Firstly, I apologize if this belongs in a different forum, I just figured engravers use baltic birch
I have been working with baltic birch for a while now, I'm running into warpage problems over time, I lay them flat on top of each other, the area I live in "Alaska" is quite dry most of the time especially winter, it's not drastic warpage, just twists or bows so I need to tape the edges down so everything cuts properly, if anyone knows of a nice trick to keep them flat and straight or an easier way to flatten them out in the engraver please help
Thanks
