Here are the pictures of the finished tail wheel. I removed the tyre from the wheel when soldering on the washers, probably not necessary - but just in case, I still consider myself to be a novice solderer, generally happy with the result though.

Bending the wire tightly enough around the collar (and square to the tail wheel portion) was quite a challenge but also with a tweak here and there got it pretty muuch spot on. Even with the 90 degrees bend as tightly as I could make It I still needed to add a piece of ply under the fuselage to provide enough clearance for the tiller. This still needs to be shaped to blend in with the fuselage.

The fuel tubing method was easy to do and is completly effective.

Is it advisable/necessary to insert the fixing screw into a hard wood block in the rudder. As it stands I have just screwed it into the balsa and hardened the threads with CA.
