    Help chatter while machining a shaft (CNC lathe).

    Use a positive rake insert- - back in the old days, a common shaft turning insert was a KNUX, lots of side rake to curl a chip, but great for reducing chatter. The ones we used were Sandvik. Looks like they are still available...

    Brass bushing ID reaming/boring

    Either make a piloted reamer and put a guide bushing in the 1st hole and then ream from both ends or hone them to size- I would hone them if I had the choice. A few swipes on a Sunnen hone and they would be in alignment and on size.

    Berco Cam Grinder Runout Issues

    Cam grinding is as much an art as well as a skill. The difference between a great cam grind, an ok cam grind and an absolute junk grind is dependent on a good machine, accurate masters, the care, knowledge and skill of the operator. Agreed, grinding in general can take years to master all the...

    Reversing Contactors Wiring Diagram

    Because if one set of contacts hangs up mechanically, you have a condition where you have a dead short across the contactor. Electrical interlocks may prevent a coil from energizing but nothing in a contactor senses a hung up contact unless that's a new feature I'm unaware of. When that happens...

    Hopefully you are aware that camshafts do distort during grinding and require straightening ...........sounds like you are really struggling- best to you- keep trying cuz it does not sound like your coworkers are very helpfull. You must have great shop owners to allow that to go on.
