Too much RPM will be your problem. Think in inches/minute, IPM, that is the number of inches per minute that pass under the cutting tool. If you use a router to do the cutting then you will probably be in the 300 to 500 IPM range. If all you want to do is turn the exterior round then use a variable speed motor to drive the rotation. Look at my site, turningaround.org, and email me if I can help. |
