Hi All,
As a new member I'm not sure if I have got the hang of adding photos correctly, but if it has worked this is a shot of a MVL bridge that I took delivery of early last year.
Initially I painted it with an acid etch primer from a well known car store (won't mention names for obvious reasons) however this paint started cracking and blistering within a week and the only way I could finally remove it satisfactorily was to have it grit blasted.
The photo shows the bridge reinstated after blasting and I think that the finish looks quite good and even now after about 9 months I can't see any signs of corrosion on the aluminium, so I think that I will leave it as it is.

Well that's strange. I clicked on the link to your photo just now and ping! .........up it came. Just tried to go back to it and the link didn't work the second time.
Anyway, nice bridge, and I like your raised trackbed structure with the short lengths of cut timber as cross members.

Actually they aren't timber, its recycled plastic from Filcris (no connection apart from being a satisfied customer) I've seen too many exterior structures made from wood, including so called marine ply rot in no time at all. So this time I decided to make sure it would outlast me, sure it is more expensive than timber but at least I know that it will last and I have no maintenance to carry out on it.
I decided to use cross "timbers" to help with water run off and it does also allow easy construction of any radius of curve, the only downside is a lot of cutting involved and a lot of screws used.

Look on pages 22 and 23 of Nov. 2014 SMT where I've use Filcris. The ladders system under the track in photo 7 is a similar set up but I've dispensed with the cross members and secured my track to the frame. The vertical supports on my set up are shorter and set into concrete in the ground.
