  • 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!

    2 flute or 4 flute

    If I had to guess, 2 flute EM might be marginally better based on deeper & wider gullets vs 4F from a swarf clearance perspective. More cutting surfaces might help a bit when you get to the interrupted break throughs but maybe not enough to warrant it. Just a gut feel, nothing more. The bigger...

    2 flute or 4 flute

    Ah, I get it now. I thought it was just making a big through hole with a challenging path. Maybe more like a piloted counterbore but probably a longer shank? I doubt these would be long enough in stock form, but maybe some kind of extension could be fabricated as long as it had proper clearance...

    2 flute or 4 flute

    I like these high relief angle EM's for aluminum. I don't let them taste steel. There are some funky new styles now I may have to try just for the heck of it But back to your project, I think an annular cutter would be better. It has proper clearance for plunging deep. Radial teeth vs a...

    Tips/Techniques HH Roberts replacement milling heads

    Has anyone done a retrofit using one of these heads or prior exposure using a machine with one? I'm afraid to ask how much, but it would seem to be a relatively direct bolt-on, 1-stop shopping fix for a junked Bridgeport/clone head and/or to get VFD speed control without a lot of extra...

    Apron repair

    That looks good. 1a) now is the plan to drill & tap the hole for the same bolt middle-ish of the patch piece? If so, maybe the way to approach is glue in the patch, maybe even a smidge proud. Then mill flush if that's the stage when you drill & tap the hole. Because if the patch ends up even a...

    Machine Video of a healthy (?) Kopp variator

    Wow. I think ISO is a defined kinematic viscosity at 40C, so if your operating temperature is much above that, its not too far off the equivalent viscosity of water ( = 1.0 cS)

    Funny dot on Windows 10 user icon

    I have zero Linux experience beyond a few YouTube videos. What do you do when you buy pretty much any current hardware device - printer, keyboard, scanner, mouse, bluetooth device.... Seems like their application software (drivers?) only recognize Win or Mac & that's it? My hardware requests...

    US Tariffs

    I haven't followed what's happening with the likes of PM / Quality Machine Tools (Matt) or Little Machine Shop or any supplier sourcing from problematic parts of Asia, but surely they (and well, prospective customers) must be taking a hit.

    Zenair CH601HD

    Divinycell is one of the common composite sandwich core materials. It comes in sheet form which you can cut or shape or heat form, 3 PCF density so quite light. I've also seen it pre scored with kind of a mesh backing so it can conform to curved surfaces. Last-A-Foam is more of a structural...

    Funny dot on Windows 10 user icon

    Unrelated but this is the red dot I occasionally get in Chrome. For some reason only/predominantly this site. I used to think it somehow was acting like an alert to a subscribed post, but that's not the case. Ask Google & you get a multiple explanations. Back to OneDrive, yes they are...
