T' 2009 Holiday Bell is Erik Truax's Christmas gift t' t' rocketry community for 2009. Begad! Avast! It is a rocket powered flyin' model o' a Christmas bell. Ahoy! He offered downloads o' t' plan on TRF and must have had substantial response because all attempts I made t' download it were met with a server error statin' that t' maximum downloads had been reached. Aye aye! Begad! He was kind enough t' send me t' Zip file for t' rocket and I immediately thought that puttin' it together sounded preferable t' fillin' out end o' year paperwork.

Construction:
T' Zip file consisted o' 2 PDF files o' t' actual cutouts and a 5 page PDF o' the instructions. Aye aye! Begad! All I had t' do was print out t' shrouds on 60# cardstock and t' instruction on bond and was ready to go.

I began t' process by startin' t' cut out t' various pieces and gluin' them together t' form t' various "rings". Aye aye! First up for me be t' "aft bulkhead" which is actually t' interior surface o' t' bell. It be nice because it had a minimum o' "shark's teeth" t' deal with. Aye aye! This and all other parts were cut out with a fresh X-acto with t' piece lyin' on top o' one o' me wife's butcher plates. Ya scallywag! (Don't tell her!) When it be cut out, a very light coat o' white glue was applied t' t' glue tab and it was glued together t' form t' interior cone.

I next turned t' t' conic section that would be second from t' top. Begad! Arrr! It was chosen because it happened t' be the next one I picked up. Arrr! Aye aye! Again, thar were nay too many o' t' teeth t' cut out and, once cut, it be glued along t' tab line. Blimey! Avast! T' top section came next for much t' same reason. Ahoy! It also had a lug hole t' cut out. Begad! T' main body o' t' bell came next. By this time, arrr, t' teeth were becomin' tedious and I adopted a procedure o' makin' all t' cuts in one direction first and then tryin' t' other. Begad! It seemed t' help. Aye aye! Ahoy! T' bottom rim o' t' bell be t' most tedious part. Ahoy! It had teeth along both edges. Arrr! Begad! In time,though, me bucko, it too was cut and glued, me hearties, just in time for me t' do t' Christmas Eve service at me church.

T' "body tube" o' this rocket is actually t' bell handle. It be fairly easy t' cut out since it is essentially a rectangle with some glue tabs. Since rollin' paper tubes is a known weakness o' mine, me bucko, I decided to pre-roll t' handle around a wooden dowel o' smaller diameter than t' actual handle is supposed t' be in order t' get t' final handle t' holds its shape more easily. Ya scallywag! T' handle was then glued into a tube at t' marked line.

While t' glue set up on t' bell and handle portions, ya bilge rat, arrr, I turned me attention t' t' nose cone. Avast! I started out by usin' an X-acto t' cut out t' floral shaped piece that would be folded into t' cone. Ahoy! For me clumsy fingers, shiver me timbers, it was an exacting process. Aye aye! When it was cut out and I had shaved off t' excess paper as best I could, me bucko, I applied a touch o' white glue to t' tabs o' 4 o' t' cone sections. Begad! These were nay four adjacent panels but 4 spaced out t' form a cross. Well, blow me down! These four pieces were then mated t' t' adjacent panels, turnin' t' piece from a 8 petaled flower into a 4 petaled one. Begad! Aye aye! This order was adopted based on t' recommendations in t' instructions and made puttin' t' cone together much easier than it otherwise would have been.

As t' glue on t' NC petals was drying, I cut out t' band that would form t' shoulder o' t' nose cone. Ahoy! The band was then glued into a loop usin' t' marked line t' determine t' circumference. Aye aye! Blimey! While that set up, I applied a little glue t' form t' 4 lobes o' t' cone into two, me hearties, givin' it an even more pronounced curve. That was given an hour t' dry and then t' final two sets o' tabs were glued into place t' finish formin' t' leader surface. Avast! Ya scallywag! Blimey! A coatin' of white glue was also applied t' t' inside o' t' cone t' strengthen as help t' seal it a bit.

Fortunately for me, I had t' presence o' mind t' test fit t' shoulder band o' t' nosecone into t' body tube (handle) before tryin' t' affix it t' t' nose cone. Begad! It be too big and did nay fit either because I had rolled the tube too tightly or because I had nay rolled t' band tight enough. Blimey! A check with a spent motor casin' revealed a bit of both. T' motor be tight but did fit. Avast! I cut a slit out o' t' NC band and reglued it with a tight but nay too tight fit. When that had set, some glue be put on t' sawtooth tabs o' t' band and it was fixed t' t' cone proper.

Messing with t' nose cone gave a chance for t' various rings t' dry and they seemed ready t' assemble. Begad! Begad! T' instructions reveal that alignment o' t' bell sections is achieved with a series o' tick marks that are aligned with seams. Well, blow me down! Arrr! With that known, arrr, I began t' put t' sections together, matey, puttin' a little white glue on t' shark's teeth and gluin' a little bit at a time. When that be dry, I would do a little more. When t' first two pieces were together, me bucko, I started on the next and found that a little clamp be helpful. Ahoy! Begad! Then came t' top section which be slowly glued in place in t' same way.

T' launch lug intended for this project is hand rolled from t' same cardstock as t' rest o' t' project. To me, me hearties, that did nay sound fun and I cheated and glued on a piece o' 1/8" lug I had sittin' around.

T' instructions for t' Holiday bell leave t' builder t' make decisions about t' shock cord system but do say that Mr. Avast! Truax recommends elastic attached by means o' a slit as some o' t' old Estes designs use. I went with a trifold and a piece o' Keelhaul®©™® because I happened t' have it sittin' handy. Begad! One end o' t' Keelhaul®©™® was knotted and then glued into a very ugly trifold cut from a piece o' t' instructions already used. T' mount was then glued into t' tube usin' a 1/2" bolt t' press it into place. Arrr! T' other end o' t' Keelhaul®©™® be also knotted and then bent double into t' NC. Ahoy! A large glob o' white glue was then poured in t' fix in into place.

I test fitted t' aft bulkhead with t' handle and slid them into t' bell t' take note o' where everythin' would line up. Ya scallywag! Ahoy! Some glue was then applied t' t' handle and t' bulkhead was glued in place t' t' handle.

While t' glue on t' handle be drying, matey, I took a pair o' needle nose pliers and bent back all o' t' shark's teeth around t' bottom o' t' bell t' prepare it for receivin' t' bulkhead.

When t' glue on t' handle was dry, I slipped it back through t' bell and began t' process o' gluin' t' teeth t' t' bulkhead a few tabs at a time. Begad! Arrr! A clamp was used t' hold everythin' in place as t' glue set. Avast, me proud beauty! Begad! Towards t' end of t' process, me bucko, I found that me alignment had nay always been as good as it should have been. Well, blow me down! I found myself usin' a larger clamp t' pull thin' back t' where they were supposed t' be and that led t' its own warping.

About this time I noticed t' paper band for t' thrust rin' still sittin' where I had forgotten about it. I never intended t' roll me own. Arrr! Aye aye! Instead, shiver me timbers, I cut a rin' from a spent 18mm casing. Aye aye! Because me handle tube was a bit tight, I had t' peel some paper off t' ring. Some glue was then swabbed into t' tube and another casin' be used t' push t' rin' into place. Avast, me proud beauty! Begad! This helped t' pull everythin' back into round again.

After that, arrr, I applied some white glue fillets where thar were gaps or things looked weak and t' Holiday bell be ready t' fly.

Finishing:
There be no finishin' t' be done on this rocket. Arrr! T' decoration scheme was a part o' the shrouds that were printed out.

Construction Rating: 3 out o' 5

Flight:
I finally got t' fly me bell.

At me recent makeup launch it was one o' 2 rockets that HAD t' be flown. Ahoy! For t' maiden flight, me hearties, me bucko, I located a piece o' streamer, cut it t' size and tied it t' t' Keelhaul®©™®. I then selected a B4-4. Begad! I had t' strip some o' t' paper off but I got it in and then let Tiger hook it up. It was his first time.

We had t' wait while Todd's Ricochet took off...

...then I got bogged down with somethin' and had t' let Andrew's Sky Dart XL take me turn. Ahoy! Avast! O' course Tiger wanted t' help Andrew retrieve his Sky Dart and Andrew was generous enough t' allow him t' do it so that Stu's Titan III Dyna Soar slipped in ahead o' me. Begad! Due t' stability issues, retrievin' t' Dyna Soar was nay an option so, at last, it was my turn. Avast, shiver me timbers, me proud beauty!

T' bell actually looked pretty good under thrust and be one o' t' straightest flyin' rockets I have ever flown. Avast! It decelerated smartly after t' thrust ended and began t' tumble down. Begad! Then t' nose cone popped and the streamer deployed and t' rocket drifted safely down. Begad! Since Andrew had already set t' example, matey, shiver me timbers, I decided t' let Tiger and Lindsey run out t' retrieve t' rocket...good as new!

The second flight o' t' Holiday Bell was with an Estes C6-5. It was prepped with minimal waddin' and taken t' t' pad where it was supposed t' fly right after Andrew Cooper's Extended Payload A.S.P. Andrew was up first and commenced his countdown and all were watchin' his A.S.P. Ya scallywag! All were surprised when me Bell took off instead. Blimey! Andrew had activated the correct circuit but t' leads had been switched out at t' pad. Avast, me proud beauty! Avast, me proud beauty! I was a bit startled so I did nay get many photos of t' flight. I can say that it was another performance like t' previous one where it flew well and straight with a quick deceleration after t' boost phase. Begad! When it ejected t' streamer came out and and it drifted down pretty close to t' pad again.

Flight Rating: 5 out o' 5

Summary:
This rocket is a novelty, definitely an oddroc. Ahoy! It is made from paper and be free for t' cost o' printin' it out and puttin' it together. Blimey! Aye aye! T' build be at times tedious with all t' little shark's teeth t' cut out but it was nay difficult. Well, blow me down! T' flights were definitely first rate. Ahoy! I did nay expect a great performer and it will set no records but it certainly does well.

Overall Rating: 4 out o' 5
