* Polyethylene terephthalate (aka PET) is a thermoplastic polymer

resin of the polyester family that is used in soda pop bottles. Seri-

ous bodily injury could result from using any other type of bottle.

Tools required for assembly and items needed to launch rocket:

An adjustable wrench (or a 14mm wrench), 4mm & 5mm hex wrench, and

Phillips head screwdriver. A plastic (PET*) soda bottle, nose cone, water,

and air source (bicycle pump, foot pump, scuba tank, or an air compressor).

Soda bottle nose cone is required or rocket will not fly straight:

Create the nose cone by starting a cut with a razor blade or box cutter

about 4" down from the cap and just above the label of a plastic (PET*)

soda bottle. Finish cutting around the bottle with scissors in a straight line.

Check for Leaks

Before heading to the launch field, check

that all seals do not leak. Add a cup of wa-

ter to the bottle. Place bottle onto the

launcher & press down until it locks with a

loud click. Pressurize to 80 PSI with pump

& see if any water is escaping around the

threaded holes of the manifold. If so, pull

the ring on the relief valve to release pres-

sure, than tighten the leaking fitting(s).

Relief valve slits should face sideways to

avoid spraying into eyes when it releases.

Assemble Launcher

With the black cable stop facing you screw

brass parts into the manifold beginning at

the upper left and work clockwise. If no red

sealant, wrap 3 Teflon tape layers around

part threads first. Screw in black hose con-

nector on top. Attach clamp-on cable stop

over hose connector & align. Do not over

tighten clamp as connector will bind /break.

Optional, wrap Teflon tape around threads

of 1/4" SS tube to keep water out of the air

chamber below before screwing it in place.

Mount assembled launcher onto the ABS

base with the SS Phillips screw. Stretch

out brake cable & place fat barrel nipple

into the brake lever slot, thread through,

and secure with silver slack adjustment

ring. Insert other end of cable housing into

manifold cable stop, push hose connector

down & place nipple into clamp-on cable

stop. Remove excess brake cable slack by

ring or screwing in Phillips screw on lever.

Increase or decrease brake cable slack by

raising or lowering clamp-on cable stop.

Upgrade Part Tips

Wrap 3 to 4 layers of Teflon tape clockwise

around threads with threads facing you;

insures that tape won’t come off while

threading into hole. Air pressure gauge &

mini ball valve need to be aligned to face

toward the top or angled slightly to the

front. More wraps of Teflon tape may be

needed for these 2 parts to properly align

on the manifold. Water will run off better

when gauge is installed at an angle and

will read better when launcher is tilted.

Assemble Accessories

Attach brake lever to PVC handle if sepa-

rate.

Insert black reducer into collapsible

funnel. See next page for assembling the

StratoFins and creating a nose cone from

a 2 liter soda bottle. Screw black nozzle on

to StratoFins or your homemade rocket.
