Slowly getting somewhere. Dremelled out a half-inch using the "flapper wheel" attachment for my dremel, which worked beautifully, even against the epoxy. https://www.homedepot.com/p/Dremel-...r-Wood-Rubber-Plastic-and-Metal-503/100165927
Packed it in with peanut buttery colloidal silica epoxy and used a scraper to smooth it out. Drilled and filled the old cruddy screwholes. Put another layer of epoxy on the forward hole to raise it a bit and smooth it out some... this will get sanded and glassed over next work-day.
Last big steps are to stop noodling about what to mount the chimney on and make something to mount the chimney on. I'm leaning towards a bottom layer of Star Board in hopes that it is less prone to splitting and cracking than a teak block, but then maybe covering the top of the Star Board with a layer of teak, or something. Might look nice...er than just the Star Board itself.
