clamping the glued in rings down

                   There has been a slight delay since my last post, but here I am again, continuing with my tenor guitar soundboard preparation. This is a redwood top, and it has been thicknessed down to about 2.5mm on the 16 inch drum sander.The 4″ soundhole is positioned at the end of the fingerboard. The rings are made up of thin plastic sandwiched together. A dremel tool is used with a soundhole jig attached. A 3mm hole is drilled in the soundboard to take the guide post, and the tool is swivilled around this post, cutting the recess. Careful placement of the cutter is needed to ensure an accurate fit of the rings in the recess. If the recess is wider than the cutting bit, then you will need to adjust the diameter of the cutter each time you go around.Clean out any sawdust from the recess, then fit and glue the rings in place. A wide board is needed to clamp these rings down. Allow to dry for several hours. The rings can be sanded flush under the drum sander once dry. The dremel can be used again to cut out the soundhole.Hand sand away the sharp edges of the soundhole.
