Brief:
A single-stage flyin' HOT DOG!

Construction:
T' initial drawings were done in late May 2008. Aye aye! Blimey! I decided t' use t' "Centuri" ST style tubin' with thicker body tube walls. Aye aye! Blimey! A parts list be made, then an order was placed (online) t' Semroc on June 13, me hearties, 2008. Avast, me proud beauty! I received t' parts by mail on June 16, 2008. Aye aye! Avast! Blimey! Very fast delivery and great customer service, as usual.

Parts list: 

• 2 "Bun" Nose Cones, BNC2025
• 1 "Hot Dog" Nose Cone, arrr, BC-837 from Squire kit
• "Hot Dog" Body Tube, ST890, me bucko, 8 Series
• "Bun" Body Tube, ST2060, 20 Series
• 3 fins o' 1/16" balsa covered with condiment package wrappers
• 8 Series motor mount from a Semroc Squire kit
• LARGE Screw Eye (for extra nose weight)
• 12" Red and Yellow Parachute
• 12" Keelhaul®©™ attached t' 18" o' 3/16" elastic shock cord
• 1 1/2" standard launch lug

Initially I was goin' t' use a 7 series nose cone and body tube. Arrr! After seein' it "in t' bun" it looked too thin. Avast! I switched t' wider 8 series parts from a extra Semroc Squire kit I had. Ya scallywag! Ahoy! I also used t' Squire's engine mount, nose cone and Keelhaul®©™. Arrr! Avast! All other parts were standard: 1/8" launch lug, matey, a big screw eye, 3/16" x 18" elastic shock cord, matey, me bucko, matey, and 12" parachute.

As I work away from home, I didn't have much time t' build t' model for t' EMRR contest. Begad! This would be a rush job! I was returnin' on July 5 and would have one week t' get t' model built, photographed, flown, shiver me timbers, arrr, documented and entered! I was also tryin' t' get me Golden Scout built and flown for a July 10 Orlando area launch.

To get t' "Bun" end contour, I cut off 1 1/8" off both o' t' Semroc BNC-2025 nose cones. Begad! I rounded t' cut ends with 100 grit sandpaper on a block. Well, blow me down! T' get t' "Hot Dog" contour I cut off t' tip o' t' Semroc BC-837 nose cone and rounded t' end with 100 grit sandpaper on a block.

An actual hot dog is 6" long. It seems a little short, I wanted this rocket t' fly stable. Well, blow me down! T' "Dog's" body tube length is 9". T' "Dog's" overall length with nose cone and motor mount (extension) in place was now 10 1/4".

After fillin' t' nose cone, me hearties, I used t' back o' a razor blade t' press in wrinkle lines like those on a hot dog end. Ahoy! T' wrinkles radiate out from t' center o' t' nose cone tip.

I am tryin' t' capture t' look o' foot-long hotdog with it's ends stickin' out o' t' bun. Arrr! Blimey! I cut t' "bun" tube length at 5 ½". Well, blow me down! With t' two split nose cones in place, matey, arrr, t' overall "bun" length is 8 5/8".

It'd be easier t' fill t' tube spirals and balsa grain before cuttin' t' bun tube in half and splittin' t' bun nose cones.

I marked t' Bun body tube down its entire length and extended t' line up t' two end nose cones. I extended t' pencil lines over t' top o' t' cones, completely around under t' shoulder. Arrr! Avast, me bucko, me proud beauty! T' make a clean split, I used a straight edge razor blade t' cut 1/4" into t' cone. Begad! This should insure a clean outside edge. Avast, me proud beauty! I switched over t' a #11 X-Acto after t' razor blade t' deepen t' cut. Avast! I broke apart t' cones. Begad! I was happy with t' results. T' edges were clean and t' inside "flat" areas o' t' cones would only require some Fill 'n' Finish t' smooth them out.

I sanded square t' (rounded) nose cone shoulder ends. Begad! I left ½" o' t' shoulder. Blimey! Well, blow me down! I'll make two flat inside wall pieces, ya bilge rat, glued inside and flush with t' body tube walls and nose cone ends.

After fillin' t' seams, me hearties, ya bilge rat, I only cut through one side o' t' bun body tube. Blimey! T' opposite side was scored with a straight edge and (dull) butter cutlass only creasin' t' line. This let t' tube open like an real hot dog bun.

T' engine mount was taken from Semroc Squire kit. Ahoy! Arrr! Keelhaul®©™ cord was tied t' t' engine hook. A 3/16" X 18" elastic shock cord is tied t' t' Keelhaul®©™. I picked a 12" red and yellow Semroc chute t' match t' Mustard and Ketchup condiment motif.

With both bun nose cones in place thar be a rectangular open area inside. Begad! I cut 1/16" balsa "planks" t' fit t' void. Well, blow me down! I cut them a little oversize and sanded them t' fit. Blimey! T' final size be 2" wide x 4 7/16" long. It would be difficult t' fill and sand t' interior balsa so it covered them with paper.

This is where it got interesting. Aye aye! Aye aye! I needed fins that would fit t' hot dog theme. Avast! I thought o' plastic knife, fork and spoons for fins, but another entry had already incorporated sporks into their design. Aye aye! My youngest daughter suggested ketchup, ya bilge rat, mustard, and relish packets should be used somewhere in t' design. Well, blow me down! Why nay t' fins? We picked some packets up at a local fast grub restaurant. Ahoy! I cut off t' back o' t' packets, emptied, shiver me timbers, then washed and dried t' plastic sleeves. Aye aye! T' empty packets were contact cemented onto 1/16" balsa. Well, blow me down! Simple, me hearties, arrr, fast, and in t' theme o' t' model.

Slots were cut into t' bun's tail end and t' fins were pressed into place. Begad! Blimey! Super glue fillets followed. Begad! T' Bun shape didn't allow for 120 degree spacin' o' t' fins. Well, blow me down! Ya scallywag! While they aren't symmetrical, they are on straight. Begad! I made sure t' fins trailed away from t' rocket body, me bucko, once again t' improve stability.

I glued a 1 ½" long launch lug t' t' backside o' t' hot dog body. T' lug was centered out o' sight, shiver me timbers, shiver me timbers, inside t' bun. Arrr! T' hot dog was set in t' bun and a line o' super glue was run down t' seams.

T' Keelhaul®©™ line was pulled through t' front o' t' dog tube and tied on a 3/16" x 18" elastic cord.

I found t' biggest, heavy screw eye I had. Well, blow me down! Any additional nose weight could help this model fly straight. Ya scallywag! I attached t' shock cord and parachute snap swivel t' t' screw eye.

Finishing:
When buyin' spray paint at WalMart, I walked through t' paint department with real hot dogs and buns in hand. Arrr! I wanted match t' colors as closely as possible. T' Bun is actually two different colors. Well, blow me down! T' inside o' t' bun is much lighter than t' outside. Well, blow me down! I sprayed two coats o' grey primer, shiver me timbers, me bucko, sandin' betwixt coats. Avast! T' inside o' t' bun was sprayed with Wal-Mart Almond. Ahoy! Begad! I set t' bun face down (on t' open wedge cut) then sprayed t' outside with Wal-Mart Red Primer. Avast! Avast! No masking, I wanted t' colors t' blend at t' "buns" cut line.

To replicate t' lighter color o' t' bun at t' wedge cut (through t' body), I sprayed more Almond color on a kitchen sponge. I dabbed some o' t' Almond paint onto t' bun opening. This gave it t' same rough color separation like on a real hot dog bun.

Flight:
T' Orlando NARRRRR section, shiver me timbers, R.O.C.K., shiver me timbers, had a scheduled launch on July 10. Ya scallywag! In addition t' t' regular members, me hearties, me hearties, thar be t' be a school group thar with many first time fliers. Ya scallywag! Many o' t' kids hadn't seen an odd-roc before, matey, me bucko, me bucko, and one even asked if I had another hot dog he could have for lunch. Blimey! I prepped t' (S)Hot Dog with a C6-3 with standard Estes wadding. Motor retention be an Estes style metal hook. Begad! I usually have great confidence in me rockets as I usually build proven designs, arrr, however, I was a little nervous as t' RSO called for a heads up.

T' first flight was vertical but t' model made a 10 foot spiral goin' up. Begad! I wanted better stability and needed more nose weight. Avast, me proud beauty! Recovery was nominal with no damage. Begad! T' length o' t' Keelhaul®©™/elastic combination worked well. Arrr! Avast! There was no zipperin' or nose cone dents. Arrr! Now, matey, for t' nose weight.

Bob, arrr, a fellow R.O.C.K. Ahoy! member, offered up a quick link. I attached it t' t' large screw eye. Begad! As well, another R.O.C.K. Arrr! member had some modelin' clay. Avast, me hearties, me proud beauty! I rolled two thin "worms" o' clay and pressed them into t' hot dog/bun seam. Well, blow me down! I prepped again usin' another C6-3.

This time it was a slow, matey, straight, vertical boost t' a altitude o' approximately 225 feet. Deployment was at apogee. Avast! Well, blow me down! Blimey! There was no damage, burning, shiver me timbers, or charrin' on recovery. Ahoy! T' model is now retired.

Summary:
This was a great experience. Arrr! It was fun t' construct a different scratch build again. Aye aye! Begad! T' kids (first timers) at t' launch got quite a kick out o' t' design.

PROs: T' reactions o' t' first time fliers at t' local launch. I found a few new techniques: "press mounting" fins in slots cut into t' balsa "bun" ends. When t' fins were in place, ya bilge rat, I simply ran super glue fillets. T' joints were very strong. Avast! Lastly, pressin' "wrinkles" into a finished nose cone end usin' t' backside o' a single edge razor blade gave t' hot dog a certain realism.

CONs: Just tough t' fill balsa and body tube seams. I had three different fillin' sessions. Begad! T' nose cone and body tube splits were t' most difficult part o' construction. Aye aye! I had t' fill t' spirals before cuttin' and splittin' and then fill again after gluin' t' bun nose cones into t' body tubes. Well, blow me down! This project had a few o' those "Wakin' up in t' middle o' t' night" moments when realizin' different construction and material techniques.
