| Cutting circles. |
A perfect circle is the most difficult shape to cut with a Dremel. It just makes more sense to use a Holesaw. Otherwise if you don't give in easy and wish to cut elaborate panel designs, master your circles! Then you can cut just about any design you wish.. Heres how I do circles. |
| Apply masking tape over the cut area. Tilt the cutting disc inside the circle line Hold the Dremel like this |
| Start Dremel at 15,000 rpm. Only increase rpms when confident you can control the disc. Use cutting disc to engrave one 1/4" long groove at a time around the circle. Turn the panel clockwise as you go along. It helps to have the panel attached to a box |
| Youre going to use the groove to guide the cutting disc. |
| Set Dremel to maximum speed Make the cuts about 1/4" Lean the disc against the inner circle to avoid cutting lines into the blow hole. |
| Heres the circle removed. Notice how the edge is angled down. |
| Use a rounded side file to debur the circle edge. |
| Masking tape removed. Not a bad circle for freehand Dremeling. |
