Step 1: Cut Along the Lines
Now let's see how to make it! Glue the printable template onto the plywood and cut along the lines.
Run the piece through the drill press drum to sand the curved shapes, and round the edges with the router.
Step 2: Mechanize
Next, we drill a through hole with a 4mm drill bit and countersink.
Now, we do a channel with the exact thickness of the two washers and the blade width.
We cut and glue two pieces to make the handle more ergonomic.
Sand the handle as well as the Coping Saw. We Will apply varnish later. The final step is to assemble all the pieces, align both washers and put the screws in with wing nuts.
Let's put our blade applying a little pressure to ensure the blade is tight. First we will try it on a piece of wood with a big tooth blade, and now we try it on a piece of acrylic with the thinnest blade I have.
