Little Kathy and me part 7

Hello Ladies and Gentlemen.

Now it’s time to take care of the last thing, about the valve.

First some turns in the lathe for making the valve chamber.


As you can see at the plans, there are same channels that have to be drilling and milling. Here I have also make the top screw. 

Next, some turns again in the lathe for making the valve.

This is the valve road eye. First some turn in the lathe again, then treading for connections with the valve.

After that, drilling for connections with the eccentric strap.

And now, the eccentric strap, first cleaning and planning in the lathe.

Center drilling for connections with the valve road eye.

Then drilling and milling..

and some threading.

Some cleaning on the eccentric strap.

And now, all the parts are finish.

I’ll just have to mount the engine, so I can see how she is coming out.


Do not believe that she is finish yet. It’s now the real building begun. She needs lots of adjustments. As I know for now, some parts have to be redone. I have replaced some of the ugly allen bolts, but not all. After that all the painting need to be done. I am not  100% shore about with color I shell choose,  but I am thinking about  greyish blue.

Around the cylinder, I am thinking to cover with some wood strip, stain and then  seal with sealing.

So this is for now.

I’ll be back

    Never made anything before but decided to try to build a little kathy.
    The instructions and directions are pretty useless without seeing what you did.
    Thanks for the great photos.
    I tried doing it with just a little lathe and a belt sander, but needed the use
    of my brother-inlaw’s bridgeport mill to get the crosshead and crosshead slide made.
    Still working on the valve and piston parts.
    I’m trying to take photos as I go…hope to publish when finished.
    again..thanks a lot for your photos
