One of my projects in the spring will be rebedding my teak handrails. I assume this means removing the teak bungs so I can get at the screw heads beneath. However, I've never done this before. I've heard of "drilling out the bungs", but I'm not sure of the technique involved. Is it simply using a bit the same size as the bung, or is there more too it? FWIW, the underside of the bolts are easily accessible in the cabin. Any advice appreciated.
