Each set is precision machined from high tensile strength 6061 aircraft aluminum for strength and long life. Sets feature base with coring spindle, convergence cone forming nozzle ram, propellant ram(s) and bulkhead top (flashhole) forming ram. The nozzle ram forms the correct (convergence) angle to dispense pressure and each ram is drilled smaller than the previous to properly accept the spindle tapers. Knurled ends for removal. Each set includes complete instructions with "black powder" type fuel formulas. Case reinforcing sleeve not included. Stock #TSWROC is a whistle rocket tool set that uses whistle mix (potassium perchlorate, sodium salicylate or sodium/potassium benzoates) intimately wet mixed together. The set features multiple stage effects. Includes diagramed instruction booklet.

CAUTION: NEVER POUND WHISTLE MIX TO COMPRESS! ALWAYS USE A HYDRAULIC PRESS FOR CONSTANT PRESSURE WITHOUT THE 'SHOCK' OF HAMMERING!

ROCKET MOTOR TOOLING - BLACK POWDER END BURN GRAINS - 6061 ALUMINUM

Not yet in stock

As with the smaller version hobby store motors, these tool sets produce rocket motors that have longer burn durations than the core burning types. Each set is precision machined from carbon steel and 6061 aluminum stocks for long tool life. The higher density propellant grain (mandatory for proper chamber pressures during combustion) is formed by using a hydraulic press for adequate pressures. The base and spindle are machined from steel to withstand the high pressures exerted on them during the pressing operation.

SILICONE FLUID (POLYDIMETHYLSILOXANE / PDMS) RELEASE & ANTI-FOAMING AGENT

Used as a mold release agent for casting proprllants, it is first applied to the coring spindle, casting mold, etc.. For stick free removal of cast propellants, plastics, epoxies, etc.. Also effectively eliminates foaming when added to composite propellants. 2 drops per 5 lb batch is all that is required. Large 2 oz bottle goes a long way, enough for hundreds of applications.

NOZZLE FORMING TOOL SETS - MOLDED GRAPHITE COMPOSITE ROCKET MOTORS

Machined from high carbon steel and aluminum, these tool sets offer the hobbyist a means to make high heat & erosion resistant graphite composite nozzles for use in higher combustion temp composite rocket motors and others. The sets consist of a heavy wall carbon steel mold sleeve, base with divergence forming cone and a ram which is completely adjustable according to the degree of erosion and heat/gas resistance required. You can design and produce nozzles to burn out slightly for core burning geometries or those that have little or no erosive loss to retain full pressure during combustion for bates grain and moon burning geometries, etc. Make 25 to 50 nozzles per hour for as little as $0.15 each! Using a mixture of powdered graphite and other materials, you simply add a measured amount of mix to the mold sleeve, compress to a mark on the ram and eject. The more pressure used, the higher the density and the more erosion resistant they are. Once you have several, they are cure baked in an oven and drilled any diameter you need for the proper exhaust vent - fully adjustable for pressure release! The sets produce nozzle pellets the diameters listed which are shrink controlled by the oven heat. They are designed to fit the casings listed for each but can be made to fit casings of similar size as well.

NOZZLE MATERIALS - BLANK ROD STOCKS FOR MACHINING

Due to the wide range of burn durations, power ratings and grain geometries to choose from, we have added a variety of blank nozzle stocks for your custom designs. Listed according to their maximum heat resistance properties starting with the highest (lowest erosion) material - GRAPHITE. For those of you who have computer program designs using particular nozzle materials for specific erosion rates, we list their maximum temp resistance. The actual erosion points will be higher. This information supplies you with alternative erosion factors by choosing other nozzle materials. Sold only in increments of one foot. Note; materials listed with no pricing, we do not carry but list the information for your benefit.

EPDM RUBBER - CHAMBER INSULATION

This thin rubber insulation is applied to the inner wall of the motor chamber to insulate the casing from the combustion heat generated during operation, thus increasing the life of reuseable casings and allowing adequate low cost materials to be used as expendable motors. The propellant may be cast directly into the EPDM lined chambers or an additional liner of carbon cloth be placed between EPDM and propellant thus allowing the higher cost EPDM to be used again.

Unused NASA surplus.

Basic applications; .030" = F through I motors,   .101" & .109" = I through K motors,   .215" = L and larger

CARBON GRAPHITE CLOTH HEAT SHIELDING - LINER & GASKET MATERIAL

Used by NASA for heat shielding and protection where direct heat, flame or high heat transfer is a problem. Industrial thermite cannot burn through it!! Flexible cloth-like weave (rayon fibers) which is graphitized under high pressure, leaving a super thin web (.027" thick) enables its use most anywhere including fireproof gaskets and casing liners in rocket motors or other devices, blast plate protection on launch pads or welding applications, firewalls, etc. Use to line inner casings and cast or compress propellants, smoke comps, etc. directly into them for protection from burn-through. Lowest cost insurance money can buy! Easily cut with scissors or punched with disc cutters.Can be "painted" with high heat resisting epoxy or fiberglass resin and sandwiched together in a hot press to form under pressure and heat. Make most any thickness, including blocks for lathe turning into re-useable rocket motor nozzles or nose cones (hollow out for nose cones).

REFRAC 6000 CASTABLE REFRACTORY

   

Stock # REFRAC6
High temperature, high silica/alumina content with Andalusite for excellent resistance to thermal shock, pressure and abrasion from high performance rocket propellants that other ceramic materials lack. It is capable of resisting direct combustion gas heat to 3000° F (white hot) and indirect heat to approx 3500° F. For making nozzles, moisten slightly with water (or sodium silicate) and press in a forming die using hydraulic pressure @ 5000 psi or greater followed by baking at 500° F to remove all traces of moisture. The more pressure used to form, the higher the abrasion resistance will be to pressures and heat. They can be lathe cut for "O" rings or recessed for snap rings, etc.

CARBOSPHERES - CONDUCTIVE CARBON POWDER - HOLLOW MICROSPHERES

This specially developed, low density carbon powder was ordered by NASA for the (now cancelled) New Advanced Space Shuttle Project. The material cost the government well over $125.00 per pound and was never used. We have all 80 drums @50 lbs net each. Although the manufacturer could give us no information on it's application, they did tell us the material is pure carbon, low density (.198 g/cc), light weight, conductive powder of 99.7 wt % passing 50 mesh and 22.7 wt % passing 325 mesh. Capable of withstanding temperatures well in excess of 4000�F and very lightweight, it should make excellent nozzles to increase heat resistance and reduce both weight and abrasive wear on spindle. It may also be used as a mold release agent (dry lubricant) in that it is "slick" like it's older brother Graphite - yet lighter in weight. Also great for use in conductive bridge-wireless electric igniters!! Can be milled to reduce particle size if needed. Full 50 lb drums can be shipped by UPS.
