    Clarkson Vertical Steam Engine 1” bore

    The boiler is almost complete. I redesigned the connecting rod since the video to get rid of the clunk. I will redo the studs so they look neater. Steam will point out any leaks.

    3” boiler project.

    Need to do some clean up and polishing. The viewport is threaded and will,screw into the boiler to light and monitor the flame. I need to add a latch.

    3” boiler project.

    This will certainty do the job. After test running the boiler, I can appreciate the idea of not burning my fingers with the added benefit of heat conservation. I’ve seen several examples of people planking their boilers, but this is the first time I’ve seen it done with efficiency as a primary...

    Thanks! I will give this a try.

    Collet swedging tool.

    I built a swedging tool for use in restoring vintage musical instruments. It works well, but I collets do not stand up to constant use. I was thinking about case hardening. I found a product called “Cherry Red” that I think might work. Typically I am working with brass or silver. I often...

    3” boiler project.

    I am looking forward to running the boiler once I finish the viewport. The burner was certainly one of the more interesting parts of the project. There are some really frightening videos of homemade burners so I thought I’d better get some advice. I meant to ask you what you what adhesive you...

    3” boiler project.

    Burner is ready to go. I’m constructing a viewport with a glass window for the boiler to light and monitor the flame. The boiler just slips on and off. I am thinking about building a coal burning version. Thanks for all the help! I’ll post the complete steam unit after I install the viewport.

    Toolpost Grinders

    That’s the machine. Once I got it setup, it worked fine. Thanks for the PDF.

    Trying to identify an engine.

    It had been next to the parents fire place since 1968. I cut a new crankshaft for it and ran it at an engine show several years ago. The carburetor, tank, strange piping, and wooden handle went with a Folders coffee can for cooling. I initially went with the coffee grinder look. I was told...

    Toolpost Grinders

    I also have a vintage Dumore. I made a mount that slips in and replaces the quick change tool post. It’s a little big for my South Bend 10L. I last used it to make a mandrel for forming bassoon bocals at the old shop. I’ve used it only once in 15 years.

    3” boiler project.

    I found the CO meter on Amazon. It was not expensive and reacts fast.

    3” boiler project.

    Update. I drilled a new .25mm orifice on the jewelers lathe. The burner is sitting in what will be the stand. I set the copper cylinder for the water feed tank to show that I intended to have actual boiler slip sit on top. It burns clean and even. I did make some adjustments to a packing of...

    3” boiler project.

    They have some serious machinery. I had to remove the piece to reheat multiple times.

    3” boiler project.

    The jet is removable so I can change it out. I knew it was likely too big. Testing is always done outside in open air to be safe. I am waiting for replacement drill bits. Sorry for the scare.

    3” boiler project.

    I will check it out. Thanks

    3” boiler project.

    I ran a mock up this evening. At low pressure it pulsates and there is some yellow flame at higher pressure. I don’t think it’s getting enough air. I had a .35mm jet. I think it’s to big. I need to replace my smaller bits and try .25mm and see how that works.

    3” boiler project.

    A photo helps. Basically building a carburetor from scratch. I am finishing the mixture tube and should be ready to test as soon as the regulator shows up. After I get the current burner working, I plan to make another using an internal tube as in your second version. I use copper because I...

    3” boiler project.

    Yes, it does. I am drilling out a mixing tube to 5/16”. I will start with .25mm for the jet. I ordered a propane regulator which should arrive tomorrow. Maybe I should install the view port in the boiler so I can see the flame in it’s working environment.

    3” boiler project.

    Thanks for the list. I ordered another piece of ceramic just in case. Have a tin that should work nicely for a mock up. My work space is well ventilated and with a CO monitor for the reasons you describe. You answered the question about what adhesives to use. I am designing a door with a...

    3” boiler project.

    Just spun a 3” base and rough fit a piece of ceramic plate. Used the mandrel I made for the boiler end caps. I thought I’d show the ceramic to make sure I have the correct material. Easy slip fit into the boiler.
