  • 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!

    Hi All, The valve inner assemblies (consisting of the the valve arm, the valve and the backing spring) are now complete. The last parts involved some interesting machining. The valve backing springs are specified to be 5/32" OD and only 5/64" long! There is no chance of being able to...

    The Equivalent North American Meaning of a Bare Fit

    Hi All, LBSC in the construction article on the boiler blowdown valves I am making uses the term "a bare fit" several times in the text. Does this mean a close fit or...? Is this an English/Scottish term for all of you having a UK background?

    It Looks So Easy and Straightforward ON Paper But...

    Hi All, Finishing a valve by contouring the outer (peanut) shape. LBSC says to do this by filing but I couldn't do it this way if my life depended upon it! Precision filing is a lost art for me and even using a die filer, I couldn't do it this way either as the part, at this stage, is so small...

    Hi All, The valve flat bottom drilling and depth check. Do not try and drill directly with the flat bottom drill as a drill ground this way will jump all over the place. A flat bottom drill is just used to produce a flat surface on the end of a drilled hole. So, the sequence of operations...

    It Looks So Easy and Straightforward ON Paper But...

    Hi All, The machining of the valve. I knew this part, though it looked so simple on paper, was going to present me with a lot of machining difficulties. It had two internal features, a 7/64" through square hole and a flat bottom circular hole. The flat bottom hole I can deal with as, in the...

    Meehanite Cast Iron Available Locally?

    Hi Peter, In the case of the Howler 15, the liner is specified as unplated "Leadloy" steel. My take on Leadloy is it was a good choice for cylinder liners where oil was always present but it is a terrible choice for any other use as you can almost hear it rust. If you leave a clean piece of...

    Meehanite Cast Iron Available Locally?

    Hi All, A very interesting discussion so far - keep it going. Well, I am not exactly up the proverbially sh-ts creek without a paddle as I do have one last piece of GA-50 Meehanite. It was given to me decades ago by Harry Hawkins, a past President of TSME. I don't know where he got it from but...
