Another Internal Combustion Engine

[rwm]

It looks so good in aluminum and brass. I'm still trying to figure out how it works...

Thanks Firstram, Chris, and Robert.

There are a number of pieces missing but as the spool moves upward by the weights moving outward, the catch arm is moved over to catch and hold the rocker arm.

Thanks

Some of the governor parts.


And two views of the governor all assembled and installed.




I will have to get a stiffer preload spring and maybe a smaller drive pulley as the weights really fly out.
I am happy with the way it works so a couple of adjustments and it is ready to go.
I am going to disassemble the engine and paint it either red, orange, or blue.
Still haven't decided.

Thanks for looking

I keep getting fooled by these passively driven intake valves! I get it now. This is looking great!

Thanks Robert

The red and green spray paint cans were almost empty and the blue just wasn't doing it for me so Allis Chalmers orange it is.


I took a couple of hours to shine up some of the aluminum pieces.

On just about every model I have made I don't let the paint dry long enough and end up messing it up somewhere.
I have other obligations to do tomorrow so may not get any shop time on the engine.
Maybe the paint will be dry Friday.

Thanks for looking

The paint hadn't completely cured today so I put the pieces in the toaster oven for a few minutes.
While I was waiting on that I decided to cut the o-ring groove in the piston. I didn't have any o-rings the right size for this larger piston so I had ordered some from Graingers. I wanted 75 shore hardness and the calculated size in Viton rubber. I had looked in Mc-Master Carr for them but the smallest quantity they offered was 25. I don't think I will ever use 25 o-rings of this size. Graingers had a package of 10 and since I could pick them up from the store I went with them.
I should have read the description a little closer as these turned out to be square o-rings and I had never used that type before. Who knows they may be better for this application.


A couple of pictures of the current progress all shined and painted up.




The compression seems good but I won't know for sure until the head is installed.
Do you like the shiny water jacket top?


I will be gone for the next week or so cruising the Bahamas.

Have a great trip! On the plus side, the cruise line has a supplemental Engine mechanic onboard!
