  • 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!

    Giant metal boulder sculpture (art casting with sand molds)

    I'm just glad I'm not the one in charge of welding it up! The difference in alloy between the cast A356 and the tig wire and the extruded plate sections is a concern, hopefully he'll be able to mask any obvious colour changes with patination and other surface treatments. He has started...

    Giant metal boulder sculpture (art casting with sand molds)

    That's awesome, I would have loved to see that. The big furnace above came from an art foundry near Niagara Falls, where Bill Jurgenson cast silicon bronze sculpture for a number of artists for 4 decades as well. Including some very large pieces. Although he specialized in lost wax casting...

    Giant metal boulder sculpture (art casting with sand molds)

    That's an A25. Biggest one I've ever used. My 12x16 casting shed is too small to run my really big furnace that takes an A70, where would so many (or such big) molds go? A6 for scale But I've got the gear.to.handle it (with a gantry crane) once I finally save up enough to build a bigger...

    Giant metal boulder sculpture (art casting with sand molds)

    Looks great! Interesting technique too. 3D printing has definitely been a useful tool for me here as well. Every one of these were cast using 3D printed patterns. Most are cope and drag flask sides... Well not these shoebox lid accents Casting class toolkits This was the last of those...

    Casting aluminum

    I'm curious what it looks like too. Also wasn't sure if "in the works" meant yes he has found a foundry or yes he has a pattern ready. :) Jeff

    Giant metal boulder sculpture (art casting with sand molds)

    Not easily! :) It's different than anything else I've worked on, that's for sure... My first time using 2-man crucible tools, that's been fun. Jeff

    Casting aluminum

    This sorted yet? If not, I'm wondering if you have got a foundry pattern prepared. I'm way out in Ontario, definitely not near Calgary as requested, but whoever ends up with this job will need to know. I checked the member map we have on another forum where I mod (thehomefoundry.org), but...

    Giant metal boulder sculpture (art casting with sand molds)

    From day 1: Day 2: Tried this one twice but the long arched piece kept slipping out of place and ruining the mold whenever we went to open it up. :( Out of these 2 patterns we wound up just getting the smaller of the 2 poured (the mate to day 1's casting) in its own mold that day Here's...

    Giant metal boulder sculpture (art casting with sand molds)

    Been working with local artist David Perrett on his latest sculpture, specifically I'm helping him out with a lot of the foundry work involved. He's got his own foundry newly set up after moving to the national capital region from Hamilton about a year ago, so I've been driving out to his place...

    Tips/Techniques Making file handles

    The corebox would be the fun part! I'd have wanted to cast them in one piece and cored too. Probably would have been the very reason why I picked that particular handle to try and copy. Anyhow, Seth's presentation and results always look really great. Everdur is expensive, but such a joy to...
