RT4 / WELD-IT-YOURSELF KIT

Tube Rocket Stove, 4 in

Concept image of the Tube Rocket Stove, 4 in welded and finished, generated from the CAD designConcept image
Concept image made from the CAD design, not a photo. Prototype photos coming soon.

The rocket stove everyone builds from 4 x 4 square tube, with the cutting done for you. We laser cut the riser, burn tunnel and feed from 3/16 in wall tube. The riser's mitered end has box fingers that lock it square on the tunnel, and the tubes drop onto tabs in a flat base, so it stands ready to weld with no chop saw, no measuring and no jig. Cut in Greenville, Texas.

Coming soonEvery kit is prototyped and test-built before it goes on sale.

What you’ll need

  • MIG or flux-core welder (a 120 V machine handles 3/16 in tube in two passes)
  • Angle grinder with a flap disc
  • Two small clamps and a small square
  • Welding helmet, gloves, jacket and safety glasses

Finishing

  • The tubes and parts ship bare with a light oil film. Wipe them down with a degreaser before welding.
  • Grind the welds and every outside edge smooth.
  • Paint the outside with a high-heat paint rated to 1200 F, or leave it bare and oil it. The riser will burn the paint off near the top; that's normal.
  • Burn the first fire outdoors before cooking on it, to cure the paint and burn off any oil.
  • Empty the ash when the stove is cold: lift out the shelf and tip the stove forward.
  • Store it dry with the pot support off.

Safety

  • Outdoors only. A wood fire makes carbon monoxide: never use it in a tent, vehicle, camper, garage or under an awning or closed roof.
  • Set it on bare ground, gravel, stone or concrete, level and clear of dry grass. The tunnel radiates heat downward: never use it on a table, a tailgate, a deck or a cooler.
  • Burn dry sticks and small split wood only. Never use gasoline, lighter fluid or other liquid fuels.
  • Center the pot on all four arms. Don't move the stove while it's lit or while a pot is on it.
  • The whole stove gets hot enough to burn, and the riser glows. Keep kids and pets back, and use gloves.
  • Many campgrounds and public lands ban wood fires and wood stoves during fire restrictions. Check the rules and burn bans before every fire.
  • Keep water or an extinguisher nearby, and let it cool completely before you pack it.
