Furshlugginer... A Scratch Build

Furshlugginer: - in Yiddish it means something that is old, battered, or junky.

I chose this name because I really have no idea how this rocket will turn out, or what it's design will entail.

I started out using the LEGO model of the USS Defiant, which has a center body and a couple of large nacelles as outriggers.

So lets started with a BT-80H body tube and a couple of BT-80H outriggers. These will be glued together and left to dry.

2026-07-21 Forming the BT-80H Sub Assy

I submerged the BT-80H Sub Assy for 5 minutes in cold water, then clamped it in a fixture to make the overall height 2". Clamped the sides to make the BT-80H Tube Fins rectangularish.

I'll release the fixture tomorrow and check it out.

2026-07-22 Tube Forming - 24 Hours Later

Released the BT-80H Tubes from the fixture and there was a small amount of spring back. So I soaked them in water again for 5 minutes and stuck them back into the fixture

CAD

Fired up the CAD Station and knocked out a quick study drawing:

Open Rocket

Used the study drawing to build an Open Rocket model and simulation:

Revised the design.. turned the Nose Cone and Air Inlet Side Pod on the wood lathe, cut and sanded the Air Inlet Side Pods, and then glued them into place.

2026-08-10 Building the Spool, and installing the Launch Lugs

Cut the Retaining Rings using my Scroll Saw, and then sanded them to shape. They were then glued to a BT-52HMF Motor Tube.

The Launch Lugs were cut to length and glued to the Body and Fin Tubes.

2026-08-11 Nose Ballast and Lag Screw Eye

Ended up using a 1" Dia Steel Bar, a little over 2-1/2" long. There were (2) pieces that just happened to work. I cut a 2-1/8" Dia wooden dowel to 1-1/4" Long and drilled it for the Lag Screw. Then slid it all into the Nose Cone counter bore and glued it into place using Gorilla Wood Glue.
