SSA Convention
Tuesday, January 26, 2010
Static Lines
I need to get up to Moundridge one of these days and get some varnish for the new wood pieces. Leah and I are excited to head for the SSA Convention on Thursday night. We'll be spending the weekend in Little Rock hanging with all of our great glider friends and meeting new ones. I'll be working the SSF Booth when I'm not otherwise busy. Dean Gradwell should have gotten there today with N72DG in tow. Nice to know that a beautiful Cherokee II will be on display. In other Cherokee II news I got ahold of Eric in EAA Chapter 1111 out in Washington who has a Cherokee Fuselage and wing on display in his hangar. Quite an interesting story behind it and hopefully once I get pictures I'll make a post about it.
Hoping to get to work on Transponder mounting tonight. We'll see...

Trailer Covered!
This lead to some pretty major work in May and June to get the trailer roadworthy again. Leah and I and a few good friends were working out at Harry's most days each week. The old skin and floorboards were torn up, repairs were made to broken or seriously rusted portions of the frame, the whole thing was sandblasted, primed and painted. I put in new plywood for the floor and got the fittings back in the trailer in time for the Kansas Kowbell Klassic straight out distance contest in July. But the trailer still didn't have any skin! It was a drag, literally. With only the front and rear pieces of aluminum in place, it was about equivalent to towing two trailer. Maintaining a reasonable highway speed was impossible. Tailwinds helped.
I had bought some aluminum back in June for the job but just never went through with it. Partly I was dreading it because it certainly was going to be a major job. Second I didn't have a great place to do the work. Well with colder weather these last few weeks I knew I wasn't going to get much work done on the glider so I decided that maybe I should spend the time getting the trailer finished. I arranged for a few friends to help out this weekend and a couple of my power flight students offered the use of their shop which was awesome. I had a couple of air drills from harry, had bought a whole bunch of drill bits, a couple hundred clecos, 3 cleco pliers, a couple air powered pop rivet guns and about 1500 pop rivets.
We got to work mid morning on Saturday. First sheet went pretty well while we all (Leah, Joe, Jesse, and I) all figured out what we were doing.
We put all three top pieces on after attaching the bottom pieces. With all three of the top pieces cleco'd together we used some 2x4's and ratchet straps to bend them all over together so that the seams were flush. It turned out really good!
Here is the view of the right side before it was bent.

The view from inside. Looks great!
So I still have a few more things to do before I can call the trailer complete, but it is completely functional in its current form. At least I will be able to park it outside and the glider will be protected. Harry is working on some lip pieces to rivet around the front to seal up the gap there. Then I will have side running lights to install along with maybe some interior lighting and some tracks for the wing dollies. I also need to get a sheet metal strap or something to hold the wingtips in the wingtip cradles.
I picked up some 1/4" ID plastic tubing at Lowe's today along with some Tees so I can replace the pitot and static lines. Hopefully tomorrow I will have time to start installing that as well as fitting the transponder, encoder, and transponder antenna.
I'm still debating whether or not I want to cut out the shelf in front of the spar. Im a little nervous about putting the saw to that. Also, the plans show lightening holes on the keel underneath the cockpit, and my glider doesn't have them. I'm considering doing that too.

Glue!
We got an electric space heater which helped keep the temp above 50 F while we worked. Only supposed to get down to 46 outside tonight and back up in the mid 50's tomorrow. Here is the frame glued in place.
And here is the new support for the lower longeron:
And the filler piece next to the fuselage:
So we'll have to do some varnishing once the glue cures. Great progress made though! Jesse is here and after breakfast with the CAF tomorrow we will start Akasegelflugzeuganhangar or however you spell it.

Wingtip Cradles
I've made a few more updates to the Cherokee II Roll Call post. Looking through some of the old Soaring Magazine Archives I found some classified ads that I could ID to certain gliders. Interesting stuff.

Trailer Summit this weekend
Currently, my trailer still looks something like this:
which really isn't satisfactory protection from the weather. I've had a bunch of aluminum sitting at Harry's house since last summer just waiting to be put in place. So this weekend a group of us will be having a riveting party. I've got 1500 pop rivets to pick up tonight. Need to buy a couple hundred cleco's and a few more cleco pliers. I've got a heated shop for the weekend to do the work in. Should be a great time. Bob K has Akafleig's, perhaps I can have an Akawohnwagen??

Chiseling
It looks like I'm going to try to spend the weekend of the 23rd with a few friends riveting the aluminum to my trailer. That will be a relief to have it enclosed, finally.
I received a report that Ken Caldwell is flying his Cherokee this week at the Australian Vintage Rally. Hopefully he will send me some pictures when they are done and I can pass them along. He did say that it has been HOT there with several days above 100 which killed the flying spirit.

Cuttin Wood
I'm going to start working on figuring out a placement and routing for the transponder antenna and cable. Also need to work out a spot for the altitude encoder and something to support the actual transponder behind the panel. Need to make a shopping list at aircraft spruce for hardware, pulleys, and other stuff like that. need to replace it while i've got everything opened up.

Update and another Flight Report
I just received my latest copy of the Bungee Cord and see that Dean Gradwell's beautiful Cherokee II, N72DG, is featured for the month of July on the calendar. Very nice! I really like the VSA Calendar for the winter edition of the Bungee Cord.
Is anyone going to be at the SSA Convention in Little Rock? Leah and I will both be there and Dean is scheduled to have 72DG on display. I will likely be working the Soaring Safety Foundation booth most of Friday and Saturday unless one of the presentations really catches my attention. Looks like there will be plenty of good talks and good times to be had.
I'm still hopeful to get the fuselage more or less ready for fabric this month. After the fuselage is complete I think that I'll work on getting new skin on the trailer and then go to work on the wings. End goal is to be ready to fly by beginning of or mid April.
So in the meantime, I have my old computer up and running, so might as well pull some old flight reports off it and get it published for the world to read. Here is the report I wrote after my first solo cross country flight in a glider. Previous to this I had done a few cross country flights with my instructor, Matt Michael, in his IS28B2 "Lark", both ending in a landout which was valuable experience.
I had been looking forward to Memorial Day weekend for quite a while. I had purchased my glider, N373Y, the month before and had done my first flights in it the weekend before. I was pleased to find that it handled and climbed well, especially in weak lift. With a 25:1 piece of antique aviation all to myself, my next goal was to go for some distance! Watching the forecasts for the entire week before showed me that it would definitely be a downwind dash kind of weekend. Strong flow was predicted out of the south, but sunny skies and high temps were also predicted, giving me hope.
Arriving at the airport early Saturday morning to prepare for my flight, I wandered over to the towplane hangar to find Darrel Mullins mowing. Diane Bassham, scheduled towpilot for the day, drove up as I did, and Darrel reported that the Super Cub would not turn left. The tailwheel was not engaging. I was devastated. I would have had to get launched early (like right then) to beat prohibitive surface winds and get out of there. I also realized this was going to hurt chances of getting a flight in Sunday too. I went back to the hangar and worked on washing the glider and picking up some other loose ends. Lunch with Paul Kaufmann and Darrel was enjoyed while watching nearly gale force winds knock small children over. Maybe it wasn’t so bad that I didn’t get aloft.
The tailwheel was dropped off at club mechanic and storyteller Paul “Yeager” Mcilrath’s house Saturday night. I spent 11 hours at the airport Sunday, but was ground bound the entire time. I did install an electrical system in the ship as well as a good antenna and hookup for my handheld radio. Sunday evening I was delighted to hear from Paul saying that the tailwheel had nothing broken and should work, from what he could see. I crossed my fingers that it would work when reinstalled. Paul asked if I wanted to fly Monday, sounded to him like a blowout with 20-25 knot winds. I had talked to Tom Burns, the scheduled towpilot, and knew that if the wind was 25 or under, we both were comfortable flying. I had no intention of staying within glide distance of the
Paul came over to help rig, he decided to stick around and help me get launched. Also present were mentor Matt Michael as well as Leah Benson and Rob Gilbert. Tom also came over to help. With so much help, we quickly got the Cherokee assembled, and with Critical Assembly and Positive Control checks complete, were ready to pull down to the runway. Paul and I followed Tom to the active runway 19 while Matt and Rob got ready to crew. With everything prepared, all I had to do was jump in and take off. Leah and Paul helped hook me up and see me off. The wind was strong enough that no wing runner was necessary; the Cherokee is a great windjammer!
We towed straight out into the wind, in case I needed a relight. Lift was weak on tow, but I released at 1800 ft thinking I was in some great thermal. Of course I ended up being wrong. I drifted downwind towards the airport and couldn’t find anything. The lift was getting broken up by the wind and hard to work. I entered the pattern, and of course as soon as I did I found a little lift, maybe 100 fpm up. I worked it for a little while, but wasn’t climbing very well. Eventually I had to leave it as the airport was getting farther upwind and I didn’t have nearly enough altitude to try to set out over town. I probably wouldn’t have made it past the north side of town.
Tom had just landed the towplane and I landed behind him. Paul raced the Festiva back down to 19 and we hooked up quickly and off I was again. It was about the closest I’ve gotten to doing a touch and go in a glider, without landing on tow.
I wisely decided to take the second tow to a higher altitude, and got off in some weak lift at about 2500 AGL. I also had Tom take me further east of the airport where some better looking clouds were. Thankfully I found a good patch of 200 fpm up and was gone. I set off to the north, the 20 knot tailwind giving me a good push. After the initial climb I had trouble finding any good lift. Occasionally I would find a patch of rising air, but it was getting broken up and was impossible to work. Holding altitude was just as good as climbing and I took what I could get. Once north of Story city, I was approaching 1500 AGL and still going down. I started scoping out good landing sites, which I was surrounded by. Continuing to the north, I was now half way to Jewell and going through 1000 feet. Crap. I was sure that I was going to lose it and started to set up for an approach. At 800 feet, about to turn base leg for a nice field, I flew through a strong core, and it literally startled the heck out of me. After regaining my composure I turned back for it. I was unable to find the core again, but once again found some good 200 fpm lift that was semi steady. I worked it to my maximum altitude of 2800 AGL.
While on this climb I noticed I hadn’t heard from my crew in a bit, and then noticed that I had bumped the radio and changed the frequency. I regained contact with Matt and he told me they thought I had crashed into a field. Some confidence! I reported climbing to the north and was considering heading northwest as there looked to be some overdevelopment ahead. Once back in cruise, Matt reported that thunderstorms were building from
I immediately unstrapped and pulled out my phone to call Matt and let him know that I was safely on the ground. I also tried to estimate my position for him to come get me. I got out of the glider and saw some people at the house looking kind of funny at me. I waved to let them know (hopefully) that I hadn’t crashed and wasn’t dead. I started to tie down the glider when the farmer and his son walked out to meet me. I introduced myself and let him know my crew was on the way. I asked if we could derig in his driveway, and made very clear we didn’t want to damage any crops or inconvenience him. He had work to do, but helped pull the glider up to the house. As we were walking up, Matt, Leah, and Rob showed up. We got to work derigging, and in just under an hour were on the road.
We made it back to
Had a blast and finally got to put to the test all this cross country soaring instruction I’ve been taking.
