Well, the railings are off of my Peter Strasser, and my fingers are on the mend! I've discovered a trick to avoid having to use ye olde razor saw to do a waterline diorama. This is an alternate method to the mix, paint and pour routine required for epoxy water.
Go to an art supply store and buy a pack of artists canvases, the ones with the wood frames behind them. Use a good x-acto to cut the basic shape of the hull out in the position you wish to have it, then paint the canvas the appropriate color for the setting of your diorama. With your gell or guesso, work in your major swells, then the waves useing what ever technique works best for you. I will be useing the crumpled aluminum foil method myself.
Work the model into the opening before the "water" sets up to the approximate depth of the waterline, then do paint touch ups and work the "water" in around the hull, add bow and stern waves, the wake, and any effects such as shell splashes, torpedoe wakes, ships boat's wakes and splashes from crashed aircraft.
Place a final wet coat on the "water" to blend everything. Also, if you leave a 1/4 inch border around the edge of the canvas, and you can use a reversed painting or picture frame from the same art supply store for the diorama border.
