Making gears that run smooth at a right angle by beveling the teeth. More on making these: woodgears.ca/ge... Using my gear program (which I wrote, and which I sell) woodgears.ca/gear
Matthias, I noticed that both gears have an even number of teeth. If you think of the Dutch windmills, they work with gears too. But one of them will always have an odd number of teeth. This results in an ever jumping position, so that no tooth will be worn faster than the other. Specialy working with wood, the wear on a single one can result in unexpected and unwanted effects.
Just an odd number doesn't help much. If both have multiples of 3 for example you will still end up with some teeth never ever meeting. You need a prime number of teeth to "mix" the all.
superdau Actually, the criteria is "relatively prime". 9:10 would meet the criteria, even though neither is an actual prime. But for a gear toy, it doesn't matter much.
Maarten Happel I should have specified more accurately and Matthias spelled it out already: the important thing is that the two gears don't have any common prime factors ("relatively prime"). There's no difference if the number of teeth on one gear itself is prime or not.
I love watching you chisel, you're so quick and efficient! Haha I honestly have no plans to ever make wood gears but watching you work (or mow lawn) is inspiring!
Nice stuff, but how can you ensure that the hole for the shaft is drilled exactly in the center? I mean even on the drill press i can't be sure enough that the holes are are exactly in the center in both sides...
***** There's a method that i use. It's a bit tricky but it hasn't failed me. You drill your hole in the wood. Whatever size you need, you do that first. Then, you get your template and the shaft, ball bearing or screw and using that, after you've cut a neat hole in the template, you then glue the template to the wood. If you're careful about it, you get very little issues with it.
Matthias Wandel I think Johnny is talking about a hole not being exactly vertical, even when using a drill press. I have the same problem when I use a drill stand (don't have a drill press), but in a drill press it could be that the table is skewed.
Matthias, my idea is that if you want long life gears out of plywood, you can use wood stabilization technique. It can be little expensive, but if you want heavy duty gear, that will work fine. Especial on cheap plywood.
Maybe for next week's project you could build a more permanent jig for the bandsaw table that would allow 'negative angles'. I bet any number of your viewers have the same difficulty - either with bandsaws they built or with commercial bandsaws. They can tilt right but can't tilt left. Just a thought...thumbs up my comment if you think this would be a good future project for Matthias!
In your video on making the screw jack, you mentioned the pressure angle is 14 degrees. That happens to be the same angle as a common dovetail router bit. Could the bevel gears be cut using a dovetail bit and a guide bushing with a template? The template need only be for one tooth and indexed around the circle. The CNC guys could also use a dovetail bit instead on a ball nose.
If the width of the teeth is about even in the middle of the tooth, then they should mesh on the same plane if one gear is flipped over so the wide part of one gear's teeth fall into the wider gap of the other gear's teeth. Theoretically.
Hello Matthias! Your videos are great for sure are the web's best. I have learned a lot from them. Your website is very rich, full of important information. I live in Brazil and here is no common build wooden houses. But I'm thinking about build my own house. You know a site that has housing projects? Excuse my English. Big hug and wish you much success.
I never thought I'd comment on gears, but they sure look nice. you need to use the gears to squeeze glue, cause apparently the last video didn't have enough glue for everyone
3:20 like didn't expect that would happen when i was young i would always wounder what could i put in the drill chuck i started watching this series on the discovery channel called gold rush and after about 1 season i tried to make a shaker deck and i used a drill to make it shake it didn't work well but it was fun :)
Mathias Your gear generator program is great, have had it ever since you come out with it, thanks for all the continued updates, even when not making gears , it is useful for segmenting a circle, any chance of a addition in the near future of adding a spiral program to it? would be useful in a lot of different ways , Thanks for all the videos ,very Much appreciated
Do you think using beveled router bit with a reduced size gear as a template could do the job easier? I'm about to start experimenting with some right angle gears in a puzzle box.
Wow, great design and looks fairly simple to cut (on a bandsaw at least). Do you have a special set up for sharpening chisels or do you just use a belt sander or something?
Çevirmeli balık makarası yaparsanız, çok memnun olurum, saygılarımla. I would be very pleased if you could make a fish reel with a dial-up. Kindest regards
The use of baltic birch may not be obvious to some viewers. Normal plywood would not have the qualities needed to make these gears, since it is much less stable and can even have voids, further reducing the strength of the gear and causing snags in the meshing.
Stable enough, and you can just use a patch without voids, or fill the voids. The voids wouldn't impede functioning anyway. You absolutely don't need baltic birch for this.
Hi matthias, I am ian i am new in cad modelling I faced a problem when i make a 3d mechanical toys I use Autodesk Inventor student license, I make the gear with power transmission generator I really want to make my gear more beautiful with round edges but if I make gear manually I worry it will stuck could you give me a sugestion thank you
Hi Matthias, that looks like an awful lot of work for just two gears... Isn't it possible to make a small jig for your pantorouter so you can use a small routerbit?
Matthias Wandel 3d printer. I for days am printing gears and just think how many steps are needed to make them in metal traditional way. This 3d printers are getting very easy to use. I found also great program for cad its called OpenScad and i am blown away with how many gear scripts are out there. Check it out!
Matthias, Couldn't you get closer to a true bevel gear if you cut them so that the blade always angles away from the center of the gear? I recognize that you won't be able to make them as quickly and you might have to make a jig to achieve consistency or even the more extreme angle required but you'll end up with teeth that don't taper to one side. Instead, the trough (or whatever the low spot between the gears is called) is beveled. It would be interesting to see you try this. If anyone can pull this off, you can.
Do you have a recommendation for a large format printer? I always seem to end up buying the slowest, most high maintenance and generally annoying printers.
Michael Stephenson I just use a printer that cost $50. And if it doesn't fit on one sheet, I go across multiple pages. The gear program does this automatically, for other stuff, I use my BigPrint program.
I always hope for a Matthias Wandel video when I open my sub box. Would you consider creating an online gear generator with JavaScript? I would be more than happy to chip in.
Matthias Wandel I had a look at that before I posted, thought a JS application would be more versatile. Would love to use it on a tablet for example. You could even use the same code for a cross platform desktop application. What's your opinion?
Hi Mathias, I need some costume gears done for a camera follow focus gear project, can you do them or do you know where can I get them. thank you in advance
Thought about that, but that would be an awful lot of programming, and even with a ballnose bits, it would take a crazy number of passes to get the shape. Bandsaw is much easier.
Matthias Wandel I'm not familiar with your program, but if it can export dxf files? Now for these sorts of gears, I suppose the program would have to be entirely re-written to work with 3D models, in order to export stl files. Not having a CNC I don't know what tool chain one uses for 3D structures, though I'd think it a similar process as 3D printing. 3D modeling software -> stl -> slicer program -> gcode -> CNC machine
dumle29 The print feature will spit out a vector art of the gear, a lot of laser cutters can act as a vector printer to directly make the gear or you could print to a pdf and then convert it to some cad friendly format with CorelDraw or whatever your favorite vector drawing program is.
dumle29 That doens't help in the passes needed. To get an angled surface it has to be done in many separate layers, each one talking a little less material than the previous one. Or you have to do an aweful lot of sanding, which in the end will result in differently shaped teeth again and defeat the whole purpose of CNC. But in one thing I agree: Seen the work involved in making gears, I'll never make wooden ones myself, angled or not.
superdau Nah I mainly meant CNC for flat gears could be nice, and time is of no concern with a leave and let go CNC, Wouldn't mind having to sand them either (Mathias does so in the video as well, so it's not an additional step)
Matthias, I noticed that both gears have an even number of teeth. If you think of the Dutch windmills, they work with gears too. But one of them will always have an odd number of teeth.

superdau Actually, the criteria is "relatively prime". 9:10 would meet the criteria, even though neither is an actual prime. But for a gear toy, it doesn't matter much.
Matthias Wandel Prime's will do the best if used for a long, long, looooong time.... But 6:19 would work fine too. Just as 9:10.
So the rule is: the second gear must be multiple of the first one, and then add 1. In this way 9:10 and 6:19 meet the rule.
Maarten Happel
I should have specified more accurately and Matthias spelled it out already: the important thing is that the two gears don't have any common prime factors ("relatively prime"). There's no difference if the number of teeth on one gear itself is prime or not.
That is a great new feature. Looking forward to using it.
Your creations are like from a childhood fantasy

I don't know how you do it, but I'm happy you do. It is so fun to keep learning from your pursuits.
Like others have said I always look forward to and enjoy your posts, even if I am never going to make what you show. Just the learning is fun!
Thanks
Nice stuff, but how can you ensure that the hole for the shaft is drilled exactly in the center? I mean even on the drill press i can't be sure enough that the holes are are exactly in the center in both sides...
I punch a divot on the X in the middle with an awl, then let the point of the drill follow that.
Matthias Wandel Ok thanks;) This is pretty much what i do, but unfortunately there is always a misalignment, making the wheel wobble a little..
*****
Sometimes I have to re-punch the divot if I didn't get it exactly in the middle. But a tiny amount of wobble is normal for me too.
***** There's a method that i use. It's a bit tricky but it hasn't failed me.

Excellent, I was having trouble with the gears on the box joint jig. I'll give this a try and see if it makes a difference.
I have been looking into building a jig to make bevel gears. I may now forget about that and use your gear generator.
Thanks

Thanks for the upgrade to the software.
This is awesome! You can make a spinning wheel for pottery!!
WOW,i make elements like this with cnc machine and you make it with your hands,awesome!!!!!!
Very informative and not a Micro jig Gripper in sight.
Thank you! I will be updating.

Brian Taylor If you like lots of airborne dust and smoke, then possibly. But a bandsaw is faster and easier.
If the width of the teeth is about even in the middle of the tooth, then they should mesh on the same plane if one gear is flipped over so the wide part of one gear's teeth fall into the wider gap of the other gear's teeth. Theoretically.
Genial su proyecto Matthias, gracias por compartir.

Thanks. The program looks really cool and easy to use.
Looks much more beefier...NICE!!!

Cool. What next, a manual gearbox? A differential?
Do you think using beveled router bit with a reduced size gear as a template could do the job easier? I'm about to start experimenting with some right angle gears in a puzzle box.
all of this is good but what is the point where the gear can not handle, the stuff broke at 160 pounds, what is the limit of the gears?
Wow, great design and looks fairly simple to cut (on a bandsaw at least). Do you have a special set up for sharpening chisels or do you just use a belt sander or something?
spinafire Just free hand on a white wheel grinder.
what varnish do you use?
Do you you think this would work for transferring power for on a mower engine to the rear wheels of a go cart. Will they hold up to the torque?
I just can't think of a creative comment! A W E S O M E! Thanks
So worm gear next and then synchromesh gears as the final challenge?
You are a god amongst men.

The use of baltic birch may not be obvious to some viewers. Normal plywood would not have the qualities needed to make these gears, since it is much less stable and can even have voids, further reducing the strength of the gear and causing snags in the meshing.

Is it possible to make a rack and pinion drive in gear generator?
Good job, thanks for inspiration!
Good morning, what angle do you use to cut the gears?
You need a hypoid gear set !

How close are you to using your router tenon jig or your pantorouter (both with an attachment) to cut these gear teeth?
Doug Parker The bandsaw is the best tool for the job.

When you say varnish do you mean varathane, or an equivalent water soluable product?
Keith Wilson I use a water based product. The floor varnish is quite hard and slippery
Amazing.
Smooth running

Wouldn't reducing the angle have the same effect?
You need an angle on the teeth, otherwise they don't mesh very well.
Yeah!
You can try do them on your pantorouter
How are you liking the raspberry pi b+?
Do you use some kind of wax on the gear tooth surfaces for lubrication?
I put some varnish on that's fairly slippery (like I say in the video). Wax would help too, no doubt, but I haven't tried it.
what is the name of that liquid u put on the gear to make it slippery ? i couldnt hear you clearly when you said it in the video

Hi Mathias, I need some costume gears done for a camera follow focus gear project, can you do them or do you know where can I get them. thank you in advance

Where do you buy your plywood? I assume not at the big box store. Where did you buy it in KW?
I used to buy it at Home Depot. But look for a hardwood store (I know KW has one, somewhere in the south of Kitchener, but I don't remember the name)
Cool, thanks for the tip. And really? You could buy baltic birch type plywood at home depot? Maybe I'm just not looking hard enough...
Un crack Matias.
How about setting it up to create a CNC file to cut the angles.
