Drop Forged Bracelet - make jewellery from tools

Picture of Drop Forged Bracelet - make jewellery from tools

I was browsing a cheap tool stall in a market, and came across a set of "drop forged" spanners for the price of a cup of coffee.

As I am sure you know, you get what you pay for when it comes to tools. I put them back on the rack, saying to myself; "That cheap, they'll bend around my hand before they shift a bolt!"

I paused, struck by the Maker Muse, and bought the spanners.

Step 2: Bend

I started by clamping the spanner in the vice, fitting the adjustable spanner to the end, and then leaning.

There's no need to be brutal, and no point in moving quickly - moving steadily gives you a lot more control over the point and extent of the bend.

Feed the spanner through the vice a few millimetres at a time, and bend a bit more each time.

Step 3: Squeeze

I accidentally ended up with more of a circle than I wanted, but I found that putting the curved spanner in the vice, then closing it slowly, gave me some of the oval shape I was aiming for.

As you bend and squeeze, stop occasionally and try it on - it is surprisingly easy to close the gap at the end too tightly to fit over your wrist. The spanner is not so springy as normal jewellery, so not so easy to force into place if it's closed too tight.

Obviously, I'm entering this in contests - if you can see a "vote" banner at the top of the page, I would be grateful for a few clicks.

Nice! I've got a pile of old wrenches that have been waiting to be used for something like this. Thanks for the great idea!

If they're fairly old wrenches and maybe made in the US, they will be too strong to bend like that. This has to be done with super low quality tools made from a very soft forged steel. Unless you use an acetylene torch to heat it red hot first. The Chinese stuff is what you want.

I was wondering if annealing wouldn't help.

You're welcome - post pictures when you finish.

Thanks!

They could even serve in place of brass knuckles? ~:- }

No, not really.

Have you tried using a MAPP gas or propane torch to heat the spanner (wrench in US) and bend it around a form? You might get more consistent curves, but it would take more time to create the form.

Kiteman (author)  Silvester105281 month ago

I guess I would make a form or jig if I was going to make a lot of these, but for just the odd one or two, brute force and ignorance is fine.

as a silver smith, you can get a steel bracelet mandrel...perhaps the working end of a hickory baseball bat may work(silver, being softer, i have used a bat before).

I am not sure what a spanner is but what I see in the photo is an open/box end wrench and an adjustable wrench...

It's like the hood of a car is a "bonnet" and the trunk is a "boot" :)

I only wish at the end of the article it said.. and Bob's your uncle...( Im not a Brit.. but I try not to limit my education to just our shores ;-) )

Fun fact; my uncle is, in fact, called Robert!

"Spanner" is the English word for what Americans call a "wrench".

In English, "wrench" means a sudden, violent, twisting pull.

Colonials - what can you do with them?! :)

Drop forging means a heavy hammer smashes hot metal into the shape you want. Not molten, but hot. If never hardened, I guess you get these Chinese tools. Is 'jewellery' the English spelling? Just 'jewelry' in USA.

Kiteman (author)  danzo3211 month ago

I know what drop-forged is (I'm from a steel town), I'm just not convinced that happened to these spanners.

And, yes, "jewellery" is the correct spelling...

I've got some old wrenches here at my place I might just have to try this.

Cool, post a picture when you do.

got my vote, I was just given a bucked full of random wrenches and this is now on my to do list.

Kiteman (author)  Triclaw1 month ago

Thanks!

Kiteman (author)  Triclaw1 month ago

Excellent!

This is cool. Anyone doing this keep in mind that if the wrenches you use are plated the plating may break, crack chip and peel in the bending. Nothing that you can't deal with but still might happen. As for the comment about weight, you can get small size wrenches in longer handle lengths that could actually make some thin light almost delicate looking bracelets. I see a lot of other adaptations that this could inspire. Good luck to all.

LOL!

bit heavy for jewely ?
Kiteman (author)  Phoghat1 month ago

It's a cheap spanner, not exactly high-grade tungsten, so it's no heavier than then bracelets my wife wears.

Now I just need an instructable for something to do with a set of fake drills that bend if you try to drill through something tough like softwood or MDF.

Moral: Don't expect decent tools from poundland.

Kiteman (author)  yellowcatt1 month ago

Bend them into loops, make a chain?
