- Sorry it has been so long since I last posted.
This project looks hard at first, but once you have the sled and practice a few, it soon becomes intuitive, and then downright easy. I would have liked to include much more content and detail into this video, because I really loved this project. You probably understand that most people tune out pretty early, and they just want to see the punch-line. For this reason, I try to streamline videos to their most essential and relevant information. I hope that I didn't leave out too much in this case, because let's be honest, this one was difficult. It looks easy enough in the finished vid, but there was NO information on the interweb for this one; I had to develop this method entirely by my own tired and stressed brain. Please try to appreciate how difficult this video was to make- I spent a week of my spare time doing star-related geometry and trigonometry in order to come up with a somewhat simple solution to this problem. I included only what I thought were the things that I would've loved to find when I first googled "how to make a wooden star."
Anyhow, I'm done complaining. I promise that I will be making tons of vids starting early this summer. I have way more ideas than I do time presently. Please try to enjoy this one in the meantime, and as always, thank you for your time.

I've been watching a playlist of your videos for about 45 minutes, amazing tricks in every one. and there is always something to smile at. Thanks for sharing your workshop and knowledge.
GREAT video and inspiration. I watched it this morning and spent a couple hours today building the sled. After a bit of frustration getting my head wrapped around how to turn each piece for cutting I made 3 flat stars, beveled ones are a project for tomorrow. I used your math to make a CAD drawing of the triangle, printed it out, and transferred it to the sandpaper. Once I cut out the paper I glued it to the sled and used it as a guide for installing the cutting blocks.
This is just beautiful in every respect!
From defining the 3D geometric challenge and analyzing the problem, through your clear exposition of the trigonometric solution, with a simple algebraic cancelation of sines... to the realization with that clever practical jig and using straight-grained wood that accentuates the star's geometry... Superb! There's a wondrous universe inside your Brain buddy!
THIS IS THE ONLY VIDEO THAT CAN EXPLAIN IN DETAIL IN MAKING 3D WOODEN STARS, THANK YOU FOR SHARING.
Thank you for making this video. I love it when someone makes a jig instead of hawking an expensive product most of us would only use once, if we bought it.
This is absolutely brilliant and thank you for taking the time to figure this out and explain it so eloquently. Will definitely be making this sled.
As a math tutor and a wood working hobbyist, I LOVED this video. Great job showing the math to the side lengths. Pinned this to my favorites!
John Howell why not keep it simple! 3 x Tan (72) = 9.233 easy steps in Roof Carpentry.
Great video. Going to try and make a bigger one with a bandsaw and that jig. Thank you for breaking it down so understandable that a child could follow your instructions. This should be a project in high school wood shops, if they still exist
Your projects make me feel like a kid again. Thanks.
I appreciate how you showed the steps to solving the math involved here. I've been driving myself nuts and burning through a lot of wood trying to figure out the correct angles. This will help a ton with my appliqués I use for my rustic furniture. Thanks!
Great. I'm glad it is helpful. This method will serve you well for a star against a flat piece, like on a piece of furniture. Once you figure it out and make the sled, it becomes super easy. Good luck, and let me know if I can help you any further.
A more than outstanding video! Precise and to the point with a calm approach!
I was pulling my hair on the math. I got it the first time watching this video- I know where I was going wrong.
I've been woodworking for 40 years or more and just now I decided to make 3D stars- go figure.
Great respect for the materials in every of Ur videos, minimizing wastes. Respect!
Back before computer cad , us older tool makers would sit at our benches for hours figuring all our dimensions for making punch and die sections. Someone would walk up and ask a simple question and it was like a punch in the gut tryin to wrap your brain around what you were doing again.
Brilliantly explained in this crisp build video. Thanks
if this guy was a boy scout they would give him a merit badge for multiple reasons. who couldn't appreciate and marvel at this demonstration. ya might have view it more than once since it is loaded with information but unquestionably, a GREAT VIDEO !
You are very welcome. I'm happy that you liked it, so thanks for letting me know. This one is one of my favorites.
Great job. Been looking/thinking about wooden stars for a while. Thanks.
I kept trying to think of a way to calculate the cuts by using a miter saw. Your sled eliminates all this. Good job.
Great video inspiration! Pretty beautiful work!
Thank you very much for the express class on geometry. We get so busy with everyday tasks that sometimes we forget about these basic things we learned in school. Amazing work! Congratulations!
this is a great video with showing how many maths is actually involved in making woodworking projects. Thanks for sharing
Mrhangerman Imagine and Inspire The maths is one sum Let’s keep it simple! 3 x Tan (72) = 9.233 that’s from an old roof carpenter
Most excellent thanks, a great way to combine my favorite subjects of woodwork and maths. . Well produced and presented.
This is the best star instruction video i have seen yet, thanks.the math is a little beyond me.
PixelRick The maths is one sum Let’s keep it simple! 3 x Tan (72) = 9.233 that’s from an old roof carpenter
I appreciate it. It seems that we share some similar interests. I really liked the work that you did with tetrahedrons. Thanks for stopping by ;)
I typically use (and recommend) a 24-tooth 7.25" Freud Diablo for general purpose. I also keep a 40-tooth handy for special purposes. The 24 is usually under $10 and it has nearly the finest kerf I have seen. Home Depot carries it; obviously it is the bright red one.
You are a star 🌟. More fantastic content from an amazing channel.
The age old question in math class of, "when will I ever need to use this in real life?" has been answered. Shit... I should have paid more attention!
LOL! Yeah ok - so there's 1. And it's a choice. Should have spent more time on how to invest properly for retirement etc.
Doesnt matter because this video is a better teacher on the math process than any actual math teacher in school.... you can learn ANYTHING online. As long as you have the drive to seek out this knowledge, college is a waste of money
Never too late to learn! I'm 51 and studying GCSE maths in night school. Great fun!
Brandon Kitchens Let’s keep it simple! 3 x Tan (72) = 9.233
Thank you for this. Admittedly, I just came for the angles and measurements of your jig. While I did learn your awesome process, I also get the sense that I am LOT less educated than I thought.
Beautiful!! Really nice work.
WOW. Love it, now to try it. Thanks for the info
Thank you for uploading this tutorial plus the math lessons. I'll give you a thumbs up for your neat work. My dad would really appreciate this tutorial, being a carpenter and a math Wizard. However, I"ll pass and will go to Homesense to pick up a star to decorate my shelf.
wowsers -- geometry - it's been soooo long. Who would have guessed how useful it can be.
Wow you did such a good job with the grain patterns
WOW... You're videos have always been good.. This is a whole new level. Great use of technology and math. It is obvious to the audience that you really know your stuff. Keep up the good work. I check out your videos on a regular basis!!!! Charlie
Thanks so much for your. Response. I'm amazed at your work. All your videos are great. I'm new to wood working and really want to make this star.
you are the best ever.
love this project and really love the way you are thinking and doing
thank you very much
I haven’t heard sine for almost 45 years, my math teacher would be proud! Nice job!
Best video available ! Hands down 👍
DUDE!!! you just made yourself even more awesome!!! thanks for that man seriously
Great video as always!
I found the math to be a very entertaining portion of the information and that part about getting more sure placement of parts by using math, well that is like a ray of sunshine. I will be looking to us that type of thinking in a future project. Thanks for making the sun shine, lol.
Yep, my sister lives there, so I should probably send her one. I really liked the math part, but this is probably my favorite video. Maybe because I had to scratch my head so much to make it. There was a lot of math involved that I didn't include, because I get the feeling that it bores most viewers. Thanks for watching and commenting!
I'm glad that you enjoyed it. Thank you.
I made a couple of stars and they were ok, but not perfect. After watching your video I got some serious info on the technique of the angles needed. Can't wait to make that jig. Thank you very much.
Great. Let me know how it goes.
Well done! Great vid.
Great job explaining. Now Joey pay attention and you can do it like this gentleman did!
Would you be able to have downloadable dimensions of the sand paper you have on your sled?
Just like you did on you plant holder video....
Much appreciate your videos....Thanks!
You have so much skill for this I love you videos
Woah! It's really cool to see you go into so much detail on something :) Also, when did you stop using the Matthias style push sticks?
Great teaching.. I was nerding out on the math.. Love it
This is my favorite star of all.... Somewhere along the way I can't get my 18 degree blocks lined up properly. I think I'm going to fabricate a new sled maybe it's a bit big for this project. Any thoughts on this?
wonderful. the ending with the cuts and music reminds me of Twin Peaks a little :)
Thanks, those are very good instructions!!
This gives me thoughts on how to make 3D crosses for Christmas presents. Thanks!
That was awesome Pocket!!, and now I can make some stars.I loved the way you matched the grain in the wood to make............I don't no like infinite little stars. It felt like that to me anyway.
Thank you, and keep up the great work that you do because people will learn a lot from watching them. I well anyway.Kevin.
Thanks, MrChris. I am glad that some of us out there enjoy this stuff. I think many will find this one tedious or boring. And sorry I made the message too short (I couldn't get it either).
I once heard a mathematician say that he became good at it because he was lazy. I kind of agree with that. I don't know all of my times tables, and I am not good at memorizing numbers or angles, but I like to know enough math techniques so that I don't have to memorize. Carrying around the solutions to all of life's problems would be a lot heavier than just carrying around the ability to solve them ;)
OK I have a question. You say the first cut on the guide is 18 degrees, then you mount the piece at an angle. How does this not change the angle in relation to the blade?
I love these videos and all the maths.
Awesome vid!!
On the subject of sizing the stars. A 1" clearance from the blade kerf to the alignment blocks gives a 6 1/8" star. So a 2" clearance gives a 12 1/4" star. And a ~5" clearance would produce a ~30" star. Practicality not withstanding.
Alignment block left > 1" clearance blade Kerf 1" clearance < Alignment block right
Nice!
I think the subliminal message in this one was revealed when immediately after I watched it, I did a Google search on why people put stars on their houses.
Planning a 12-point star for a clock. This showed me how. I can't thank you enough.
That would be beautiful. I haven't thought of that. Hope it turns out well!
i absolutely love this video
I really enjoyed this video. Not much info on the Web on how to make a 3d star. Much appreciated.
You are certainly welcome. I hope it works out for you!

Thanks for share your knowledge ! God bless you !
Great video, very well done.
You are so amazing. I’m enjoying all your videos . I’m fascinated with wood works and I’m learning loads more from you, keep it up ? Thanks
Thanks. I really appreciate that. Glad you found some of it helpful.
like it, very useful. Thanks for sharing!👍💪
I liked the video a lot! Nicely made video and very good project.
What saw blade did you used? Looks like very think kerf.
Well Done!!
Interesting stuff. Thanks!
Deep. I just did 360 degrees divided by 5 = 72. Each finger has two parts so half 72 for 36... Maybe I'm too simple minded. I didn't care about the angle at the point. My only concern for angles was where they joined. Equal length took care of the points. I do like your sled though. Thanks for sharing.
i loved it and learnt from you math solution fantastic i love it when the penny drops on something!
Beautiful 2x4's you started from!!! Seemingly straight and Not a knot in sight. The 2x4's at my local store as aee knot riddled twisted cupped and bowed, usually with some visible wane
You are perfect as usual
GENIUS!
Great vid. Thank you!
That was a good one. Thank you.
Great vid really entertaining
beautiful!
I'm a little late to the party but thanks for the vid and clear explanation. Thumbs up and subscribed.
How did you determine th angle to create the "angled" stock?
here I am 2 years after your question and pushing a decade on the original video, and I can't work out that angle either.
Yep..I won’t be making any of these stars anytime soon. Thanks for the video. 👍🇺🇸
All the more reason to watch again and practice it. It becomes easy after awhile, and it makes you a better carpenter... everything in carpentry is triangles. If you do that problem ten times without looking, you will never forget how to do it.
I'm so fascinated with woodworking, trying to teach myself now that I'm retired. This video is very helpful, but I need to brush up on my math. It's been over 40 years since I've used geometry.😂😂😂. Any other tips or resources will be greatly appreciated. TFS
you've gone way beyond the layman's terms of wood working 😊😊

Do you have any tips or tricks for making the sled and placing the blocks in the correct place? I understand the math/ratio tutorial, but I am curious how to actually place the blocks so they are perfectly angled and perfect mirrors of each other.
Sure. I stripped this video down a good bit, to prevent it from being too long.
The first thing that I would do is make a sled with a single cut in it, so that it is "zero-clearance." I would recommend using a thin-kerf, 7 1/4" saw-blade, so that your cuts are nice and thin to begin with. Next, just measure out your triangles on each side of the saw kerf, using the edge of the kerf itself as the "b" side of each triangle. The blocks are placed along the "c" side, so draw the triangles with a nice, precise pencil-line, and just use short drywall screws to attach the blocks from underneath, so that you can reposition if needed. Spray-adhesive on the blocks will make it easier to make micro-adjustments by reducing sliding around. In order to tell where the blocks end, it just depends upon the thickness of the star stock that you are using, so it may require experimentation. Oh, the sandpaper is just stuck with spray-adhesive. If you need more specific help, just ask. I can always give you dimensions, if needed. Good luck.
You explained the math very concisely and if you didn't cover it, someone would ask how you worked out the angles.
I wouldn't be one bit concerned about the thumbs down. There's about a 10:1 ratio, one idiot to 10 non-idiots, so you are bound to get a few. Idiots like clicking that button, it's easier than thinking or writing something constructive.
I made a small one of those by hand out of a single piece, carved and shaped it with chisels, rasps, files and sandpaper. It's about 2 inches tall when standing on two of the legs.
Good stuff.
thank you, very useful and practical
Marvelous.
I love that you love it. Thanks for continuing to watch.
Just an FYI: Harbor Freight sells an aluminum caliper that is 24 inches long. It measure in fractions of an inch down to 1/128's which is .0078125 of an inch or .198438 of a millimeter.
Awesome!
My only question is what angle is the stock cut at prior to all of the compound cuts?
See 6:35.
How do determine the distance of your angles from the blade? I want to be able to make different sizes of stars so maybe a groove in the sled is the way to go but I'm unsure about which direction it would need to slide (horizontal and/or vertical). Please help. I have been watching your video for weeks and building a little at a time. The concept has been very difficult for me to grasp. Thank you.
Be patient. This is some pretty confusing stuff. Once it clicks for you, it will seem easy, because we often become distracted by all of the non-relevant information at first.
Those angled blocks on the sled were placed where they were based on the stock that I was using. So, their size and placement depend on how big the stars you want to make are.
Lets say that you just draw the blocks on your sled first: this way, you can make the imaginary blocks go all the way to a point (at the sled's kerf). Now you can just place a piece of your scrap stock on top of it to see how much material you will have to remove. Just trace it. Do the same thing for how much space you will need to keep away from the sled's fence. If all else fails, try to approximate the proportions of my sled to get it close, and then make adjustments by trial and error.
I can also give you dimensions if you need them. I want to help! This is not beyond you. Again, be patient. Sometimes our brains just need time to adjust to new ideas- I know my brain did!
@@pocket83 if the offer still stands to get dimensions I'd interested in comparing them with my sketchup work. no prob if not.
Good instructions my fellow carpenter it's all math and its in our carpentry tools but gotta use the brain to make it work.
Thanks for sharing
Very good.
