I am back with another installment of the saga of making the connecting rods. Where I left off I had the three rods roughed out. I next went back and milled both round ends to finished size. At the same time I thinned one side of each end of the central part to the final thickness. This also...

Alexandre Thanks for the comments. I have been continuing on the piston rods. I should have more progress to report over the coming weekend. Eric

Stew The governor is a work of art. Great job Eric

Stew, Chuck thanks for the kind words. Now for this weeks update. As I planned I did get the cylinders finished and started on the connecting rods. First the cylinders. First I cut the six 1/8" brass air tubes just a few thou less than the height of the cylinders. I did not want them proud of...

Geoff Having build one of these engines I appreciate the work involved for the small linkages parts. You are doing a great job. Keep up the fantastic work. Eric

Stew, Eric: Thanks for the encouragement and thanks for checking in. No for this weeks progress. I worked on the cylinder heads and cylinder boss plus the breather. The heads were stared by milling the stock to the overall size and then drilling the clearance holes and drilling and tapping an...

Nicely done Stew :bow: I like the way you approach work holding and machining the small parts. Looking forward to the next installment. Eric

This weeks update on the build progress. I had limited shop time this week but did get to nearly finish the cylinders. Based on Stews comments, Thanks Stew, I made up a tool to cut the fines. I used a .125" diameter center drill that the tips had been broken off to grind a .060" wide tool. I...

Norberto, Don and Stew Thanks for checking in and for your kind words. Stew, also thanks for the plans that are the basis of this build. I got a bit more done on the engine this week. I started on the cylinders. The smallest stock I had that could be used for the cylinders was 2 inch round...

Next the bearing housing. This time I started with a 2 inch diameter piece and turned the mounting flange and the boss the fits inside the crank case. I also drilled and bored the bearing recesses. After drilling the screw clearance holes I made a simple arbor by turning a 1 inch steel rod...

It is the time for the next project. This time I have selected the Potty three cylinder air engine. Plans can be found on this site. I will be making some relatively minor changes to the original design including not using metric screws. I have modeled all of the parts and produced new drawings...

Great start to what promises to be a fine engine. Glad to see that you are back in your shop I will be following this build closely. Eric

Pete Your new / previously owned mill looks to be what is sold in the US as Industrial Hobbies. I bought a bare bones model about a year ago. Built my own stand and added the DRO. I have been VERY happy with my mill. I am sure that you will put yours to good use. Eric

What can I say that has not been said before :bow: The engines are a work of art and the build log inspiring and informative. Thanks for letting all of us share in the build. Eric

Navigator, Bill Thanks for the kind comments. Bill, I did find this small, quick project very gratifying. Now on to the next project. Eric
