My question, I have a large table top glue up (42" wide) that has been sitting in my garage for several years. I am thinking about finishing it. A friend has a Jet 22-44 drum sander and said I could bring the top to him to flatten. Will a drum sander work if the bottom of the panel is uneven (the top is fairly even)? Or will it be sort of like a planer and transfer the uneveness to the top of the panel?
Thanks
Scott
