Tip of the Month: Perfect trim

Perfect trim
The most enjoyable part of attending model shows is getting to meet readers who have some great tips to share.

At this year’s NNL East, we ran into Griff King, who described his favorite method of creating molding around scratchbuilt window openings. As he outlined the technique, he sketched it to give us an idea of what this scribing tool looked like; it couldn’t be simpler.  

Cut out the desired opening, then assemble the tool by sharpening one end of a short (an inch or so) brass rod no less than 1/16 inch in diameter (a thinner rod with less strength doesn’t work as well). Lay another, longer brass rod next to the pointed piece and solder them together. Slip the two-rod unit into a larger piece of round or square tubing, and crimp the opening to squeeze in against the “cutter” and keep it in place.

Determine how wide the molding will be, and bend the long rod away from the sharpened piece so that the space between the rod and the point is the width of the desired molding.

To use the tool, place the long rod in the window opening so the point lies against the plastic, then pull the tool the cutter around the window opening. Keep steady pressure on the guide bar and proceed gently around the window for the first few passes or until you get a defined groove around the window. Clean up the groove with a small file if necessary, then paint or foil the new molding.

Thanks for the great tip, Griff, and we’ll see you at the next NNL East!
