  • 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!

    Canaweld make (design & assemble) their welders in Ontario https://canaweld.com/about-us/ I bought the 201 Pulse-D back in 2021 and have been happy with it. Cost more than a made in China welder, but can't fault it, its been great, used it for TIG and some stick work. Its also 240/120...

    Hello and welding question

    Welcome. My 2 cents as a hobby guy and no professional experience. You want to weld steel, stainless and aluminum. That to me screams TIG. It does require practice, but will do all of those metals.

    Weiss VM32 CNC Conversion

    They could, but as suppliers of equipment designed for this application I'd trust them to have installed them that way on purpose. No point messing with a quality part, and perhaps they are getting bearings that are matched for face to face preload only. The SKF document I linked mentioned...

    Side note, I actually, just noticed that the BK and FK are face to face mounting for the bearings from Hiwin.

    Weiss VM32 CNC Conversion

    Don't spend money on a matched set until you have a plan for mounting them, your current setup won't make any use of a matched set. I see a few ways forward. 1. Do your best to determine the space between the 2 bearings and make a spacer bush to fit, minus a tiny amount for preload. Give...

    Weiss VM32 CNC Conversion

    They can be either back to back or face to face for bi-directional force which is what they will see in this application. This link has more than you ever wanted (or needed) to know about the bearing arrangements: SKF Bearing Preload That said, with the ballscrew being a relatively long and...

    Weiss VM32 CNC Conversion

    So are the bearings in 2 pockets with a step between them? If so there needs to be a spacer bush on the shaft for the inner races to keep them from being overloaded. Its not the best arrangement, as the tolerances are usually really tight, hence the reason angular contact bearings are sold as...

    Interesting multi axis printer design

    The slicer is the real innovation here, the hardware is relatively trivial. The real trick would be a slicer that can do muti axis, and can handle different multi axis type machines (i.e fixed bed, fully articulated head, even something like a 6DOF robot)

    making "spherical" surfaces with a boring head (?)

    Note that the cutter needs to pass under the overhang created by the part being held at 45°. So In essence a fly cutter arrangement or the boring bar being held in a horizontal plane.
