Vibrating cutter tool circular cutting jig
First Claim
1. An apparatus for cutting an approximately circular large hole in a sheet of material, comprising;
- a cutting tool which employs a flat cutting blade, a pivot post which is attached in the center of a portion of the sheet of material which is going to be cut out, an adjustable sliding arm connected at one end to the pivot post, the adjustable sliding arm being connected at the other end to a blade holder, the blade holder having an elongated slot passing through the body of the blade holder, the long direction of the slot being approximately perpendicular to the direction in which the adjustable sliding arm can be adjusted, the blade holder having provision to fasten the cutting blade into the slot such that the flat of the cutting blade is approximately parallel to the long direction of the slot, and the pivot post allowing the blade holder with cutting blade to rotate in approximately a circle at the end of the adjustable sliding arm, thereby defining the circular portion of the sheet of material which is cut out.
