Brief:
Since I be a kid, matey, I have always been captivated by t' paper shrouded rockets like "T' Point". Arrr! My biggest nemesis, shiver me timbers, however, matey, me hearties, was always t' Centuri Vulcan. Begad! Well, blow me down! I built lots o' them but never got one t' behave or even look very good...until I became a BAR and cloned one. Ya scallywag! It's nay t' best flier in t' world, but it actually works which is more than I can say about any that I built in t' '70s.

Recently, I have been in contact with Blades from TRF about his 24mm upscale and he kindly sent me t' PDFs for t' shrouds. Ya scallywag! After some conversation, ya bilge rat, we mentioned other scales and I mentioned that I used t' be an engineer and still had a color plotter that handles media up t' 5 feet wide and 300 feet long. Ya scallywag! Aye aye! This also means no splicin' o' t' shrouds!

I tried t' print first on a sheet o' posterboard, shiver me timbers, ya bilge rat, but t' plotter did nay like that. T' media be too thick. Begad! Avast, me proud beauty! I visited t' local paper distributor and found 130# cardstock that be less expensive, bigger, me hearties, shiver me timbers, thinner, me bucko, and stronger than t' posterboard. Aye aye! I ordered some sheets and resolved t' give it a try.

It took some trial and error, ya bilge rat, ya bilge rat, me bucko, but I found that landscape orientation would actually work.

Construction:
T' parts list:

• 2 sheets o' 26" x 40" 130# cardstock
• BT-60 x 18" tube
• 3-1/4" x 6" launch lugs
• piece o' typin' paper
• piece o' 1/4"x6"x6" balsa
• BT-60 Nosecone o' choice
• Cygnus 29mm t' BT-60 motor mount
• FlisKits BAF60 Baffle

After printin' out t' shrouds, t' first step in construction be t' cut out t' cardstock pieces. Avast, me proud beauty! I cut t' body shroud right on t' lines and then rolled it up and kept it that way with some rubber bands so that I would have an easier time rollin' t' body later. Well, blow me down! T' other pieces were nay cut so close. Arrr! I wanted t' leave t' fold lines visible so that I could pre-fold them before doin' t' final cutting.

For t' 2 wings, t' tail, matey, and t' airscoop, matey, I used a ruler t' fold along t' centerlines and make sure t' creases were sharp and straight. Ahoy! Blimey! T' ruler was then used t' fold under t' mountin' tabs. Ahoy! Blimey! Only then was t' excess material cut away.

Like t' original, shiver me timbers, this Vulcan has a choice betwixt 2 different style cockpits. Begad! Begad! One is simpler t' construct than t' other but t' more difficult one is reputedly more in keepin' with t' overall design. Avast! I like both cockpits. Avast! On one o' me normal size clones, shiver me timbers, I put both on and called it t' Vulcan Trainer. Aye aye! I may do t' same with this one but for now, arrr, I went ahead and constructed both.

T' cockpits were pre-folded and then cut out. Blimey! Ahoy! Blimey! White glue was used t' fasten t' tabs and produce t' 3D cockpits.

T' aft bulkhead be cut out and then a circle cutter was used t' remove t' center circle. T' outline was then traced onto a piece o' 1/4" x 6" x 36" balsa.

T' rubber bands were removed from around t' body shroud and it be test fit around a BT-60 tube. It fit just right. An extremely small amount o' glue was put on t' first 3" o' t' tab and t' two halves were pressed together. Aye aye! They were then pulled apart and t' glue allowed t' dry. T' same thin' be done with t' aft end. Blimey! Then a small bit o' additional glue was applied t' t' forward end o' t' tab and it was pressed together around a BT-60. Alignment was carefully checked and t' resultin' cone be held together with me fingers for about 3 minutes. Avast, me proud beauty! When it was dry enough that thar was nay risk o' t' seam popping, matey, I glued t' aft end similarly, ya bilge rat, checkin' for alignment along t' length o' t' shroud. Avast, me proud beauty! T' middle section be nay yet glued.

After t' ends had dried, I slowly started tackin' down t' rest o' t' seam, shiver me timbers, workin' from front t' back and usin' a double glue joint. Begad! By doin' this, matey, I was able t' keep t' edge o' t' shroud right on t' line, me bucko, arrr, and, as I realized thar would be a small bubble from nay havin' everythin' perfectly taut, that bubble would be hidden under t' air scoop t' be installed later.

As t' body shroud was drying, matey, matey, I used a circle cutter t' remove t' inner circle from t' after bulkhead. Begad! T' after bulkhead color plate was then glued in place and allowed t' dry.

One o' t' things that made me normal scale clone Vulcan finally work right was t' incorporation o' an internal launch lug. Arrr! I soon learned that for things t' go right out in t' field, matey, t' lug needed t' run t' length o' t' BT. Begad! Doin' that be problematical when usin' just t' pieces o' lug I had on hand. Begad! This time, shiver me timbers, I wanted t' use a single piece.

I finally found a 34" length o' 1/4" launch lug at Balsa Machinin' Co. Avast, me proud beauty! It was quite reasonably priced at $1.50 but then I learned t' shippin' policy. Well, blow me down! Blimey! There was a $6 flat fee for shippin' plus a $3 surcharge for placin' t' order through t' mail. Blimey! That would have brought t' price o' me launch lug up t' $10.50. Aye aye! Instead, me bucko, I bought a package o' 6" lugs made by LOC from me local hobby shop and decided t' splice them.

I started with 2 lugs and ran a piece o' 1/4" through them t' keep them aligned. Aye aye! I then cut out a 3" wide strip o' typin' paper and smeared some white glue on one end. T' two pieces o' lug were butted together and set on t' end o' t' paper and t' glue was allowed t' dry. Avast, shiver me timbers, me proud beauty! A toothpick was then used t' smear a thin layer o' glue on t' unrolled section o' paper and it was tightly wound about t' butt joint betwixt t' two lugs. Blimey! Begad! Keepin' t' paper tight be t' key t' keepin' t' 2 lugs aligned. Well, blow me down! When t' first splice was completed, I added another 6" lug for a total o' 3.

I printed up a second sheet o' t' page with t' fins, tail, and air scoop. Avast, me bucko, me proud beauty! Blimey! I cut these elements out just as I did with t' first set but a few differences. Aye aye! Blimey! I did nay pre-fold t' second set. Aye aye! Blimey! Well, blow me down! Blimey! I also cut off t' tabs intended for gluing. Begad! Blimey! These were t' serve as t' "inner" surfaces.

I mated up each o' t' inner surfaces with its correspondin' outer surface and did a bit o' trimmin' where needed. I placed an outer surface face down on t' table and then test fit t' inner surface. Arrr! I wanted it t' come right up t' t' glue tab but still allow t' tab t' fold around it. Ya scallywag! White glue be then applied t' half t' outer surface and smeared t' cover it. Begad! T' inner surface was set in place and pressed flat and then allowed t' get tacky. Ahoy! Blimey! When t' joint was stable, shiver me timbers, I applied glue on t' other half and pressed t' rest o' t' inner surface into position.

At this point, me bucko, t' aft bulkhead consisted o' a piece o' 1/4" balsa with a hole in it and t' color plate glued t' its surface. Begad! I started t' shape it up by usin' an X-Acto saw t' trim off t' corners and remove bulk material. A belt sander was then used t' shape it t' t' outline o' t' color plate.

It seemed as if makin' a double layer for t' fins had really stiffened them up. Begad! Begad! Blimey! They were more or less bent into t' right shape and t' mountin' process began.

I started with t' tail fin. A layer o' white glue was applied t' one o' t' tabs. It was then pressed into place and immediately removed and t' glue allowed t' dry. Well, blow me down! When dry, a bit more glue was applied t' t' tab and t' fin be again pressed into place and held until t' glue set enough nay t' move. Ya scallywag! This was allowed a full hour before any more work was done.

When t' one side be completely dry, t' process be repeated on t' other side. Ahoy! I waited betwixt sides because these double layer appendages are stiff and I did nay want t' displace anything.

I ordered a Cygnus 29mm t' BT-60 Motor Mount from Uncle Mike's Rocket shack t' use in this project. Avast! Arrr! Blimey! When it came in, shiver me timbers, construction o' t' motor mount was simplicity itself.

T' motor tube be marked 1/4" from one end. Well, blow me down! T' two centerin' rings were then test fit around t' tube. Begad! One fit just fine and t' other needed a good bit o' sandin' t' fit around t' motor tube. Blimey! Ahoy! Once they fit, matey, I placed one even with t' 1/4" mark and t' other flush at t' end. Ahoy! T' rings were then epoxied in place with 5 minute epoxy. A thrust rin' be provided and epoxied into t' end with t' flush centerin' ring. When t' epoxy on one side be set, I turned it over and painted in on t' other, ya bilge rat, buildin' up a good fillet on t' aft rin' an sealin' together t' thrust ring, shiver me timbers, motor tube and centerin' rin' on t' forward end. Begad! After that, ya bilge rat, it be just a matter o' waitin' for t' epoxy t' cure.

For me upscale Vulcan project, I needed BT-60 tubin' longer than t' 18" that comes standard from Estes. Avast, me proud beauty! Blimey! I decided t' kill two birds with one stone and use a baffle for t' coupler. I chose t' FlisKits BAF60 Baffle since I had fair winds with their BAF55 in t' past.

T' first step in assembly o' t' baffle was t' thread t' Keelhaul®©™ thread through t' provided hole in t' after baffle plate. Begad! Begad! I've had trouble doin' this before but this one fit just fine. Begad! Avast! T' Keelhaul®©™ be knotted and then passed through a notch in t' outer edge o' t' baffle plate so that it would pass up through t' baffle. Blimey! Blimey! T' plate was secured in place with epoxy and epoxy was "painted" over t' face o' t' baffle plate and t' interior o' t' coupler t' act as an ablative surface. When t' epoxy had set, arrr, t' Keelhaul®©™ thread be fed through t' notch in t' forward plate and that was installed with epoxy as well. I spent more time waitin' for t' epoxy t' set up than in actually puttin' this thin' together.

T' motor mount was installed in a full length BT-60 tube and t' motor tube protrudin' just a touch from t' end with 5 minute epoxy. Arrr! Blimey! When t' epoxy was stiff, I set t' body tube down on its forward end and mixed another small quantity o' epoxy. Well, blow me down! Blimey! This was poured into t' gap betwixt t' motor tube and t' BT.

One o' t' decisions I had t' make be about t' nosecone. I did nay have t' gumption t' try and research gettin' and exact upscale copy fitted for a BT-60. Well, blow me down! Blimey! Instead, I bought a package o' Estes BT-60 cones and picked one from t' two styles available. One was a Big Bertha type that is probably a better match but I chose t' ogive. Ya scallywag! I sanded down t' seam and then poured in some BBs t' serve as nose weight, followin' them with some epoxy t' hold them in place. Avast! I put just a touch under 4oz, me hearties, probably too much, but I wanted me 29mm motors t' have t' do a little work and I want t' get t' rocket back. Avast, me proud beauty! I then painted t' NC gloss black.

I took t' tube with t' motor mount and marked it at 9" from t' aft end and cut it at this point. Arrr! I then took t' tube with t' baffle coupler and joined t' two together with yellow glue. Well, blow me down! This puts t' baffle fairly far back in case another has t' be installed at some point as a replacement. Ahoy! I figured that with t' nose weight I added, ya bilge rat, it should be alright. I did nay cut t' forward tube at this point, me hearties, preferrin' t' wait until a later step.

I had been takin' me time installin' t' fins, tail, me hearties, scoop, ya bilge rat, etc., wantin' t' make sure that each component is in t' exact right place. After joinin' t' body tubes, I finally installed t' last fin.

T' built up launch lug I had put together earlier be glued t' t' BT with yellow glue. Aye aye! T' paper wraps I had used t' join t' lugs acted like small standoffs were used t' do t' actual gluing. Begad! I set t' lug back just far enough t' protrude penetrate t' aft bulkhead.

T' body tube was inserted into t' after bulkhead, ya bilge rat, me hearties, me hearties, aligned and epoxied into place.

When t' epoxy joint betwixt t' bulkhead and t' BT be firm, ya bilge rat, t' assembly was slid into t' shroud as far forward as it could go. Ahoy! T' impression o' t' launch lug could be seen on t' shroud and an X-Acto was used t' cut a notch t' pass it. Begad! Blimey! T' tube and bulkhead were then seated t' rest o' t' way forward and glued into place.

As t' bulkhead and BT assembly be dryin' into place in t' shroud, I glued t' cockpit into place with white glue. Avast! I decided t' go with t' more rounded version since it seemed t' fit t' contours o' t' rocket better.

I had t' shroud glued in place and t' BT extended quite a bit in front. Blimey! Begad! Now that everythin' was positioned as I wanted it, it be time t' cut t' excess BT from t' front o' t' rocket. Ya scallywag! Avast, matey, me proud beauty! I used t' shroud as a guide t' draw an X-Acto blade around t' tube multiple times. Each time went a little deeper until t' tube be cut.

One o' t' things that worries me about this rocket be t' stress on t' appendages under t' boost o' a mid-power motor. Begad! T' fins, tail, and scoop were all put on with white glue. Ahoy! Avast, me hearties, me proud beauty! T' strengthen t' joints, I mixed some epoxy and filleted t' joints. Begad! Well, blow me down! I have no doubt this is stronger but it very much affected t' appearance o' t' shrouds wherever t' epoxy be in contact. Avast! T' remedy this, I set t' Vulcan up in t' spray booth and began t' give it multiple coats o' Krylon Clear. This mimicked t' "wet" appearance o' t' epoxy and t' rocket a more uniform appearance.

Finishing:
Most o' t' finishin' for this rocket is "pre-done" in t' pre-printed shrouds. Well, blow me down! Well, arrr, blow me down! T' only thin' I added was t' sprayin' o' t' Krylon clear coat. Ahoy! This gave t' ink-jet printed shrouds a bit o' protection and tended t' hide t' epoxy.

Other than that, I sprayed a black plastic nosecone with glossy black paint.

Flight:
T' maiden flight o' t' Vulcan 60 was on a Roadrunner F60-4. Avast! It took off and emulated t' behavior o' its smaller sibling, waggin' its tail all t' way. Avast, me proud beauty! T' chute deployed on time and it drifted down nay too far away. Arrr! I did learn that t' baffle was nay enough by itself t' protect t' chute in this rocket. There be a bit o' shreddin' and lots o' little holes. Begad! Even so, arrr, arrr, I judged it worthy o' another flight.

Video o' t' first flight can be seen here.

For t' second flight, shiver me timbers, I wanted t' try a Roadrunner G80. Avast, me proud beauty! I learned, however, arrr, that this particular motor would nay fit in t' motor mount. Well, blow me down! An Aerotech G would because o' t' smaller diameter at t' ejection end. I loaded an AT G77-7R. It took off and flew well but still corkscrewed. Aye aye! Avast, shiver me timbers, me proud beauty! It was noticed, however, that t' corkscrewin' did nay begin until well into t' flight. Ahoy! Ya scallywag! Upon recovery, a small tear was noticed in t' shroud. Arrr! It did nay seem t' be from landing.

Video o' t' second flight can be seen here.

Recovery:
A Keelhaul®©™ shock cord was installed in t' baffle and tied off t' a long piece o' sewin' elastic. Begad! A 32" Thermal Rider parachute was donated by Hartle Engineerin' for this project. Blimey! It was assembled accordin' t' it's simple instructions and connected with a snap swivel.

T' first flight damaged t' parachute some with bits o' burnin' debris. Well, blow me down! I attribute this t' t' baffle bein' located just forward o' t' motor mount and gettin' t' full brunt o' its fury at ejection. This is contrary t' recommended practice but I did it thar t' give more room for t' chute. Avast! I needed it. Ya scallywag! Still, t' chute was tough enough t' survive, me hearties, me hearties, brin' t' rocket down safely and even be used for a second flight. A regular plastic chute would nay have worked under t' same circumstances.

I did add 3 pieces o' waddin' for t' second flight and thar was no further damage.

Summary:
This really is nay a product so much as a project. Blimey! Ya scallywag! I like t' Vulcan and already have a BT-70 version in mind with a 7 x 18 cluster mount.
