  • 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!

    How Not to Produce a Simple Wood Pattern

    Nice work on the pattern! There's a foundry guy from Sarnia who used to post now and then on a couple of foundry forums as Foundry Joe and Joe C... I wonder if they know each other. Patternmaking-related, (I may have mentioned this elsewhere) Joe's wife runs Village Impressions, a rubber...

    Giant metal boulder sculpture (art casting with sand molds)

    And off it goes to the Oeno gallery in Prince Edward County... With 2 of us and David's gantry crane and genie lift, getting the heavy base, cap assembly, and stone blocks loaded into his van yesterday after work was pretty easy I hope to be able to make it to the gallery for the unveiling...

    Giant metal boulder sculpture (art casting with sand molds)

    I'd love to cast more functional parts. Started my casting hobby in 2013 with Dave Gingery's 'build your own metal shop from scap' book series, but loved making molds so much when I got done with book 1 (the charcoal furnace book), instead of starting book 2 (build the cast aluminum lathe) I...

    Giant metal boulder sculpture (art casting with sand molds)

    Back at David's place yesterday to wrap up the assembly of his sculpture. Previous pic was dry fit only. It's hard to believe we started casting the parts for this over a year ago! Here is is from several angles, before the top row cap assembly was glued up and put in place. Each stone...

    Anyone using natural gas for their forge

    I haven't tried natural gas for foundry. Only know of a couple people who have... But did someone say waste oil burner??? I do use gravity fed drip injection type waste oil burners in my furnaces. Mine are loosely based on Lionel Oliver's Brute and Hot Shot burner designs...

    CA-ON Bentone 34 or other “organophilic” clay?

    That's great! Congrats. Cool muller. I was.sure I was already subscribed to your YT, but I had to go search for your recent videos and discovered I somehow wasn't, or YouTube forgot I was or something, go figure. Fixed that, anyway. I've talked to a couple people who've used tumbling ball...

    CA-ON Bentone 34 or other “organophilic” clay?

    That's awesome to hear! Looking forward to hearing how the molds and castings turn out. You've done your homework, obviously. For anyone else, or if you missed it, here's a bunch more info on K-bond sand, including Tom Cobett's suggestions (and recantations, regarding the use of glycerin). One...

    CA-ON Bentone 34 or other “organophilic” clay?

    If it's not too late, try to get the fully synthetic smokeless 2 cycle oil for your tests, based on recommendations from Tom Cobett. Its main ingredient is supposed to be the elusive Indopol whatever it's called, the truly smokeless oil used by his class at Kent state that invented K-bond, but...
