Elev. Pull pull Question

[Rcmaster199 at aol.com]

I used to use all-thread until I got bit.  I'll stick to 2" to 4"  bolts as I 
have been doing.

Don’t remember the  source, but someone specifically recommended the mild 
steel in the  all-thread in favor of the hardened (more brittle) steel of a 6-32 
socket  head screw -  and the idea was to have a horn that may flex a bit  
without fatiguing and breaking, as harder, more rigid materials can.   
I can’t quote  metallurgy on this one – all I know is that the mild steel 
all-thread into  dowels set into square balsa blocks set into the control 
surface has never  shown any problems…

Another option- buy 6-32 all thread at  local hardware store.
 
Cut stud lengths as needed and thread  into hard points with a bit of epoxy.
 
Ive been using them for years for  elevator, aileron, & rudder.
