Carded BANDITO Build Part 1 Fins

I recently released a new carded model PDF for a downsized Centuri BANDITO. The big Bandito design feature were the wedge fins.
This build does require some extra care, especially when forming the wedge fins.

Patreon members can email me at: oddlrockets@bellsouth.net and ask for the Bandito PDF.
Make two prints of the PDF, one on 20 or 24 lb. paper for the body wrap. 24 lb. paper will look better.
You'll need a BT-5,  just under 8.6” long. The printed body wrap goes over that.
The second print is 110 lb. cardstock for the fins. There are plenty strong when made from 110 lb. stock.
The Nose Cone is a Semroc BC-522P, 2.14” tall. This is the closest profile available for the downscale.

The fins are printed out on 110 lb. white cardstock.
Don't cut them out yet! You'll need to score them first.
BE SURE YOUR HANDS ARE CLEAN BEFORE ANY FOLDING!

I'm using the rounded metal back side of a single edge razor blade to score a line down the dashed centerline. Put a few layers of masking tape over the sharp edge (now facing up) so you won't cut yourself.
I'm not cutting halfway through the cardstock to make the fold. The backside (not sharp side) of the blade is pressed into the cardstock, embossing a line for an smooth rounded fold.
Carefully place your straitedge down the center before using the blade back.
Score all three fin centers before cutting them out.



After scoring the centerline:
Cut the fins out oversize, outside the border lines.
It's easier to fold the fins with some extra card stock outside the sharp tips.

Don't fold a sharp crease yet.
Using just your fingertips lightly fold down the scored line making sure your fold is centered.
The sharp fold comes in the next post.
