I finished up the gas cap, at least for now. I could make it a little
nicer looking with more filing, sanding, etc., or I could hope I
get a milling machine in this lifetime to make a new one.
Then I cut out the hole for the filler cap threaded flange
using an adjustable hole cutter. I had my doubts, but
I cleaned the tool up, sharpened the cutter bit, and
did a test drill in some scrap. The hardest part was trying
to get everything clamped down good on the drill press.
Had to do a little deburring, but the flange fit tight.
Next, onto the “vent”. My old vent barely stuck above the
top of the tank.
Is this how they left the Caille factory?
I see that Joe’s tank was the same.
Some other photos it appeared that the vent line stuck up
a ways. I decided to make it longer, figuring I could always
shorten it if needed. I could not find any 1/8″ OD copper tubing
laying around, but I had a loose carb off a Zephyr with a
slightly smaller OD that became a donner.
Next I need to “test mount” the tank to the motor to position
the bronze mount to make sure the tank looks square
to the motor, then drill the rivet holes.
I still have to experiment with the rivets after I fashion
some kind of tubular rivet set.
Prepare to be boarded!
