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:​

Pegasus XL... A Scratch Build

The Pegasus XL is such a great design. It's launched from the belly of a jet and carries satellites into space. Not a new concept... but a very cool concept.

This version is based on a BT/C-204 body, has a 29mm motor, and a rear eject spool. 
 
 
 
 



 

2026-07-07 How about a two stager.... I mean the real thing is a two stager.

Used some canted fins on the rear of the sustainer, to attempt some stability of the 2nd stage... then using a Quick Fuse in the 2nd stage to light the BP motor from the composite motor.​
Those second stage fins in the simulation aren't really there in the actual model... they are used to make that stage stable in the simulation.​
