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

This is a single staged, me bucko, 3 finned all wood rocket made from parts made by Retro Rocket Works, through Apogee Components. Avast, me proud beauty! Blimey! Its grain is visible and is used t' accent t' looks o' the rocket. So, me hearties, 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). Arrr! Ya scallywag! Blimey! It's solid cherry or mahogany. Blimey! Blimey! As an inexperienced woodworker, me bucko, me hearties, me hearties, I really do nay know all o' me woods. But I can say that this nose cone is pretty. Avast, me proud beauty! Avast! Blimey! It's medium dark hardwood, smooth, and precisely machined. Arrr! Blimey! It came with t' beginnin' o' a pilot hole in t' base for me t' drill in me shock cord screweye. Arrr!

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

T' body tube is a similar color wood t' t' nose, arrr, with beautiful striping of grain. Ya scallywag! It's 48 inches long, me hearties, shiver me timbers, matey, t' standard length o' tubin' sold by t' Retro Rocket Works company. Begad! Ahoy! It appears t' have been made in layers. Ya scallywag! It appears t' be wood throughout. Blimey!

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

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

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

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

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

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

T' rocket flew straight and stable, and recovered about right. Blimey! Blimey! As I said, a 10 second delay would have been better yet. Begad! 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, matey, 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, t' G33-7, shiver me timbers, me hearties, namely. Ya scallywag! Blimey! Results were similarly picturesque. Well, blow me down! Begad! Blimey!

My simulator predicts even better results with an H97, arrr, but because t' fins do nay go through t' body tube, me bucko, I don't feel comfortable with that. I'm gutsy, but do nay want any shreds.

Project rating: Overall I rate me project a 4 for good success. Ya scallywag! Avast! I would have rated it higher if all me engines had fit and if t' chute had fit in more easily. 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. Aye aye! Ya scallywag! T' parts are pricy, arrr, ya bilge rat, but worth it. You'll just have t' see it t' know that. Ya scallywag! Arrr! In fact, go t' a hardwood store some time and look at woods t' appreciate them. Anyway, t' model is light but strong and gives very high flights. Blimey!

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. Ahoy! Ya scallywag! It didn't happen t' me, me bucko, but a long-time flyer said that it can, ya bilge rat, especially with hotter motors.
