    Odd Camshaft design idea

    Just wondering........... Would it be possible to make cams using a filing rest on a lathe and a vertical slide? Indexing would have to be done obviously. Jack

    Hello from the Lake District

    Hi Nathan, I haven't built a Boll engine, but I've got lots of pictures and info. on it. Let me know if you want any. A diesel is quite a critical engine, as regards fits and tolerances, but don't let that stop you. You will learn quite a lot I'm sure. Best wishes with your one. Jack

    Fitting Oilite Bearings

    To load your bushes with oil, you can either submerse them in oil, then place in a vacuum chamber. As the air comes out, the pores will fill with oil. An easier way is to submerse them in oil and heat up the oil. As it cools down, the bush will absorb oil.

    Feasibility of small 4-cycles in practical usage?

    A 4-stroke engine has a lot more than half the power of a similar sized 2-stroke engine. The cylinder on a 2-stroke is never filled with a full charge. A lot of the fresh charge also goes straight out of the exhaust. In a 4-stroke, the valve timing more or less inhibits this, so the cylinder...

    Centring in a 4-Jaw Chuck

    I just watched a video on U-Tube which shows a very uncomplicated method of setting up a long SQUARE bar in a 4-jaw chuck. Place a piece of shim on the end of each of the faces of the bar, so that about half of it overhangs the end...... say 1/2", and hold them with a rubber band. You now have a...
