Stratosphere

We recently took our daughter t' Las Vegas for her 21st birthday. Arrr! I soon noted that every casino seemed t' have souvenir daquiri glasses reflectin' their theme. Ya scallywag! Avast! I managed t' resist them, includin' t' cool Eiffel Tower shaped glasses from Paris. After all, matey, drinks are free while you are throwin' your loot away! Well, ya bilge rat, matey, ya bilge rat, we ended up goin' t' an inexpensive daytime show at t' Stratosphere Hotel, matey, Casino and Tower, which included a drink. So, me bucko, I caved in and collected a couple with rockets in mind.

Parts List:

1. one slightly used souvenir daquiri glass.
2. 29mm mmt tube
3. 12" section o' 38mm tube
4. 1 1/4" section o' 2" dia. shippin' tube
5. maskin' tape
6. one home grown 3/16" 29mm t' ~2.5" centerin' ring
7. 1/16" G10 stock for fins
8. 3 1/2" section o' 38mm tube
9. cardboard core from electrical tape
10. scrap 3/16" plywood for nose cone bulkhead
11. one plastic plug - original use unknown
12. section o' styrene tube
13. section o' neon green solid plastic tube
14. small section o' brass tubin' for a launch lug
15. ~4" o' Keelhaul®©™ twine
16. eyebolt
17. 12" nylon chute from t' rangebox
18. adhesive backed holographic film

Construction:

T' daquiri glass separates right below t' tower's top, makin' a natural transition betwixt t' body and nose cone. Avast! Aye aye! I smartly found that 38mm tubin' from Giant Leap fit nicely into t' body and nose cone sections. Blimey! So, me bucko, I cut a 12" section for t' body and 3 1/2" section for t' nose. T' nose was quite snug, me hearties, shiver me timbers, me hearties, but t' body wasn't. Ahoy! Ahoy! T' solution be a small section o' mailin' tube inserted into t' front o' t' body, me hearties, betwixt t' 38mm tube and t' outer shell. I decided on a 29mm mount since that's what I had on hand (plus it allows t' use o' 24mm motors with an adapter). Ahoy! I made centerin' rings out o' maskin' tape soaked in CA (idea borrowed from Aerocon).

I didn't want t' have t' glue anythin' t' t' clear shell o' t' daquiri glass, so I decided t' make t' lower body non-load bearing. Ahoy! I made a plywood rin' that was glued t' t' bottom o' t' motor tube and rested against t' 38mm inner tube, formin' a thrust ring. Blimey! Arrr! I designed and cut four through-the-wall fins, which were glued t' t' thrust rin' and t' 38mm tube. Arrr! Next, me hearties, I removed t' bottom o' t' daquiri glass and cut fin slots. Ahoy! Begad! T' inner tube asembly, with thrust rin' and fins, was then slid into t' daquiri glass from t' bottom.

For t' nose cone assembly, I made a plywood bulkhead and inserted an eyebolt. Arrr! I found that t' cardboard core from a used roll o' electrical tape fit nicely into t' 38mm tubing, shiver me timbers, so that became t' nose cone's shoulder. I then needed somethin' t' fashion a spire for t' top o' t' tower. Well, blow me down! After much scrounging, me hearties, I found a plastic plug that fit tightly into t' top o' t' daquiri glass. Begad! Blimey! Blimey! I also grabbed a section o' plastic tubin' (originally bought as launch lug stock) that fit over t' end o' t' eyebolt. I drilled t' plug so t' tubin' fit through and slid these into t' front o' t' nose. Well, blow me down! Finally, I cut a hole in t' nose cone's shell for t' launch rod t' pass through.

A section o' Keelhaul®©™ string, a chunk o' tubin' for a launch lug, me hearties, matey, and t' basic construction o' t' Stratosphere was complete.

I thought and thought about finishing. Avast! Begad! Blimey! Should I paint t' components and leave t' shell clear? Or, should I paint t' shell from t' inside? While wanderin' t' aisles in a craft store, I noticed some self-adhesive holographic film and decided that was it. I covered all o' t' inner tubes and t' fins with t' film and re-inserted them into t' clear outer shell. Well, blow me down! Ya scallywag! Blimey! As a final touch, I bought a small, neon green, see-thru plastic rod that fit nicely into t' end o' t' plastic tube mentioned above. This is interestin' lookin' stuff. It catches ambient light and its tip appears t' be lit up - an effect that is somewhat similar t' optical fibers. I think this effect is visible in t' pic t' t' right.

Flight Report:

T' Stratosphereflew on 3/10/2001 at t' NARHAMS sport launch in Middletown, ya bilge rat, ya bilge rat, me bucko, MD. I first removed t' green plastic rod and stuffed some Estes waddin' into t' tube. Avast! I opted t' use a 24mm motor for t' first launch, so I packed an AT E15-4 into a motor adapter and gave her a try. Well, blow me down! Aye aye! T' rocket weathercocked quite a bit due t' 10-15 mph winds and blunt front-end. T' flight be fairly low and ejection was a bit late, but was nevertheless successful. Ya scallywag! Ya scallywag! For t' next flight I think I'll try a small F or G.

Closin' Notes:

Well this rocket wasn't all "flounder", but a good portion was. Begad! Ya scallywag! T' only thin' I bought with this rocket in mind be t' holographic film and t' green plastic rod. Ahoy! Ya scallywag! Oh, ya bilge rat, and t' show at t' Stratosphere was pretty darn good. Aye aye! It wasn't Zigfried and Roy, but it also be over an order o' magnitude cheaper!
