I have recently started a new project. It's going to be a LOC/Precision Magnum clone using a carpet tube that has the same OD as LOC tubing, but is 1/8" wall. The other nice feature is that it is multiple, alternating layers of kraft paper, then a metal foil. This makes the tube incredibly strong, but a little heavier. I imagine that it is comparable to LOC tubing after being fiberglassed.
I am using the LOC long profile 5.5" cone from my original Magnum. The tubing had to be peeled a little bit at the nose end so that the shoulder would fit the thicker tube. After peeling, the inside was glazed with epoxy to harden everything up and to seal it.
The Main chute bay is 23" long, the Drogue section is 19.5" long, and the fin can is 30" long. Each coupler is 12" of the original tubing, slotted 15/16" lengthwise and glued together with Q-Cell thickened US Composites resin. Then, a layer of 4oz. Satin weave glass was laid across this joint. This resulted in an incredibly strong coupler.
I am still debating whether or not to glass the tubing. It is definately strong enough as it is, but glassing would fill the semi-deep spirals and also give a better finishing surface than the current paper layer.
It's going to have a 36", 75mm motor mount. This way I can use up to an AMW 76-6000 case or AT 75-6400 case (both will never happen), but more importantly there is room for the RATT Works K240 motor, which is going to be having a new reload certified soon, bringing the impulse up to a full K motor with a faster burn. Should be pretty cool!
Here is a picture of all of the tubes lined up.
