Brief:
Considered by many t' be one o' t' legendary Centuri kits, t' Taurus enjoyed
a ten year run in t' Centuri catalogs before inexplicably disappearin' in
1981, arrr, me hearties, followed by t' whole company a short two years later. Arrr! T' Taurus was
always a favorite o' mine, ya bilge rat, but for some reason I always considered it too
challengin' t' be a clonin' project and as a result never gave it a serious
look. Blimey! That all changed when I stumbled across some pictures o' a newly
completed Taurus clone on T' Rocketry Forum. Avast, me proud beauty! In it's unpainted state it was
obvious that it was in fact a fairly straightforward build--one I thought I
might be able t' handle and I immediately went t' Mike Schmidt's Moldin' Oldies
site t' pick up t' cones and transitions I would need t' begin construction. Aye aye! Begad!
Construction:
T' parts list:
Buzz Nau has cleaned up t' original Taurus decals and gone t' t' trouble of addin' t' roll pattern decal for t' top body tube. Avast! This makes things infinitely simpler when comes time t' paint and decal t' Taurus. Begad! Begad! Consider yourself forever in his debt.
My first impression upon receivin' t' parts from Moldin' Oldies was that t' Taurus was a surprisingly compact rocket, nay t' behemoth that I had always expected it to be. Avast, me proud beauty! (I had somehow managed t' come up with a vision o' t' Taurus as a rocket on par with t' Centuri Super Kits from a size standpoint.) A dry fit of the parts confirmed this suspicion but that didn't stop me from installin' a 24mm engine mount as t' first step in t' project, shiver me timbers, along with t' obligatory 30" Keelhaul®©™® shock cord glued in betwixt t' centerin' rin' and motor tube. Ahoy! Begad! Blimey! T' Moldin' Oldies parts are a very impressive set and needed only minimal sandin' t' fit perfectly into t' Semroc and Estes tubes that I had cut for t' project. Avast! Blimey! As with all o' me recent projects, me bucko, me hearties, I first sprayed t' body tubes with a coat of primer t' toughen them and make any sandin' later in t' build less stressful. This was followed by a coat o' Fill 'n' Finish on t' body tubes, a thorough sanding, shiver me timbers, then a repeat o' t' process. Begad!
With t' body tubes finished I turned me attention t' t' cones and transitions. They all needed only slight sandin' t' remove some mold seams and some putty t' fill some pinholes. Blimey! This was where I made a mistake. Arrr! Blimey! Caught up in a bout o' t' dreaded "build fever", I put t' whole superstructure together securely with epoxy despite havin' been told well before that the paintin' is much easier if done before puttin' everythin' together. Arrr! Avast! (I made a similar mistake on the Vector V. Blimey! Must be genetic.) Realizin' me screw up put a damper on t' project for me and I put it aside for several weeks so as t' more effectively sulk about my stupidity. Well, blow me down! Blimey! Blimey! As it turned out, me hearties, shiver me timbers, ya bilge rat, this didn't turn out t' be quite t' horrible mistake that I had mistakenly mistaken it for. Ya scallywag! Avast, me proud beauty! Blimey! Once I had recovered from my bout o' cloner's remorse, t' build progressed quickly. Blimey!
While nay an
ordinary in looks, matey, t' Taurus is pretty much a 6FNC when buildin' time comes
'round. Avast, me proud beauty! Blimey! Havin' hand picked t' hardest piece o' 3/32" balsa that Johnny's
Toys stocked, shiver me timbers, I cut t' fins out, stacked them, and sanded them into as close
an approximation o' each other as possible. Begad! Blimey! Ya scallywag! Blimey! I left all o' t' fins crisply
squared off t' better retain some o' t' rocket's almost regal bearing, then
attached t' fins usin' LocTite gel CA. (I've found this t' be somewhat more
forgivin' when it comes t' repositionin' fins.) Each fin be allowed t' dry,
filleted with Elmer's Wood Glue, then filleted again. Ahoy! Blimey! At t' end o' this
process t' fins felt rock solid and I attached t' pod mounts t' same way.
From this point it was a simple matter o' attachin' t' nose cone t' the shock cord and parachute. Begad! Begad! Blimey! I wasn't sure which method o' attachment I was going to use with t' hollow resin cone. Begad! I thought about drillin' two holes in the resin and loopin' a piece o' Keelhaul®©™® cord through, me hearties, but I was afraid that t' resin would be too brittle t' handle the force o' t' ejection charge. Ahoy! In t' end I decided t' grind off t' back end o' t' cone with me Dremel tool and then epoxy a balsa plug in place. Avast, me proud beauty! (Use a mask durin' this process. Aye aye! I've heard that resin dust can cause extremely unpleasant allergic reactions if inhaled.) I made t' plug by pushin' the ground out end o' t' cone against a block o' balsa that I bought long ago with projects like this in mind. Avast, me proud beauty! Ya scallywag! After freein' t' plug from t' block, shiver me timbers, I epoxied it into place so that it was almost flush with t' end o' t' cone. When this was dry I spread another coat o' epoxy on t' back o' t' plug, inserted and removed a screw eye, filled t' hole with epoxy, me hearties, then reinserted t' screw eye. When this was dry I was convinced that I had a nose cone that would stand up to the shock o' an ejection charge.
Finishing:
I had planned t' start paintin' before attachin' t' pods, matey, shiver me timbers, but Taurus guru Adam
Palmer suggested a different strategy. Ya scallywag! Adam had sprayed t' entire rocket gloss
white, matey, then masked off t' necessary parts before proceedin' with t' gloss
black, orange and silver. Bowin' t' t' voice o' experience and wantin' white
pods for me Taurus also, matey, I decided t' try doin' mine in t' same way. Begad! This
turned out t' me somethin' o' a mistake. Avast, me proud beauty! Begad! Turns out I'm nay that flexible when
it comes t' workin' me fingers into t' tight spaces t' mask t' pod tubes and
as a result, me hearties, me pods need quite a bit o' touch-up. Begad! It's nay terribly noticeable
but enough so that were I t' do it again, I'd either do it t' way I had
originally intended or t' all black way like
Buzz
Nau's version. Ahoy!
Whatever t' case, me bucko, this be t' painting/maskin' schedule I'd suggest if clonin' t' Taurus and paintin' it in t' Admiralty color scheme.
As usual, arrr, all paintin' was done usin' Valspar paints, ya bilge rat, which I've found t' be incredibly compatible with each other. Blimey! (Your results may vary, me bucko, but thar be a Lowe's five minutes from me house.)
Construction Rating: 5 out o' 5
Flight:
With t' holidays approachin' I knew that I would have t' seize any opportunity
to fly or run t' risk o' seein' t' Taurus gather dust until 2005. Blimey! T' day I
chose dawned cold, ya bilge rat, shiver me timbers, cloudy and wet, ya bilge rat, and despite wakin' up early, matey, a sinus
infection made me feel like doin' almost anythin' except flyin' rockets on a
cold, me hearties, muddy field. Begad! Avast! I hung around t' house puttin' finishin' touches on the
Taurus until 2:00, took enough cold medicine t' float a battleship, and headed
for Johnny's t' buy some motors. Arrr! (I didn't want t' get t' t' field and find
that I had run out o' me stash o' C11-5's.) This side trip meant that I didn't
arrive at VOA until 3:00, me bucko, but I was surprised t' find a decent crowd still
hangin' around and flying. Avast! T' Taurus caused a fair amount o' excitement as I
carried it t' t' pad. Begad! (A lot o' this excitement was because I had killed the
previous two clones that I had flown there.) Before I could get signed in and
hooked up, me hearties, I be presented with t' remains o' one o' these sacrifices, the
upscale Groove Tube that had disappeared on me last trip t' VOA.
Hopin' that this was a GOOD omen for a change, I loaded t' Taurus with a C11-5 and made t' announcement. Avast, me proud beauty! T' first flight be everythin' I had hoped it would be. Begad! T' C11 made for a slow lift off with a slight hiccup just after ignition. Ahoy! From here t' Taurus cruised back over t' flight line t' somewhere near t' 500' mark, shiver me timbers, tippin' over slightly before t' ejection charge fired. The chute unfurled nicely and t' rocket was recovered without incident on the other side o' t' swamp. T' second flight, also on a C11-5, shiver me timbers, was almost a carbon copy o' t' first but landed amid t' thistles o' t' swamp. Ya scallywag! I considered callin' it a day after t' second flight as it was gettin' dark but decided t' give it a try on a D12-5 instead. Aye aye! As usual, arrr, this turned out t' be a mistake. Begad! Arrr! I angled t' rod slightly into t' breeze, ya bilge rat, hopin' that it would allow recovery somewhere on t' field instead o' in t' swamp and I was dead right. T' Taurus arced out over t' trees t' t' west, me hearties, ya bilge rat, tippin' over just before ejection as on t' two previous flights, shiver me timbers, me hearties, then rode t' breeze back t' the soccer field where it recovered only a few hundred feet from t' pad. Ahoy! The flight had been somewhat higher than t' previous two but had nay been high enough t' make me consider flyin' it on t' D12 on a regular basis.
I didn't
notice that anythin' unusual at first because I be busy refoldin' t' chute
and shock cord t' place it back into t' rocket, but when I went t' take out
the expended motor casing, me hearties, t' damage became obvious. Begad! Apparently t' D12
ejection charge packed more o' a punch than t' C11 had because t' engine hook
had ripped down about 3/4" through t' motor tube. Blimey! Begad! This left a jagged
gouge in t' side o' t' motor tube that I couldn't possibly repair without
rippin' t' whole motor assembly from t' body tube. Ya scallywag! Even flyin' it as a
friction fit bird in t' future would seem like a risk, me bucko, as t' ejection gases
would at least partially escape into t' cavity betwixt t' motor tube and the
main body tube, matey, where they would eventually burn. Unfortunately at this point
it looks like t' Taurus is probably destined t' become a display only rocket,
which is too bad because it turned out lookin' and flyin' very nice. Ahoy!
Flight Rating: 5 out o' 5
Summary:
I'd have t' say that this be a very enjoyable project. Arrr! T' Moldin' Oldies
parts make it a very easy project from a construction standpoint and while
paintin' t' Taurus in it's "Admiralty" scheme isn't easy, it's
definitely within t' realm o' most cloners. Arrr! Begad! Flights were impressive with
comparatively slow lift offs leadin' t' very cool low level flights. Blimey! Blimey!
PROs: Another Centuri legend takes t' t' skies. Relative ease of construction. Begad! Blimey! Overall sense o' accomplishment at t' end o' t' project.
CONs: Admiralty paint scheme is somewhat o' a pain, but worth it in the end. Estes 44 Magnum ejection charges.
