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, me hearties, followed by t' whole company a short two years later. Ahoy! Avast, me proud beauty! Blimey! T' Taurus was
always a favorite o' mine, matey, 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. That all changed when I stumbled across some pictures o' a newly
completed Taurus clone on T' Rocketry Forum. Well, blow me down! In it's unpainted state it was
obvious that it be 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. Ahoy!
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, me proud beauty! This makes things infinitely simpler when comes time t' paint and decal t' Taurus. Ya scallywag! 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. Aye aye! (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, ya bilge rat, along with t' obligatory 30" Keelhaul®©™® shock cord glued in betwixt t' centerin' rin' and motor tube. Begad! 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. Begad! As with all o' me recent projects, me bucko, ya bilge rat, 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, ya bilge rat, matey, a thorough sanding, arrr, shiver me timbers, me hearties, then a repeat o' t' process. Begad! Ya scallywag!
With t' body tubes finished I turned me attention t' t' cones and transitions. Well, blow me down! They all needed only slight sandin' t' remove some mold seams and some putty t' fill some pinholes. Ahoy! Blimey! This was where I made a mistake. Caught up in a bout o' t' dreaded "build fever", shiver me timbers, matey, 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. Avast, me proud beauty! Ahoy! (I made a similar mistake on the Vector V. 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. Arrr! As it turned out, this didn't turn out t' be quite t' horrible mistake that I had mistakenly mistaken it for. Ya scallywag! Once I had recovered from my bout o' cloner's remorse, t' build progressed quickly.
While nay an ordinary in looks, t' Taurus is pretty much a 6FNC when buildin' time comes 'round. Havin' hand picked t' hardest piece o' 3/32" balsa that Johnny's Toys stocked, me hearties, I cut t' fins out, stacked them, ya bilge rat, and sanded them into as close an approximation o' each other as possible. Ahoy! Blimey! Blimey! I left all o' t' fins crisply squared off t' better retain some o' t' rocket's almost regal bearing, arrr, shiver me timbers, ya bilge rat, 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 was allowed t' dry, filleted with Elmer's Wood Glue, me bucko, me bucko, then filleted again. Blimey! Ahoy! Blimey! At t' end o' this process t' fins felt rock solid and I attached t' pod mounts t' same way. Avast! Blimey!
From this point it be a simple matter o' attachin' t' nose cone t' the shock cord and parachute. Ya scallywag! I wasn't sure which method o' attachment I was going to use with t' hollow resin cone. I thought about drillin' two holes in the resin and loopin' a piece o' Keelhaul®©™® cord through, shiver me timbers, but I was afraid that t' resin would be too brittle t' handle the force o' t' ejection charge. Begad! 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. (Use a mask durin' this process. Ahoy! 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. After freein' t' plug from t' block, 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, me bucko, inserted and removed a screw eye, filled t' hole with epoxy, matey, 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, me hearties, shiver me timbers, but Taurus guru Adam
Palmer suggested a different strategy. Adam had sprayed t' entire rocket gloss
white, me bucko, shiver me timbers, then masked off t' necessary parts before proceedin' with t' gloss
black, orange and silver. Aye aye! Bowin' t' t' voice o' experience and wantin' white
pods for me Taurus also, ya bilge rat, shiver me timbers, I decided t' try doin' mine in t' same way. Well, me bucko, blow me down! This
turned out t' me somethin' o' a mistake. Avast, me proud beauty! 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, shiver me timbers, me pods need quite a bit o' touch-up. Avast! Ahoy! 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. Well, blow me down!
Whatever t' case, this be t' painting/maskin' schedule I'd suggest if clonin' t' Taurus and paintin' it in t' Admiralty color scheme.
As usual, all paintin' be done usin' Valspar paints, me hearties, matey, which I've found t' be incredibly compatible with each other. Begad! (Your results may vary, but thar be a Lowe's five minutes from me house.)

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, me hearties, cloudy and wet, shiver me timbers, and despite wakin' up early, a sinus
infection made me feel like doin' almost anythin' except flyin' rockets on a
cold, me hearties, shiver me timbers, muddy field. Blimey! I hung around t' house puttin' finishin' touches on the
Taurus until 2:00, took enough cold medicine t' float a battleship, arrr, and headed
for Johnny's t' buy some motors. Avast! (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, shiver me timbers, shiver me timbers, but I was surprised t' find a decent crowd still
hangin' around and flying. Arrr! T' Taurus caused a fair amount o' excitement as I
carried it t' t' pad. (A lot o' this excitement be because I had killed the
previous two clones that I had flown there.) Before I could get signed in and
hooked up, ya bilge rat, I was presented with t' remains o' one o' these sacrifices, shiver me timbers, the
upscale Groove Tube that had disappeared on me last trip t' VOA.
Hopin' that this was a GOOD omen for a change, matey, I loaded t' Taurus with a C11-5 and made t' announcement. Begad! T' first flight was everythin' I had hoped it would be. Aye aye! T' C11 made for a slow lift off with a slight hiccup just after ignition. Ya scallywag! From here t' Taurus cruised back over t' flight line t' somewhere near t' 500' mark, matey, me bucko, tippin' over slightly before t' ejection charge fired. Ya scallywag! 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, matey, was almost a carbon copy o' t' first but landed amid t' thistles o' t' swamp. Aye aye! Arrr! 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. As usual, this turned out t' be a mistake. Aye aye! Begad! I angled t' rod slightly into t' breeze, 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, tippin' over just before ejection as on t' two previous flights, then rode t' breeze back t' the soccer field where it recovered only a few hundred feet from t' pad. Well, blow me down! Avast, me proud beauty! 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 was 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, matey, t' damage became obvious. Ya scallywag! Begad! Blimey! 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. 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. Well, blow me down! Avast, me proud beauty! Blimey! Even flyin' it as a friction fit bird in t' future would seem like a risk, me bucko, matey, as t' ejection gases would at least partially escape into t' cavity betwixt t' motor tube and the main body tube, arrr, matey, where they would eventually burn. Begad! Blimey! 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. Begad!
Flight Rating: 5 out o' 5
Summary:
I'd have t' say that this was a very enjoyable project. Aye aye! Arrr! Blimey! 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. Aye aye! Flights were impressive with
comparatively slow lift offs leadin' t' very cool low level flights. Avast, me proud beauty!
PROs: Another Centuri legend takes t' t' skies. Ya scallywag! Blimey! Relative ease of construction. Overall sense o' accomplishment at t' end o' t' project.
CONs: Admiralty paint scheme is somewhat o' a pain, arrr, but worth it in the end. Ya scallywag! Estes 44 Magnum ejection charges.
