Subject: Pietenpol-List: 4130 Question

Tried to order some 22 gauge (.030) 4130 to make my rudder/elevator/aileron 
horns today and can't find any (checked AS, Wicks and Shapio). Thinest I can 
find is .040. Has anyone tried making these horns out of this thicker material?

Can anyone suggest alternatives? Bernie didn't use 4130 in the early days did 
he?

They also said that normalized 4130 is impossible to find, and most is all 
anealed. Does this make a difference to us Piet builders?

Looks like there was some delay in getting the article on the
photoshare. My apologies. 

I had a look a few minutes ago and it's there now.

The plans I have say the hinges etc have been replaced by cast
aluminum.  I designed and built bolt-together 6061 T-6 aluminum pieces
that far exceed the min strength required, and take a couple of evenings
to make out of flat and angle stock.  Haven't done up proper set of
drawings, but have plenty of digital photos if you'd like.
