  • 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!

    Er40 collet chuck

    I suggest you make a d-bit to do the finish sizing rather than buy a 16 degree reamer. It will involve 3 to five hours to make, harden and hone/polish but it will be good practice.

    Disk finishing aluminum

    I really like all four of my M12 tools. Light in the hand but still enough power to do what I need done. I have the right angle grinder, straight grinder, drill and driver. I also have the Proxxon ac110 variable speed long neck right angle grinder which I use regularly too.
