  • 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!

    Brown&Sharp No2 surface grinder any good?

    Hello All, I’ve been on the lookout for an affordable surface grinder for my small garage shop and I can’t really afford (money and space) any of the import ones I could find online. I found a Brown and Sharp No. 2 surface grinder which appears to have a small enough footprint to fit in my...

    CA-ON Source for cast iron in Ontario

    Quick update: I finally called Mr. Steel and they said they never stocked cast iron, it’s just listed on their website. Instead they recommended McMaster. I ended up calling terranova and they said they can do small orders but I need to give them the exact finished dimensions

    Makes sense, probably just a bad assumption on my part.

    CA-ON Source for cast iron in Ontario

    I do have a registered business but as @Rauce said, I was under the impression that outside the US, they validate if the address is a commercial one. I really wish I can order from MC because they have a lot more than stock metals.

    CA-ON Source for cast iron in Ontario

    Hi, Does anyone know where I could get small quantities of Durabar or similar grey cast iron in Ontario? I found the distributor of Durabar in Ontario but their catalogue lists lots of a few hundred pounds of material so I didn’t even bother calling them.

    Motion when locking the axis

    I think the intent behind highlighting the angle change is that this angle change happens relative to the angles of the dovetails which are supposed to be coplanar. The angle of the sides of the gib doesn't actually change as you stated, it only changes relative to one of the two dovetails. So...

    Motion when locking the axis

    Not at all! the different points of views are brining more clarity as how tapered gib geometry interacts with the dovetails in ways I wasn't thinking about before. I'm finding this discussion really useful and a lot of fun! The discussion certainly helps me with a better understanding of the...

    Motion when locking the axis

    This happens because of the compound angle formed between the dovetail angle and the gib's taper angle. Even if the dovetail was square not at 120 included, rotation of a tapered object on a plane results in change of angles projected on a common view plane(if that makes any sense :))

    Motion when locking the axis

    @PeterT thank you for taking the time to explain this and also to make measurements. My initial setup while very crude served to confirm the same: a lifted tapered gib that’s making full contact with one of the dovetails cannot make full contact with the other dovetail. Why does this matter? A...
