A bottle tree looks complicated because of the spikes. It isn't. The frame is a mast, eight legs and eighteen flat-bar rings, and none of it needs a ring roller: each ring is bent as an octagon at the legs, which is why a grinder and a welder are enough.
What does need care is the shopping list. Order too little flat bar and you stop halfway; order the wrong pipe and the legs won't sit on the base star. The numbers below come straight from the plan's material calculator.
The steel to order
Everything is nested onto standard 20 ft bars. For the 10 ft tree that comes to 28 bars, about 453 lb of steel, with roughly 7% waste.
| Section | Used for | Bars (20 ft) | Weight |
|---|---|---|---|
| Flat bar 1-1/4 × 1/8 in | 18 rings | 11 | 117 lb |
| Rebar #3 (3/8 in) | 614 bottle spikes, 3-1/4 in each | 9 | 68 lb |
| Pipe 1/2 in Sch 40 | 8 legs + 8 mid-height braces | 5 | 85 lb |
| Rect. tube 2 × 1-1/2 × 1/8 in | 8-arm base star | 2 | 111 lb |
| Pipe 2 in Sch 40 | Centre mast, 122 in | 1 | 73 lb |
| Total | 28 | 453 lb |
Ring 1 doesn't fit on one bar. The bottom ring is longer than 20 ft, so it is made from two pieces butt-welded with a V groove. Every other ring comes from a single length. The cut list shows which rings share a bar.
The finished tree weighs about 350 lb. That is light enough to stand without guy wires on the base star, and heavy enough that you want two people to lift it.

This is the full list used on the build. Nothing on it is specialist.
- MIG welder, or a stick welder with 2.5 mm (3/32 in) rodThe steel is all 1/8 in or thinner, so a hobby-size machine is plenty. A MIG is faster on 614 spikes.
- 4-1/2 in (115–125 mm) angle grinderFor cutting every piece and cleaning the welds. A second grinder saves swapping discs all day.
- Cut-off discs and flap discsYou will go through more cut-off discs than you expect: there are 614 spikes to cut.
- Magnetic welding squaresThey hold legs and braces at the right angle while you tack. Worth more than a third pair of hands.
- 4–6 clamps and an engineer's squareFor holding rings to the legs before the first tack.
- Tape measure, spirit level, plumb lineThe mast has to be plumb before the legs go on, or the cone leans.
- Auto-darkening helmet, welding gloves, safety glassesNon-negotiable. You will strike several thousand arcs on this build.
- Drill and a 12 mm (1/2 in) bitOnly if you anchor the base to the ground.
What you can skip
- A ring roller. The rings are bent at the eight legs and finish as octagons. An octagon uses 2.6% less bar than a circle; that surplus is your working tolerance.
- A plasma cutter or CNC table. Every cut is straight, and a grinder handles all of them.
- A big welder. Thin flat bar and 3/8 in rebar don't need high amperage. Penetration matters more on the base star than anywhere else.
Paint, lights and bottles
- Degreaser and metal primerBare steel outdoors starts rusting in days. Degrease before priming or the paint lifts.
- Outdoor metal paint, 2–3 coatsThe tree has about 104 sq ft of surface. Brushing every face of every spike is the slowest job on the build.
- Outdoor-rated warm LED string lightsThey run along the rings, behind the glass, so coloured bottles glow from inside the cone.
You don't need 614 bottles. Each spike takes the neck of a standard 750 ml bottle, hanging neck-down. Fill every second spike and you need 307; every third, 205. Start on the bottom rings, where bottles show best, and work up as the collection grows.
Lights and wiring are outside the scope of the plans. Use outdoor-rated equipment and install it to your local electrical standards.
Where the 53 hours go
The time model comes from the hours actually logged on the published tree.
| Stage | Time |
|---|---|
| Frame: base star, mast, 8 legs | 8–10 h |
| Bending and welding 18 rings | 8–10 h |
| Welding 614 spikes | 12–15 h |
| Grinding and degreasing | 4–5 h |
| Painting, 2–3 coats | 16 h |
Painting takes longer than welding. If you can, spray the frame before the spikes go on, then touch up.
