The Super BP Core Burner Rocket Tooling Set for 1 lb (.75" ID) x 7.5" L tubes features modified nozzle geometry to more closely resemble a true De Laval nozzle. The end result is a more efficient rocket motor with a bit more "snort" than traditional BP rocket sets. Plus, the spindles are machined from bronze for durability and a long life. These super BP sets can also be used to produce great whistle and strobe rockets. 

Set includes:
Universal base
Removable spindle, rammers, and stainless puller

All bases and rammers are chemically blackened, surface hardened, marked with no-pass and swap rammer lines, and engraved with tool set name and tube length.
