The last part needed before I can do some more running and test the hit ‘n miss governor, is to mount the hall effect sensor and timing magnet for the ignition.
I made a block to mount the hall effect sensor.
The hall effect sensor and block mounted on the engine.
To mount the timing magnet, I made a ring from aluminum and it will be secured on the crankshaft with a set screw.
Now that we have all the pieces together, its time to let the engine run some more and see how the governor works.
I gave the engine a good shake down run and I’m very pleased how the engine runs.
After running the engine for a while, I started noticing a couple of issues I’ll need to address.
The first and biggest issue, is my built up crankshaft. I was getting a bit of flex in it, and with the big flywheels, there was a definite wobble noticeable. Even though my idea of building it up the way I did was a failure, I’m OK with it. I had to try it, and that’s how we learn.
Anyway, I’m remaking the crankshaft. It will be built up again, but the more “traditional” way.
First, I milled out a couple crank webs. As I was at it, I made a small cosmetic design change to the webs.
I used a boring head to bore the two holes, to ensure that they are accurate and parallel.
The shafts and pin are made out of drill rod, and are ready for assembly.
I assembled the crankshaft with Loctite and set screws, and it’s ready to go back into the engine.
An other issue that needed to be addressed was the latch. I made the first one out of brass. It wore out very quickly, which was no surprise. My intentions where to modify it by attaching a small steel plate, that could handle the wear. Unfortunately, in the process of modifying, I messed up the part.
So I had to make a new one. I decided to make it out of O-1, and harden the business end of it. That will take care of any future wear issues.
First, I milled out the part. Second operation was in soft jaws to mill off the rest of the material and mill it to thickness.
And the latch back on the engine.
