I know this is (very) late in the game to most people... but I have my 11 piece decorative bit set I got with the original purchase of my B machine. And I need to remove the adaptors to use the 60 degree (and maybe 90 degree) v groove bits with some centerline text.

I tried using a T-10 (I think) bit in a screwdriver to unscrew one or both of the side set screws. They weren't budging. I came here and did some searches, and reminded myself of the solution to bake them for a bit, then try again. I first tried 10 minutes at 400 degrees. Not any help. I then tried 15 minutes at 425 degrees. Again, they were still locked tight.

Are there any other things I can try to help remove these screws? Hard to find any advice since all the chatter about it is so old now.
