TV show "How It's Made"

[jdoran]

A little off subject, but:

A film crew from the Discovery Channel spent the entire day filming at our business. We make a machine that places and picks up traffic cones without someone needing to ride on the back of a truck.

They tell us that it will air sometime in January.

I had a great flight Sunday until I pulled my carb heat knob prior to landing. The knob came out about 6" !!!!

The clamp that attaches the inner cable to the lever on the air box had come loose. Is it a good idea to bend a little tab on the inner cable after it passes thru the clamp to prevent the cable from coming all the way out?

I have about a 45* bend on the end. Might help.

I wouldn't be real worked up even if mine came out in my hand. Owned 3 BC12's over the years and flew a gaggle of C-150's and 172's and never had a single case of carb ice. Dry, cold, wet, everything, storms, fog; nothing ever happened. I understand about 40 to 50 degrees F is about correct for getting carb ice, and we have a LOT of wet weather in that range here in the winter months. ZIP.

Did have a Datsun 510 sedan that I had defeated the intake heat on (I was young and stupid) and it would get carb ice every night in the San Francisco bay area winter fog. Got off work at 11:30 PM and the Datsun would do a standard carb ice pop-bang-pow as the ice went thru the engine as I came on the freeway on ramp.

Finally figured out what it was, hooked up the carb pre-heat again, end of problem, duh.

I believe I had my first case of carb ice a couple days ago with my A-65. I was flying at a low power setting. Like 1600rpm or so for about 20 minutes in very wet moist air. I applied carb heat to land and was surprised to have about a 200rpm increase in rpm instead of the usual decrease. Definently got my attention.

Would you tell me what your estimate of the outside air temp was at the time you got the icing problem. Want to see if it is near my notion of the nominal temp range for carb ice formation.

I havent reinstalled my temp probe since replacing my windshield but i'd estimate it was mid 50's deg F.

It's not so much temperature, as relative humidity.

We get more carb ice in the summer than the winter (especially when we DID have a summer, about 3 years ago!)

Relative humidity? I thought that was the fog that formed on the inside of the windows of a parked van in (pick the state you want to insult).

That has probably happened in every state

Had an Aeronca Chief w/ an A-65 quit with carb ice on final. 80*+ @ ~90% humidity day. Thought I was clearing it enough on the way down, (every 30 -45 seconds) Was going to be a bit low, so 'gently' gave it some throttle and the silence was deafening!

Now THAT's funny!

I agree, not bad for an engineer! (;f

Re: TV show "How It's Made"

An contractor, a salseman and an engineer were discussing whether it was better to spend time with the wife or a mistress.
The contractor said he enjoyed time with his wife, building a solid foundation for an enduring relationship.
The salseman said he enjoyed time with his mistress, because of the passion and mystery he found there.
The engineer said, "I like both."
"Both?"
Engineer: "Yeah. If you have a wife and a mistress, they will each assume you are spending time with the other woman, and I can go to the hangar and get some work done."

Keep this in mind: it takes 70 72 deg F to evaporate gasoline in the carburator. so at 70 deg airtemp it will freeze in carb!
Also humidety index has be considered but as rule off tumb!
