Scammers have burned people on this forum. Urgency, secrecy, excuses, selling for friend, newish members, FUD, are RED FLAGS. A video conference call is not adequate assurance.

  • 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.

    I use a deburring tool and a small block plane to chamfer the edges. The soldering iron works ok if you have a fine touch, though I found I was just a twitch away from ruining a nice print. The hand plane is much nicer! I always use an internal fillet or chamfer in boxes, and on the...

    I bought these a few years ago from Model Engineering Supply in the UK. Not cheap, but very good quality, producing tight threads.

    And on a similar note - Fusion360 has a team environment for project sharing and collaboration. STL, STEP, 3MF, F3D, can all be shared. It might take some thinking about how to set it up as a resource for trusted members, but I think having a CHMW Team might be a valuable asset for the...

    Will this switch work?

    How much power is involved? What happens when you flip the switch into reverse when its running forwards? I would look at a contactor instead of a switch if theres any significant current involved.
