Lone Star Swing-Arm Grill for FP30

Concept image of the Lone Star Swing-Arm Grill for FP30 welded and finished, generated from the CAD designConcept image
Concept image made from the CAD design, not a photo. Prototype photos coming soon.

Cook over the fire, then swing the grate off it to add wood or rest the food. A 16 in square grate rides on a steel arm that turns on a post at your FP30's corner. Drop the steel key into another pair of slots to raise or lower it: six heights, from 2-1/2 to 12-1/2 in above the rim. The pit holds the post at the ground and at the rim, so there's nothing to clamp, bolt or drive into the ground, and it works on a patio. Laser cut from 10 ga steel and 1-1/2 in square tube 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 10 ga)
  • Angle grinder with a flap disc and a wire wheel
  • A square, two clamps and a rubber mallet
  • Chipping hammer for flux-core slag
  • Welding helmet, gloves, jacket and safety glasses

Finishing

  • The parts ship bare with a light oil film. It's a rust preventive, not a cooking oil: degrease every part before welding and again before seasoning.
  • Never paint the grate. The post, foot plate and saddle can take high-heat paint; keep paint off the hub collars and key, where steel turns on steel.
  • Chip off all flux-core slag and wire-wheel the welds and bar tops to bright steel.
  • Season the grate like cast iron: a thin coat of high-smoke-point oil, then 30 to 45 minutes over a hot fire. Repeat two or three times.
  • A drop of high-temperature anti-seize on the post where the collars turn keeps the swing smooth.

Safety

  • Made to fit the FP30. The corner leg must sit in the foot plate's slot, and the saddle must straddle the rim corner, before you hang the arm.
  • Holds 20 lb of food and cookware on the grate, such as a 12 in cast iron skillet with food in it. It is not a seat, step or shelf; don't lean on the arm.
  • The grate, arm and hub get as hot as the fire. Swing it by the tail handle with grill gloves, and change heights only when the grate is empty.
  • Swing the grate out of the fire before you add wood, and keep kids clear of the arm's path.
  • Outdoors only. Every safety rule for the fire pit applies.
