  • 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.

    Tips/Techniques Can I bend a chrome Vanadium wrench without heat?

    If the wrench is good metal, it will be _very_ hard to bend and won't move; and then it will snap.

    Flexible metal conduit or cable - Source?

    Look in the plumbing section. There are various lengths and diameters of hoses that are armored, liquid tight and designed to be repeatedly bent and moved around. Unlike most of the flexible electrical conduit which is designed to be bent only once or very occasionally probably you want to...

    Tips/Techniques Urban and traffic planning

    I'm not swearing at the bikers - I'm swearing at those who have installed them. The bikers themselves are legitimate road users, but the bike lanes near my house make it more dangerous for them along with anything else. On Bloor street (one of the ones in the news), the lane is to the right of...

    Tips/Techniques Urban and traffic planning

    I live in Toronto where they add bike lanes to make it less safe for bikers, and more inconvenient for everyone else. And many drivers have trouble with the difference between a red light and a green one; forget about ignoring right of way, passing on the right and being willfully blind to...

    Center drill or spot drill

    Versus the alternatives (do nothing, or a center punch) both seem preferable. I think we can all agree that a spot drill is the best, a center drill used well is very good, a center drill used badly maybe okay, and the other options are much worse. And if you need an actual precision hole...

    Center drill or spot drill

    But the center hole isn't for starting drill bits? The second part of the profile is to make an angled hole that has relief at the center so that a tool (like a center) can then be engaged. To start a hole for a drill bit, only a small portion of the first part of the profile should be used...

    Why no ground wire?

    I have never heard that specific terminology, but it seems about right for the standard wiring in North America. for 3 phase systems, you have the choice of Y or delta wiring. Both could be with or without a ground, but only the Y layout has a neutral. The delta arrangement is almost always...

    Why no ground wire?

    Every 3 phase system carries the largest current in the 'zero current' white neutral wire.

    Why no ground wire?

    For those of us who live in the city, ground wires look like an added layer of safety. But even in the city, if you look carefully at the power poles, you will see that ground and neutral are merged. And then they go nowhere except into the ground

    Tips/Techniques better suggestion for holding thin sheet metal for milling?

    For a one off part, maybe you can cut out the profile you want from a thicker piece of stock, and then saw off the part close to the thickness that you need. Then grind flat and finish.
