Thanks for the vote of confidence Dave. 

This bridge has been a bit of a haul.  Maybe I can think of something this weekend and I wouldn't mind if anybody gave me a few idears either?

The pony truss can come up to the bottom of the stringers, that's not the problem.  Would you ever see the same wood stringers going across a truss bridge?  I could stagger them back and add on to them. 

What would look normal for the support?  I've been contemplating these two things for a while.

Hi TF,

I'm quite sure that you will be able to come up with a proper solution.

Thanks John

 

I kitbashed this double Warren bridge a couple years ago.

The original plan was going to be earth built up on the other side to transition to the timber trestle.

A discrepancy came about when I built my Viaduct Bridge last year.  I added a line coming off that bridge to go to the roundhouse service facility as it looked like it would work better.

So I had to carefully take the double apart, ...buy another Warren truss, modify the center to make it shorter and make this triple Warren

The discrepancy if you look to the left was, ...The dam pier was going to be in the way but now with the triple Warren the pier would fall short.

This opened a whole new can of worms because now the tripple Warren will have to connect directly to the timber trestle.  One succeeds one objective to lose the last.

Nice work!

Since it's in N Scale, it's even more impressive!

Good evening

My daughter walked me through some things with my phone last night and picture posting is working normal today.

 

I wanted to get the abutment adhered to the bridge for placement and so I made one.

Nice wiork, TF! I'm more a chop 'em off after making too long sort, but if you really want things to look right, there should be more of a plan than that. Very impressive!

TF, that is a great-looking trestle.

You have a real talent -- I wish I could do half as well.

I hope you continue to post photos -- I can use your photos as a guide if I decide to ever try something like this.

I don't know B.  Sometimes, it depends on which lines or lights you look at

I thank you for your kind compliment and a good question selector.

The top rail joists of the trestle were

Item number 155, 4 stringers per support as a rail base between bents.

4 @12 ×18 was usually the standard.

I had choice of 10x16 or 12x20 was the only choice, I took the 16's

For some reason laminating styrene gets thicker as it softens and expands while bonding.

First, let me compliment you on your fine work and your vision.  Very nicely done!

Did you happen to cut many straight stringers, or did you cut a curved path out of styrene?  I ask because you would not see a true radiused set of stringers atop a timber trestle, only nested stringers.

I see you have girts in there as well.  Nice to see such great detail. Cool

Finishing up the bridge ends that will descend into the hillside.

What would come after this became a tough part of the project.  You have to make the Ravine fit your bridge when the bridge is complete.

Before all that is the fact that glass never lies.  Right side up the bridge ends had weight to them and were dangling in the breeze.  The bridge ends had to be completed upside down taped to the glass table to stay true.

It was a little freaky finishing the bridge upside down but it was kinda fun.  With the exception of my dyslexia setting in a time or twoLaugh

Come to think of it I didn't have any drawings for this bridge either.  It would probably take longer to draw it than to build it.

I kinda winged it as I went along and really liked the Cosmetic effects of this bridge.  The angle bracing form diamonds instead of X's that I liked.

The bridge started to get fun adding the purlins and angle supports.

Also really cool how surdy it started to get even though styrene is just some flimsy material.

I was amazed how fast I started going through styrene and had to find more.

There are modelers.   Average modelers.  Good modelers.   Really good modelers.   Above the normal modelers.    Exceptional modelers.   It is here we find TF.  Bow

I think the railroads as powerful as they were had a deal with the lumber mills.  From what I understand they got their 12x18's 32' long to stagger them on the bridge bents.  

Go ask Menards or Home Depot if they have one of thoseLaugh

I wasn't going to be that fancy staggering the runners in N scale.  Maybe HO I would.

And then I learned about retention with styrene.  After the T pins were removed they lost their 18 inch radius into about a 20.

After trial and error I eventually pinned them into a 16" radius, took a hairdryer to them and stepped them up to form an18" radius.

I put the left over Ribs over water in the oven covered with foil.

We're going to make some 2" thick sandwiches so I need to find my Razor Saw.  I'll let you know when thier doneDinner

Some distinctive flavor in a sandwich is styrene particles with pepper you knowLaugh

I'll make an extra one for J.R.Dinner

So fast forward a bunch of hus fuss and styrene dope.

The bents were made.

I subtracted number 1 and number 11 because I rechecked my math.  I didn't take into consideration the thickness of the bents.  Cosmetically it will turn out better with two less.

Check out those microlines of progression, I would hate to have to measure that 68 times.

So I didnt have to measure 1/45 68 times the graph graduated 3/8 of an Inch across the poster board where a drywall square could be used to mark the horizontal placement per bent.

Just a chicken scratch on the leading timber so a square could be used later after I put them back in The Jig
