I'm New, Please Be Gentle
Hello every one.
I am new to Garden Rail Road and G Scale Central.

I am looking for any information or follow up on a post by (Moonraker about his Brunel wooden trestle viaduct)
The last post about it was from 2010.
My wife would like me to build one on our RR. ;)
When I did a search I got 2 links back to the same post Moonraker started.

Thank you for any help with this.

Welcome -can't help you directly, but I'm sure some of the clever blokes on here can! Best of luck!
 
Welcome. Is this what you are looking for ?

With regards to old posts there have been a couple of software upgrades here in the meantime that may have caused the loss of some posts and picture content. You could try a PM to the member, he is still listed.

I`m still here and my Brunel viaduct is still standing. I find that I have to recoat the woodwork with an external varnish every couple of years but no other problems.

I made a mould for the piers in chipboard and cast them in situ using readymix concrete from the local hardware store. While the concrete was still wet, I inserted two threaded vertical stainless steel rods. It is these rods which actually carry the track bed; the wooden frames are purely cosmetic. I painted the rods matt black so that they are less visible.

The trackbed was made from a builder`s wall board (can`t remember the name) which was drilled to accept the threaded rods. Nuts then set the trackbed to the correct height at each pier.

Templates where drawn out for the outer and inner frames. Stripwood from the local hardware store was then PVA glued and pinned to fabricate each frame. Each set of four frames was then fixed in place with horizontal struts which were bolted to the frames.

A photo is attached. Note that I spaced the piers too far apart.

Thank You for the reply's.

Thank You for replying.
I have a few questions on your build.

Could you tell me the angle the bents are at or should be?
How far apart do you think the piers should be spaced?
Also if you have a link to any other pictures.

I will start a thread on our build when my son helps me learn how to post pictures.
Thank You again.

If you are thinking of building a wooden viaduct I think you will need all the support you can get.....

Sorry!!!!!!!!!!!!!!!!!!!!!!!!! ;) :D ;D ;D
 
I built a small Timber Trestle Viaduct in my old line in Luton. Twas more based on an American theme, however the basics of construction are pretty similar, particularly the actual bents. For these you will need to make yourself a Jig. Nothing fancy just something to hold the Bent uprights in place to ensure that all the bents come out the same. I made my Jig with a piece of good flat ply, but some Melamine will work just as well. So long as it is good and flat with no twists. I used the same kind of Square Timber for the Jig bents holding part as I used for the bents themselves, though slightly smaller does work better. Of course you will need to use timber each side of your bent uprights to hold them in place. Wish I still had my old jig to show you with a pic, but I passed it on to a friend who will be making a Trestle as they call them over the pond.

When you build up the Bents with cross pieces, do not rely on only glue. Use pins as well, some even use BA Nuts and Bolts which is better but can work out to be horribly expensive. For your pins, drill slightly smaller holes ALL THE WAY THROUGH as if you bang them in the wood will split. Also use Steel Pins as brass ones tend to work themselves out over time. You could let your steel pins rust a little then give them a bit of WD40 in to slow or arrest the process.
Hope this helps a bit.

Sorry for not posting any up dates.
I have been busy with our build.
After 110 bents and a lot of other work we had trains running for over an hour last Saturday.
We hosted our local Garden RR Club and not 1 miss hap till after the meeting.
A leaf fell on the track and unhooked the last 3 cars.
Now to start making buildings for the winter.
21% this morning.

Wow ! Nicely done.
 
Good luck mate,
Hope to see how your endeavours pan out.
May take time but will be well worth the effort.

Have a number of bridges to construct for Apache Junction, and an old style trestle bridge will be something I am looking forward to building myself.
Will about 9 or so foot long. No where near as high as I would really like it to be but can only do what is possible,

:) Have to say you have done a superb job with the bridge Peter, but just one small comment please.

Will you please refrain from posting pictures of that beautiful Pannier Tank engine of yours.
Makes me very envious every time I see it. :mad: :inlove::clap:
