> yoyo together. Grabbing by the rims, try to see if you can bend the yoyos
> hub (if you push in and out at the rims, and the yoyo remains strong, you 
> haven't gone too deep). If you do however go to deep, your yoyo may break
> if it comes in contact with the floor (oops, personal experience).

> 4. If you are planning on a first time recess, here's a helpful tip for keeping it even:
> Don't cut with a whole saw; the yoyo should be spinning, not the cutting tool.
> That way it will make a perfect circle if your dremel, drill, drill press, or lathe is 
> secure. Secure the yoyo by the axle in the chuck of the power tool (unless using
> a lathe), then secure the dremel/drill in a vice to keep it from shaking around. 
> Then slowly cut into it with a corkscrew, chisel, etc. Hope this helps.
