I have a 13.5 chuck, so it is relevant to my practice. - so I could use a short cheater, but I prolly won't. I have a concern that too many people clamp too hard on things.

Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

I agree. People should put an indicator on things, and calibrate their Umph sometimes. It would probably be hard to visualize on a lathe chuck, but pretty easy to see how much deflection you can put into something with a mill vise (which should translate). I did that with the last young guy I trained. He was a big strong kid, and his stuff was always "out" just a little. We were trying to figure it out, until I watched him snug something up one day in the vise, and the lightbulb came on, and the indicators came out. We re calibrated him, and all started working out........Screws can impart a tremendous force, which can work against you when trying to machine things precisely.
If you zero out on the fixed jaw, then clamp your part in like you're in an arm wrestling competition that reference plane is no longer @ zero.....
