Cutting with the scroll saw blade can leave fuzzy edges on the backside. These will be removed when the edges are rounded.
Changing direction with the blade can also leave rough edges, or sides that don’t meet perfectly in the tight V areas where the branches converge.
To smooth these areas, a rotary tool with a needle-type bit is used. It acts like a precision sander. For best results, this cleanup process is done from the backside with the tool spinning at low speed. The tip always has to be in motion when in contact with the wood to keep from creating a round indentation in the wood.
In next installment, the edges of the branches will be rounded.
