You're welcome. Looks like you have the hang of it! Thanks very much for sharing.

I would love to see some of the construction photos and a little bit of the how-to on this bridge project. I also ventured into a suspension-type bridge, but my techniques were much more primitive than yours. I'm interested in how you threaded the cables in this unique O-gauge creation.

Cheers,

John

Double Track




Photobucket



This is an end view of a upright support. I've routed two groves, one for a wire and the other to hold the sections with holes to string the cables thru.





These are paper cutouts of the X supports




This is the bottom of the roadbed. I routed a 1/4" x 1/4" grove on each side to hide the cable, It should have been deeper.

This is the top side of the roadbed showing holes drilled for the cable, 1 1/2" apart. The wider space showing is for the upright support.

I came up with this method to hold the roll of weed eater twine

Here I've strung the first strand of cable, just kept threading it back and forth, aprox 40 ft. of cable.

Cable threaded before tighting



This is what I used to hold the cable in place and tight. A small cable crimp end, turnbuckle and a cup hook

Each section takes about an hour to string.

The total length is about 8 ft. I started out with a 1" x 8" x 8' and the supports are 27" tall.

I'd be happy to answer any questions anyone has.

Thanks for looking,

This is a facing I'm making to go along side the roadbed to hide the exposed cables that show from the bottom.

The two pictures are the same piece, just flipped, I'm trying to decide which way to put it.

Looking good Doug. Can't wait to see what it looks like with the facings on the sides...

Thanks for sharing.

This is where the bridge will be placed, joining the double helix at the bottom.

This should win a prize in creativity. With the 2 helixes, it gives an art-deco flavor

Just an update on this project, It hasn't died, it's just on the back burner of the list of honey-do's
until I get the house sold in Fla. and move this to my basement in Culpeper.
