I know I am making a mountain out of a mole hill, but is there an easy way to trim an already cut circle smaller?
Basically, I purchased some 30cm wooden circles (3mm thick) , and I need to adjust the size to 26cm (cutting only 2cm) however, when I think I have setup correctly, and used the frame, it appears the frame is eclipsed, and I am struggling to find a method, can anyone assist or give me any pointers, or is this just moving my project around the bed until I get the size I need?
Thanks
There may be variations of this method, but it’s a straightforward process, in my alleged mind.
Set a piece of scrap wood, cardboard, or other throw-away material on the bed. Cut the 26 cm circle in the scrap, then use offset and cut the 30 cm circle in the same location. Remove the cut pieces and place each 30 cm in the jig. Undo the offset and each circle will be in the correct location.
Get comfortable with making a jig to make job repeatability easy. FWIW recycled amazon boxes (who has those?) make for great jig material. I have an index location on my waste board that I use to line up a backer board (scrap wood with a square corner for alignment). I staple a sheet of scrap cardboard on top of the backer board. Cut an outline of my target (wooden coasters are a good example) - adjust the size until I have about .25-.5mm clearance. Once the outline is right, then I put that outline on a tool layer and lock it into place on the workspace. Now I have a jig that is setup for repetition work, and an outline on the workspace to fit my design into.
Burn one, open the enclosure remove and replace with new coaster and do it all over again without having to futz with placement.
