I spent the last couple of years puttering around fixing my anphib floats.  A blade departure took out the nose gear, among other things.   I finally got them done and back on the plane. When I tried to cycle the gear it was binding...the Johnson bar would not budge.   I removed cables and isolated it down to the passenger side main gear.  The cable was seized.  I got a good grip on it from inside the float, and with someone working the Johnson bar it came loose.  The section inside of the cable sleeve was covered in rust. Rubbing it with my fingers the strands disintegrated.  I checked the other side and it was going the same direction, only not nearly as bad.  All of the other cables are fine...shiny silver everywhere.  It was only the main gear upper cables...the ones that run into the cabin.  Checking the drawings, all these cables are speced as stainless steel.  I am going to take a section in and have it looked at ... but I am betting the ones that went are really galvanized vs SS.   The fittings are identical to the others...so I am betting it came from the factory this way.  If  you are running these floats...have a close look at your cables.

Aercoet  has nothing to do with 1100s   anymore Deke.

 I have SS cables on mine.

The rights for the floats have passed thru several hands.  A friend was looking at my serial number...and it could be I have number 3 off the line.   

 

For those who checked and feel they have SS..check again.  In the cabin, the cable looks very much like the other cables.  Not sure how  you can really tell without removing it and having it tested.  Anyone know of a test for SS that is quick and easy?

Use a magnet --- if it’s stainless the magnet will not be attracted. If its steel, coated with zinc then the magnet will be attracted to it.

Ted, 

  

 Stainless steel  comes on many grades.   You cannot say that all SS is not magnetic because that is not true.  

 I just went out and check over a bunch of SS  hardware on my floats  .  All AN SS bolts and nuts very strongly  attracted to magnet. 

 SS cables  -- gear cables   1/8 and  3/32  were magnetic but less  than the AN bolts. 

 1/16 cable for water rudder were magnetic as  well.   I think the hardness of  the stainless steel  might  have something to do with the magnetics of it. 

 We have a SS Fridge and magnets do not stick to it  but yet the Kids run into the freezer door on bottom and dent it . Go figure !!!  

  

 Also  I think most hardware on the Aerocet  floats are made from 303  or 403 grade SS and it is not allot stronger than  mild steel. I will guess 30% stronger.   Whereas  4130 will be 40  to 70% stronger than the SS.   

  

 When Dan Denney got Hamilton Stoddard to make   the 1100 floats he insisted on SS so they would fit all applications and have no  corrosion issues.  

 I have replaced some of the amphibian gear parts  with 4130 and it is stronger now.   The Aerocet 1100s are a decent  float in straight or Amphibian operation.  They aren't made anymore but  still a few sets around with happy owners.

You are correct there are different types of SS. However, you can still determine, reasonably close as to whether a piece of material is more towards ferrous or more towards nickel by the amount of attraction it has for a magnet. I have quite a selection of different grades of SS sheet and hardware and when I need something requiring corrosion resistance and strength is not a factor then I select a piece which has very little magnetic attraction. These are scrap pieces of material I got from a fabrication shop and the entire grade marking are no longer visible, so a magnet is a pretty simple way of judging whether the piece has high stainless consistency or is more towards the ferrous side.  

   

   

Thanks for you comments

 test the cable with a good  strong magnet.   Stainless is non ferrous, won't rust and won't stick  to a magnet.

I like my 1100s only wish they  were amphib!

Magnetic ? 

300 series stainless is non-ferrous and should be non-magnetic but... can become magnetic with cold working.  



I'm not sure but the rolling of thread on an AN bolt may creating slight magnetic attraction.  SS wire is also worked (drawn) so will probably be mildly magnetic.



400 series stainless is ferous and is magnetic.

A test

My experience with stainless wire is  mostly with sailboat rigging.

Sometimes sleeved cable in use on a sailboat for lifelines around the hull. This is one wire you don't want to count on - but if needed, you don't want it to break!   There are plenty of poor grades of wire - mostly with a clear sleeve.  If rusted, the rust color should show the stain.



A good way to 'test' cable (wire rope) that is intended to be flexible would be to bend it slightly - and expect it to 'feel' flexible with some engergy to return to the orginal shape. Rusted or over worked wire will feel stiffer (not return) or .... you may even feel the strands break as you bend. If it does not feel very flexible or looks bad... it probably is.

My rudder cables that were part of my 1995 S5 kit were specified as SS and

appeared to be SS, but a magnet would show attraction.  Not as much as 4130

would, but it definitely indicates that they have some iron in there.  I

suspect it's an alloy that has just enough nickel to keep them flexible and

corrosion resistant.

I haven't got a clue about metallurgy.  Just my experiences.

Deke,



Yes that is my findings on my SS cable and hardware today.  AN SS hardware 

had more attraction than the SS  cable but they both were magnetic.



No idea why but I wold imagine the different grades have more or less nickel 

and chromium ?

Stainless Steel

The term for grades of steel that contain more than 10% chromium, with or without other alloying elements. Stainless steel resists corrosion, maintains its strength at high temperatures, and is easily maintained. For these reasons, it is used widely in items such as automotive and food processing products, as well as medical and health equipment. The most common grades of stainless steel are:



TYPE 304

The most commonly specified austenitic (chromium-nickel stainless class) stainless steel, accounting for more than half of the stainless steel produced in the world. This grade withstands ordinary corrosion in architecture, is durable in typical food processing environments, and resists most chemicals. Type 304 is available in virtually all product forms and finishes.

  

TYPE 316 

Austenitic (chromium-nickel stainless class) stainless steel containing 2%-3% molybdenum (whereas 304 has none). The inclusion of molybdenum gives 316 greater resistance to various forms of deterioration.

  

TYPE 409

Ferritic (plain chromium stainless category) stainless steel suitable for high temperatures. This grade has the lowest chromium content of all stainless steels and thus is the least expensive.

  

TYPE 410 

The most widely used martensitic (plain chromium stainless class with exceptional strength) stainless steel, featuring the high level of strength conferred by the martensitic. It is a low-cost, heat-treatable grade suitable for non-severe corrosion applications.

  

TYPE 430 

The most widely used ferritic (plain chromium stainless category) stainless steel, offering general-purpose corrosion resistance, often in decorative applications.

Thanks Richard,



Most of my experience with Stainless Steel has been in the dental office and 

observing the various forms and their relative corrosion resistance in the 

sterilization process  -  mostly autoclaving - which can present a quite 

hostile environment.  The bulk strength instruments like extraction forceps 

are quite corrosion resistant, but will eventually deform on their working 

surfaces.  The instruments that require sharpening will corrode quite 

readily, usually a black pitting will form on the surface.



I suppose there is an inverse relationship between corrosion resistance and 

strength and correspondingly a direct relationship between magnetic 

attraction and strength.
