Like I said, I should have taken a photo; big dummy.  Now I can't remember the name of it.  It seemed that was all Lowes was selling except for the white bead stuff that isn't as useful around the layout.  Has anyone seen this?

Think Lowes has some that is made to pass air thru. It is not a smooth surface like the standard pink and blue foam sheets.

Art....this is one of the most beautiful model bridges I have ever seen....it sure puts my bridge project to shame!!  You are doing everything just right and when completed this will be a masterpiece...heck it already is.  I am enjoying this build and look forward to more progress...thanks so much for inspiring others here on the forum!

You have a wonderful project in progress, Art.  Just a caution.  I was working some foam board for one the Fort Pitt Highrailer modules, and did some model paint touch-up of the back side of some foam pieces. The foam and paint didn't do well together, the paint ate the foam.   Different adhesives also have foam problems, which I think has been mentioned.   Mike

I see that you have been getting a lot done too.  I have an additional reason as I'm having the gang over Sunday.  Which reminds me that I haven't heard back you so I'm wondering if you got my message?

Alan - Thank you, a complement from a master like you is very much appreciated.  I just saw your new bridge installed and it is magnificent.  When is the staff going to venture west and visit us Midwesterners?  Will you be at TrainFest this year?  I will get the red carpet ready to roll out.

Here is a picture of the foam that I am using.

I have used water based latex paints and I hope that they will not attack the foam. 

 

The glue decision is still up in the air.  I tried a little of the construction adhesive specially made for foam and felt it was hard to work with.  I have a sample glued with plain old Elmer's white glue to see how it works.  It was much easier to work with.  And I am considering the latex caulk suggestion too.

The next day she went with me and we spent another hour looking at every paint sample in HD.  We finally picked out a light base color and two accent colors.  Got home, painted it on the foam and she said it wasn't right yet.

 

So my son-in-law is a contractor, carpenter, and master faux painter.  I asked him if he could stop over on the way home and help me.  He looked at all my colors and started painting and blending colors and it started looking like limestone to me.

 

Armed with my new confidence I forged ahead and tried his technics.

 Be very careful selecting paint colors in stores.  The color you see is the color as it appears under their type of lighting.  If you have incandescent spotlights and they have fluorescent lamps; the colors won't match. Even fluorescent lamps are differnt colors that will affect the appearance of your layout.

Art,

Thanks for the photo.  Your bridge is great!

Beautiful work! I was reminded of a project my son and I worked on for school when he was in 7th grade. We made a O gauge section of the Rockville bridge in Harrisburg PA. I let him do the stone carving with a pencil point soldering iron. It turned out really nice, and is kept in the workshop as part of the staging yard fro our suspended layout.

Decided it was time for an update.  Actually it's past time, but anyway...

 

I have finished the under arches and have just completed the second section across the front.  Here are a few pictures of fitting, gluing, and clamping the second front section.

21315C

21315D

 

After letting it dry overnight, this is what it looks like so far.

21415B

21415C

21415D

21415E

21415F

 

I think one more panel will finish the front and then to the backside where I have had a few problems.  But I think I can salvage most of a panel.  Time will tell.

Man oh man, that is B-E-A-U-T-I-F-U-L. Some real talent out on this forum. Boy do I wish it was contagious!

Is is contagious.  Most of the stuff I have done I would have never thought to try on my own.  But after I read these forum posts, I give them a try.  My talents are not nearly as good as some of these folks... but you get better every time you try it.

Very nice bridge, and a great way to highlight the curve on the layout. This forum does a lot to inspire others to try new projects and techniques. We never know what we're capable of until we try.
