Cutting out another shape on the large Beverly shears. Notice the paper pattern that was traced over an opening, creased with my thumb then cut out.  The pattern was transferred to the copper sheet and right now a rough cut is being made.  After this, there will be about a 1" or less extended lip around the drawn line and this shape will be recut to the right size.   By freeing the basic rough cut pattern from the main sheet, I'm able to manipulate the curves to be cut a bit more easily and accurately.  The thin waste strip bends and curls easily under the blade of the shears.  If  I didn't do it this way first, the whole sheet would bind under the hold down on this particular shear.  It's usually a good idea to rough cut first then do a finish cut afterward.
