    T head engine by Brian

    A couple (3 or 4)pieces of pipe under the machine and you can roll the saw into place only lifting it enough to place or remove the pipes.

    IC Hit & Miss engine coolant.

    This is the product we use. I’m sure you could find the same or something similar in small quantities at MSC or mcmaster. Maybe even a free sample would be enough for a couple engines worth…

    IC Hit & Miss engine coolant.

    The machine shop I work in uses a water soluble coolant in our CNC mill that works very well. When the water evaporates out of the coolant overnight there is a residue left on the cast iron table or the tool steel vise/tooling. An oily film is left and we never have a rust issue. I’ll have to...

    A new attempt at making piston rings

    I have to agree with Steamchick. Honing gets rid of the ridges left by boring. Look at a bored or turned surface under a microscope, looks like a fine thread. Honing or lapping will take all the sharpness off the high points or smooth them completely if enough material is removed. Depending on...

    left hand drills

    I will grind by hand left handed teeth on the end of a solid hard shaft of appropriate size for broken screw removal( a little less than the tap drill size). Not really a drill but more of a flute-less left handed end mill. Been doing this for years and it works great. When using it I start with...

    T-Head Engine Plans

    I'm wondering if the valve stem and the accompanying adjusting rod tappet assembly need a definitive separation. That's a lot of weight and leverage flopping around as they motion and try to seat... Maybe a guide for the lower assembly and the valve stem just butts against a rod end. Just my...

    Hello every buddy

    Thanks, I have to finish a few loose ends on it then start another. Haven’t chosen the next subject yet but a few I’ve considered are a snow, a sideshaft hit or miss, or a vertical air cooled. Not looking to design it so depends on what i can find for plans I guess.

    Hello every buddy

    Hello everyone in the community. New, well seasoned, and everyone in between. I am a toolmaker by trade so have a wealth of knowledge to apply to the hobby. I got into the trade because I was fascinated with making things. 44+ years later I’m still cranking out parts for my employer and on my...

    Knee mill table power up&down

    I have a bad shoulder and cranking the table up or down on my knee mill was becoming quite a chore. So I made an adapter for my cordless drill to mate it to the handle connection. Had to put three flats on the 1/2” shaft to prevent it from slipping in the chuck. Works great and I grin every time...
