...any length nose gear, and any thickness can be purchased easily and readily.
I wouldn't even try to bend the double circle that makes the spring action.
If you want to bend thick wire gear, bigger than 1/8" to make some replacement
or In my case, longer main gear....bent at 90 degrees
you must heat it.
The wire I bent crystallized and broke when I bent it 90 degrees. You can hear
the sound of the crackling metal. Ferrous metals cannot be bent 90 degrees
without heating it....plain and simple.
Like I stated before....
if you were to get it bent, it would be very, very weak.
The wire I used was purchased at the hobby store, its purpose was for landing gear
wire. It cannot be bent at sharp angles without heating it cherry red, like any other
ferrous metal that you would desire to bend. When it cools, it is quite strong. Try to
bend , by hand, the bend you just made after it cools....
you can't.
