Sorry it took another day to get to this. Had to get the Christmas decorations taken down outdoors on our warm day we had here yesterday. Now, my updates....Before painting, I used a light coat of drywall joint compound on mostly all of the base of the plywood. This sealed the seams for the plywood and screw holes. It also makes it easier to apply the paint and prevents epoxy from leaking between the sheets of plywood. Don't forget to sand it smooth before painting.
First, I painted the base with Woodland Scenics variety of water colors. Tan on the riverbanks, to some green, then light blue, then the main body of water as dark blue....blending together as I went. I really like the dark blue Woodland Scenic made for the illusion of depth. It is not black, but a very dark blue. Only took two and a half bottles of the Dark Blue for this area. About a half a bottle for each of the other colors.
Next I added some stone walls to complete the sides...Then, I poured my coats of bar top epoxy (Glaze Coat Clear Gloss Oil-Based Lacquer - High Gloss Finish). I did about a 1/3 of a section at a time (which was about a 1/3 of a gallon, too), so I could spread evenly and heat gun the air bubbles out. Then, mix another 1/3 of a gallon and so on. After about 4 hours, add your second coat if you would like. After you've added all the coats, let dry for at least 24 hours. ...Don't forget to tape up your ends to keep epoxy from spilling onto the floors! :-)
Next I added the waves using Woodland Scenics Water Ripples. I used the ripples instead of the Woodland Scenic Waves, because of the scale of this river basin. I can use the Woodland Scenic Waves for the tug boats as they part the water. Additionally, as I worked with the ripples, I sprayed with some alcohol to help level and smooth them out a bit more. It took about 4 bottles of Water Ripples to cover the entire area with waves. Furthermore, I left about 1/2 an inch or so between waves in order to keep some of the reflecting principles of the epoxy. If it had all been solid waves throughout the base, I feel I would have lost some of the reflectivity. Besides, you can always go back and add more waves to get the effect you desire. It's difficult to take them back if you add too much.
Next came wiring and the bridges being added. I wanted to showcase as many of the Lionel bridges that I could (and Lionel lighthouses) in this river area. I still have a girder bridge to add, but this gives you the idea. I've also added the interactive buttons on the side of the train board (lower left in picture) for the kids/adults to blast the foghorns of the lighthouses.
One last picture with bridges up!
Now, after months of stressing about this river piece and how to make realistic looking water, I can finally begin to lay more track and not be as stressed out about something I knew very little about, which was trying to make realistic looking water!! Hope this post helps somebody else down the road with their river project!!
