These 3 photos are of turning the stem and center hub for the gas valve.
I used tubing that had the DOM designation (drawn on mandrel) for the stem because the OD and ID are held concentric and to a very tight tolerance....
A grinding stone was dressed on the lathe and expoxied to a mandrel for grinding the main valve seat. You can see I rotated the stone and mandrel with a drill motor and a piece of short radiator hose. I had to dress the stone 4 times before I was happy with the seat. Also to keep the stone clean between dressings I used a file brush....
This is the diamond dresser and wheel in the lathe....
Below is a view of the valve chest showing the guide rods for the gas valve. They also have springs on them to keep the huge flat valve up against the seat...
These next photos show the latch assembly and slide parts...
Here is a photo of the governor before disassembly....
The wood for the skid gets cut to length...
The governor shaft needed a lot of work. I had to build up the bearing surface with weld and then turn it down to the right diameter to fit the reamed hole in the main latch housing...
These next four photos are of the machine work being done on the 80 tooth cam gear. This took my lathe to its limits but did a good job getting the gear done...
Here I am making a new cam shaft that will get pressed into the 80 tooth gear...
My son Joseph doing some of the cam nut lathe work...
The skid gets assemblied and the engine base located on it, ready for drilling the mounting holes...
This is the cam and latch mechanism assembly all together before painting...
A friend of mine "Morris Bridge" helps out on the lathe...
These are the plates that I welded to the bottom of the threaded rod that will go through the skid and engine. I routed a pocket in the bottom rail of the skid for the plate to be inlaid into...
This is a view looking at my shop on the east side. You can see the exhaust pipe for the 5 HP Economy that runs the line shaft. There is also a steam whistle mounted on the shop wall...
Here I have welded 3/8 thick X 3 1/2 square plates to the threaded rod for holding the skid together and mounting the engine to the skid.
Making the 2 stage cam out of 1/2 inch thick material. You can see the rough outline of the cam in the lathe. The next photo is the finished cam and then where it mounts on the governor and latch assembly...
There also had to be a keyway cut and a special key made. This was done by boring a 3/8 hole in the cam shaft and pressing in a pin with 2 flats ground to fit the keyway in the cam. This is how the original one was done. The original parts where beyond saving...
The governor and latch main casting gets a coat of primer...
The governor ball pivot holes where worn egged shaped and ready to break out. What I did here was use a Henrob 2000 tourch and fill the hole with steel rod and then re-drilled and reamed the holes for a new 3/8 diameter pivot pin. Here you can see the hole on the end is filled with weld and ready for drilling...
With all the holes drilled in the skid and the pockets routed in the bottom skid runners for the steel plates the base is now mounted to the skid...
I now put the base and skid on my trailer and put the cylinder on up in the garage where I had been storing the cylinder and piston. It was easier to mount the cylinder there then handle the cylinder 2 more times to get it down to the shop. I then put the engine back down to the shop. Some times handling this heavy stuff can be a challenge...
In these next 2 photos you see the piston and the bore which have all been machined and new rings made. I had all this work done by Joe Sykes in Lockport, New York. He really does great work...
With the B & S now down the shop I put the boys to work on her...
The cylinder and various parts receive a lot of primer and paint...
The valve chest is all painted and assembled...
I made the hot tube base and burner out of an old cast iron gear. Here you can see some turning of it on the lathe. After a lot of drilling, tapping, and milling you can see here how the hot tube, chimney, and burner base turned out...
The governor and latch assembly are painted and assembled and ready to go. What a lot of hours spent on the valve chest and governor assembly, all enjoyable though...
Morris doing more work on the lathe making some collars with set screws in them for the push rod shaft...
Morris also machined the check valve seat. Can you tell by his work he has run a lathe for 33 years...
I had to have a tag recasted for the B & S and you can see it here mounted on the cylinder...
Push rod is machined and collar made with it all ready for action now...
