In this photo I have finished milling the 1/2 wide slot in the rocker arm support bracket...
A 1/2" diameter hole gets drilled for the rocker arm pivot pin...
This .650 diameter hole is for guiding the push rod that will come from the governor assembly up to the valve chest...
For the Bovaird & Seyfang restoration I ordered all new hardware with the high crown heads. In this photo you can see what they look like and boy do they look nice. I bought them from Cook Enterprise, located in KY. They advertise in GEM magazine. The threads are rolled and the quality of the bolts is excellent. Can't wait to see them on the engine...
Well I talked to Joe Sykes the other day and he said that my Bovaird cylinder and piston were all completed and ready to be picked up. In these 2 photos you can see the cylinder and piston and the fine job Joe has done on them...
Below are 2 photos of what the cylinder and piston looked like when Joe Sykes got them from me...
In these next 2 photos you can see I have the cylinder and piston out of the truck. In photo #2 you get another look at how well the cylinder bore came out. I can't wait to get these parts assembled...
I moved the engine base and skid under the chain fall and got ready to mount the cylinder to the base. The chain fall really makes this pretty easy...
Here in this photo the cylinder is all mounted to the engine base and I put 2 of the mounting bolts in to secure the cylinder down. Now for some more cleaning and prep work on the cylinder...
Well I couldn't pass up taking a photo of my latest purchase. It is a 32 HP Buffalo Olin. I just moved it down to the engine area with my Ferguson TO30 tractor, and am getting ready to run it for the first time...
I moved the engine back up to the shop for some more cleaning and work on the cylinder...
Well I have a new addition to the shop. I bought a sand blast cabinet from Tip Tools. The cabinet works better then I had exspected. The quality of the material used to make the cabinet and the design are in my opinion very well done. I wish I had one of these cabinets 8 restorations ago...
The weather in late April is now starting to shape up here in Western NY. In these next 4 photos you can see the painting of all the various governor assembly parts and the bearing caps...
The base and cylinder now have a good 4 coats of primer applied. My friend Ron Polle came over to the shop and helped out with priming the base and cylinder and with a lot of other work on the Bovaird. Thanks Ron...
Now its time to start putting some of these painted parts together. Here you can see the governor assembly starting to take shape. It might be tough to see in this photo, but the tall crowned bolt heads really make the assembly look good...
The engine base gets its first 2 coats of red paint. The weather was just beautiful so I had to take advantage of it. The 4 coats of primer have had a good 6 days to dry so the timing was right...
Also the flywheels received 3 good coats of paint. In the first photo I am getting some instruction from my friend Stiles on the proper use of the paint gun. About 4 hours later with 3 coats of paint applied, you can see (in the second photo) how the flywheels came out. What a difference paint makes on the engine...
The time has come to put the flywheels and crankshaft into the engine base. I cut all the oil grooves into the new babbitt bearings and everything is ready, I think. Photo #1 shows the engine base on the trailer and the flywheels ready to be loaded. Photos #2 & #3 show the trailer under the hoist and the crankshaft and flywheels lowered into the main bearing journals. Now to suck everything back into the shop...
This is a photo of the wrist pin bushing that screws onto the end of the connecting rod. I shortened the connecting rod by 3/8 of an inch, (threaded end) and cut the large nut down 3/8 of an inch, which you can see in this photo. This will allow me to lower the compression and make for a smoother slower running engine. The bushing is threaded onto the connecting rod so I will be able to dial in the compression to what I want...
The throughs get a few coats of black paint and the bearing caps get fitted and shimed. Boy this is really starting to look like an engine again...
In these 2 photos you can see the governor assembly is now located and mounted in place...
Before the valve chest can be mounted, I need to remove some studs from the cylinder. I drilled a 3/8 diameter holes through the stud and tried to get them out with an easy-out but they were being stubborn. My friend Stiles stopped up the shop and I showed him what I was up against. In photo #1, he took the tourch and burnt the studs out without damaging one thread. In photo #2, helping us is Matthew (Stiles' Grandson) who was using the air hose to blow out the holes. What a big help he was...
