Hey! I'm not just some old fat slob. I'm an old power lifter, I've been lifting wights since '56. Think of a 5'10 250lb long armed line backer who rung a lot of bells, who squats 600 lbs and benches 320. I'm just an old jock, high school football coach still pushin weights with the kids. My nearest neighbor down the road is a machinist with all the tools in his garage. I'll talk to him about cuttin splines in the shaft. Thanks Redcoat
