Greg,
Thank you very much for these tips. One question: how do you attach the nails to the alu?
Cheers,
Peter.

I tried 2 methods. 1, was to just glue the nail in with a good blob of outdoor Liquid Nails.

This seemed a bit liable to wobble, so I tried using small plastic fittings from garden irrigation systems - I presume you have similar in NZ (or don`t you need to water plants?) I threaded the hole in Al, and ground down the nail to fit into the plastic fitting.

If doing it again, I`d consider using threaded steel rod instead of nails.
On a different track (ha!), have you considered just laying brass rails onto flat timber - no sleepers? I used this method on bridges where is wasn`t noticeable.
