I had no idea how to tackle this in FreeCAD. Your tutorial helped me out. Thank you!

Great! Glad it helped

This was a great tutorial, exactly what I was looking for. I'm also new to FreeCAD so this taught me quite a lot. The boolean operations blew my mind. Thank you!

I've been using FreeCAD for a while now. Started looking for a way to design a 1/16 bevel gear setup everywhere. Never got any idea how. You just gave me the means to do so THANK YOU very much. You also gave me a learning curve like the North face of the Eiger to get to the point of doing my own design. I'll first copy yours exactly. However, you showed me it is possible. Thanks again for a very nicely structured video.

1/16 is huge step with bevel gears in the real word I rarely see much more than 1/6 The ring and it’s shaft will have to be very rigid

@@jacquesfavre999 Hi Jacques, thanks for your reply. The large gear (preliminary teeth count 224) will be affixed to the bottom of a 60cm diameter display platter carrying a light load intended to slowly rotate and stop at predetermined angles. I'm going to use a fairly large diameter, single row, deep groove ball bearing (diameters: 17mm inner and 40mm outer) laid on its side instead of an axle for the large gear. The pinion gear will be affixed to a mounted 60rpm 12v DC motor with speed control. A question though. Is there a way to keep the pitch angle at 45 degrees for such a ratio? I've read the principles and they seem to require two complete cones with one pitch apex yet I cannot understand why the pitch apex of the pinion gear is not made to correspond with the side (equivalent in length/height to the pinion pitch apex) of a truncated cone of the large gear. The maths seem to allow for that but I've not seen it discussed anywhere. The only difference seems to the be that the large gear's diameter and teeth count becomes unlimited with a truncated large gear cone. The sum total of my knowledge on bevel gears, and gears, is microscopic however so I might have missed entire libraries of knowledge.

Only a ratio of 1/1 will be 45 degree For1/16 the angle will be in that ratio too

@@jacquesfavre999 Thanks Jacques. Unfortunately for me, this seems the only way to go.. ah well, reality does intrude sometimes.

Very useful and clear. Thanks a lot!!

Very useful. Thank you!

One hint: you an use the "reset_origin" property of the bevel-gear to have (0,0,0) as center of the cone. This helps with creating the construction of the geometry.

Good to know, thanks

Whats your.opinion on torque loss and speed Im trying to make a 3:1 Would bevel gears allow reduction with minimal power loss I want to rewind a clock as simply as possible

Awesome!!!! ❤️

Wow. Smooth

very helpful!!!

My only suggestion is to slowwwwww down in the beginning. I'm a fast dude and this was when a professional shows you how to do what they do and they fly through the steps. Good video otherwise but I definitely had some frustration. Also announce hotkeys if you use them. I struggled through this and merely slowing down and extending it to 15 minutes would have reduced my time on it from 5 hours to at least 2. For tutorials, it's worth slowing down. I watched at .25 speed for a good chunk of it and still had to play it several times. I learned a lot from your tutorial and still gave a thumbs up. It was a push, my experience is pretty limited with freecad though. To someone more experienced it probably isn't too bad

This seems fantastic. One problem , we with poor eye sight can not follow the very SMALL and so FAST pointer. If possible can you increase the pointer size and maybe to a red color. At least then it will not disappear. Thanks a lot

I am sorry for the speed, I want to keep the video short and interesting. Do you know that you can slow it down at your end? Do you have the quality setting on high? I did slightly increase the size of pointer, and black is what works best for me Thanks for the comment.

@@jacquesfavre999 The speed becomes irrelevant if the pointer is bigger. Thanks for your help.

Please sir can you make a video on how to use freecad to design a complete swashplate for 4 blades installed 🙏🏻🙏🏻🙏🏻

when I use the bevel gear option and change the height, the angle changes even though it is set to 45. This kind of confused me. Is it an issue with the workbench or the way I am using it?

I saw that too Happens when making a gear higher than what is possible Change to bigger module fix the angle But still a bug

Where do i get the gear workbench from? It is not in the workbench drop down menu.

It is an addon go to tool, scroll down to add-on manager, find and select the FC gear work bench, add to the work bench, restart freeCAD

that intro mann

That's great but it is far too complicated for me to grasp. I also tied the scad gear maker and that is also too complicated.

I'm trying to follow this tutorial with FreeCAD 0.20, and the boolean operation to cut the gear doesn't work. Any idea why this would be?

Sometime the order of selection makes a difference Recently I have experimented with creating a 3 rd body to house the Boolean operation

FreeCAD is powerful it can be overwhelming, at time the great thing with FreeCAD, you can always go back and adjust your design

Wait, what did you just do?!

Nice video! But way to fast! 😅

CAN YOU SLOW DOWN PLEASE !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks sir ..... but the speed was too slow. I had to watch it at max speed with lowest quality and still my toddler was able to see it. Thanks sir.
