  • 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!

    Mazda 6 doesn't like Canadian winters

    Everything has been covered pretty well here, but @PeterT had a question about resistance tests. They are a valid test, but only when they have too much. Say you test from center of battery negative to engine block, or some other normally grounded point, and your meter reads 5 ohms. That fails...

    Mazda 6 doesn't like Canadian winters

    That's a good general overview, however, he's in a warm shop and that engine is cranking like crazy. So his values are different than what you'd see in a cold climate, no crank situation. His statement about different allowable values for the positive and negative side is incorrect in my...

    Mazda 6 doesn't like Canadian winters

    The underhood chargers do have their place, and i've recommended and installed a lot of them. They are good for vehicles that are used infrequently. All newer cars have some amount of draw. 30ish mA is usually acceptable, but on a volvo, I have seen 10x that be considered acceptable. Those cars...

    Mazda 6 doesn't like Canadian winters

    There's dozens of vids and stuff on voltage drop testing, and are worth watching. On you dvom, set to 20v scale, one lead on center of the battery post, other one the engine block at a clean location. Have an assistant crank it, I like to see less than 1v on the meter. If more, attach a...

    Mazda 6 doesn't like Canadian winters

    A voltage drop test during cold crank on both the ground side and the positive side is quick and easy to do and will definitively prove out where the problem is. A new fully charged battery or an onboard charger will mask the problem , until it doesn't. I see issues exactly like this in my...

    Mazda 6 doesn't like Canadian winters

    Sounds like a no crank/no start ? If so, voltage drop test all grounds during cold crank, use thermal imager for hot ground points. If I recall, there's a trans to body ground under the battery tray thats problematic. If the ground is bad you'll get poor cranking as well as reduced current...

    Is a shaper the only machine that can cut a key way?

    A file will do it too. Make a plug, mill a slot in it , like a broach guide, but use it as a file guide. Done in 10 mins and good enough for a motor. If you have a mill, you can mill the keyway. It doesn't have to be square in most cases. Or partially mill it and square it up with a file.

    dumb question about deep sockets

    I am a mechanic. I prefer the Snap On 99% of the time, but it all depends on what you are doing. I have both to choose from now that I work from home, and use both depending on which side of the shop I'm working in.

    How's this for accurate machining?

    Although very impressive, I have questions. Is it repeatable, or is this a one time thing for a show? Can this be done the first time every time? etc.
