Propane forges give makers a fast, controllable heat source for shaping steel, melting scrap, and running small foundry projects without a coal pile or electric hookup. The right one depends on what you plan to do: bend small stock, draw out knife blanks, or pour molten metal into ingots. Capacity, burner layout, and insulation thickness all change the day-to-day experience, and the gap between a hobby unit and a workshop workhorse is bigger than it looks. This shortlist focuses on portable single-burner forges, dual-burner setups, and a few melting furnaces that handle gold, silver, copper, and aluminum with reliable heat retention.

The Details Behind The Selections
The Simond Store single-burner forge is the kind of unit that lowers the entry barrier to knife making. It weighs little and slips onto a workbench, which makes it approachable for someone setting up a first shop in a garage or basement. The internal chamber measures roughly 2.75 by 4 by 10 inches, so a short blade blank or a small decorative hook fits without crowding.
Single-burner design is honest about what the unit does best: short, focused heat sessions for stock under a foot long. Compared with the dual-burner Nelyrho kit later in the list, this one trades heat spread for portability, which is the right call for hobbyists who only need to forge one piece at a time.
The Value In It
- Light enough to carry between work areas, useful for a shared shop or tight garage
- Tight 2.75 by 4 by 10 inch chamber suits short blade blanks and small hardware
- Insulated body keeps heat contained, so a beginner stays safer while learning torch control
- Connects to a standard propane tank, no specialty fittings required
Points To Note
- Single burner means uneven heat across wider stock; pieces may need constant rotation
- Owners commonly report that long workpieces hang past the chamber edge, which costs heat efficiency
- Less thermal mass than the Nelyrho kits, so it cools faster between sessions

Right Fit For
First-time knife makers and hobbyists who only need to heat short stock on a crowded workbench.
Where Another Pick Suits Better
Shoppers who plan to work on longer bars or wider stock should consider the Nelyrho 2 Burner Propane Blacksmith Forge Kit for more even heat coverage.
The Nelyrho 1 Burner kit is built for someone who wants to unbox a forge and start shaping metal that afternoon. The propane hose connection is sized for the standard tanks sold at most hardware stores, which removes one of the early friction points beginners run into. It carries the same single-burner logic as the Simond Store unit, but the framing leans more toward an at-home maker than a traveling demonstrator.
For a small workshop setup, the kit hits a practical middle ground. It is more contained than the dual-burner option but feels sturdier than many budget single-burner boxes, and the layout supports a tidy first forge station with room left for an anvil and quenching bucket.
Where It Delivers
- Standard tank compatibility means fewer trips to find a refill
- Sturdy framing relative to most single-burner kits in this size class
- Beginner-friendly setup that needs minimal extra gear to start forging
Things To Consider
- Single burner shares the same heat-spread limits as the Simond Store unit
- Lacks a melting crucible, so it is a forging tool rather than a casting tool
- Documentation and included accessories vary, so some buyers end up sourcing tongs and a regulator separately
Whose Shelf It Belongs On
Home hobbyists and weekend makers who want a ready-to-go forging station without sourcing every part individually.
Look Elsewhere When
Shoppers who need to melt and pour metal should skip this kit and look at the Nelyrho 6KG Propane Melting Furnace Kit instead.
The 2-burner kit is where Nelyrho starts to feel like a workshop tool rather than a hobby accessory. The second burner spreads heat across a wider chamber, which matters the moment you start working on longer bars or thicker stock. Where the Simond Store and the Nelyrho 1 Burner require constant rotation to chase the heat, this setup gets closer to even temperature across the workpiece.
Build quality is the headline change. The stainless steel body and 1 inch insulation layer hold heat longer between cycles, which means fewer trips to relight and faster recovery after opening the forge to reposition a piece. For a mid-size project like a full-tang knife or a small axe head, the time savings add up fast.
Notable Gains
- Two burners deliver more uniform heat across wider workpieces
- Stainless steel body supports a 0 to 30 PSI burner nozzle range, giving precise flame control
- 1 inch thick insulation reduces fuel use per session and keeps the outside cooler
- Capable of reaching 2600°F, enough for most blade and tool steel work
- Better long-run value for a maker moving beyond starter projects
Honest Caveats
- Heavier and bulkier than either single-burner option, so it lives on a bench rather than moving around
- Higher propane draw means bigger tanks or more frequent refills during long sessions
Built With In Mind
Makers stepping up from their first forge to mid-size projects like full-tang knives, hatchets, and larger hardware.
Reach For A Different Pick When
Anyone focused on melting and casting metals should reach for the Nelyrho 7KG Propane Melting Furnace Kit rather than this forging setup.
The 6KG melting kit is the first step into foundry work on this list. The package arrives with the core cast of accessories: a 6 kilogram graphite crucible with a built-in pouring spout, an ingot mold, dual crucible tongs, fire brick, and gloves. That matters because the worst part of starting a small casting setup is sourcing every piece separately, and this kit removes the worst of that friction.
The 30 PSI regulator and 135,000 BTU burner pair up for fast heat-up, which keeps melt cycles short and fuel use contained. The graphite crucible handles aluminum, copper, and precious metals with ease, and the included fire brick gives a safe base for the first pours.
Positive Points
- Complete accessory bundle, so a first-time caster avoids the scavenger hunt for tongs and molds
- Pouring spout on the crucible reduces spills during transfer to the ingot mold
- Stainless steel furnace body holds up to repeated high-heat cycles
Things To Weigh
- Graphite crucibles are consumables and need replacement after heavy use, adding to long-term cost
- 6KG capacity is fine for hobby pours, but limits the size of any single cast piece
At A Glance
Who It Suits Best
Backyard casters and jewelry makers running small batches of aluminum, copper, silver, or gold.
Skip It When
Anyone running larger foundry runs or recycling bulk scrap metal should consider the Nelyrho 12KG Hinged Flip Top Propane Melting Furnace instead.
The 7KG kit adds a feature the 6KG version skips: a proper insulated support stand. That single addition changes the day-to-day feel of using the furnace, because the stand protects the workbench from radiant heat and gives the whole setup a stable, repeatable position. For a small workshop that sees regular pours, that stability matters more than it first sounds.
The 7KG capacity is a small jump over the 6KG kit, but it adds headroom for slightly larger ingots and longer continuous melts. The stainless steel body, combined with the support stand, makes this the most workshop-ready furnace in the mid-tier of the list.
Notable Upsides
- Insulated support stand protects floors and benches from heat damage during long melts
- 7KG capacity offers a small step up from the 6KG kit for larger ingots
- Stainless steel body delivers the durability expected for repeated foundry sessions
- Suited for aluminum, copper, gold, and silver, covering the most common hobby cast metals
Trade-Offs To Consider
- Still uses a consumable graphite crucible, so ongoing replacement cost applies
- Taller furnace body needs more vertical clearance than the 6KG setup
Who Should Grab It
Workshop users recycling scrap metal and small foundries needing a stable, repeatable melt station.
A Better Fit Elsewhere
Shoppers planning to scale into larger batches will find the Nelyrho 12KG Hinged Flip Top Propane Melting Furnace offers more room to grow.
The 12KG furnace is the largest unit on the list and the most directly aimed at small batch production. The hinged flip top changes the experience in a way that is easy to underestimate until you have used a lift-off lid. Adding charge material, checking melt progress, and skimming impurities all become faster, which matters when a session runs for hours.
Reaching 2500°F opens the door to gold, silver, copper, and aluminum in generous batches. The 1 inch insulation layer is consistent with the rest of the Nelyrho line and keeps heat inside the chamber where it does the work, while the stainless steel shell takes the punishment of repeated thermal cycling.
Noteworthy Benefits
- 12KG capacity supports larger single pours and longer continuous melting
- Hinged flip top speeds up charging, skimming, and visual checks
- 2500°F ceiling covers all common jewelry and scrap metals
- Stainless steel body with 1 inch insulation balances heat retention with structural life
Possible Compromises
- Bigger footprint demands a dedicated corner of the shop rather than a tabletop perch
- Higher fuel draw per session, so propane budget matters for frequent users

Consider Something Else When
Beginners who only melt occasionally will find the Nelyrho 6KG Propane Melting Furnace Kit a friendlier first step.
What To Weigh Before Choosing A Propane Forge
The first question is what you actually plan to do at the anvil or the casting table. A single-burner forge handles short knife blanks, hooks, and small hardware without complaint. A dual-burner setup spreads heat more evenly across longer or wider stock, which is the difference between fighting hot spots and just working the steel. A melting furnace is a different tool entirely, built around a crucible rather than an open chamber, and choosing one means committing to casting workflows.
Burner count and insulation thickness drive fuel use as much as heat output. A 1 inch insulation layer keeps heat inside the chamber and reduces the runtime of the burner, which adds up over a year of weekend sessions. A body made from stainless steel resists heat fatigue far better than thin painted steel, and the difference shows up in the third or fourth year of ownership rather than the first.
Capacity scales directly with the size of what you want to make. A 6KG crucible covers hobby ingots and small jewelry pours. A 12KG crucible handles small production runs and bulk recycling without the constant top-up of the smaller furnaces. Match the chamber or crucible size to the largest piece you expect to heat in one pass, then work backward from there.
Finally, think about the space the forge will live in. Portable single-burner units fit on a fold-out bench, while a 12KG furnace wants a permanent corner with a noncombustible surface. Propane tank access, ventilation, and distance from combustibles all shape whether a given unit fits your shop or your schedule.
Key Considerations Across These Picks
Where Shoppers Go Wrong
One common slip is buying a forge sized for a project that never happens. Makers often imagine long sword-length bars when a 4 inch chamber would cover ninety percent of real use, then end up with a unit that costs more and heats less efficiently. Match the chamber to actual workpiece dimensions, not aspirational ones. A second trap is underestimating propane logistics: a high-BTU furnace drinks fuel fast, and skipping the propane tank and regulator budget leads to a half-finished first session.
What The Higher Tier Buys
Stepping up to a dual-burner forge or a 12KG furnace is mostly a purchase of consistency, not just capacity. Premium models hold heat longer between cycles, spread temperature more evenly across the workpiece, and arrive with accessories that cheaper kits treat as optional. For a maker who forges or casts weekly, that consistency translates into fewer failed heats, less wasted stock, and a shop that runs predictably. For a casual hobbyist, the same premium features are nice but rarely essential.
