The DIY Dagger…

Friday, October 9th, 2009

Alright, so this dagger is decidedly *not* a DIY job, but it very well could be:

Pipe Knife Dagger

Pipe Knife Dagger

Technically, this is not a knife, but purely a dagger, as the design is one that is best suited for thrusting, and not much else. However if you had the right tools, this kind of weapon would be dirt cheap to make. You start if with a few basic ingredients, a section of steel pipe, a couple of nuts and bolts, a replacement rubber walking stick foot, a hacksaw, a drill, and a sharpening stone or grinder, mix them all together thoroughly, throw in  a healthy quantity of  elbow grease, and voila! you have a pipe dagger.

OK… that didn’t sound as simple as I thought it would. So don’t go trying this at home. But you get the idea. Actually when I first laid eyes on it I thought it was some sort of cheap, mass produced bayonet. Hey, don’t laugh…  Wouldn’t be the first time some poor infantry unit got cheap equipment… :/

The next best thing to Adamantium implants…

Saturday, May 9th, 2009

A couple of days ago I got a post from a reader (Thanks SniperFodder!) with a link to a page on Geekologie that showed videos of a very, very interesting set of home made wolverine claws. Here is the first of the two, very intriguing videos in question, mostly of the maker wreaking wanton destruction on some nefarious box of doom for some seriously heinous crimes we are clearly all blissfully unaware of:

Yes, all kinds of cool and everything, if you are into that kind of thing… Oh, who am I kidding, I love this stuff… I probably would try a more blade worthy opponent than an old box, but that’s just me… 🙂

What really caught my attention, however, was the construction vid that accompanied the shameless *cough* display of aggression above…:

Now as a person who has spent countless man-hours thinking about this kind of thing, let me just say that what this guy did was actually very impressive. Not that there haven’t been countless wolverine claw replicas and home made diy Wolverine claw jobs, but this particular construction dealt very directly and extremely competently with two aspects of arm mounted blade design that I have always found to be weak links in your traditional back yard / junk yard wolverine claw project.

The first and most common point of failure I see is in the blade attachment and rail mechanism. I see a lot of people use sliding drawer rails for the rails of their wolverine claws, and while it works, (works very well in fact), and is good for show, frankly, so far as strength is concerned, the vast majority of them wouldn’t hold up to the repeated stresses of cutting a slice of gouda cheese. Nope. Not even some “finely aged”, moldy gouda, half ready to decompose into a pile of technicolor goo.

Now this dude addressed this weakness by fabricating a simple sliding plate/tongue-in-groove rail. It is a design I’ve always thought would fit the ticket perfectly, but never had the time to try. And here, you can see it in action. Now I am, by no means, saying it’s a perfect solution. It has it’s weaknesses as well. In fact, you may or may not be able to tell from watching the vids, but that plate generates a lot of friction, so while it is really strong, it is also tougher to deploy smoothly. It also looked like he used a single rail tongue for all three blades. Not really how I would have done it, but it seems to work.

But the part that I found really impressive is his bracing. Yes, it is made of bent and brazed copper tubing, which I saw lots of commenters deriding him about, however what they fail to realize is that, assuming his brazings are strong,  his design eliminates one of the biggest weak points of any wolverine claw system. The arm attachment mechanism.

I see all kinds of wolverine claws or just home made arn claws/blades/ziphoids in general, with two little straps, maybe a soft leather arm band or something. The smarter ones go for a solid plate and attach that to their arms, though, again, with more little straps. The thing is, those little itty bitty strips of fancy arm floss just won’t hold up to strong impacts. They suffer from one simple flaw: They are too flexible.

No matter how strong the system itself is, straps and soft leather allow seem to allow the whole rig,to move backwards and forwards on your arm. I’ve seen this happen even with full forearm vambraces if the leather used to make them isn’t hard enough. In contrast, this guy used a solid framework of copper tubing that will not give, and is so closely fit to the dimensions of his forearm, that he should have enough stability and control with it that he could make bacon with those blades, should he deem it necessary.

What more can I say. The whole get up may look ugly, but mechanically, it’s really a thing of beauty. Incidentally, while the page I found these videos on say they are “fully functional” I think that depends on your point of view. Our friendly niegborhood Wolvie sports a set of double action, fully automatic blades. This guy, on the other hand (or, in this case, the other claw arm) made single action blades, (manual retract, automatic deploy) as far as I can tell. So it’s certainly close to the kinds of functionality Wolverine gets from his claws, but no cigar.

And just in case there is any question about what I mean by my earlier comment regarding the bacon, let me just be clear. Bacon is *always* necessary. But you don’t always have the opportunity to make bacon using a set of wolverine claws strapped to your forearms… That is just too cool for Ginsu school.. I’m just sayin. 😀

How To Make Retractable Wolverine Claws

Nate used Photoshop to enlarge an image of Wolverine’s claws from the X-Men movie that he had downloaded. This allowed him to print out the image until it fit exactly onto the 1″ x 1/8″ Aluminum Flat Bar that he had purchased for creating the claws. Once the basic shape was on paper, Nate traced around it onto a piece of wood that he had cut to 1″ x 13″, which was the calculated maximum length of the claws.

This length was determined to be the longest length that could fit on the back of Nate’s forearm. Once the wood had been traced, Nate gathered up his aluminum and headed to his Grandfather’s barn, where he cut the wood out on a band saw, sanded it on a vertical standing belt sander, and used it to trace out the aluminum claws.

The aluminum claws were then cut out VERY CAREFULLY on the band saw and sanded lightly on the belt sander. The next step was to put each claw under the wire brush wheel to give them a “brushed aluminum” finish, which Nate determined would look closest to “adamantium”, which Wolverine’s claws are actually made out of.

The next step was to mount the claws to a ball-bearing track that could be hooked to the back of Nate’s forearm. The track was created from a sliding keyboard tray. The slider on the track was modified to be much shorter, and use only 8 ball bearings. Bolts were put through the slider on the track and then some galvanized metal was bent and hack-sawed to make the right shape for attaching the first claw. This required drilling holes through each galvanized metal pience and matching holes in the first claw. Once the first claw was fitted to the track, 2 other claws were then drilled to match the first, and 3″ and 3.5″ bolts were used with nuts, split washers, washers, and locking nuts to to space the claws apart and keep them tightly affixed to each other and subsequently to the track. Once this was complete, screws were added through the bottom of the track so that the slider could not slide out of the track (to avoid killing innocent bystanders). Pictured above the the fully extended claws on the track.

The next step was to create a way to attach the tracks to Nate’s arms. …and Nate thought growing facial hair was hard! The eventual solution was to cut fabric left over from creating the pads for the X-Men suit into harnesses for the claws. The piece under Nate’s wrist buttons into place so that the claw tracks can be held VERY tight, but still be possible to put on. The fabric was sewn to the tracks through holes that Nate drilled in key locations.

Yep, those are definitely claws! …on sliding tracks, nonetheless!
