  • 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!

    Calgary & area meet up Spring 2024.

    I am interested, can’t promise - what with being retired (now busier than ever ). I could present how to make jaws for a scroll chuck (i.e. typical 3J chuck with one piece jaws, when it gets to the auction house the second set of jaws is long gone). Like so many others, when it happened to me...

    Do you have a mill and what kind is it?

    Maho MH600 is one of the little European multimills, with most of the available attachments (and a second one in case I ever need a replacement part, so far it is just parked in the corner) Cincinnati 1D Toolmaster Huron KU3 with the all angle head Bridgeport VMC1000/22 4 axis

    Tool Morse taper drill bits

    There is lots of new drilling technology available now. +1 on the annular cutters. I have used spade bits a few times, easier to turn and much less chip tangle. I rarely use MT drills (and I have quite a few).

    Ball Bearing Collet Nuts

    Yes on the ball bearing collet nuts. The TG100s that came with the machine (about 10) all have the bearing nut (3 styles of holders), I’ve since purchased some ER (to get in closer). I’m using the std nut in ER20 (pretty small) but the ball bearing nut in the ER25 and ER32 - my main reason is...

    lathe compound pedestal thoughts

    What is the purpose of replacing the compound with a pedestal? Is there a problem with the function of thee compound? I have a similar size (15” swing) lathe, not a very heavyweight version, but works great. Parting off works fine, etc. Just for fun, I bought a rear tool post (which is a...

    Tips/Techniques Finding out 3ph motor voltage without a nameplate?

    What is your guess on the horse power? A rough rule of thumb is: 575V - 1 HP per amp. In 240V you need btw 3.5 to 4.5 amps per HP (depending on slip, fan size, the design voltage 208/220/230/240 etc). Could be just those two (or 4) screws on the square cover over the coil. The control looks...

    Tips/Techniques Finding out 3ph motor voltage without a nameplate?

    Is there a control transformer (i.e. check what taps the the high voltage side of the control transformer are wired)? It is very unlikely that the coil on the contactor would be at line voltage. I find that most machines use 120V (or 24V) for the control voltage - certainly not 575V. If there...

    Milling machines, what to buy/look for

    Providing 3 phase 575 is not difficult. If you can bide your time, it is not even very expensive. As usual, it depends on your situation and what your plans are. Start with sorting out the 3 phase. If you have (planning to have) a few industrial type machines (meaning 3 phase machines and...

    Quality countersink(s)

    I’m really liking the 3 flute design (sourcing from MSI in Edmonton, made in Germany). Yes, expensive, work great. Available in the usual angles and various sizes.

    Threading - 29.5/30 vs 90

    Being a little contrarian, I’m for 27 degrees on the compound (cut advance on the compound, in/out retract on the cross slide). The rationale of 29 or 29.5 degrees is still relevant (puts the chip on the one side, curls off nice and leaves a good surface finish) - I believe the exact value...
