  • 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!

    Steam engine patterns for casting

    I've seen that guys videos. They sure piqued my curiosity. Sadly there isn't a consumer microwave large enough for me to cast a 1/2 HP steam engine using that method but model steam engines may be within reach. His safety protocols scare the bejeebus out of me. Having said that, like you I'll...

    Gerstner Tool Chests

    Thanks, I like it, you make two of us who like it. In the US I'd send your wood to K&G for thermoset resin stabilizing. However to be clear, torrefaction is a completely different process that chemically alters the wood itself through the mailliard reaction, the hues vary by the length of...

    Tool Vevor Drill Bit Sharpener Improved

    The parts I tried were printed with the default cura infill settings, which isn't that much. But I dont know exactly what because I didn't print them. They were super light so I think 10% and only 2 walls. IF I was printing a final version for actual long term use I'd go with a cubic infill of...

    Steam engine patterns for casting

    This exactly, at least in Toronto. You need to do casting type that you go engage in indoors without attracting attention. or risk the wrath of multiple Karen's before they even had a name for them. Years ago I made moulds, a lot of moulds, for my mom's ceramic doll making and for D&D...

    aw man that is great. That's a nice kits to build and steam. I especially love steam models that include generators, even if they can barely light a tiny incandescent bulb. Enjoy machining those

    Steam engine patterns for casting

    I'll comb thru my archives and bookmarks and put together a few posts for this thread. Jewelry and small engine parts have much in common. Ideally I'd use a an SLA printer with a castable resin and lay out my casting tree in one piece, then investment coat, burn out and cast in aluminum, insert...

    Steam engine patterns for casting

    with the advent of 3d additive printing, specialty filaments and resins, investment casting is the way to go by far. Vacuum casting flasks and machines can be made by any experienced DIYer. Lots of options exist though, waterglass techniques that go way beyond making mould cores, and old...

    Steam engine patterns for casting

    Patterns are easy to create from a drawing, or scaled finished dimensions if you follow certain rules. One is to scale up the part to account for shrinkage based on the metals to be cast, two is to allow sufficient machining allowances, and three is to accommodate draft if using sand casting...
