MT. CLEMENS, Michigan USA — PML is excited to announce two important items. A totally new airframe product, and reduced retail pricing on existing phenolic airframes.

After large investments of time & capital, plus months of extensive testing, we are proud to deliver a totally new airframe tube for the rocket industry.

Public Missiles Ltd. will introduce the new Quantum Tube on May 12, 1999. These new tubes are made in the USA from a special blended polymer that is extremely durable and easy to use. You will find this new material easy to work with and very forgiving, even during those "less than perfect" flights.

Most epoxies and paints will readily adhere to this material. The Quantum Tube has been tested and found compatible with the following paints: lacquer, enamel, epoxy and urethane, as well as many different primers. The Quantum Tube can be squeezed, dropped, or even thrown and will not suffer any damage as can sometimes occur to cardboard or phenolic tube. The Quantum Tubes are molded in medium gray and have a glass smooth finish.

The Quantum Tube does have one thing missing: the spiral groove!!! You will appreciate the fact that you no longer have to fill and sand the airframes to achieve the perfect finish.

We will initially introduce the Quantum Tube in 2.15" ID and 2.56" ID diameters, at $9.50 and $10.95 respectively per 36" section. These tubes will be phased into all of our kits of those diameters. Shortly after this introduction we will release Public Missiles Ltd. Quantum Tube in the 3.002 ID and 3.90 ID diameters. The 3- and 4-inch kits will then be upgraded with the Quantum Tube as well. The Quantum Tube can be purchased separately and will be priced lower than what the current phenolic retails at. All Quantum Tube part numbers will be prefaced with the letters QT, such as "QT-2.152".

Our premium phenolic tubes will still be available in all popular sizes. Motor tubes and other internal components will remain phenolic as they always have been. All phenolic airframes through PT-7.512 will be reduced in price as much as 19% (depending on the diameter). Phenolic tubing pricing, effective May 17, 1999 is as follows:

PT-1.145, $6.95
PT-1.525, $7.95
PT-2.152, $9.50
PT-2.560, $9.95
PT-3.002, $11.50
PT-3.900, $12.95
PT-6.007, $29.95
PT-7.512, $34.95

Below is an "Important Notice" document about using the Quantum Tube.

IMPORTANT NOTICE: PLEASE READ BEFORE USING THE QUANTUM TUBE (QT)
The Quantum Tubes have be tested and found to be compatible with most paints and epoxies. Paints tested were lacquer, enamel, epoxy, and urethane, including various primers. As with any paint, apply several light coats allowing each to flash before re-coating. Most brands of epoxy adhesive bond well with no adverse affect to the tubing. The bonding area must be sanded prior to applying epoxy. Follow the suggestions in "Do's and Don'ts" below.

The Quantum Tubes are resistant to the heat of ejection charges. As with any tube, repeated ejections will leave a black, gritty residue inside the tube. To remove the residue simply wipe the tube interior with a wet cloth wrapped around a dowel or broom stick and allow to dry.

DO'S AND DON'TS FOR USING THE QUANTUM TUBE (QT)

Do's:

Before applying paint to the QT lightly sand the outside of the QT using 320 or 400 grit sandpaper.

Sand the fin fillet area on each side of fin slots using 150-grit sandpaper before applying epoxy to fin and tube.

Use the edge of an X-Acto knife to de-burr cut ends of QT.

Sand the inside area of the QT using 120 or 150 grit sandpaper wherever parts are to be epoxied to the QT. Most hobby epoxies can be used with the QT. Sandpaper flappers on a drill, sandpaper glued to a large wood dowel, sandpaper on the end of a stick, etc. can be used to prepare the inside of the QT for epoxy.

Using alcohol or mineral spirits will not damage the gloss finish on the QT.

Don'ts:

Do not wipe or spill lacquer thinner or acetone on the Quantum Tube, either will melt or distort the tube.

Heavy amounts of CA (cyanoacrylate, "super glue") may distort the QT.
