Today's project was a concrete viaduct bridge. I think I'll add some railings before I install it tomorrow.

Dave after you cut out your foam and before you paint it do you cover it with plaster/mud and sand it to get rid of any imperfections? Choo Choo Kenny
Ken,
I do not try to fix the imperfections. I do sand it pretty well. The first coat is heavy body acrylic, then an I/A wash then airbrush. There is a seam in the middle of the smaller arches but the bridge is going on the back side of the layout. I might have tried to fill that if this piece was slated for close-view.

Dave outstanding. Did you cut out the holes with Hot wire cutter or Blades?

Nice bridge. I also don't smooth and sand out all imperfections - not necessary, at least with many.
I've had good results using spackling paste to cover up and smooth out imperfects and rough foam surfaces. I like the stuff that goes on pink and dries white - easy to know when you can sand and paint. Cheap and easy to use.
I'm more likely to ADD imperfections than remove them. But, if you want a nice smooth surface, drywall compound works well.
nice Dave
Looks real good Dave!!!
FYI, John Sethian wrote an article in OGR run 245 about making foam viaducts. That is where I got the inspiration to build this one. He used hot wire to cut his. I used a hole saw and band saw.

Very nice.
The viaduct looks great! Thank you for the noted on finishing.
Nicely done!
Thanks for sharing.
Man you do some nice work! Now, which O gauge figures are you going to scarf up for this project?
