many thks u mate so hw did u use the beam?? cut with? hw? saw? or ?
 
Steven - I have a table saw which is very useful for ripping down timber, so I don't always use scrap, particulary if I want long lengths (most pallets only yield just under 4ft). Angled cuts I use a chop saw.

The material I use is very basic, I have only myself to please, and a wallet to protect:rolf:

The wooden bridges and "trestles" are nailed using an air nailer. I bought a compressor from Aldi 10 years ago and it has been a great piece of kit. I also have a small electric nailer as well.

A good handsaw is useful tool if there isn't much to - you need small teeth for cross-cutting and large teeth for ripping along the grain of the timber.

You can make a very simple jig for cutting square or angles - a piece of strong flat plywood, two nice piece of timber screwed to it to form a channel to hold the timber to be cut and then very carefully cut the angle you require through those two pieces and you've got a guide. Obviously you need to make sure the screws are in the right place - one at either end of the timber guides with one either side of your intended cut.
 
In North America there's a tendency to call anything a trestle that isn't an arch or a suspension bridge. Originally that seems to have applied only to timber bridges, but steel bridges - even long plate girders - are often loosely called trestles. The sketch in the opening post would be probably be described as a deck truss or an underslung truss by an engineer. The Bridge Basics web page is excellent, and gives the proper names for the specific types - it should be very helpful for modellers.

I was delighted to see the model based on the Connel Ferry Bridge - it has long been one of my favourites, and I always try to get a glimpse of it from the train on my trips to Oban (and just possibly, in the distant future, it may be a GME project).
