I have a harbor freight bauer thickness planer. It is a decent planer. The main problem I have is that it doesn’t have a locking mechanism for the depth. I am trying to plane multiple boards to the same thickness, and without a depth lock it is hard to get the consistency that I want. The only thing I can think of is to plane a small amount from the boards and than set them next to one another and check them with a straight edge to see if they are close enough in thickness. Any additional advice or recommendations?
