Large Scale Central

Building a 'shad-belly' truss bridge

Track and Trestles
#1

The wood is Ipe’ (Brazilian Mahogany) and should hold up perfectly outdoors. fingers crossed

#2

Dave, that looks right nice so far. Looking forward to the rest of the build.

#3

Very nice.
So this means construction on the outdoor layout is moving forward :wink:
It looks like it will be one fine looking bridge when you’re finished :slight_smile:

All belly and no backbone? Interesting concept.

nice looking bridge, David… :slight_smile:

#7

Anyone have a source for some small bolts and nuts? Square head preferred.

#8

Going by the name I’d be inclined: this bridge really groans when it’s under pressure. :lol: :lol:

Lone Star Bridge and Abutment uses mahogany for their trestles and bridges, so it should hold up fine. If you just need castings of nut and washers, Ozark Miniatures sells them, both in round washers and square ones. Or if you need real ones, I used some metal rods and threaded the ends for 4-40 sized nuts on my 2 Truss bridges.

Nice bridge ! :slight_smile:

The Ozark details will work great to ‘bolt’ the posts and braces to the lower cord.

Any suggestions for details from the Fine Scale builders?

We don't need no stinkin' guard rails!

No guard rails were used on any bridges or trestles in the 1860’s.

#16

Maybe the track laid on a deck on top of the bridge would be better. ???

I like it both ways. The advantage of a deck bridge Vs. a Through Truss is that there are no clearance issues to worry about, so whatever you decide to run in the future will fit.

#18

Though it takes up more room that way, it does look better…:wink:
