Tools: the small Surform rasp was pretty useful. I also used a scraper made from an old saw. At the top is a surform rasp mounted on a bit of minicel foam.
I also resorted to filler on the resultant thin spots, and dealt with the internal stems by filleting the corners.
Glassing didn't go easily. The glass seemed to really want to pucker & lift off the wood. I tried the "saturation coat" that some builders use, but it mainly seemed a waste of epoxy. However, I think I'm finally learning what causes this-too much epoxy and too long a saturation time. The glass wants to float up to the top of a deep coating of epoxy, unevenly, of course.
