So after upgrading my 44T to a 36T and being surprised that it's not much of a difference I want to go even smaller. So I'm thinking I could order something and wait weeks or make my own 28-31 tooth sprocket for nothing. I could either find a proper width sheet of metal to work on or just use my 44T that already has center and mounting holes. All I really need is a proper size drill bit, and my trusty grinder.
Only thing is, how am I going to measure and get the spacing just right for the center of my 30 holes I need to drill out to create the teeth. I should be able to measure the distance between each gap and multiply by 30 to give me the circumference then I can calculate the radius and all that.
Sound good? Has anyone done this before or have Ideas on how to figure this out properly. I'd hate to drill out 30 holes and grind out a gear and find out I got the pitch all wrong! Maybe I'll make one out of cardboard first.
