  • 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!

    Ultra thin tool makers foil

    Hi All, Ultra thin toolmakers foil only 0.0003" thick. It is so thin, I can't even get a piece off of the coil without it tearing and wrinkling. Any ideas?

    Machining a Curved Tee Nut - An Interesting Setup

    Hi All, Setting the radius of the curve was from the center of the rotary table to the center of the round tee slot in the vise base = 70 mm utilizing the previously made pointed round pieces. Since I don't have digital it was literally point to point as seen in photo 692. The outer and inner...

    Machining a Curved Tee Nut - An Interesting Setup

    Hi All, Time to do something I had ignored for decades. This involved machining a new curved tee nut to fit into the round tee slot in the swivel base of my most used milling machine vise. It is not too often that I need this swivel base but recently I did. I had employed the bodge of an...

    Garbage Steel

    Hi All, Yes, I know that HR steel will have some residual internal stress but not that of CR steel. And no, the bars were not bent as the photo shown of these bars was after rough milling and then finish grinding both sides of the bars dead flat on a surface grinder. I also had an observation...

    Garbage Steel

    Hi All, I can't see how it would be bent as the thickness mike's the same all along the length of each strip and even if I machined out the bend, it wouldn't show as a bell mouth as it does . This is typical internal stress redistribution starting from perhaps a too rapid cooling of the metal...

    Garbage Steel

    HI All, This is what we are dealing with these days. There is over 1/4" of warpage at the free ends of these two hot rolled steel strips which are 8" long x 3/16" thick x 1/2" wide nominal. This is after rough and finish machining both sides of the strip (to 5/32" finished thickness). It is...

    Another Bandsaw Work Around - Holding Small Metal Pieces

    Hi All, Another work around dodge. Cutting small pieces of metal and holding them securely while cutting them in the 14" metal bandsaw here which it was never designed to do. Small metal pieces are very difficult to hold securely when cutting them as the bandsaw blade will grab, snap, twist...
