I recently purchased a Stanley #90 rabbet plane. After not getting good results trimming a tenon, I read more online and discovered one (I’m sure there’s more) difference between a rabbet plane and a shoulder plane – the fact that the blade is near the front of the rabbet plane and just forward of center in the shoulder plane.
Am I using the rabbet plane wrong or did I just buy the wrong tool for tenon shoulders?
Also, any recommendations for a good, reasonably priced, shoulder plane? An article on this site recommended the new Veritas model, ranking them both best overall and best value, but I would like to spend less than the $180 plus shipping that Lee Valley sells their medium sized model for.
