When surfacing my spoil board I noticed ripples that can barely be felt by hand. It does not look like the machine is adjustable, so this has me worried. When I take a the spoil board bit and spin it by hand close to the surface of the factory mdf, it leaves a 3/4 circle mark. Clearly the spindle is not perfectly square to the machine but I'm not sure what is acceptable or not.

What can I do about this? Is there some way to tram a camaster stinger 1?
