Brass Fidget Spinner w/video (USB Microscope)

[markwisniowski]

I've been making a few spinners using brass lately, which I must say I like cutting over aluminum at the moment. This one is a smaller design using the smaller R188 sized bearing. 

You can see in the video that I have added a cheap pen-like USB microscope to help set the WCS X and Y to Zero. The bit I'm using is a 1/8" metal rod with the tip ground to a point. It's really helpful to get in there and see up close where the X and Y of the spindle is lining up. Once I set X and Y zero, I jog up on the Z and change the bit to a flat 1/8" 2 Flute and calibrate the Z height using the paper method.

Enjoy!

Very cool man. I like the USB microscope approach. That's a good idea.

Thanks Derek! I'm on the quest to mill both sides of a stock material so that they're the exact same on both sides. The USB microscope is getting me much closer...

What feeds and speeds are you using if you don't mind me asking? What program?
