I turned a 12" Walnut platter today about 1/8" thick. I'm not sure how this happened (maybe something to do with the wobble in my lathe) but there is a spot just outside the edge of the tenon about 1/4" wide and 2" long that is paper thin and I sanded right thru the bottom of the platter. The thin spot does not go all around the platter, just the 2" wide spot. The actual hole is rectangular - about 1/4" x 3/4". I'm trying to come up with an idea of how to salvage the platter, I hate to think I wasted all day making a piece of firewood. I've thought about cutting a round plug and gluing it in but didn't think that would work well, given the thinness of the wood and probably wouldn't look too good either. I don't see how the hole could be filled with anything either. I'm thinking I would probably have to glue something over the hole. Other than the hole it's a pretty nice platter so I'd really like to save it from the scrap pile if possible. any ideas?
