  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is 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!

    YASMT: Allen Bradley Mag switch wiring for Single Phase

Standard procedure in those days. I like the hardwood wedge on the drive dog too. Thanks for sharing the video - love those old B&W...

    Both the compound lock and the cross-slide lock use a wedge profile (brass) pushing on the gib strip. These profiles are shown in the red and green circled areas in post #9. They are shown outside of their actual location. A) Compound The locking bolt passes through the wedge in a clearance...
