  • 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!

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!

    Rock Tumbler

    Come on John! Jig up a rotary axis on your printer and print directly onto the rod. I know you can do it! On the other hand I use compressed air to install grips on my golf clubs. You could use that method with surgical tubing.
