Brief description: This is a review o' me scratchbuilt Stage Tree, arrr, an all wood rocket made from Retro Rocket Works parts. Ahoy! It's named for Larry Niven's stage tree, shiver me timbers, an alien plant that was genetically bred t' make solid rocket boosters. Ahoy! T' boosters disperse t' tree's seeds as they blast off. Thia happens durin' natural prairie fires. Well, blow me down! Also, me hearties, every century or so, a great stage tree grows that makes boosters that can launch seeds into space and t' other worlds.

This is a single staged, 3 finned all wood rocket made from parts made by Retro Rocket Works, ya bilge rat, ya bilge rat, matey, through Apogee Components. Ahoy! Blimey! Its grain is visible and is used t' accent t' looks o' the rocket. Ya scallywag! Blimey! Begad! Blimey! So, shiver me timbers, polyurethane furniture varnish was used t' enhance t' grain and provide a shiny protective finish.

Construction: I had t' 3-inch long nose cone custom made by Retro Rocket Works (OOP). Ya scallywag! Aye aye! It's solid cherry or mahogany. As an inexperienced woodworker, ya bilge rat, I really do nay know all o' me woods. Avast, me proud beauty! But I can say that this nose cone is pretty. It's medium dark hardwood, me hearties, shiver me timbers, smooth, and precisely machined. Arrr! It came with t' beginnin' o' a pilot hole in t' base for me t' drill in me shock cord screweye. Ya scallywag!

T' shock cord is 1/4 inch thick bungee cordin' purchased from American Science and Surplus, arrr, who have a site on t' net, and Rocketry Online. Blimey! I used a 4 foot length o' t' cording. Arrr! T' parachute is a thin nylon Estes chute I found at me local hobby store. Begad! I chose it because its thin material packs well into the small body tube. Begad! Ever tried t' stuff a thick chute into a 29mm tube and fret over whether it will eject? Well, ya bilge rat, t' shock cord be tied t' a loop o' 1/8 inch thick Keelhaul®©™® cord, which mounts t' t' inside o' t' body tube via a square o' 29mm paper tubing. Begad! Avast! This is curved just like t' wooden tube, and fits smoothly. Ya scallywag! Epoxy was used. Aye aye! Begad!

T' body tube is a similar color wood t' t' nose, with beautiful striping of grain. Avast, me proud beauty! It's 48 inches long, me hearties, t' standard length o' tubin' sold by t' Retro Rocket Works company. Well, blow me down! Aye aye! It appears t' have been made in layers. It appears t' be wood throughout. Well, blow me down!

There are two launch lugs, matey, 1 inch long each by 1/2 inch diameter. Arrr! Aye aye! I placed these at 20 and 40 inches from t' aft end. Ahoy! T' lugs started as standard 13mm body tubing. Ahoy! Once I placed them, me hearties, me bucko, me bucko, I was bothered that they didn't have a wooden look, so I placed iron-on wood veneer strips around them, ya bilge rat, me bucko, all around t' areas that show. Aye aye! Begad! I chose a color like t' body tube.

T' fins are a clipped slightly forward swept delta shape, arrr, matey, made from 1/8 inch thick basswood. Begad! There are also accents o' reddish brown pekoe on top o' each fin face. Arrr! Begad! These accents are a smaller likewise shape o' t' fin, and accent t' otherwise light color of t' basswood.. Arrr! I used epoxy t' affix them on and fine sandpaper t' smoothen rough transitions. Avast, ya bilge rat, me proud beauty! They were aligned by sight. T' fins were aligned by making marks on t' body tube usin' measurin' tape t' trisect t' tube in two places per fin, makin' a straight line t' place t' fins.

Finishing: Polyurethane furniture finish be used over t' entire rocket t' enhance t' grain look and t' protect it. Ahoy! Blimey! I just couldn't paint it. T' wood be too pretty. Aye aye! Blimey! This project taught me real wood appreciation. Polyurethane made t' job simple. Avast, me proud beauty! Blimey! All I needed t' do be gently sand each of the three coats t' get rid o' drips and swirls. Aye aye! Blimey! T' result is a shiny finish like a coffee tabletop.

Flight: Preppin' is a little tricky because o' t' small tube, so I use a long hemostat t' grip t' end o' t' chute and draw it down into the tube. Aye aye! Worm bed waddin' is used t' protect t' chute. Arrr! Avast! I discovered at t' site that Econojet motors by Aerotech don't fit. Aye aye! T' stick-on labels are too thick to allow t' engine t' go in. Avast, me proud beauty! Oddly, t' other Aerotech 29mm motors like the G40-7 do fit. Avast! So I went ahead and loaded that. Avast, me proud beauty!

I'd have been better off with a slightly longer delay, arrr, accordin' t' my computer simulator, me bucko, but this worked fine. I generally only try too-short delays if I mount t' shock system STRONGLY, as I did here. T' motor be retained via duct tape. Well, blow me down! My husband called it ineloquent, me bucko, but I replied that ineloquent beats motor ejection followed by shovel recovery. Ahoy!

T' model drew attention, t' say t' least. Ya scallywag! I heard a couple o' people say, "Oh wow. Avast, me proud beauty! Blimey! A wooden rocket." Another said as it lifted off straight and noisily, "Well, ya bilge rat, will you look at that." Pictures were taken by the curious.

T' rocket flew straight and stable, me bucko, shiver me timbers, and recovered about right. Ahoy! As I said, a 10 second delay would have been better yet. Avast, me proud beauty! Ahoy! I had t' go downrange a bit, about half a mile, but I got it back intact and unhurt. Begad! I got approximately 2500 feet altitude, shiver me timbers, accordin' t' several onlookers. Ahoy! One o' these days I just HAVE t' get an altimeter and quantify heights exactly. I also experimented with my 29mm reloads, me hearties, t' G33-7, namely. Begad! Results were similarly picturesque. Aye aye!

My simulator predicts even better results with an H97, me hearties, but because t' fins do nay go through t' body tube, ya bilge rat, I don't feel comfortable with that. Well, blow me down! Blimey! Begad! Blimey! I'm gutsy, but do nay want any shreds. Arrr! Blimey!

Project rating: Overall I rate me project a 4 for good success. I would have rated it higher if all me engines had fit and if t' chute had fit in more easily. Begad! I think that paper tubes give more than wood so that the slightly thicher diameter o' t' Econojets won't pass in. This tube was PRECISELY machined without such tolerances.

General pros and cons: T' body tube costs $24 and t' nose cone was $13.50. T' parts are pricy, ya bilge rat, me bucko, but worth it. Well, blow me down! You'll just have t' see it t' know that. Aye aye! In fact, matey, go t' a hardwood store some time and look at woods t' appreciate them. Anyway, me bucko, t' model is light but strong and gives very high flights.

I recommend wood if you'd like t' get attention at a launch. I also learned at this launch that vaseline is nay t' best lubricant for reloadables because it can melt down into t' propellant. It didn't happen t' me, me bucko, but a long-time flyer said that it can, me bucko, especially with hotter motors.
