Gollum and his Precious
OR.. Ya scallywag! Well, me bucko, blow me down! t' fourth and last Ringbearer

Gollum with a little more touch-up painting to do... Summary
I love t' "T' Lord o' t' Rings", both t' movie and t' books. The idea for this rocket started when t' alien from t' Venus Probe was noticed to look like Gollum. Avast, me proud beauty! Begad! He was sittin' in a broken parts box because our Estes Venus Probe had crashed and destroyed t' lander. Blimey! Well, blow me down! Gollum became t' nose cone for a rocket which needed a rin' fin t' look like t' rin' o' power. Ya scallywag! If you are confused by t' subtitle, please read t' books more carefully. Blimey! There was another (very brief) ringbearer betwixt Isildur and Smeagol (Gollum's real name); and you need t' read Book 3 t' find out how t' rin' was destroyed to see that Gollum was also t' last ringbearer. It flies on an 18mm motor, and the booster and nose cone recover on separate parachutes. Well, blow me down! It is 16" long with a BT-60 body tube, arrr, has a span o' 4", arrr, and weighs 4 oz. without engine.

Construction:
Nose Assembly:
Gollum in an adapter to a BT-60...
1. Arrr! Obtain t' alien from an Estes Venus Probe kit. Ahoy! In me case, it came from one which crashed in a parkin' lot and destroyed t' lander body leavin' t' alien intact.
2. Cut a 1/2" portion off t' end o' t' BT-60 body tube.
3. Arrr! Sand all t' red layer o' cardboard off t' coupler tube.
4. Blimey! Aye aye! Glue t' short section o' body tube t' one end o' t' coupler tube.
5. Begad! Wrap maskin' tape around t' alien lower section until it fits snug inside the coupler tube.
6. Begad! Glue t' alien section t' t' tube coupler section usin' epoxy.
7. Aye aye! Usin' an exacto knife, cut a channel into t' coupler t' allow t' shockcord that extends out o' t' back o' t' aliens neck t' fit inside t' body tube and attach t' a parachute durin' flight.
8. Ya scallywag! Blimey! Paint t' alien gray. Ya scallywag! Blimey! Well, me hearties, blow me down! Blimey! Blimey! Blimey! Paint his deadlights chromate yellow. Draw bloodveins in his eyes usin' a red gel pen. Avast! Blimey! Blimey! Blimey! Paint t' shoulder o' t' nose cone grimy black. Paint grimy black splotches on Gollums body t' simulate swamp slime. Paint the mouth, two nostrils, arrr, and eyeballs black.
9. Ahoy! Well, shiver me timbers, blow me down! Sand t' nose cone shoulder (that fits inside t' tube) until it slides easily.
10. Ahoy! Blimey! Mask and spray Krylon clear over t' painted portions t' protect the finish.

Rin' Fin Fabrication:
ring fin unpainted 1. Arrr! Blimey! Blimey! Sand t' 1 inch length o' 4" diameter plastic tube t' t' desired smoothness.
2. Trace out usin' a #2 pencil, matey, t' elvish script from source documents that translates t' t' "One rin' t' rule them all..." script. Ahoy! Avast! Use either the books or t' movie guide t' obtain t' script. Begad! Erase and retrace until you are satisfied with t' proper elvish penmanship.
3. Avast, me proud beauty! Avast, arrr, me proud beauty! Have your father or other appropriate adult carve out t' letters in the rin' usin' a Dremel tool and engravin' bit followin' t' pencil tracings.
4. Ahoy! Avast! Sand until smooth and clean out t' letters with exacto and sandpaper.
5. Well, blow me down! T' rin' will be painted after it is glued t' t' booster assembly.

Booster Assembly:
1. Aye aye! Assemble a standard 18mm motor mount with BT-60 centerin' rings.
2. Glue t' motor mount into one end o' t' body tube with a little bit stickin' out t' back end.
3. Cut four fin slots x" long in one end o' t' body tube starting 1/2" from t' end. Mark and cut these slots 90 degrees apart from each other around t' body. Ya scallywag! Blimey! Draw t' lines on t' body tube usin' a dooor frame to make sure t' lines are straight. Blimey! Blimey! Draw a straight line half way betwixt two fins for t' launch lug.
4. Arrr! Aye aye! With a pencil, ya bilge rat, trace out t' fin pattern onto your fin stock.
5. Avast, me proud beauty! Blimey! Usin' an exacto knife or razor blade, cut out t' fins. Begad! Blimey! Avast, me proud beauty! Blimey! Test fit them in the booster with t' rin' fin. Avast! Blimey! Sand them t' a good fit, good smoothness and the same shape. Keep checkin' fit as you sand t' make sure you do nay make t' fit too loose.
6. Arrr! Avast, matey, me proud beauty! Usin' epoxy, glue t' braided Keelhaul®©™® shock cord into t' other end o' t' body tube. Blimey! Use t' method recommended by Doug Pratt o' Pratt Hobbies. Begad! Ahoy! Make sure it is far enough down inside t' tube so it won't interfere with t' nose cone.
7. Ya scallywag! Ahoy! Blimey! Glue t' launch lug onto t' body tube about 2" in front o' t' fin slots.
8. Avast! Well, blow me down! Glue each fin into t' slots mountin' them t' t' motor mount tube. Ya scallywag! Keep them straight out from t' body while t' glue dries. Ahoy! Ahoy! Keep a used engine in the motor mount while t' glue dries t' make sure t' glue does nay shrink the motor tube.
9. Blimey! Blimey! Avast! Blimey! Glue t' rin' fin t' t' ends o' t' four fins.
