The mittens are soft leather on the palms, and the inserts are fairly thin, if tightly woven, wool. I've no idea how they work in arctic temperatures, but they do. The trigger finger on them makes manipulating items easy, including writing. Since the plane is pretty much forefinger and thumb light in controls, no problem.

They worked wonders in the winters of Germany hanging out of the open hatch of an M113, and were a treat in the Nieuport.

The new cork for the fuel indicator was trimmed up a bit, re-shellacked, and is working a treat. The old synthetic ones became sodden and refused to float, which I found disconcerting. It's one thing to be "pretty sure" there is sufficient fuel and an entirely different thing to actually know there is sufficient fuel.

The squeal on transmit with the handheld turns out to be a common problem, and is most likely the cables from the handheld unit to the headset. It's not the antenna, as it squeals with everything removed from the aircraft and the rubber duck antenna on the unit. So I'm ordering new ones, as well as little thingiebobs that attach around the microphone cords. I suspect they're magnets of some sort.

Being a small, slow aircraft, one of my worries is runway or pattern incursion by another aircraft. A surprising number of folks with certified aircraft and built in radios don't use them around my field. I realize that it's not required, but it doesn't do any harm at all, and I like to call out my position to them. It's also one of the reasons I've been finding the correct - but smallest - pattern I can find to land and be off the runway at the first turn off.

Back about a hundred years ago (~1985) when I was training for my PPL at KGYH I was told to be wary of brand new biz jets flying in sans any radios, they were in fact arriving to have radios installed at a facility on our field.

I was out at the airport today to help a friend work on his KR2 when we realized that the weather was pretty darned good for flying.

When he got to a point where he didn't need my help, down I went to pull Babette out of the hangar and into the air.

So here I am, flying a small route around the aerodrome, well away from the front, when I feel it. I'm not alone. Looking around, up, and behind me, I'm shocked to see a Folke Wulf 149D at my eight o'clock, 1500 feet above and about half a mile off, stalking.

His paint scheme pretty much just like this:

A gallant salute (he had no ammo, so I spared him), and we went our separate ways.

Good luck when you get a chance at a Blimp....

I got wrote up (un-officially) by the FAA for attacking a Goodyear blimp near Vero Beach, FL circa 1972. The blimp pilot contacted me and we talked on unicom channel. He apologized for having to report me, said it was company policy...ada...ada. The Melbourne FSS, the closest FAA types knew me very well and it was much ado about nothing.

Nowadays it would prolly be a terrorist threat requiring a zillion dollar strategic redeployment of AD assets.

Oh...the blimp attack. I was in a Cessna 150 Aerobat, climbed to about 5500 ASL, he was at about 1,000 ASL, did a proper wingover, and wizzed by the astonished blimp types at an almost VNE of 130 kts!

I'm wrestling with the oil pressure right now. It's way too high, and I took out the two oil pressure relief valves, checked the holes for galling, cut the springs back a bit, and put them back in. No dice. The rear one had horizontal grooves on it, and I suspect it's the wrong one - it should be smooth - being the one used for the single oil relief valve VW engines.

So I'll go track down a new set of valves, take them out, cut the springs back a touch more, and replace the rear valve.*

* A bit of explanation of what the "valves" are. They're little cylinders pushed up into the paths of the oil flow by means of a spring held in by a bolt.

The front one has oil either going to the oil cooler or the sump. The idea is that if the oil cooler gets blocked up with something, it will divert oil back into the sump.

The rear one is the true oil pressure valve, as it has oil either going to the cylinders, etc., or the sump. The darned thing should be moving down against the spring a bit against the pressure, giving me 10 pounds for every 1,000 RPM. But it isn't moving at all, forcing everything into the engine...and there's no regulation of pressure. So the oil at 60 pounds of pressure has to go somewhere, and the only place it can go is out the prop hub.

It's all the rage to put in "heavy duty" springs to the point that one can't find the stock ones. They're grand if one's engine is worn out or running redline RPM's in a racing Bug, but no so much for normal operation. The response to too much oil pressure is to cut the springs back bit by bit until they act properly. Of course that means I need extra springs for when I cut one of them too short and don't get enough pressure.

I'm beginning to really, really, really hate mechanics.

Most likely the spring you have is an incorrect aftermarket item. They are too long if memory serves me. Go to www.thesamba.com and check the 'performance' threads. There was some discussion there about this just a few days ago. Seek poster 'Modok'. He is very knowledgeable.

Yep, there are a few "hot rod" parts in the engine, for better and worse.

While the replacement set I bought are after market, just by looking at the springs, it appears they match the originals closer - they don't look as robust or long as the ones in there now.

The wife was smirking at me for not rushing to the airport to put them in, as we've got another cold snap here. She thinks it's endlessly humorous that I don't flinch at flying in freezing temperatures but don't want to perform maintenance in them. The truth is that in the cold, when my hands get numb, I tend to over torque things and cut myself more.

'The Cold' is a story everyone has! When a young lad my autos (just a few car lengths ahead of the junk yard's tow truck) always had major break downs in Feb... the coldest time of the year, here. I wrenched them myself.... outside.... on the ground... in the cold, wet rain, sleet and snow using a few basic hand tools and an abundance of curse words. Trannys, blown head gaskets, burnt valves and etc. I could repair it or at least get them to a machinist for the work needed. My hands never hurt too bad until they got warmed up to normal temps after all work was done. You realize then and there that, yep, that hand slip DID slice the meat on the knuckle or that starter that fell DID catch the pinky finger. That's when 'The Pain' stories start! lol

Yep. Today is a hard freeze, this weekend will be in the 60's and sunny. Life Down South.

New plungers installed and the springs cut down to where the pressure is much better - still high, but not crazy, and I'm loathe to cut them down too much, as the oil will thin as it heats up. I should be able to take her up and around to check it out this weekend.

Culver Props started on my new one! The replacement they made for me was 60" long, when it should have been 62. Pretty neat that they're exchanging it with no cost - that's customer service! So next month I get to change it out.

That's pretty cool customer service with Culver! I'm a big fan of Golden Age Racing airplanes and have built a few RC models of them. One I still wish to build is Hans C. Rasmussen's 'Skippy'. Mr. R. was a very interesting man and worth an internet search. Mr. R. made everything on that airplane except the prop and the tires. His friend, Roger Lorenzen, supplied the hand carved prop! I wrote Mr. L. a letter a few years ago asking if he remembered the colors of 'Skippy' but he didn't. I still have that lovely letter in unsteady hand writing from a very nice and genteel man! Mr. L. has probably passed on by now but it was cool to have that tiny bit of interaction with somebody who was actually a part of that period of history... and he was a prop carver!

As far as those springs go cutting them back might not be the answer as the metallurgy is suspect and causes problems with elasticity and such. I have tried to find the thread about them but, alas, cannot. I'll keep looking.

Well, cutting them back seems to be the consensus from the folks I've been talking to.

She's still topping out at 60 pounds at full throttle, but down to 40 at cruise. A few spots of oil on the cowl at the end of the flight, but nothing serious. I may back off about a pint of oil in filling her.

I went out to the airport today to work up some replacement baffling seals for the engine, and after gluing them up, realized that not only was it in the mid 50's, but the wind had died down to almost nothing.

So up I went! Air was glassy smooth - it was like sitting on a kitchen chair - and I made the most of it in the hour and a half before the sun started to get low in the sky.

When the air gets thick like this she doesn't want to land! I went really long waiting for her to settle onto the runway!

Cutting a spring makes the compression rate stiffer. Springs are rated by installed tension, compressed tension and compression rate. If you really want to study springs, research springs for snowmobile clutches. The Yamaha technical update manuals from the 90s and early 2000s have good graphs showing the comparisons of some 20+ springs that fit into the same application.

If you have an arbor press, you can test the springs. You need to test spring pressure for installed height and compressed height. The difference is the rate. You need to consider coil bind (mechanical touching of the coils) and flex (the spring wanting to bulge outward when compressed). The length of the spring and coil thickness will affect coil bind. The fit of the spring within the bore and coil thickness will affect flex. You can mitigate the flex by placing a solid rod inside the spring coils.

I have the inverse problem - too much tension.

That is what I was getting at. When you cut a spring, you increase the rate. You decrease the installed tension because you have lessened the length. What affect you have upon the compressed tension will depend on the compression length and the rate.

I know it seems opposite, but a spring of the same wire diameter and material is "softer" when it has 10 coils then when it has 5. You have a longer wire that is flexing.

I know blahblahblah ..... I am counting rivets.
