  • 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!

    I'm still digging for good info about these spindles. Any recommendations for low speed options?

    High speed CNC router spindle question

    I would like to use an air-cooled high speed spindle (2.2Kw) controlled by a 220V single phase VFD for a precision CNC grinder. The spindles typically run up to 24,000 RPM, but for a grinding application that will need to be much less. The maximum wheel size I will be using is 4" so the...

    Machine enamels?

    I spent some time looking at the SDS for the Endura 2K 2 part paint. It is pretty nasty stuff, so I take that caution seriously.

    Is anyone else using AI to support engineering design work?

    I disagree. Part of that conversation was a discussion about roof and wall R values and how that could be achieved. I was impressed by the response which was much deeper and more inclusive and insightful than a simple Google search would have produced. It included the aluminum sheathing and...

    Is anyone else using AI to support engineering design work?

    It certainly does that. It can also help with the mundane when fully instructed. Take C++ coding for example. When correctly prompted, the code that is generated is really quite reliable and always syntactically correct. Errors occur, but in my experience those are the result of loose...

    thats probably a good option for all machine finishing. I'll take a look at that and the Cloverdale Paint epoxy. Good suggestions folks! Much appreciated.

    Machine enamels?

    I blue some parts which adds a nice colour and some light corrosion protection, but blueing does not add any thickness to the surface, so every scratch is visible and it rubs off over time too. But as I understand it Japanning is a lacquer based finish. I wonder if it is durable enough for use...

    Machine enamels?

    I Powder coat would be good in many situations. The issue there is that the oven destroys the Bondo ! and its an expensive job whether outsourced or purchasing the powder coat kit. I almost pulled the trigger on one before hearing about the Bondo problem.
