I'm trying to make a clock, and for the escapement I need a large spur gear. I would like this to be made out of metal. Hand filing the teeth is one thing, but how the hell do I actually make a gear blank that large? Just getting a gigantic plate would be prohibitively expensive.I have all the tools that a regular blacksmith would have available.My first idea is to forge a groove into a length of stock, then forge weld it together to form a loop. Then I'd be able to fit a cross beam type deal into the groove. But I'm not sure if this is a good idea.

>>2891405are you retarded
>>2891395Can't you just use a plate?
>>2891395Can you be more specific, like what material and dimensions do you want.Plates of steel are extremely cheap if you're buying from a metal recycler. If your main concern is price then go that route.If you aren't able to drive to a metal recycler nearby, try ebay. If that doesn't work, I'm sorry, you're fucked.
If you don't know how to set up a tooth cutter in a mill, this project is above your skill grade.

Use a servo for the inverted pendulum and play physical modeling synthesized ticktocking in a speaker. It'll be best if they aren't quite synchronized.

>>2891395For escapement in general and when using a grashopper in particular, it is absolutely crucial that the surface is super smooth. If not, the escapement will get stuck and the entire thing will lock up. If you are new to this, and I guess you are, I recommend you get the feel for this by first making a wooden clock. You can buy plans for this on the net complete will full descriptions.
