    Sorry, haven't posted for a while, been able to escape this project and do some other work.
    Have most of the parts built with the exception of the main rod packing gland. Been making scale fasteners to replace the machine screws I used, many more to go.

    Wanted to add a control valve, did a search on the internet and the great goddess google linked me back to here. Blogwitch in answer to another query posted a set of plans for a globe valve. Had to change a few sizes to match my piping but all worked out, THANKS a bunch John

    It looks good but may make one slightly larger. The engine runs nice on 8 psi but with the valve in line I need about 20 psi on the regulator to get enough flow. lol

    I have to say, one of the best things about being a machinist is learning from others. I built a Stuart #1 in 1977, when I was in trade school, and I wrecked the crank,,,tried to make offset clamps to run it between centers per my instructor..and then did it 2 more times from bar stock, before getting it right. What an awesome crank jig!
