Sante Schilderman's Farmboy Class Project

 Sante Schildermans from Belgium and his Hit & Miss Engine school (Wico-Campus TIO) graduation project.  Ready for an ignition system.

Update June 25, 2021:

Hallo, 

We didn't finish the engine due to the corona measures at school.  But here's a picture of what we did get.  We will continue to work on it next school year.  Hopefully the engine will run.  If so, I'll be sure to let you know.

Bye, greetings Sante Schildermans

Jim Gasowski's Farmboy #003-X2 (twice as big!)

Jim built Farmboy #003 back in 2009 and has just completed a version that is twice as big.  Looks great Jim!  I hope to see it at one of the shows soon.

 

Farmboy valve guide lubrication

----------------- Question --------------------- 

Hi Allen

I am slowly building the Farmboy HnM engine and have a question about the valve guides.

Having gone to the trouble of making the valves a nice fit in the guides I wonder where the lubrication comes from, and if no lubrication won't the valve stem get sloppy in the valve guide?

Having lots of fun & learning lots as well.

Thank you for your time.

Regards

David Tredenick

Hi Allen,

The valve guides need little lubrication. A drop or two on the valve stem every now and then is more than sufficient. With a little oil mixed in the fuel, the intake will also get lube. Also the exhaust valve which moves the most, may (?) get some lube from the unburned lube in the exhaust. After 11+ years I see no wear on mine.

Finally got around to making the sled for Farmboy x2. Should have a pic or two for you next week.

Take care

Mark Smith's Farmboy #801

It's sitting on a lazy suzan for the video thus the reason for the vibration.  He says it ran from the very beginning.  Nice work.  Thanks for sharing!

Farmboy mistake?

 Here's an email I got from Jim G.

-------------------------------------------------------------------------------------------------------------------

Hi Allen,

Was going over the plans that you sent me and I found a mistake. Page 10, Cam shaft / Governor lever pin, Pin length to the cotter pin hole shows .365". If you put that pin through the Cam Shaft (same page) the pin won't clear out of the square to install the cotter pin. I think the dimensions .430" and the length instead of .420" should be about .490".
