Lancaster Shrinker-Stretcher

Here's a new tool I got to help fit the canopy side skirts. It's a Lancaster Shrinker-Stretcher. I only needed the shrinker jaws and I special ordered them with a stippled finish which is the roughness of 180 grit sandpaper and much easier on aluminum than the serrated jaws. You put the edge of the metal you're trying to shrink in the jaws and squeeze with the handle.

It allows you to make a compound curve like the one below. It may be hard to see but the side skirt is bowed in both directions which makes it hug the fuselage nicely.
