Gidday,

I have started to research the option of protecting my tailspring and the tailwheel forks as my build progresses. A recent pow wow with 3 builders concluded something was required such that the process did not expose the job to temperatures above the tempering temperature of the tail spring. Now I'm ignorant of all this stuff, so didn't really participate, only listened. A conclusion was made that powder coating might be an answer but my recent enquiries lends me to have concerns that the flex of the leg could encourage departure of the surface. i.e. cracking.

An old Europa builder I knew used Electroless Nickel. No clue if this is the best, but I do know that he would have researched very thoroughly. So, I'm interested in what opinions the forum might have of this method, or other suggestions. My parts definitely need sandblasting to remove surface corrosion at any case.

Tony...I have no expertise to lend to this discussion...without a  

great deal of thought, I powder coated my tailspring along w/ all the  

other ferrous components and fittings.  Ms. E is not yet airworthy, so  

I have no experience as to whether or not the tailspring's flexing  

will cause cracking of the powder coating.

Tony,



I would be very careful with plating processes as the spring is very hard and the process could induce Hydrogen Embrittlement into the surface. The result of this could be cracking and breaking of the spring.



If the spring is a decent spring steel it will have a hardness of at least 45HRC which would make it succeptible to cracking.



Best regards
