Firework missile parts?
Hello All,
In the very earliest Estes catalogs, they offered--in addition to the model rocket parts with which we're familiar today--plastic fin units and nose cones for firework missiles. (This isn't at all surprising, since Vern Estes was originally in the fireworks business before he got into model rocketry.) Now: As well as the fit-onto-tube conical missile nose cone (see: http://www.ninfinger.org/rockets/ca...61/261est4.html ), and the "Bastille-style" trailing delta fins, fit-onto-tube missile fin unit (the Dirty Bird III rocket plan used one, with a regular ogive model rocket nose cone), Estes also offered a fit-over-tube, "Spin Fin" firework missile fin unit (both of these fin units can be seen *here*: http://www.ninfinger.org/rockets/ca...61/261est6.html ). This polyethylene plastic fin unit fit over their BT-1 (0.840" Outside Diameter, I think) body tube, with slight modification of one tube end being necessary for a proper fit (I think the tube was a bit wider than the "Spin Fin" unit's inside diameter), and: I have seen the conical plastic nose cones and "Bastille-style" plastic fin units for firework missiles available as separate parts from time to time, but I have never seen the polyethylene "Spin Fin" units except in that Estes catalog. Does anyone still make them, anywhere? If so, they might be good for group rocket building & flying activities, especially introductory ones for younger kids. Its fins are also somewhat reminiscent of those of the Atlantic Research Corporation Metroc meteorological rocket (a "little sister" to the Arcas, it boosted a 2 pound sonde payload to 20 miles altitude), and could be used for a semi-scale Metroc model. Many thanks in advance to anyone who could help!

I found one of those spin-fin units on a beach on July 5th . . . in 1971 or so.
Any item which it simply not made any more, I suspect. If one could be found, it could be 3D printed and reproduced. I have been hoping to find a source of the other delta-fin firework fin cans, but the supply of those seems to have dried up as well. (FireFox no longer carries them.)

was in a fireworks shop the other day and saw some skyrockets with delta overhang fin cans, but they looked a *lot* thicker/heavier than the pictures I've seen of the Dirty Bird, etc. Plus, it wasn't *quite* the same shape. But anyway, were the original parts that thick? I estimate close to 1/8" thickness.

The ones I saw in the 1970s were at least 1/8" thick.

In the 1980s or 1990s, one of the consumer fireworks companies that I ordered from (Blue Angel Fireworks or Neptune Fireworks) offered a large--about 1" diameter--missile that looked very much like the Centuri Payloader II (see: http://www.ninfinger.org/rockets/ca...2/772cen12.html ); its fin planform was virtually identical to the kit's, and its nose cone was a long cone with a radiused tip, which fit into the body tube like a model rocket nose cone. It even used a rod-type launcher and launch lugs (it came on a plastic base with two 1/8" [or maybe 3 mm, being made in China] diameter rods that fit through lugs on either side of the missile; the rods were slightly shorter than the ~15" - ~20" long missile).

A few found fireworks nose cones that fit pretty well on model rocket tubes.
From left to right: LT125 (also fits ST13 ), BT20 and BT60. The LT125 and BT60 cones are flush with the OD of the tubes. I used a piece of LT115 tube to fit the LT125 and a JT-60c coupler for the BT60. The BT20 cone fit over the tubes.

For mini motor rockets, nose cones from 1 ounce skyrockets (here are some: http://www.tntfireworks.com/firewor...t-assorted-8-oz ), similar-size firework missiles, and perhaps even--if large enough ones are made--ammunition "snap caps" (plastic "simulated bullet" cartridges that are used for "dry-firing" practice) could be used as model rocket nose cones. Making a quick Google search, here are firework missile and rocket items with plastic nose cones (or nose cones *and* fin units), some of which I've never seen before; they are: "HUGE Saturn Missile Battery" (its missiles are about BT-20/ST-7 size, with "Big Bertha"-like elliptical nose cones): www.musiclessons.com/youtube/watch?v=Ou-3d74KiWE "Wolf Pack Missiles" (these have conical nose cones, Iris-like fin units, and dual-rod launchers): http://ferrebeekeeper.files.wordpre...14/07/l-017.png "7 inch Warhawk Missiles" (the missiles have nice swept fin units and radiused-tip conical nose cones): http://keystonefireworks.com/shop/7-warhawk-missiles/ "12 inch Warhawk Missiles" (a 12" version of the 7" Warhawk Missile, these have 5:1 ogive nose cones and tubes wider than their fin units): http://keystonefireworks.com/shop/12-warhawk-missiles/ "12 inch Europa II Missile" (these look very much like the "12 inch Warhawk Missiles," but their fin cans are sized to fit their larger body tubes): http://www.fireworks.com/products/i...-missile-l-018/ "7-inch Neptune Missile" (these have short conical nose cones and six-finned fin units that resemble the Petrel sounding rocket's fin assembly): http://redrhinofireworks.com/6-inch...ne-missile.html "7 inch Missile" (resembling the "7 inch Warhawk Missile," their fins are more 'angular'): www.wildwillysfireworks.com/products/7-missile
