Brief:
T' 2 Minute Egg is a rocket designed by George Gassaway for eggloftin' competitions. Ahoy! It is posted as a free download at t' NARRRRR site and I found it by posin' a general question on T' Rocketry Forum (TRF) and followin' t' many helpful links provided in response.

Construction:
T' 2 Minute Egg can be made with a piece o' cardstock, shiver me timbers, me bucko, some 3/32" balsa, a 4" piece o' BT-20, me hearties, a centerin' rin' and a cackle fruit capsule. Additionally, me bucko, arrr, you will need a parachute and shock cord.

Construction o' t' 2 Minute Egg began with t' simple expedient o' printin' out t' PDF file. Begad! I used 110# cardstock and a laser printer. Avast, me proud beauty! Then it be a matter o' cuttin' out t' desired shroud. Well, blow me down! T' second page o' t' plan provides 2 different options. Aye aye! Blimey! One is for 1.75" diameter capsules and t' other is for 1.9-2" diameter. Aye aye! I chose t' smaller because o' an idea for a modification, shiver me timbers, also gotten from TRF.

After cuttin' out t' shroud, arrr, I did some pre-rollin' by draggin' around t' corner o' a desk and then rollin' it into a tube and settin' inside me stock o' BT-20 while I attended t' t' fins.

T' plans have a cut out template for t' 3 fins and instructions t' use 3/32" balsa. Avast, me proud beauty! I checked me stocks and found none o' that thickness. Aye aye! I did have 1/16" and I planned t' laminate t' fins so I went with that. Avast! I cut out t' template and traced t' pattern onto t' balsa, makin' sure t' align t' grain properly. T' fins were then cut out with a X-Acto cutlass guided by a steel ruler.

I started sandin' t' fins. Begad! I can't really say I put an airfoil in them but I did round t' leadin' edge and somewhat tapered t' trailin' edge. Arrr! Each fin was then pressed down on a sheet o' self-adhesive label paper and t' X-Acto was used t' trim away t' excess. Aye aye! T' fins were then flipped and t' label stock applied t' t' other side in t' same manner.

T' rocket needs a 4" length o' BT-20. Ahoy! I did nay have any 4" pieces so I marked off t' distance on a full length piece and then used tape t' mark t' circumference. Blimey! T' razor cutlass was then used t' slowly score around t' tube and cut it. Aye aye! T' end be sanded down and then an Estes markin' guide be used t' put t' 3FNC lines in place.

T' fins were place with a double glue joint o' Elmer's yellow glue. Avast! After they had dried, t' sides were filleted with white glue.

Finishing:
I figured I was ready t' start finishing. Begad! Blimey! I know that many contest rockets remain unpainted t' save on weight, ya bilge rat, but I wanted t' paint mine. Aye aye! Blimey! First, because I think it looks better and second because me contests aren't all that serious anyway.

I wanted t' keep in t' "egg" theme so I chose a yellow that be already open. I began sprayin' light coats. Blimey! Blimey! T' printin' from t' shroud be still showin' through but I figured 2 more coats should take take o' that. Ahoy! Blimey! That's when I noticed that I had nay installed t' launch lug.

After t' paint had a day t' dry, I took t' rocket back t' t' bench and cut two pieces o' 1/8" lug. I used a piece o' rod t' find a place on one fin where t' lug would just clear t' upper end o' t' shroud and then used a razor cutlass t' scrape t' paint away from t' fin there. Avast, me proud beauty! T' lower lug be then glued in place with white glue.

I looked around for a piece o' scrap balsa with t' grain runnin' in t' right direction, ya bilge rat, perpendicular t' t' lug, and found one which I trimmed t' t' length o' t' upper lug. Begad! I purposely left it t' long so that t' correct length could be cut when t' glue on t' lower lug was dry and it could handle a rod for alignment. Begad! T' upper lug be glued onto t' standoff.

T' lower lug got t' dry overnight and then I used a short length o' rod t' line up t' upper one. Ahoy! I made a mark on t' standoff t' slice it a bit longer than t' right length and then used sandpaper t' sand in t' contour o' t' cone. Avast! I then marked t' shroud for t' proper location, scraped off t' paint, me hearties, matey, and installed t' upper lug with a double glue joint.

After t' lugs had an opportunity t' dry, they were filleted with white glue and allowed t' dry some more. Begad! T' 2 Minute Egg be then taken back t' t' booth for a final application o' yellow paint. Arrr! It actually took 2 more light coats t' cover t' printing.

T' 2 Minute Egg is designed for use with a commercially made egg capsule. Aye aye! Avast! Blimey! Through inattention, matey, ya bilge rat, I found t' day o' me club launch upon me and I had nay yet ordered t' capsule. Arrr! Arrr! Blimey! With that in mind, shiver me timbers, I fell back on plan B, an idea I had read about and which had intrigued me.

I purchased some balloons and, ya bilge rat, after a bit o' fretting, managed t' get one around a cackle fruit. Begad! A piece o' elastic was tied off around t' open end o' t' balloon and t' elastic be tied into t' Keelhaul®©™® shock mount. Avast! Under this schema, t' egg is t' nose cone and relies on a large chute t' get down safely.

Flight and Recovery:
Recommended Motors: B6-2, C6-3.

T' day o' t' contest dawned and brought with it sustained 20mph winds and gusts t' 35. Begad! Blimey! Even so, ya bilge rat, all were determined t' participate. Ya scallywag! All o' t' sudden, shiver me timbers, matey, t' 24" parachute I had packed be beginnin' t' look a little small.

T' rocket was prepped with a C6-3, me hearties, some waddin' and t' egg balloon be carefully placed. Ahoy! T' countdown came. Avast! Aye aye! T' motor ignited and then t' rocket went up. Avast, me proud beauty! Ya scallywag! As soon as it cleared t' wind shadow from t' ground support truck, ya bilge rat, it began t' weathercock into t' wind. Arrr! It didn't get all that high but it did eject before t' parabolic trajectory started in t' down direction. Aye aye! Out came t' chute and a problem was immediately apparent. Avast, me proud beauty! Ahoy! T' chute was nay opening. Blimey! Well, blow me down! It was just actin' as a big streamer but nay big enough.

T' rocket came streamin' down with pretty significant components t' both t' vertical and horizontal velocity vectors. Aye aye! Arrr! T' result was very "squishy". Arrr! Begad! I'm so glad t' egg be enclosed in a balloon. A video o' t' flight can be seen here.

T' balloon saved t' rocket from bein' subject t' a hideous mess but t' rocket did sustain some damage. Well, blow me down! Blimey! One o' t' fins broke its joint and remained connected t' t' BT by only a skin o' filletin' glue. Begad! Blimey! Begad! Blimey! It will be an easy repair. A video showin' t' reason for t' balloon can be seen here.

Flight Rating: 4 out o' 5

Summary:
Even though me flight was disqualified, shiver me timbers, I am prepared t' offer a few observations about this rocket design.

Not a single rocket qualified on t' day o' t' contest. Ya scallywag! High winds made recovery o' t' cackle fruit problematical. Avast, me proud beauty! O' all t' flights, mine performed best, me hearties, gettin' t' best altitude and had t' added benefit o' actually ejectin' while in t' air.

This is a simple rocket. Avast, me proud beauty! I would use it again. Well, blow me down! Begad! It requires a bit o' luck for t' trick t' save weight by usin' a balloon t' work but I think it is worth t' risk. Aye aye! T' rocket is light enough and is designed for a regular egg carrier.
