Curtiss Jenny Restoration

Welcome! We hope you enjoy following the restoration process of a 1918 Curtiss JN4D Jenny. Once completed, the aeroplane will be flown and displayed at the Candler Field Museum in Williamson GA (30 miles south of Atlanta). You can contact me below by clicking on "VIEW MY PROFILE"

Lower cowl brace

I wanted to get the rudder bar completed and two bushings were needed to do that. So, a piece of round stock was drilled for the 1/4 in. bolt...

And turned to fit the rudder bar bracket.

You can see the bolt in place with the new bushings.

I am about to start making the sheet metal so one last brace was needed in the fuselage. This piece goes under the front floorboards. The end of the belly sheet metal attaches here.

So, some 1 in. spruce was cut to size on the bandsaw.

Sanded smooth on the spindle sander.

Here is a shot of the left side.

And the entire brace.

The brackets were made from some thin sheet steel.

Rounded, drilled and countersunk.

This brace was given a coat of varnish and the brackets were painted in primer. Since I mixed a batch of varnish, the instrument panels were given one more coat too.

More soon. Enjoy

Oil Temp

In the last post, I mentioned the need to modify the Hisso oil screen plug to accommodate the oil temperature bulb. I was going to do some welding but Mike Damiami e-mailed me with a suggestion.

He mentioned the availability of an oil temperature probe adapter sold by Aircraft Spruce. I ran over there and Mike was right. The adapter fit perfectly!

Mike, by the way is a Tech Rep for Lycoming in Williamsport, PA. When he is not working, he spends most of his free time tinkering with the old engines and airplanes at the Golden Age Air Museum. I appreciate the tip, Mike!

My goal has been to get all the little things done between the firewall and the tail post. Things like cotter keying every bolt, safety wiring the turnbuckles etc. One of the last things to do is put the little leather anti-chaffing disks in between every wire in every bay. Nothing fancy. I sharpened the end of a piece of tubing and hit it with a hammer to cut out the disks. Tedious, but pretty neat.

Ron and I reinstalled the engine and radiator so sheet metal work can begin. We are also running all the lines (oil temp, water temp, electrical etc) and having the engine in place is a big help.

When we installed the water pump, it did not fit. My pump was one of the new parts manufactured by Denny Trone. We noticed that the pump shaft was bigger than the drive!

So, the impeller was pulled out of the pump.

This is where the pump mounts.

The drive was removed which gave me a good look at the oil pump, too.

Here you can see the differences in the drive and shaft. The shaft will go to the machine shop this week.

The oil temperature bulb goes into the oil screen housing. Should be an easy installation, right? It didn't work out that way!

The bulb threads into the cap, but there is no lip to stop the bulb from going forward. So, that has to go to the machine shop also for some welding and machining.

Lastly, the booster mag lines were made. I got some of the 16 gauge cloth covered wire from the Brillman Co. and installed the ends with a crimper.

The wires were fished through some special old time automotive style conduit up to the firewall.

That's it for now....Enjoy
