  • 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.

    Fuse replacement -- CX-706

    @Susquatch - Don't worry, I tend to be quite conservative regarding electrical issues. From my reading, it seems that the motor control board tends to be a weak point in the system. As in the magic smoke sometimes leaks. If that were to happen, I would consider a changing to a 3-phase motor...

    Fuse replacement -- CX-706

    Thanks for the explanation of PWM. I guess another factor, though, is efficiency. AIUI, for fractional horsepower motors, 3 phase motors are inherently more efficient than single phase. Is there any rule of thumb comparing comparing the efficiency of PWM DC motors to AC motors? Is PWM DC...

    Fuse replacement -- CX-706

    I guess the other thing is that I don't really know the details of the motor in CX-706. I would have to disassemble a bunch of stuff to get a look at it. My understanding is that it is a "1 HP" DC motor, aka 750 watts. (Brushed? Brushless?) I've learned a bit about AC motors but my most...

    Fuse replacement -- CX-706

    With the replacement fuse, I went back to roughing down the diameter of the part I was working on. I increased to 0.060" per pass and doubled the feed rate while roughing. To my ears, the machine was not working that hard and I think I could have pushed it a lot further. No fuses blown. I'm...

    Fuse replacement -- CX-706

    Hi: I just blew one of the two fuses in my Craftex CX-706 lathe (10X22). The lathe came with a couple of spare fuses so I'm up and running for the moment but now I want to buy more spares to have on hand. If you assume I know almost nothing about fuses, you'll be very close! ;) First, this...

    Must Be Loco

    Great work, the con-rods look absolutely authentic. Seems to run just fine and considering the age and condition when you got it, that probably qualifies as a minor miracle! When you say you 'reworked the valves', do you mean that you just had to adjust the timing or were there more problems...

    Silly little question

    See: https://www.gitsmfg.com/product/style-gb-ball-valve-oiler/ AIUI, you want a pump-style oil can with a nozzle that tapers to just slightly smaller than the diameter of the opening. Press down on the ball to create a seal and then pump in the oil. The pressure of the oil will push the...

    Lathe carriage handwheel

    ^^ This. ^^ On my CX706, the handwheel is solid aluminum. If it is "literally smashed off", I think that it is pretty much certain that other parts are also damaged. BusyBee does not stock replacement parts for sale. For warranty replacements, I believe they cannibalize a machine. Craig
