Someone near me has an older Delta/Rockwell shaper for sale for a very low price. This is the one with the open base under the table, similar to this Grizzly model, but with a 1/2HP motor. I'm wondering if something like this would be worthwile for a hobbiest for making occasional raised panel doors? I already have a good router table with a 2-1/2HP router, but I'm under the impression that a shaper is much more powerful for a given HP rating and that the slower turning cutters work better. Assuming it is in good mechanical condition, is this a worthwhile tool?
