دليل محاذاة الزعنفة

Slid this over my 2.2" booster and the fins lined up straight on the first try, no eyeballing or re-gluing. The 1/8" slots hold the fins snug while the epoxy sets. Way less fuss than the cardboard jig I hacked together last time.

The alignment guide for my 1.63” kit with 1/8” fins slides right down the booster and holds each fin perfectly vertical while the glue sets. I checked with a square after and didn’t have to sand a single edge down.

My last build had fins so crooked they looked like a pinwheel, so this guide was a lifesaver. The 1.63 size slid down the booster and held those 1/8-inch fins perfectly straight while the glue set.
