AFK Smithing/Crafting/Magic method (alternative use for gold ores/bars)

Tldr; Rather than making gold bracelets with gold bars, make gold amulets from gold ore/bars and lunar string them for ez afk exp.

Requires:
40 Smithing + Goldsmith gauntlets
Recommended:
Varrock armour 2 (method 2 & 3)
80/82 Magic and Lunars (method 1 & 2)
Mud staff (method 1 & 2)

There's a few ways you can do this, but keep in mind, it'd be more efficient in terms of played-time if you smelt the ores at blast furnace, so it just depends how much you value afking/avoiding blast furnace. However you can do this with your excess gold bars, rather than on bracelets.

Method 1 - Using excess gold bars (more efficient, less afk, ~2 minutes afk/invent):
With a mud staff equipped (or whatever you have), and an amulet mould, runes for string amulet and magic imbue in invent. At a furnace, casting imbue inbetween actions, smelt bars into unstrung amulets, and lunar string while running back to bank. Both actions are just over 1 minute afks.
I was getting ~110k exp per hour, split into ~30k/h crafting and ~80k/h magic. Each bar gives 34 crafting exp and ~93 magic exp if imbuing.
Before alching/selling (210gp alch price), each amulet costs ~160gp on the astrals.

Method 2 - Smelting from gold ore (less efficient, more afk ~3 minute of afk/invent):
With a mud staff and Varrock Armour 2+ equipped, and an amulet mould, runes for string amulet and magic imbue in invent. At Edgeville furnace (because Varrock armour), casting imbue inbetween actions, smelt gold ore into bars, bars into unstrung amulets, and lunar string while running back to bank. All three actions are just over 1 minute afks.
Doing this I was getting ~95k exp per hour, broken into ~29k/h smithing, ~18k/h crafting and ~48k/h magic. Individually, each ore->amulet nets 56.2 smithing exp, 34 crafting exp and 96 magic exp (186.2 total exp).
If gold ore is bought from blast furnace, each amulet costs ~385gp before alching/selling to a store (210gp alch price).

"Method" (suggestion) 3 - (potentially expensive for lower levels, not as afk, but no magic level/lunar requirement):
Method is like either of above, just without stringing/imbuing. Essentially, I'd recommend doing amulets over bracelets if you don't currently have the magic level req, and just holding onto the unstrung amulets for when you do, since stringing is an afk ~130k/h magic exp. Just keep in mind this is relatively expensive if you are buying ores (6k gp/invent), since you won't be able to sell them until you have the magic/lunar req. When you do, each amulet would cost ~365gp before alching/selling to a store (210gp alch price).

N e ways, lemme know if you have any suggestions etc. c u
