• Scam Alert. Members are reminded to NOT send money to buy anything. Don't buy things remote and have it shipped - go get it yourself, pay in person, and take your equipment with you. Scammers have burned people on this forum. Urgency, secrecy, excuses, selling for friend, newish members, FUD, are RED FLAGS. A video conference call is not adequate assurance.

  • 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!

    Donkey Engine Model

    That's for sure! The "Antic" (in the lead photo) was built in the 70's and first flew with a Heathkit radio. It's had 4 or 5 different radios and at least three different engines in it. The current ones are no where near modern. I'm afraid I'm no longer flying R/C. In my opinion, "drug...

    Donkey Engine Model

    Thanks for all the wonderful comments! The crank handles operate the drum clutch mechanism. Winding the handle clockwise pushes on the angled pushrods near the drum which in turn pushes the slides out towards the drum. The slides have maple dowels that provide the friction against the inside...

    Donkey Engine Model

    Thought I'd share my latest. It's a model donkey engine based on the Wm Harris drawings but at 60%. I wanted it to be small enough to use the 3" vertical boiler kit from PM Research. The engines are 0.6" bore and use Elmer's Engines slide valve design. Perhaps some of our members, especially...

    Time for some fun

    Parents that could comfortably respond, "Don't know where the kids are but they'll be back when they get hungry." Catching the chicken that was going to be lunch. ("Real") Hardware stores with at least one wall covered in drawers full of useful stuff and wooden floors and a pot bellied stove...

    Show us your pups

    We too lost our dog about a year and a half ago. We decided that he was the last. That only lasted about three months ... the house and heart were too empty. Then this guy "showed up" as a pup (Rough Collie/Sheltie). Walks are fun again!

    Best trips

    If the number of visits is an indication ... Cook Islands, New Zealand and Italy. All multiple times and would go back again in a heart beat. Each is special in their own way. All of our travels have been wonderful experiences (not to say without challenges though). I wouldn't change any of...

    Steam Engine build in double scale?

    I've built engines both larger and smaller than the original design. All have worked out fine. One consideration not mentioned so far (likely because it is os obvious) relates to fasteners. You may not be able to find "exact doubles" of the originals - just use what's close watching for...

    Tips/Techniques A (mostly) Successful Investment Casting.

    Very nicely done. You may not think it perfect but it sure looks good from here, especially given that it's been cast and not fabricated/machined.
