Thanks for the kind word, guys.
Looking back over this thread, which is really Bill's, I notice that almost all of my posts are in the winter months during snowstorms (or at least what passes for a snowstorm here in El Paso). Typically, it's sleeting outside right now with snow on the peaks. In any event, I made a little progress today; I did get the lug off and repaired the area on which it formerly resided. That's a piece of cardstock cut to size and yellow glued to the tube. After that dried for a few hours, I blended it in with sanding sticks and then top coated it with sealer. A few passes of 400 grit and it's ready. This repair was key to the whole project as I am not aware of a replacement body tube. The second picture shows the repair on the fin. I squared off the chip and cut a piece of plastic stock to slightly over size for a patch. I then glued it in, making sure one side of it was flush against the beveled front of the fin so I would only have to sand one side. Great plan; It didn't work out that way. Somehow, the Plastruct Plastic Weld liquid cement got under the fin and the glue was hot enough to craze or eat away the adjacent plastic. I scraped off the damaged area and filled with plastic putty. Luckily, I anticipated problems and masked off the fin on the edge of the beveling. I wet sanded the fin and it should be fine under primer. You can see the outline of where the lug will be placed forward of the repaired fin. Next up is the parachute and the nose cone.

Also, Mark, what are the total length and the body tube length of your Nike-Clipper? (I now think it's a Nike-Smoke, as I'll explain.) The 1974 AVI sale catalog lists the Nike-Clipper's total length as 19" (see: http://www.ninfinger.org/rockets/nostalgia/74avi01.html ). *ALSO*:
I just looked up the page in that AVI catalog that lists the Nike-Smoke kit (see: http://www.ninfinger.org/rockets/nostalgia/74avi04.html ), and that Nike-Smoke--which is 19-1/2" long--definitely appears to have red plastic parts (fin unit, nose cone, and launch lug). That MPC/AVI Nike-Smoke, like Quest's Nike-Smoke (see: http://www.ninfinger.org/rockets/nostalgia/94qst16.html [also 19-1/2" long]), also has the single, middle-mounted launch lug, so I was wrong--your model is a Nike-Smoke rather than a RTF Nike-Clipper. If your rocket lacks a 20 mm stuffer tube down inside it, toward the rear (only the RTF Nike-Clipper has that, see: http://www.ebay.com/itm/Vintage-MPC...cef95%7Ciid%3A1 ), then it's a Nike-Smoke.

Blackshire,
Length is 19"+; remember, the tip was missing from the nose cone and while there could have been an internal piston attached to the now-identified-as-plastic engine mount, I kinda doubt it. So MPC Nike-Smoke it is.

Not a Nike-Clipper. I own several of those. The Nike-Clipper is an all plastic (except for the inner 18mm tube for the motor) RTF rocket.

In his "Handbook of Model Rocketry," G. Harry Stine listed the following "construction howlers" that he had seen in beginners' model rockets, but what your Nike-Smoke has ^isn't^ listed there: 1. A nose cone glued into the body tube; 2. A motor mount glued in backward; 3. A solid bulkhead glued across the inside of the body tube; 4. Recovery wadding glued into the model; 5. Balsa fins that were cut out with a pair of scissors ("But, Mr. Stine, it makes such a nice, fuzzy edge for gluing!"); 6. A model rocket motor glued into the model; 7. A saddening parade of model rockets with crooked fins, too-small fins, fins glued onto the nose, no launch lug, launch lug mashed flat, no motor mount, shock cord not glued in, and body tube crimped or bent. BUT: In any event, I think your rescue operation is well worth doing. Quest Aerospace (see: www.questaerospace.com ) still offers the Nike-Smoke fin unit/motor mount and the Nike-Smoke nose cone (including the tip that's missing from yours), so you could replace--or perhaps 3D print a duplicate, in red ABS plastic--the missing nose tip. (Plus, I'd like to see Quest re-issue their Nike-Smoke kit. Even if they no longer have the plastic launch lug [which could also be 3D printed, if desired], an ordinary launch lug--glued atop a short balsa standoff--would be a perfectly usable, and lighter and lower-drag, replacement. If enough of us "lobbied" Quest, they might re-issue the kit; it would fly very nicely on their new Q-Jet composite motors.)

I have DELIBERATELY glued nose cones and engines in beat-up models ensuring a DESTRUCT-O send-off final flight.
The last one I did that with was an Estes Polaris with a 24mm D11-9.

There was a fatality a couple years ago in California when someone was allegedly doing a final sendoff of an old rocket and it struck some unfortunate on the way down.
Ballistic recoveries are an unfortunate part of rocketry - sometimes sh"" happens. But you don't want it do it on purpose. It's simply too dangerous. |
