Photo #1 shows the new wrist pin being drilled to accept the set screws in the piston. Photo #2 shows
the completed wrist pin next to the old one. Photo #3 shows the new wrist pin assembled in the bushing
halves and ready for assembly into the piston...
The first photo here shows the wrist pin, bearing halves, connecting rod, with set screws tight, all
assembled. Photo #2 shows the piston pushed into the cylinder bore in preparation for installing the
rear bearing. Photos #3 & #4 show the back bearing installed to turn the flywheels over and
move the piston back and forth in the cylinder. What a great thing to see. The main bearing will have
to come off again to put the water ring on the back of the cylinder...

Photo #1 shows the ring that mounts to the back of the cylinder to close the water jacket off. It is
put in the lathe for cleaning and polishing. Photo #2 shows the first side and outside edge after
cleaning. Photo #3 shows the opposite side before cleaning and photo #4 showing the completed ring. I
think it's the lathe that needs to be cleaned / chips removed!
Six new studs had to be fabricated for mounting the ring to the cylinder. This photo shows how I turn
the stud to length and face the crown on the end...
This photo shows all (6) studs installed, gasket cut, and some sealer applied, with the ring ready to
be installed...
These (2) photos show the back ring all installed with the nuts torqued down after the position of the
ring around the piston is established. This is critical, that the piston doesn't hit the ring as it comes
out of the cylinder...

Went down to the Coolspring Power Museum to finish
up some work on the 25 HP Swan oiling trees. These (2) photos show the tree for the crankshaft and
connecting rod bearing completed. Still need to gather an oiler to finish the tree up...
These (2) photos show the oiling tree built for the cross head. Need (3) oilers for this tree which
will oil the cross head connecting rod bearing and the (2) cross head ways. Notice the wiper laying
on the cross head. I need to cut a 1/4 NPT thread on it, so it can be screwed into the bearing
strap...
This photo shows the (2) oiling trees on the Swan. It will look better when I get all the oilers
together for the trees...

valve stem...
Photo #1 shows the intake valve cartridge assembled and ready for installation. Notice the nut and set
screw on the end of the valve stem. Photo #2 is another view of the intake valve cartridge ready for
installation...
These (2) photos show the intake and exhaust valve cartridges installed in the bottom of the cylinder.
Notice the oiling cups for lubricating the valve stems installed...

With the intake and exhaust valve cartridges installed a new gasket was cut for the exhaust pipe
mounting box. Notice the separator partition that separates the exhaust valve from the exhaust port
in the cylinder...
These next (2) photos show the exhuast pipe mounting box installed...
Here a new gasket is cut for the intake pipe mounting plate...
This photo shows the exhaust pipe mounting box and the intake pipe mounting plate installed on the
bottom of the cylinder...

Photo #1 shows the pivot shaft for the rocker arms cleaned and tried in the bracket to make sure
everything fits okay. Square head set screws are used to secure the rocker arm pivot shaft. Photo #2
shows the side shaft support bracket secured with all the proper hardware...
These (2) photos show the intake and exhaust rocker arms in place. The cams still have to be installed
so the rocker arms will have to come off to install the cams on the side shaft...
Here in photo #1 the governor assembly is cleaned up. Photo #2 shows the governor assembly installed.
New shims were cut to achieve the proper clearence between the side shaft and the top bearing cap
which is part of the governor assembly...
These next (3) photos show finishing up a couple of loose ends. Photo #1 shows new brass screws
holding the tag onto the cylinder. Photo #2 shows a gas cock installed a long with a brass valve for
a compression release. Photo #3 shows the cover installed over the side shaft gears...
This photo shows a small governor part that I need to make. This is the part the governor weights use
to move the latch arm up and down. This one is worn real bad so (2) will be made up...
In photo #1 the cams are slid onto the side shaft. Photo #2 shows the drive dogs / catches put in place
with the springs behind them. Photo #3 shows the cams in place and secured to the side shaft with (2)
mounting screws. Photo #4 shows the rocker arms installed...

In photo #1 you can see a piece of square stock put in the collet for turning the end down to .312
diameter. Photo #2 shows the finished diameter (camera focus is bad). Photo #3 shows facing the
opposite end of the pin also finishing the pin to length. Photo #4 shows one of the finished pins...
The first photo here shows the (2) pins installed in the governor arm and slipped into the groove
under the governor balls. This is the arm that moves the latch in and out. Photo #2 shows the other
end of the arm and the latch. Photo #3 shows the entire governor assembly...
These next (2) photos show the brake band cleaned up and installed over the cam barrel. This puts a
drag on the cam barrel...

Well on Saturday the 22nd of October the 25 HP Columbus was ready to start. After checking things over
on the engine Saturday morning, Stiles Bradley came up to help and we started the Columbus. It took a
little bit to get the gas figured out but after that the Columbus was running! These next (3) photos
were taken during the day Saturday...
These next (3) photos were taken Sunday the 23rd of October. We made some changes to the governor
springs, advanced the timing, and added a cylinder oiler before starting the Columbus on Sunday. After
a few friends came over we started the Columbus again. It started on the first try. We ran the Columbus
for about 3 hours and we all enjoyed every minute of it. I don't have to tell you how happy the guy in
the 3rd photo is...
Below are (5) videos taken on October 22nd & 23rd of running the 25 HP Columbus for the first time.

After putting quite a few hours of run time on the Columbus, it's time to start working on some of the
small problems to fine tune the engine. The first thing I wanted to do was to take up the clearance
that existed in the main connecting rod bearing. Photo #1 shows the bearing removed from the connecting
rod. At this time an adjustment was made to the wrist pin bearing too. Photo #2 shows measuring the
ID of the bearing brasses and comparing it with the OD of the crankshaft journal...
Some material had to be removed from one of the brasses. Photo #1 shows setting this up in the mill.
Photo #2 shows starting to take the first couple of passes. Photo #3 shows the completed brass after
the milling and filing (deburring) finished...
Photo #1 shows the completed bearing set after measuring to verify the ID of the bearings and OD of
the crankshaft. Photo #2 shows everyhing all back together and the engine ready to start to see how
are adjustments work out...
