The picture was sent to me by Joe Baker. His grandfather was Ray Baker, the pilot you see in the picture. Joe believes the picture was taken at Packard Field, Detroit, in 1926. Thanks for sharing Joe!
I've been flying all week, so in my absence, Brian Eberle finished fitting the exhaust.
When you weld the flanges on the exhaust tubing, the weld material sometimes gets in the way of the nuts. You can see that in the picture here. Right now, it is impossible to get the nut on the stud.
So, the weld area is ground down to make room. You need to take enough material off to allow room for the nut but also allow enough material to keep the weld strong
The tube also had to be massaged a little bit to allow the nut to get started.
Here is another view.
A little smoothing with a hand file and the exhaust is now ready for its ceramic coating.
Lastly, Do you remember that nifty tool we used during the covering phase of the Jenny? The one that cut the pinked edges of the tapes so nicely? The tool that was so hard to find? Well, I got an email that may interest you.
