These next (4) photos are an update to the babbitt bearings that Dave Johnson and I poured for his
15 HP Titusville Olin. After a lot of work on Daves part, the crankshaft is all fitted and the oil grooves
are all cut in. To see the prior work on the babbitt bearings,
Well here in these next few photos you can see I have started working on a lead screw drive
mechanism for the Lucas Horizontal Boring Mill. What it is going to do is power feed the platen
the entire length of the machine bed. The boring mill power feeds everything else on the machine
except the platen so I designed a drive system using AutoCad and am starting to make the parts.
Photo #1 shows turning the OD of the drive sprocket adapter. Photo #2 is of the drawing I am
working from. Photo #3 was taken from the AutoCad design file and shows the drive system and how
it mounts on the Lucas. Photo #4 shows the adapter starting to take shape and photo #5 shows
parting off the adapter...
In photo #1 I have turned the adapter around in the chuck and am facing it off to the proper
length. Photo #2 shows drilling the hole getting ready to bore. Photo #3 shows boring the hole
to a diameter of .967. Photo #4 shows tapping the adapter for (2) set screws and photo #5 shows
the dapter all completed and mounted on the drive shaft...
The next part to make is the idler shaft. Photo #1 shows turning the OD. Photo #2 shows drilling
a .257 diameter hole for a 5/16-18 thread. Photo #3 shows tapping the hole in the lathe and photo
#4 shows the completed part...
The next part to make was the main plate for the drive assembly. I went over to my friend Dave
Johnson's shop to have one burned out on Dave's automatic burn table. In photo #1 you can see Dave
setting up the drawing which has a black outline of the part to be burnt that an eye follows and
guides the cutting torch. Photo #2 shows starting the burn. Photos #3 & #4 are of burning
the part. Photo #5 shows the completed part. Boy do I wish I could cut with the torch that good.
While at Dave's shop Stiles Bradley and I picked up a cylinder and crankshaft from a 18 HP
Electric Lighting Buffalo Olin that Stiles is restoring. Dave was doing some work for him and it
was ready to bring home. In photo #1 you can see the crankshaft all turned and ground to a like
new condition. Photo #2 shows the cylinder ready for action. All the cylinder needed was a good
honing and it looks like new too. What a great job!...
Next, plans were made for Dave to hone the 3 HP Pohl engine that I just finished boring. Photo #1
shows lowering the engine onto the really super long power honing machine. Photo #2 shows the hone
all set up, the coolant running, and were ready for action...
Photo #1 is of Dave checking out the diameter we finished at which was 4.058. Photo #2 shows the
completed job and boy did it come out great. Thanks Dave for all your help. I think this diesel is
going to have good compression...
Back to work on the drive system for the Lucas. In these (2) photos you can see the hole pattern laid
out on the main plate for the mounting holes and the (2) holes that will hold the support bushings for the
drive shaft and lead screw...
To be able to mount the main plate in the machine vise on the mill, I had to weld a piece of 1" square
stock to the backside of the plate. I will cut it off after all the holes are drilled and bored...
In photo #1 I am using a wiggler to pick up the center of one of the mounting holes. Photo #2 shows center
drilling the hole and photo #3 shows drilling the hole to a .406 diameter. Photo #4 shows boring the hole
for the lead screw support bushing. This hole needs to be a diameter of 1.125...
Below are a few more photos of Dave Johnson's 15 HP Titusville Olin restoration. In photo #1 you can see
a new keyway being machined into the crankshaft. There has been a lot of work put into the crank and it
has turned out better then new. Photo #2, #3, & #4 show different stages of getting a flywheel on and of
mounting the engine on the skid. Photo #5 is of the brass tag for the engine, after it was all cleaned
up. Before too long, I have a feeling this Olin will be running...
This photo shows all of the purchased parts for the Lucas drive system. There are (4) sprockets, (2) master
links, (2) half links, and 3' of #35 chain. I ordered the parts from
Now that the 3 HP Pohl cylinder is bored and honed and we know the diameter of the finished bore, we can
get the piston metal sprayed and built up. In photo #1 I am pressing the wrist pin out of the piston and
connecting rod. Photo #2 shows it all disassembled. The wrist pin and connecting rod bushing look to be in
very good shape. Photo #3 shows the piston all cleaned up. I had to remove 2 pins that keep the piston ring
grooves from lining up. The pins were only in grooves #2 & #4. There will need to be new pins put in
after the piston is metal sprayed and the grooves recut...
This photo shows more work that Dave Johnson is doing on his 15 HP Titusville Olin restoration. Here after
welding the existing keyway up with Ni-Rod, you can see the setup Dave is using to broach the new keyway
in the flywheel hub...
These next set of photos are of Stiles Bradley pouring the main bearings for his 18 HP Buffalo Olin,
Electric lighting restoration. In photo #1 you can see getting the babbitt ready to pour. Everything must
be hot to have all the moisture cooked out. Photo #2 shows cleaning the lower bearings after the pour
to get ready to pour the bearing caps. Photo #3 shows the lowers all poured and cleaned up...
Photo #1 shows getting the moisture cooked out of the bearing caps. Photo #2 shows the crankshaft back in
position and sooted up so the babbitt wont stick to it. Photo #3 shows the setup with everything hot and
all the daming material put around the bearing caps. Photo #4 was taken right after the pour and photo #5 shows the
finished caps right after we took them off. They still need to be cleaned up...
