Photo-Etch Calculator — PE Detail Set Planning

Use thin CA (cyanoacrylate/superglue) for most PE parts. It bonds metal to plastic instantly. Apply a tiny amount with a fine applicator or toothpick. Avoid poly cement — it does not work on metal. For large PE panels, consider slow-setting CA for repositioning time.

Use a dedicated PE bending tool (like The Hold and Fold or a Trumpeter PE bender). For simple bends, use two flat-nosed pliers. Always bend along etched fold lines. Practice on spare PE before working on critical parts.

Yes. Metal PE parts need an etch primer or at least a light coat of metal primer to ensure paint adhesion. Standard plastic primers may not grip bare metal well. Spray a light coat of etch primer on the fret before removing parts.

A typical 50-part PE set adds 4-8 hours to a build. Complex sets with folded parts and intricate assemblies can add much more. Budget 3-5 minutes per small part and 8-15 minutes per complex folded part.
