This is gonna be a fun little project, and I remain confident, I will be able to turn it into more work than necessary. It is based on a picture by Mike Condren, here is a link to his website and photo of the car. http://condrenrails.com/Frisco Catalog/MOW-water-cars.htm Now, at first glace as suggested I needed a Tichy #4025 tank car kit, but if you look at the Tichy car it has an extra row of horizontal rivets towards the top of the car, so that car was out plus it looked a bit big, ended up robbing a large dome from a Tichy kit, and settled on a Proto 8000 gal tank car for the project it had the right pin lifters and a few other details as well. Bad thing is, the insides of the tank were flat and not rounded which is where the "more work than necessary" part started. I was lucky enough to chuck the whole car in my Sherline mill, and just milled the part of the tank off that needed removed, that was fairly easy, but when I was done with that the walls of the tank where it was milled were about 9 scale inches thick, well that wasn't gonna work. So I went to work on that with a round sanding tool chucked up in a dremem tool, about 5 seconds later, the drum plugged up with melted plastic. Glad I have 3-4 of them, but figured I would try the Tamiya drill, that Keith Robinson turned me onto some time ago. It turns slow enough not to melt the plastic, and after a fashion, had the part of the tank I needed round, basically round, or as good as it is gonna get. Then the rivets were ground off the top where the bigger dome would be, attached the larger dome, then used .005 X .060 Styrene strip bent anround the dome for the new rivets, and Archer rivet decals used. Not having any idea just how the inside of the cut away looks, I noticed the 55 gallon drums leaning onto the sides in the photo, so that gives me an idea of where the floor needs to be, I am gonna use a strip of Tichy grating for the floor that should be OK. Turns out the inside diameter of the car is just a bit smaller than a dremel cut off wheel. Ihad a slight used on handy so traced a piece of .040 Styrene for the plug in the tank, and will place a bung towards the bottom with some sort of gate valve in it. Still need to come up with that. Anyway here is a start on this project, will add pictures and text as we go along. Thanks for looking.
