  • 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!

    Dabblings

    My personal opinion is that if the message from the government wasn't of the form 'thou shalt get this shot or else', but was of the form 'we have a limited supply, please get in line', a huge mess could have been avoided. That kind of absolute message can only make things worse - especially...

    T-Slot Size vs Clamp Size?

    The hazard of bottomed bolts is probably a load applied by that bolt between the bottom of the T slot and the underside of the slot based on the useless screw pressure? Useless because there is no overburden (useful clamping) on exactly that spot on the bed. The overburden (useful clamping)...

    Tips/Techniques using emery on a lathe

    I haven't tried them for this purpose, but I can say that they don't work for the advertised one. I'm sure they would, but that doesn't help when the dog goes a foot off to the side

    DavidR8's shop shenanigans

    That's a picture of a power injector. Power injectors are used when the Ethernet Switch (which could be built into a router etc.) does not provide native PoE on its ports. The pins used to provide power vary based on the supported speed. On standard RJ45 copper cabling, at lower speed...

    DavidR8's shop shenanigans

    One of the few advantages of living in the city (Toronto). Of course this is what I use for my actual job, so it isn't exactly a luxury - the company pays for it, so when they need to wake me at any hour of the day or night, I will have a high quality connection and can fix whatever system...

    DavidR8's shop shenanigans

    It should be noted that modern WiFi isn't very much like classic FM signals. AM signals are the most basic and the information is carried by changes in the amplitude on a single carrier frequency FM signals are more complex and the information is carried by changes in the frequency within a...

    Is Taper Attachment worth it?

    Do you have a good idea of the cause of the score? For me, it's hard to tell from the picture

    How to make motor shaft longer?

    If the motor turns in only one direction, then self-tightening threads + lock tight or a pin or some combination ought to work great (mill power feeds should not run in high vibration environments). If the motor has to turn in both directions, the threads can't be self-tightening because one of...

    How to make motor shaft longer?

    The only thing I would look at is if there is any extra play involved. Even a small amount will throw off the dial on your feed. And since pins tend to be weak (versus keys) this may be fine on day 1, but get worse over time. Since the motor will turn only one way, this is a much smaller...

    How to make motor shaft longer?

    Horizontal power feed. That tells me that the motor will turn both ways, and that the connection needs to be slip critical. That probably eliminates using the existing threads or any kind of press fit connection. You really need a key way of some kind. Does the shaft only need to get longer...
