Thank you gentlemen for the kind comments. I agree. This is a very nice mill engine. Quite powerful as well.

Thanks Jason for the reassurance on the settings. I found this diagram quite helpful as a starting point. It's amazing how just a little adjustment of the valve eccentric makes all the difference in the world. Try one setting, the machine locks up and won't move. Move the eccentric a tiny little bit and you are off and running.

Also. having the eccentric adjustment boss on the outside of the part saves a lot of time and frustration. You have complete and infinite control of the eccentric.

Bill, that set screw in the floating valve nut was a gift. Again, infinite and instant sliding movement back and forth possible. No threads.

I may have to give that sliding nut a try John. I understand the benefits now. Glad it worked out well.

Yes Bill, worked like a charm.

Here's a quick look at the completed engine without its governor. It will have to be removed from the engine room to complete the workbench and other items at the back of the room.

Lovely "chuff-chuff" sounds.

Thank you all.  :D

Hi Tin,
Your idea of leaving the right side of the parting tool a bit long (grinding the tool on an angle) is working well here. This is a deep part as the governor drive pulley is being cut from a round of mild steel.

Hello John,

Just beautiful and even better in that setting.

Have a great day,
Thomas

Thank you Thomas.

You are right about the setting. I removed the engine and set it on a table so that I could work on governor parts on its back side. The minute I stepped back and looked at it, I realized it had lost much of its presence. It was just a model sitting on a table.

Now to drive the governor. Two friction pulleys have been made out of mild steel. I think a large 0-ring will be the belt material.

Thanks Bill.

Yes, the governor will add much to the presentation of the engine.

The first step was to find a way to transmit power from the back of the engine to the front. Bearings were fastened to the sides of the cast iron base. This was no small feat. The walls of the cast iron base are angled and the mounting holes had to be drilled with an electric hand drill. Shims may still be neaded to keep the mountings perfectly vertical. Tightening up the bolts has a tendency to cant the mountings inward. It was difficult to get the perfect angle for them during fabrication.

I tried Adam's idea of experimenting with B&W the odd time for effect. Here is the goveror drive shaft bringing power to the front of the engine.
