Following the progress of Jerry M. layout has inspired me to get back to some landscaping on my layout.
I would like to build several wooden tunnel portals. Can someone share some pictures, plans and dimensions that might work in our 0N30 world.
I had some plans but they are safely stored away ... somewhere ..

I like the products by Hunterline and they have a timber postal in "S" scale that will work for On30. http://www.hunterline.com/ scroll down the page

Hunterline makes a good product, however, I wish to scratch build.
I have the wood ... now some plans and a little work ...
Harold,
I like both portals. Do you have measurements on the style Jerry M. has built ....

Tom I like the hunter tunnels too..but I went with a fairly rugged looking wood resin casting from DR Bens. Neat looking no liner.

Tom, Here are some tunnel dimensions; You'll have to come up with your scale measurements.

If interested, you can build with this;

Into this. Just let me know and I can email you a pdf on building it.

I made up a card board mock-up of a Harold tunnel and one of a Louis tunnel:
The Harold tunnel us 4 1/4 inches high on the inside:

The Louis tunnel is 4 inches high on the inside:


This is the corner of my layout that I want the mountain with the tunnels:

The scene will be light logging and a hunting camp. Just a backwoods area ....

There will be a switch back going into the area as seen on the back right wall ..

Hi Tom, You might want to have a look at this portal for some design ideas. http://www.sceneryexpress.com/prodinfo.asp?number=FL6195
I love the look of this portal but like you want to scratch build mine. Over a year ago I drew out in CAD a basic design. My opening demensions are the same as Louis (desertdrover) the only difference is my overall width and height are 24'
After looking a his plans I might drop down to the 20' mark.
Good luck on the project

My original On30 tunnel was the S scale version of the one Scenic Express sells:

I replaced it with the Ohio River and Western version because the OR&W tunnel looked more narrow gaugish. I have never seen a proto portal like the Scenics Express, etc.

Tom, I used Harold's design for the liner and built a facia like Louis posted. It sure made a dandy tunnel portal! "X-4" !

Nice portals, Tom. And the switch in the foreground of the last picture looks very good too. Great track color.
