  • 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!

    Lathe worm gear repair

    I'm not quite clear. The existing key is full span within worm part 57? And the bushings 55 have set screws that engage OD of 57? If this is the case & If I understand your idea - using set screws to act as (replace) the key is not a good approach IMO. All the torque applied to the small cross...

    Ball & Socket

    Here you go. usually I print from .STEP but assume .STL is good enough? I'll probably be modifying this for purpose, but will give you something to fidget with in the mean time

    Ball & Socket

    Just messing around. I have some forthcoming articulating arm projects coming up so made a tester. The ball is 20mm diameter. Stem is 10mm OD to fit a CF tube ID. The lugs hold M4 screws which grip the ball amazingly well, maybe the 3DP striations help a bit. I probably will increase the infill...

    Looking for milling machine purchase help/advice

    I had a Taiwan RF-45 style before my (also Taiwan) Bridgeport clone. It was actually a decent machine. I think they are only getting better +/- the usual caveats. Amazingly the headroom on an RF-45 is about the same. IMO a dovetail model is a better way to go over a post. The comments are...

    Mitutoyo indicator stand 7019B operation.

    You got it disassembled obviously. Were the hydraulic pistons difficult to remove because of aging O-rings, or just needed a magic touch to get them out? Years ago I had a bad Chinese clone attempt at one of these. It leaked & went limp just sitting on the shelf for a couple months. I installed...

    Spade connector question

    Its just one of many causation rumors :cool:

    Spade connector question

    Not sure if you are replying to me but these particular ones are most definitely heat shrink. That aspect is actually remarkably good. The material is 3x the thickness of regular heat shrink tubing & have an adhesive that gets activated like you typically see on tougher duty heat shrink. But...

    Spade connector question

    I see. But if the male also has shrink, wouldn't they become permanently fused once heat shrunk? Or maybe these are not really intended to be plugged & unplugged which I assumed was the whole point? (Its low power application so no worries there).

    Lost foam aluminium casting issues

    FYI - I bought a set of graduated diameter ball ended tools off Amazon for making fillets & similar. I was using a piece of brass tube CA-glued to a bearing ball, but $10 for a 10-piece set why bother.

    Spade connector question

    I bought a handy dandy crimp kit with various terminals. The heat shrink seems quite good, reasonably thick, has a adhesive that activates when shrunk. Supposedly weather proof or whatever the advertisement said. And I'm happy with the crimp aspect. Mostly I've been using ring terminals but I...
