Do folks have experience trying to make their own plate sprockets or gears on a router?
What is your preferred source for the model?
What size cutting tool do you use?
Are you able to cut small #25 sprockets, or only #35 ?
Do you create a toolpath to taper the face of the teeth, or do you just grind/sand that down later? Or, do you leave it as is for a thin enough material?
What are the different tooth sizes of sprockets or gears you’ve been able to create and use?
For reference, we are using an Omio X8 and currently only have a small variety of cutting bits.
You can definitely cut #25 sprockets but you need to wear them in based on material thickness. Not sure I’d put a big load on them though? We’ve done this for a turret once. The tapering was done with a file after and then just running it in with a decent amount of lubricant.
We also did a 12DP geared turret once as well. That worked too… don’t recall the bit it was cut with but it was small and took a decent number of passes. Also did a fair amount of wearing it in before running it on the robot. Didn’t take much though… hundred-ish rotations. Turns out in the battle between a steel gear and an aluminum one, the steel one wins over time.
During the off season we had we created a version of 221’s double sprocket (#25), but it was done by one of our sponsors/ mentors outside of our build space (no access to machines during off season really). They have run fine but we havent ran them through a season.
We are talking about a rack for a rack and pinion, since the teeth profile came out a little rough on a waterjet (partially due to rush job and no gear with sponsor to compare teeth profiles).
