Thank you Larry. I am glad you are enjoying the build. As my confidence grows, so does my willingness to share what I am doing. Being relatively new here, at first I was intimidated by the very talented members and their amazing builds. I soon found that there was no reason to be...

Thanks Phil. The flywheel was done on a rotary table, no CNC. Check out post #27 to see how I did it.

I got all of the polishing done. Here is a picture of all the parts. When starting to make an engine there seems to be so many parts. Once they are all made there seems to be so few. I should have a runner by the end of the day.

This is also how I do it.

Thank you everyone for the compliments. It is good to know that people are enjoying the build. I have about half of the pieces polished. Hopefully I will finish it this weekend, although I think I said the same thing last week.

I usually don't deviate from the plans much, but I wanted to do something different with the flywheel as the plans have the same flywheel as my grasshopper. Here is what I came up with. I got the idea for how to hold the stock in the lathe to turn the OD from someone on this forum but I can't...

Here is how I drilled the holes in the internal gear. I turned a boss the same size as the ID of the gear, centered on a square piece of aluminum. I clamped the piece in the mill vise, and used an edge finder the locate the center. After clamping the gear on the fixture, I used my digital...

I believe your problem is that the overload switch is tripping. The on/off switch has a device in it that shuts the mill off it pulls too much current. If you notice the off button also says reset. When the overload trips you push the off button to reset it which would explain why it will...

I here is the orbiting gear. I didn't want to clamp on the teeth of the gear so I bored a hole in a aluminum block the same size as the OD of the gear, cut a slit in it, and clamped it in the four jaw chuck.

Here is the eccentric, valve nut, spacers, and piston rod screw. I did an inventory of the parts and all that is left is the flywheel and modifying the two purchased gears.

Thanks Vascon, glad you are enjoying the build. Here are the two pack nuts. There aren't many parts left to make. Hopefully I will have a runner this weekend.

Philjoe, thanks for the suggestion of the Bonzer but it looks like it may be too large for my machines. Cogsy, I have checked out a few Upshur builds on the forum and am thinking that I may go with the farm engine. I saw the video of yours running and it seems to run very well. Did you get it...

Here is the gear arm.

As I am getting close to finishing my sixth steam engine, I am thinking my next engine will be an internal combustion engine. I am thinking of building either the Webster or Jan Ridders Simple 2-Stroke. I am leaning towards the 2-stroke figuring that it may be easier as there are no valves...

Thanks for the compliments guys. Dreeves, yes the internal gear is very pricey, but this engine is too interesting not to make and you can be sure that the price of the gear will only go up. Here is the eccentric strap. I opted to make it out of one piece, instead of two pieces soldered together.

Here is the valve. This is about the smallest sized piece that I care to make. It seems as though the smaller the piece is, the longer it takes to make.

Here is the valve rod.

Up next is the steam chest.

This statement on Tom's website should explain why the links don't work. All the plans can be found here.

Got a few more parts completed. Here are the piston, cylinder heads, and valve plates.
