  • 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!

    3D Printing an armature fan for a router

    Reminds me a lot of RC EDF (electric ducted fan) Chances of retrofitting probably slim but just mentioning more for comparison purposes. They look like injected plastic but I'm not too familiar with EDF power & RPM levels. RPM might be comparable or higher. But 3.25hp router is 2400 watts so...

    3D Printing an armature fan for a router

    Hard to say how much engineering is in the router blade design from an air flow perspective. From across the room it generically looks like this article link.

    Tips/Techniques Hand fitting for an interference fit?

    We were just chatting about this, link below. Not to make light of 'glues' but when you look at the specs for Loctite, this is really what they are engineered for. Not sure about the end application but the inner race of a roller bearing is not going to have a lot of torsional stress on the...

    Meehanite Cast Iron Available Locally?

    When I made the cast iron liners for my radial engine I made a lapping tool from aluminum. Partially mimicking a commercial version (pics) & partially a Robin Renzetti video which you should watch. What kind of made TLAR sense to me was a higher slit count & the relief holes quite close to the...

    Import D-Bit Grinder - What did you buy?

    You mentioned Grizzly. I heard they discontinued distributing their D-bit grinder a few years back. I checked again & unless I missed, don't see one. https://www.grizzly.com/search?q=grinder&cp=2
