Setting up Brown & Sharpe Screw Machines

Professional Setups

What I'm talking about here is a setup for maximum integrity.  For those of you that have walked into someone else's sloppy work and finding yourself scrapping their setup up because the parts are varying all over the place, you know where I'm coming from.  I've seen guys put drills into oversized bushings and squeezed them so tight the drill is leaning at a 15 deg. angle out of the turret.  Combine that with boxtools and floating holders extending within the last .020 of the turret clamp for extra measure of unpredictability.  It's anybody's guess what keeps the tools from flying out of the turret.  Then, after the 'masterpiece' is finished, I've seen the setup guy beam with pride, brag about his swiftness, and inform his operator to take over the job.  You see, according to the setup guy, if he can manage get 5 parts in a row off the machine barely in tolerance, the the problem is no longer his.  It's the operators!  What the operator ends up with is basically a headache.  The drills need correct bushings.  The turret needs to be adjusted forward at least an inch, and all the tooling must be readjusted to compensate for the turret movement.  Of course, while the poor operator is coming to grips with the mess while attending his other machines, the setup guy is giving himself a reward, a pat on the back by reading the newspaper.  About an hour later when supervision wants to know what is wrong with the job because the customer is screaming for parts, the setup guy remarks something like, "I don't know. It was running fine with I turned it over to him," implying the operator screwed up his job. This is a great way to develop major frustration that would go to blows in fantasy.  The point here, "if it's worth doing, it's worth doing right the first time."
