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!

That's pretty cool.
I did my apprenticeship at a plastic injection mold shop. We had a huge Hyd-Mech bandsaw that could cut to something like 30" stock. We used it for cutting solid blocks of P20. Blades were something like 2-3 teeth/inch. Slow speed, slow feed.
Every now and again someone would toss some angle or tubing on it and mangle the blade all to hell lol.

30" stock? I guess molds can be pretty big.
P20?
P20 metal is a type of tool steel commonly used in the manufacturing of plastic injection moulds and die-casting dies. It is a pre-hardened steel, meaning it has been hardened to a certain level and can be machined without additional heat treatment. P20 typically has a hardness of around 28-32 HRC (Rockwell Hardness) and offers good machinability, toughness, and polishability. It often contains chromium, molybdenum, and nickel, enhancing its strength and resistance to wear and corrosion. -so says ChatGPT

Yup, that's the stuff. Slow days some tooling would be made with the drops. 123 blocks, parallels, sine bars etc. Can be case hardened, at least I was told as much.
Some of the molds we did were for dashboards and door panels. Huge molds. Those blocks would come pre cut. The saw was for the smaller components, slides etc.
I miss that shop. Long closed. Bosses were fantastic.
