    Questions about bearing shells .

    You might want to get with a engine rebuilder to check for availability. Having the crank ground may give you more options of bearing sizes. Also line boring of the crank gives you more options.

    Trade New Holland hit& miss engine 1/2 HP 1/3 scale

    That all depends, do you have any small lead acid batteries, 3v,6v or battery trays to hold multiple dry cell batteries? Some people use their cordless tool battery. I don't know what the coil that you have can handle, you'll have to check to see if it gets hot.

    Trade New Holland hit& miss engine 1/2 HP 1/3 scale

    I see that there is a propane pressure regulator. The engine was being fueled by propane. As far as the wiring, positive to the switch through the coil to the post on the head. The terminal on the head should be insulated. Then ground to the base of the engine.

    Trade New Holland hit& miss engine 1/2 HP 1/3 scale

    Marks Kiln build

    dnalot The heat treat ovens that I maintained had a one piece platen floor over the bottom elements to protect the elements, as you have done. If the bottom cracks, the scale, ( oxidized material) would fall down through the crack and short the element. So, keep an eye on build up in the element.

    How to limit swarf into the chuck ?

    As stated earlier, there is excess clearance between the the scroll plate and the inside of the chuck body. Fill it up with grease and clean often. Don't blow air into the chuck!

    What kind of machine is this?

    Vary interesting! Quite possible that it was a vapor engine or a constant level vapor carb. There was a few very unusual engines from the Californian area. Thanks for sharing.

    is alluminium or brass better for steam engine pistons

    With an aluminum cylinder, powered by air, you would be better off using a nylitron, impreginated nylon. Why aluminum for the cylinder?
