How Plank Making Works

The Plank Make spell (requires 86 Magic, Dream Mentor quest) converts logs into planks without visiting a sawmill. Buy logs cheap from GE, cast spell to make planks, sell planks back to GE for profit. Each cast costs 2 Astral runes, 15 Earth runes, and the sawmill fee (varies by log type).

The Process:

  1. 1. Buy logs from Grand Exchange (oak, teak, or mahogany)
  2. 2. Bring logs + runes to bank (Lunar Isle bank recommended)
  3. 3. Cast Plank Make on logs (converts 1 log per cast, can do 27 at a time)
  4. 4. Inventory fills with planks, bank them
  5. 5. Repeat until all logs converted
  6. 6. Sell planks on Grand Exchange for profit
Requirements

Mandatory:

  • 86 Magic (to cast Plank Make spell)
  • Dream Mentor quest (unlocks Lunar spellbook)
  • Lunar Diplomacy (prerequisite for Dream Mentor)
  • 500k-2M GP starting capital (to buy initial logs + runes)

Recommended:

  • Rune Pouch (holds Astral + Earth runes, saves inventory space)
  • Lunar Isle teleport (bank is right next to you for efficiency)
  • Steam staff or Tome of Fire (provides infinite fire runes if needed)

Step-by-Step: Plank Make Spell Method

Optimal Setup at Lunar Isle Bank
1

Check GE prices for best plank type

Use GE Tracker to see which planks have best profit margin (oak usually best).

2

Buy supplies from Grand Exchange

Buy 5,000-10,000 logs (oak/teak/mahogany), plus Astral runes (2 per plank) and Earth runes (15 per plank). Use Rune Pouch!

3

Teleport to Lunar Isle

Lunar Isle teleport spell or Home teleport if you moved your house there. Bank is right next to spawn.

4

Withdraw 27 logs + ensure rune pouch equipped

Fill inventory with logs. Rune pouch should have Astral + Earth runes (and optionally Fire if using spell icons).

5

Cast Plank Make on each log

Click Plank Make spell → click log. Each log converts to plank (takes 3 ticks). Do all 27 logs.

6

Bank planks and repeat

Bank all planks, withdraw 27 more logs. Repeat until all logs converted (takes 1-2 hours for 10k logs).

7

Sell planks on Grand Exchange

List planks slightly below market price for instant sell, collect profit.

Detailed Profit Breakdown (Oak Planks)

Per-Plank Costs & Revenue:

  • • Oak log cost: 25 GP
  • • Sawmill fee (via spell): 250 GP
  • • Astral rune cost (2 runes): ~20 GP
  • • Earth rune cost (15 runes): ~5 GP
  • Total cost per plank: 300 GP
  • • Oak plank sell price: ~450 GP
  • Net profit per plank: 150 GP

Hourly Profit Estimate:

  • Planks per hour: 800 planks (semi-AFK pace)
  • Profit per hour: 800 × 150 GP = 120,000 GP/hr
  • Magic XP per hour: 800 × 70 = 56,000 XP/hr

Mahogany planks (higher profit): 600 planks/hr × 300 GP profit = 180k GP/hr + higher Magic XP

Pro Tips for Maximum Efficiency

Use Rune Pouch: Stores Astral + Earth runes, freeing inventory space for 2 extra logs per trip. Huge efficiency boost.

Lunar Isle bank is optimal: Bank is right next to spawn. Castle Wars bank also works but slightly further from teleport spot.

Check margins before buying bulk: Plank prices fluctuate. Test with 100 logs first, see if you profit, then buy 10k+ logs if margins good.

Oak planks usually best profit: Mahogany has higher GP per plank but slower (fewer planks/hr). Oak is sweet spot for GP/hr.

Combine with Magic training: You're gaining 50-60k Magic XP/hr while making money. Better than bursting if you need GP.

World hop if bank crowded: Lunar Isle can be busy during peak hours. Hop to less populated world for faster banking.

Semi-AFK friendly: Click spell → click log → repeat. Can watch Netflix between inventories. Good low-attention money maker.

Alternative: Plank running for others: Join "Plank Running" CC and run logs to POH for 70k+ GP per run (5-10 mins). Higher profit but requires trust.

Why Plank Making is Profitable in 2026

Construction is one of the most expensive skills in OSRS, and players training it need millions of planks. Most players buy planks directly from the GE rather than making them manually because it saves time. This creates opportunity for you to be the supplier and profit from the convenience markup.

The Plank Make Spell Advantage

Before the Plank Make spell (added in 2006), players had to physically visit the Sawmill operator northeast of Varrock with logs and coins. This was tedious and slow. The Plank Make spell lets you convert logs to planks from anywhere — bank, POH, even GE. This convenience comes at a cost (runes), but the time saved makes it profitable.

At 86 Magic with Dream Mentor completed, you can cast Plank Make which costs 2 Astral runes + 15 Earth runes per plank. The spell also deducts the sawmill fee (250 GP for oak, 500 GP for teak, 1,500 GP for mahogany). Total cost is much lower than buying finished planks from GE, creating your profit margin.

Which Plank Type Makes Most Money?

Oak planks typically have the best GP/hr because you can make 800-900 per hour. Profit is ~150 GP per plank, so 800 × 150 = 120k+ GP/hr. Mahogany planks have higher profit per plank (~300 GP) but you make fewer per hour (600-700) due to higher cost and slower pace, netting similar total GP/hr.

Teak planks are middle ground but generally worst profit because cost and sell price are both mid-tier. Always check current GE prices at GE Tracker before committing to large batches.

Alternative: Butler Method

If you have 50+ Construction, you can use the Demon Butler in your POH to make planks. This is faster than Sawmill but slower than Plank Make spell. Butler charges 10k per 26 planks unnoted, which cuts into profit. Only worth it if you don't have 86 Magic yet.

When NOT to Make Planks

If log prices spike or plank prices crash, margins disappear. For example, if oak logs jump to 40 GP and oak planks drop to 420 GP, your profit per plank falls from 150 GP to 80 GP — not worth the time. Check prices daily and only make planks when margins are healthy (100+ GP per plank minimum).
