 Jim: I sharpen my chisel blade with a whetstone (also my single edge razor blades). Over time, this does slightly round the corners. To remove unwanted details from styrene castings, I take a little off at a time. When I think I am down to the bottom, I use the blade (vertically to the surface) to scrape where the edges were, assuring that I have removed it all and that no edge will show up after painting. BTW: If the part I am working on is already painted, so much the better. When My scraping removes paint from outside the edge, I know I am finished. You can finish up with fine grade sandpaper if you like, but scraping usually yields a smoother surface.
The key word is patience. I have been in the hobby for 77 years, and I still make mistakes, mostly because I get in a hurry.

 This is aimed at Jim Nichols and anyone else with experience in removing molded in features from plastic rolling stock.  I am considering attempting to remove a raised rivet strip (3 wide) from the sides of a passenger car.  Jim, I know you have addressed this type of operation previously and if my recollections are correct, perhaps suggested a chisel type blade such as the xacto 17 or 18 for this type work.  My fears are leaving deep gouges in the sides which I would of course, like to be completely smooth when all is said and done.  This would be on an O gauge car, so there is a good mm of material that would need to be removed.  Should I approach the job as taking it down in small layers until I reach the level of the sides or start in at the base (side level) and try to stay aligned as I work in from both sides.All thoughts and suggestions will be greatly appreciated.Jim Cochran________________________________________
