After five styrene bridges were complete unpainted I felt a curved timber trestle on a 2% grade would probably be the greatest challenge but turned out to be the funnest.

I could not believe it took $67 of styrene but it kept soaking it up.

You are young and life is long and there is time to kill today.
That would be David Gilmour
I like that guy

Would you look at that time here, I'm at the hotel but I need to hit the rack.

Hey TF,
I like David Gilmour too! He makes playing the guitar spectacturaly look so easy!
Thanks for the video.
Dave
I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
I'm glad you enjoyed that Dave, He's really something. One of the few guitarists in the world that slides his strings while playing.
The Trestle is a 2% grade. 18 in long in N scale is 240 ft. Compounded by an 18 inch radius which is basically equivalent to a 33 inch radius for HO.
Here is where the bridge will be placed
Hi TF,
I am eager to see your work as it progresses.
I know Dave but I ain't going to fast because this crap wasn't very easy.
A 2% grade compounded by an 18 inch radius confused me from the start.
I will probably have a hard enough time explaining it than I did doing it.
Normally when you have a straight flat bridge, you just set the Jig for duplicates and go.
A 2% grade in 18 inches is a 3/8" rise. Divided by the number of bents I used was 1/48 of an inch progression per bent. I do not have a scale that measures that and especially 4 times per bent.
We can jump ahead a bit so we all can understand measurements of four times a bent in 1/48th
Four measurements per bent 1/48th per parallel member, ....Yikes, I don't think so and that is not how I did it.
Every single bent progresses and every one is different is why they are numbered.
Let's take a little break here and I'll catch up with you guys tomorrow.
If you don't mind I'll just continue that Floyd where we left off. No video this time because you cannot improve on the old Floyd

Much easier to build them all the same but leave off or adjust the diagonal bracing on the bottom and just make the cuts when you get back to the accual layout, info for the next time you build a wood trestle as the bottoms were just buried in the dirt anyway.
I had all the wood to build it, but as easy as the dowels snapped made me nervous. I dont know what I did mathematically now but actually I remember now it was 1/45th
Yep!
It was 3/8 ÷ 17
So a long graph was drawn 17@ 2 3/4th
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
Man, Imgur is slower than molasses in January today so you're going to have to bear with me. I'm feeling a bit foggy today
Check out those microlines of progression, I would hate to have to measure that 68 times.
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.
I don't watch much TV but Happy Days is on and it looks like a good one.
I'll be back after I hang out with the Fonze for half hour
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 done
Some distinctive flavor in a sandwich is styrene particles with pepper you know
I'll make an extra one for J.R.
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 those
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.
When spending a love of passion losing track of time on a project, it is always so rewarding when something starts to come together.
When it starts to look like something.

VERY Impressive, TF!

What Ed said!!
There are modelers. Average modelers. Good modelers. Really good modelers. Above the normal modelers. Exceptional modelers. It is here we find TF.
