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 Laugh

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.

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

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.

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.

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.

Hi TF,

I am eager to see your work as it progresses.

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

You are young and life is long and there is time to kill today.

 

That would be David Gilmour

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

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.
