I was just making final fine cuts on the interior of a medium size (Max 9" OD) segmented wooden bowl. The wood is primarily walnut. I was tardy in taking my thickness measurements and all at once was aware of light shining through at some of the joints. This is near the middle of the bowl. Just cut it too thin. Rather than quit, I went through my regular sanding routine without removing too much additional wood and went to my usual finish (Homer Formby's Tung Oil Finish. I normally put on about five coats.
The bowl is quite attractive although much too thing for much use but I was wondering if there is an additional finish I could put on the inside surfaces of the bowl which would not detract too much from the appearance but might add a little additional stability. I already have five coats of the tung oil finish on all surfaces and the bowl is still attached to the face plate. I will need to remove that very carefully. I was thinking of some of the type of epoxy which is used to coat table tops or bars which can easily be put on to a thickness of 1/16" or more. Can anyone suggest such a product and where it might be available and comment on the appropiateness of this approach?
