Hi all, things have been moving slowly though the spar is now half completed.
Have been doing a lot of experimenting with urathane disc's for the landing gear suspension, I got the idea from this forum and on investigating found that the Chipmunk and the Mosquito used this method of supension.
I have tested many different types of urathane made here in Australia, but with not much success.
Some had suggested fibroflex in one of the threads I had read here, so
I pursued this company which I found in Germany, the have very comprehensive data on their products which turned out would have saved me a lot of time and expense if I had went to them first.
Any how we have successfully designed and tested a leg (as attached j-peg)
to give 135mm of travel under 1250kgs per leg.
This is sufficient for a 950 kg aircraft to have up to a 3.5 g landing, (including tyre crush).
If your looking for urathane rubbers you cant go past Fibroflex

Have also put a picture of setting up the outer wing spar jig just for interest.
