 Sorry to butt in again C but you say that ACS don't have a matching wall thickness spindle.

 They have exactly the same C I gave you the part number.

 Cheers C

 If we are referring to the bending spindle problem only C I believe this

 is easy to solve.

 Aircraft Spruce offers a few tubes with the same diameter and material

 as the original spindle C with various wall thicknesses.

 Have a look at:

 http://www.aircraftspruce.com/catalog/mepages/4130tubing_un1.php

 Most likely you can insert a matching tube inside the original spindle

 to make it stronger.

 The inner tube can be fixed inside the original spindle by the roll pin C

 but of course some redux between the two tubes would make it even stronger.

 You can go further than that: As I was looking for a way to increase the

 length of the nose wheel assembly C to accomodate for a larger prop C I

 got the idea from Karl Heindle to increase the length of the spindle and

 to insert a nylon block between the friction disk and wheel fork. Alas C

 ACS has no tubes with a wall thickness similar to the original spindle C

 but there are tubes with sizes that allow them to fit into each other C

 and by doing so C you can create any wall thickness you want. It is easy

 to make a spindle that is stronger than the original spindle C and also

 larger if that is what you want.

 Karl is flying from his rough gras strip for years now with a 2" larger

 nose wheel spindle. I'm working on the same modification. If anyone is

 interested C I have quite some left of the nylon rod that fills up the

 gap between the wheel fork and friction disk.
