Below you can see a few photos of a cylinder that
I am getting ready to bore for a 5 HP Bovaird & Company, rare 2 cycle pumping engine. I will
be posting photos here of the different work I will be doing in the shop.
These (2) photos are of making a boring tool to bore the above cylinder that is set-up
on the Lucas Horizontal Boring Mill...
In these next (4) photos I made some axle stub shafts for a garden trailer. They were
pressed and welded in place...
This is a piston for an 8 HP Pattin Brothers engine I had metal sprayed and turned
down to the proper O.D. The rings grooves were also trued up. Notice the valve housing
for a Bessemer engine next to the piston. I am pressing a bushing in for a new valve guide on
that...
These next (3) photos are of a pulley being drilled and bored. and a hub being welded
into the bore. This is going to be on a old Briggs & Stratton running an old
compressor at the shows this year. Next I will turn a taper on the outside surface to
simulate a crowned pulley...
These (2) photos are of a wrist pin for an 8 HP Pattin Brothers oil pumping engine...
In these next (4) photos you can see the taper attachment on the LeBlonde lathe being used
to finish turning the O.D. of the pulley. The taper attachment worked out real well and if
you look close at the pulley you can see the 3 deg. taper, starting in the center and working
down towards the outside...
This photo shows the finished pulley and also a valve stem for a Bessemer flat intake valve
I am making which I just finished cutting the 5/8-11 thread on...
Here in these (3) photos you can see the O.D. of the 4" boring tool taking shape. In photo
#3 you can see the front faced off too...
Photo #1 shows laying out the boring tool on the surface plate. Photo #2 shows indicating
the vise to make sure its parallel to the table ways. Photos #3 & #4 show milling the boring
tool. Notice I didn't wind up using the vise from photo #2. I wasn't happy with the way the
tool was clamping up in the vise...
In these next (3) photos Ron Polle is working on a hub / spindle
for a cooling fan for his 5 HP Bovaird & Company engine. Photo #1 shows the brass being turned
down to the largest diameter needed. Photo #2 show some flanges starting to take shape. Photo
#3 shows Ron hard at work...
Well, finally all the milling is done on the 4" boring tool...
Drilling a hole in the fan spindle...
These (2) photos are of more work on the Bessemer flat valve. Photo #1 is of the original
Valve. If you look close you can see how badly worn the valve stem is. In photo #2 you can see
a hole bored for a small stem hub in a round piece of .500 thick flat stock...
Photo #1 here is of a needle valve for a outboard motor. I needed to turn off the first 3 threads
because they were stripped out. Photo #2 shows how the first 3 threads were removed from the main
housing of the carburator using the drill press so the needle valve could be installed...
Here in these next (3) photos Ron Polle is finishing up the fan
hub / spindle. In photo #1 Ron is finishing up drilling a 3/4" diameter hole in the hub / spindle. Photo
#2 show the spindle being cut-off to length from the main piece of brass. Photo #3 shows Ron in the
small Atlas lathe facing and chamfering each end of the hub / spindle...
This photo shows a couple of parts I had cut out on a wire EDM machine at work. One part is the latch
dog for holding the exhaust valve open and the other part is the governor weight. Also shown in the
photo is the hub / spindle for the fan. All these parts are for Ron Polle's
5 HP Bovaird & Company vertical...
These (2) photos are of facing a couple of 1986 Dodge pick/up truck front rotors...
In these (2) photos you can see a bushing / hub being made for the Bessemer flat valve. In
photo #1 I just finished turning the OD of the bushing and drilling a 5/8" diameter hole for
the valve stem. Photo #2 shows cutting the bushing / hub off of the parent material with the cut
off tool. Notice the small head / shoulder left on the bushing / hub for pressing the bushing
up against on the flat valve...
Photo #1 shows pressing the bushing / hub into the flat valve. Photo #2 is of the bushing / hub
welded in place. Photo #3 shows turning the OD of the flat valve. The final diameter and thickness
of the flat valve will be completed after the valve stem is welded into the bushing / hub. Turning
the flat valve from the valve stem will make everything concentric and perpendicular to the
center line...
In these next (4) photos you can see different stages of turning the intake valve and see it take
shape. Photo #3 shows and undercut on the inside face of the valve. Just the exterior part of
the valve will be ground, where the valve has to seal the gas off. Photo #4 shows the completed
valve ready for grinding...
Now we move to another lathe and set the toolpost grinder up to grind the valve. In photo #1
you can see the set/up used for grinding the inside face of the intake valve. In photo #2 you
can see the outside face all ground...
