  • 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!

    fixing a folding shovel the wrong way (making a hirth joint)

    or do like any sane person and make some sort of cnc router haha Good eye - my mill is a 1955(?) deckel FP1. I got it in 2020 from the estate of a guy who had worked at E. Leitz Canada (now raytheon elcan) for something like 50 years, which is super cool since I use/fix/modify Leica cameras...

    fixing a folding shovel the wrong way (making a hirth joint)

    for what it's worth, I bought both of mine (GVWU + GVW150) for 700$, which I think was a fair ish price. pantograph machines are virtually useless and basically worth scrap, and these are even more niche than pantos... if you wanna buy one the real difficult thing is finding one in Canada. I...

    fixing a folding shovel the wrong way (making a hirth joint)

    basically it turns one of the linear axes of the panto arm into a roll axis, fixed below the engraving spindle. so like transforming X-Y into cylindrical coordinates (X - θ ) if that's any easier to understand. here's a little timelapse video from a couple months ago, maybe seeing it in action...

    fixing a folding shovel the wrong way (making a hirth joint)

    yeah one of the many ironies here is that the shovel is actually worse than it was new because it's even shorter now (= even more back strain) I did sort of make drawings but not real ones - just something messy to know what to machine. engraved with a roll engraving attachment (for engraving...

    fixing a folding shovel the wrong way (making a hirth joint)

    I haven't lived in toronto for long but this past winter was the first time where it snowed enough that I had to actually buy a snow shovel. princess auto had what I needed - something small with a plastic hinge so it could be stowed in a car more easily. Made in canada too - how bad could it...

    Reasonable price for steel plate?

    if I recall a good price for cheese steel plates (like 44w or whatever) is 70 cents / lb? so maybe a bit more for a homegamer quantity (I think hollow structural section was $1/lb not long ago) i forget but if you're in the ottawa area I used to use loucon metals, their pricing was not bad...

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

    well in my case it's because the drivetrain of my lathe has been removed for repair haha. but maybe it's a good way of generating large radii which might be more difficult on a lathe with a ball turner kinda deal OK so I think this is about it: I was gonna re-write it out and whatever but...

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

    ok so had a bit of a think and yell with the bossman at work, farted around in cad a bit and then consulted the sacred text (Tom Lipton's "metalworking: doing it better") and with some formulae and diagrams in front of me things are making more sense. Too bad I couldn't find this online earlier...
