well keep up to date on the build. I plan on getting a few more bents done today.
Nice!

I know that I made a slight mistake by not priming and painting these ones but I have a steady hand ;D ;D ;D
Looks good to me. Looking forward to this build.

Rusty........
Great build. Regarding the NBW castings. Find a drill that is very close to what the pin on the casting is made to. Then snip the castings off of the spru with a dull, not Xuron.. and that flattened out end will help hold them in. Then blast the finished bent with dull cote. That will be enough binder to hold the casting into the wood.
see ya

thanks bob. that is why I like the site. I would not have thought that. thanks for the tip
Hey Rusty, I have found that if you hit the bolts with a dull coat finish after your done the color of the bolt isn't far off from a rusty one. I normally just add streak marks.

Castings came in today. Time to get to work....
Very nice job Rusty...love the look of the wood! ;D
update not much done but still moving along. I changed my mind on what I wanted. I wad going to use this for going on a small rocky gorge. but sine then I have decided to make it going over a road. this is where I am at for now. two more of the small bents for over the road then finish the castings. I hope to start putting it all together in the next week or so,.

You'll go insane drilling those holes! You may want to keep it here but If you want to get rid of the fuzz on the wood, a quick (and I mean quick :o) pass over a small flame will remove them. And yes I do have a fire extinguisher on my workbench!
Looking good!! I'll put in an order for a couple dozen...any size I'll make'm fit...Heheheheh ;D ;D ;D
I built this little trestle using the holding jig that I made on my Bridgeport using aluminum. The vertical cuts are for the cross-pieces and they are undercut so the round pieces of wood will fit on top of them. The little holes are used for pushing out the trestle, once everything is glued together.
The trestle in the photo goes nowhere. The track on the other side of each portal goes only a couple of inches
The jig did not appear in my last post. So let's try again
Bob...
To attempt to answer your question......... I will lean to my greater experience in the west........
I'm first reminded of my dad who worked for the Burlington....... "The railroad calls everything a bridge! It can be a culvert to move water from one side of the right of way to another with nothing more than gravel fill........ it's a bridge".
With that.... I would suppose the answer to round or squared is a function of available materials and how fast they wanted to put it up. If the line was to be a short lived logging spur that would be pulled up and moved, there was little or no treated wood and was generally constructed of available local timber as they cleared for a passage way.
By the 1950's, with larger earth moving equipment available, by guess there were more land fill bridges than wooden trestle but again that might be a local thing. In the west it was not uncommon for the various railroads to run out hoppers and dump dirt and rock over the sides of the existing trestles and slowly fill them in; leaving the wood structure there now encapsulated in dirt and rock. Finally they would come back and set the final grade a bit above the original trestle filling with ballast and conventionally spaced ties. Some historical books show such filling projects.
Finally........ to answer your question....... there is a prototype for everything so what looks good to you? What sorts of timber is or was available in the area you are modeling? Otta be a start there somewhere ! ! !
see ya
Bob
Well done Rusty!
