Hey guys I have decided to follow in my father and grandfathers footsteps and take up woodworking as a hobby. I just purchased a 187 year old house and have plans on doing some work around here (after plenty of practice). I'm 27 and have basic woodworking skills for the time being (mostly construction carpentry like framing and deck building). I have basic tools (an old Shop Smith, bandsaw, miter saw, oscillating spindle sander, old shaper, small 1/4" router, belt/disc combo sander, and various common hand tools). I inherit all of my fathers old tools as he gets new ones. I have access to all of my fathers tools (planers, lathes, you name it, he has it) but I would prefer to do things on my own. My questions lies with my shaper. I just got it and have been messing around with it. Its an old craftsman 1/2hp, 1/2" shaper. Its in excellent shape, but grossly underpowered and the 1/2" spindle limits what I can do. My dad ( who is a retired machinist as well) has motors laying around so I was thinking about upgrading the motor to maybe 1.5-3hp. I was also thinking about using bushings so I can use 3/4" cutters. Would this work for me? I know I need to keep in mind that its still only a 1/2" spindle so i cant get crazy with the size of the cutters. Thanks in advance.
