How To Make Steel Knuckles

Disclaimer : These are not a toy, and this isn't a mockup made of out of harmless materials, These are dangerous and nasty and I would hope after the fabrication of these you behave rationally. Steel is dense, bone is brittle. That being said lets begin. Im aware that one method of cutting,drilling or finishing metal might not be available too you so i attempt too offer alternative methods for fabrication. Please excuse the poor images im no photographer.

Bill Of Materials :
1. 1ft long by 4in wide by 1/4in thick plate steel.
2. 1in diamter bi-metal hole saw
3. A way to weld, or you could use 1/2in thick (much harder too cut ) or simply leave them 1/4in thick.
4.A way too cut metal ex. metal cutting jigsaw,sawsall or hacksaw(for those of you with real gumption :) personally i'll be using a bandsaw with a 24 TPI blade.
5. Metal center punch and hammer for marking center points in the plate steel.
6. 3/4inch drum sander with 80 grit sandpaper
7. scribe,sharpie or pencil(hardest too see,wouldn't advise it ) if a scribe is used get one where the tip i made out of tungsten so it wont round over on the mild steel.
8.A ruler that can measure in millimeters if you dont want too purchase one you can download one at www.boltdepot.com
9.Square or straight edge
10. posterboard, cardboard or computer paper for the template

Step 1 Steel Preparation

When you purchase steel from your local hardware its coated in zinc oxide too protect it from corrosion that might occur on the shelf. Use your 80 grit sander too remove this coating until you are left with bare steel. If you are gonna draw the silouhette of the knuckles on with a sharpie i would wipe it down first with rubbing alcohol or minerals spirits.

nice job...i make knives and have always wanted the knuckle duster version trench knife...off to the shop i go. like my brass gears one can drill a series of small holes and punch em out, for those with limited tools.

[curt-fullmer]

You're absolutely right

[black hole]

Where did you get that steel? I'm always looking for metal to make knives.

[curt-fullmer]

this is just 1/4" plate from lowes.

[shadow wave rider]

awsome. totally awesome. this is like the only ible when someone actuallly makes real ones. which type of drill piece did you use. did you use the paddle type or the cylender type.

[curt-fullmer]

Dont use the paddle bits(spade bits) they're not tempered to cut steel. Also the cylinder bits come in two different types. Use the white cylinder bits only(bi- metal hole saw) the black ones are for wood and the teeth will shred off with mild steel.

ok cool. ive got small fingers so a large normal drill piece should do. i don't want them banging against my fingers because they will hurt. also i've slightly alered this. your know how you used two layers, i cut a space in between to slide in a little spike. not sharped becuase you dont want blood everywhere but it will hurt.... alot. mwhahahahahaha. so you better be nice to me.lol. mwhahahahahahahahahahahahahahahahahahahhahahahahahaahahaha(cough, cough.)

[curt-fullmer]

Thats so awesome. Super excited to see what you come up with.

[masterochicken]

I honestly think the plug welds give it a cool detail. Good job.

[srohwer]

I could see fabricating the template out of corrugated cardboard. Lots of chances to experiment, design, etc. before the fabrication.

Do you think a product like JB Weld would be sufficient to hold them together?

Very nice 'ible. Thanks!

[curt-fullmer]

Cardboard or posterboard for metal fab is very helpful, if you ever watch any auto shows they always use cardboard first ex.floors,hood scoops etc.

[codongolev]

if you wanted, you could bolt or rivet them together.

[Scott_Tx]

yeah, I was thinking rivets too. It'd look cleaner I think

[curt-fullmer]

You know i didnt even think about that you could bolt or rivet them together. Good thinking. You could try JB Weld maybe in time they would come apart but is suppose you could just JB weld them again.
