Mungo and Will, thanks for your feedback!
childzplay, thank you! I had 2 problems with the dovetailed bolsters. To keep the angles the same I adjusted my disc sander table to the angle I wanted and then ground both bolsters and scales without making any changes to the table (ie, you wouldn't want to do bolsters one day, change your table around for another job, and then try and reset it to the same angle later for your scales.)
The first problem was that my disc was probably a little dull and it runs really fast, so the light wood burned/scorched at the dovetail. I did not think this would show since it's the surface mated to the bolster, but it does to some degree. The second problem was that even though I went to great pains fiddling and checking and fiddling and checking to assure everything was clamped right to drill all my pin holes, once everything was done I had a small gap on one side. I don't know if the scales move during drilling, or if it's just all of the tolerances of all the hole sizes, pin diameters, etc. that once it's all put together things change somewhat. Another maker suggested that I first bond one side, then drill the holes, then bond the other side, and drill those holes, all in separate stages, to prevent this in the future. The burnt wood is more visible on one side than the other, and it is probably the side that had the small gap that makes it easier to see.
