?
You should be able to temporarily disable the pawls with a small dowel and a rubber band or cable tie. You just wedge them open and tie them off.
Could you not trim your 3/4 ply to be outside of the pawls?
@@darrenlaberee8036 It makes it harder to measure the pin placement for cutting the circle because you have eliminated the flush cut edge, but yeah, it could be done.
Excellent, thank you. How small a circle (diameter) do you think one can safely cut this way?
How close do you like your fingers to the blade?
Ric Ferrentino At a certain point wouldn’t it be more wise to use a hole saw on a drill? Seriously a ROUTER with a circle jig is the proper method of cutting a circle.
Did they not have a saw blade made for cutting circles. It was in shape of a yield sign. Do they not make them anymore.
Where can I buy this plastic for runners?
