The epic costume requires much preparation.

Inspired by the designs from supernatural themed movies these stilts are metal and plastic which makes for a safer and longer wearable appendage.

All of the computer generated templates and drawing files are located in the digi.rar file on the materials page.

I recommend that you download and read this entire instructable before beginning your project.

Build early so you can practice and get used to walking in these stilts. Play safe...

You can download the complete instructions in 2 parts in the materials section of this instructable.

I spent approximately $120 to build these. Expect the cost to be between $100 and $200 depending on your local materials availability.

The stilts shown weigh about 8 pounds each.

The stilts pictured were tested thoroughly bay a person weighing 200 pounds plus carrying an additional 30 pounds of weight.

NOTE!!!!  To make up for the lack of video I am offering a 1 year PRO membership to the first person that posts a video of stilts based on my design.!!!

Important Notes
 
If you are making your own straps then you will not need the pre-made Velcro strapping listed above. The pre-made straps are available at Home Depot but are weaker and considerably more expensive than making your own. I will cover how to make your own in a later section.
 
If you are unable to find the 1/4 by 1/4 Bolt bushing spacers then you will have to make your own from 5/16 inch steel or copper tubing. You will need a tubing cutter or hack saw for this. I will show the steps to make your own.
 
Sintra is available at plastics supply stores like Industrial Plastics & Paints. (ippnet.com) There are other plastics available like nylon and PVC but they are a great deal more difficult to work with. Sintra is foamed PVC which is light weight and has the strength required for this project. It is easy to cut and form.
 
The metals are available on-line from metalsupermarkets.com. If you go to the store be sure to check for pre-cut and scrap pieces which will be less expensive than the full lengths of bar stock.
 
Bolts and fasteners are available in specialty stores like calfast.com
 
Nylon webbing, Velcro and Tri-Ring are available from paccana.com or hudson4supplies.com
 
Big Box stores like Home Depot may have the materials listed here but the prices will be quite a bit higher than the specialty stores.
<div> <iframe frameborder="0" height="315" src="http://www.youtube.com/embed/CrtPkodh5Qw" width="420"></iframe>HERE IT IS! THE VIDEO YOU'VE ALL BEEN WAITING FOR!!<br> <br> i made the stilts based almost exactly off these instructions (only i bought them) &nbsp;I made them for almost no money between the tools and materials i have, and scrap from work (sintra and some metal)</div>
<p>Is there a possibility to add more to the base of them? I am making a Krampus cosplay replicated from the new movie that came out in Dec. and am wanting to make sure I have really good balance. I am also going to be adding large hooves to them with fur. Also, is there a way to give them a bouncing ability? I want to be able to have some jogging/ running ability in them in order to chase people and, when needed, get around a little faster. He also has an amazing jumping ability and I kind of wanted to be able to do that in them as well. Any help is appreciated, thanks!</p>
That is amazing. You all make me wish I had this type of talent. When I try to do metal work it just falls apart in my hands. I tried to make stilts like this and ended up crying and going back to clunky frikkin wood
Fantastic work, but it kinda looks like trying to walk while drunk. =D Kidding, I know it's difficult to walk in them.
Yeah, i've gotten better and ill have a few more videos in the future, but this was my 2nd time on them. My first time was only a few steps before the &quot;crimp&quot; gave out. broke down and bought the correct tool for 20 bucks. <br>
excellent work!
oh, and i originally tried making the steel bars about 6&quot; longer to give me more height, DONT DO IT! it puts your center of gravity way off its almost impossible to get up into position with that, and if you get up, you wont be for long. the length in the tutorial is probably the longest your going to want to go.
<p>downloaded the pdf files, thanks for the drawings, that was the only part that was actually speaking my language to where i can write up a lay out to fabricate the parts for the support braces. i do however plan to use steel rather than aluminum. and for the leg supports instead of the plastic i want to use steel as well with a foam backing for a tighter fit when strapped.</p>
<p>can you use 2x1 steel or does it have to be 1x2? </p>
I have some question for the designer .My husband is a double amputee above the knee. We are low income and because of that the legs they wanted to fit him with were very crappy.But thats our goverments medical. But I am looking at your and I, m wondering .I see you have a shoe type thing .Which he would not need .But we were looking at your plans and seeing if they can be used without the lower part of the legs.With a amputee like this all the weight is put on the theighs and hips .any idea,s on how to mybe make this work?
They need to put a suspension sys in to the design to help absorb the impact of walking
<p>Great build, but you're missing an awesome opportunity. These could be 'spring loaded' allowing you to jump like Jumping stilts. (no longer just a costume). </p><p>Extend the calf-bar past the knee joint about 3 inches. Then connect the 'heal' to the point forward of the knee with a spring or strong bungie cord. </p><p>You may need to raise the toe so you can fully extend the knee. </p><p>If the spring is strong enough, you'll have to actually pull yourself down then jumping will be augmented. </p><p>I've had this design in my head to two years... just haven't built it yet. </p><p>-Matthew</p>
<p>You need to build this. Just bear in mind thar I have wrenched a knee, fractured an elbow and severly twisted both of my ankles at the same time while testing to make this design.</p>
<p>Random_Canadian,</p><p>I've always loved this instructable and check back often to see the great builds you inspired. I'm long overdue for this comment... I have a suggestion on a variation for those interested!</p><p>Several years ago, I set out to make a very similar design, inspired by special effects studios' work for various movies. The actors who used those legs complained of discomfort and fatigue caused by the improper alignment of the knee joint on the stilts not aligning with their actual knee joint. </p><p>I know many people who've had knee reconstruction (I have very active friends!) - all were able to delay knee surgery as long as they could by using semi-custom leg braces that look very much like the upper part of this stilt design. Additionally, the mid/lower portion looks much like ankle braces used by other friends. I was able to get many of these braces from my friends when they stopped using them. I have also seen them at local non-profit stores (although, it may be best to leave these for others with a true need!). Using these, I was able to build similar stilts, bypassing much of the raw build requirements of the structure (aluminum bars, joints, foot beds, sintra parts, etc.) and having adjustable and perfectly aligned knee rotation. </p>
<p>Love your work. the cat is a nice touch. Your ideas are great. Thrift stores around here are seriously lacking in anything awesome. I do occasionally find raw materials but have to check daily almost hourly for the truly awesome. </p><p>I have been working on an updated design that needs to be removed from my circular thought patterns. Mind like a bag of cats and all.. </p><p>Anyway... check your inbox!</p>
<p>PLF, that's how I roll.</p>
<p>I am in the process of building a pair, but I have encountered a measurement problem. On the length of webbing and velcro required, is that per leg? I worked on 2 x 16 inch + 4 x 10 inch = 6 feet, and that is for one leg only. Am I misunderstanding something?</p>
It is possible that I made a mistake in the directions. It is best to check for fit using a cloth measuring tape the go from there, that way you will have less waste and a more custom fit.<br><br>Good luck with your build.
<p>Finished my first build! Thank you for the bulk of the instructions!</p>
<p>You are welcome and those look spectacular. Great job! check your inbox</p>
<p>do you still do commissions on these? cause ve been looking to buy some EVERYWHERE how much do you charge? email me- schreebles@gmail.com</p>
<p>Hello! </p><p>I am looking at these wonderful and perfect stilts to make General Grievous from Star Wars. I am having slight trouble as in I am really struggling to find 1.5 Tri-Rings. Is there anything else that can work?</p>
<p>Are you in or near Calgary? Try Paccana if not. a slot ring will work. You just need to make sure the straps are tight to prevent injury. there are several bend back rings that will work. also if you are having trouble with the plastic, I recently found that regular ABS sheet is now less expensive than sintra at my local supplier. It's a little harder to work but has more structural integrity.</p>
<p>This is fantastic. I'm definitely going to need this for this upcoming Phoenix Comicon. (6 Raptor costumes...What was I thinking volunteering for that?)</p>
<p>The only issue I have, is finding the stuff in Europe. I'm in the UK now and though they do inches at times, they mostly use metric. I've discovered that 1/4' = M6 and 5/16 = M8. The others I'm still trying to figure out. Other than that, I can't wait to put this together!</p>
<p>I agree with the metric thing. Canada is essentially US junior when it comes to construction. Metric is awesome, Base 12 WTF is that. how many inches in a kilometer? Seriously don't get me started... My supplier is now selling sintra as 6 mm but at an astronomical markup fro before. almost $200 per sheet from $45. </p><p>Otherwise I am looking forward to seeing pics of your build!!!</p>
<p>It's called foamex here, and will take a look at it. But we may have other materials that are similar in strength. I'll ask in the workshop. And when it's done, I'll let you know. </p>
<p>You can use these stilts for an Alien costume ( alien as in Alien vs. Predator)</p>
<p>Awesome! Questions! So I noticed on the videos that the surfaces you walked on were grass and carpet (good surfaces for grip). How hard is it to walk on smooth surfaces (restaurant floors and cement). Did it make you super nervous? Are there any grip recommendations you have for the bottom of the stilt foot?</p><p>Also I'm still reading the instructions but I think I'm going to attempt making these. But before I spend hella money are there any obvious tools (outside a basic tool kit) I'll need that you haven't mentioned? Pretend I only have a general basic tool kit and know nothing of shop outside of the context of my (decades ago) fifth grade class. Also anyone have an e-mail (fb messenger, whatever) I can ask questions to in case I have a question that none of my strapping young lad friends can answer? </p><p>Thanks! </p><p>~T </p>
<p>This is really cool! What depth do the tee-nuts have to be? Also, do the turnbuckles absolutely HAVE to be over your weight? I just bought two that support up to 130, which is exactly how much I weigh without gear. I haven't been able to find anything stronger than that with those dimensions, so if I need to get stronger turnbuckles, do you know a site with those specifications? Thank you for posting this incredible tutorial!</p>
The T-nuts should go all the way into the aluminum for maximum shear strength. they should also be a friction fit to prevent a loose, weak joint. I usually go over the rated limit of any mechanical item just to be on the safe side. In practice most manufacturers over-design an item then set the failure limit to be much less than the average tested failure limit, this is to allow for manufacturing inaccuracies and a safe working load. Further, you can eliminate them altogether with a short piece of cable if you are not going to adjust the stilt height. Note that the cable may stretch over time but it shouldn't be too much. Just make sure to use cable strain relief eyelets to prevent a bend point which can greatly weaken the cable. In the time since I built these, prices have gone up astronomically and availability has dropped off to nothing in Calgary. So that may be the way to go. <br><br>Also I have noticed that Sintra has gone from $40 a sheet to $160 a sheet. With this in mind, standard ABS sheet in 3/16 inch thick will work, it is just a little more difficult to form but it is more rigid. <br><br>Thanks and good luck with your build.
<p>Thank you! I actually found some 12 x 24 sheets of Black 6mm Sintra on Amazon for only 5$, which is amazing compared to these extremely high modern prices. I'll try ordering one to check it out, and order more sheets as I need them. I also found some 800 lb stainless steel turnbuckles (Via McMaster Carr, they are over 16$ though). Expensive, but they seem like an easier way than the &quot;buckle-less cable&quot; option.</p><p>Using what you said, I've narrowed down the 1/4 20 t-nut depth to be either 7/16 or 9/16, which were the available depths in the store. Would one of those depths be enough?</p>
<p>Only improvements I can think of is maybe adjustable foot clip so people with bigger feet can use it (I'm like a 13 and a half) and maybe use some old tread from a tire to cover the footcups, as to not scratch floors and give more traction.</p><p>But otherwise, Looks awesome! I really want to build one!</p>
Thanks. The foot pad was left unfinished to allow for the placement of custom footprint grips.
<p>The price of Sinatra has skyrocked in the past couple of years. I am now looking at $180 per 4X8 sheet as compared to $15. The plastic leg brace pieces need to be rigid and easy to form. ABS will take a little longer but still remains reasonable in price. ABS and PVC plumbing pipe can be cut and heat formed into proper shape but it will require more time and a better insulation layer than just denim jeans.</p>
<p>Hey, I just finished mine today. Still gotta add all the faux fur and other details. Thanks so much for a great tutorial. I also designed and built a mechanism that takes rotational motion from my leg and transfers it into swinging motion for my tail. <br><br><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/UbDekWGjuzY" width="500"></iframe></p>
<p>You have done an awesome job. Keep up the great work and check your inbox!</p>
Thank you for the instructable on these! Made a satyr for a makeup demo using them! They turned out amazingly well!
<p>Superb! check your inbox!</p>
<p>instead of the Sintra, could I use thick leather? Sintra is difficult to find in my area.</p>
You need to use a rigid medium. This will prevent injury.<br><br>Sorry for the late reply!<br>
What is the price per set?
How about you use this idea for prosthetics for the military
<p>Hey there, I'm 6'5&quot; and 300lbs. I am needing some digitigrade stilts for a costume I'm making, however due to my already large height, and a max target height for the entire costume of 6'9&quot;, I can not afford to have a foot of height added. My questions are, would it be conceivable for someone of my stature to wear a beefed up version of these, and would it be somewhat safe only having at the most 4 inches of rise?</p>
<p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/XVZL3MxF0tY" width="500"></iframe></p><p>Hi...i wrote to you a while back asking for some details on your design, which you answered....i finished the build and we started using them in shows...i wanted to thank you for your help and i made a video for you to see what happened...you said you wanted to give a membership for instructables if someone made a video of the design...if that is still possible i would love one....thanks again..Scott</p>
Fantastic work. It is great to see that this is still working for people. Be sure to check your inbox...
<p>by the way...this build cost a total of about 30 euro, since i didn't have money and used a lot of materials i found around....like tubes of aluminum with wood inside smashed flat with a hammer for the leg supports, garden buckets in layers for the sintra, the bottom of the foot is cut from an old car bumber(steel) with a piece of old motorcycle tire over it, the strap holders are cut from the abs plastic from a car bumper(lucky there are broken down cars around me) inside the leg holders is thrown away beach mattress....also the bottom rectangular structure is aluminum instead of steel, which helps to arrive at a 2kg per leg total weight...i just had to buy, bolts, straps, and the cable assembly...i never found nylon washers and just went with metal, it was ok like this....thanks again for the blueprints for this...it would have taken me so long with trial and error to arrive at a working construction...Scott</p>
<p>Hi, first off all let me thank you for this magnifient instruction.</p><p>But I also have some questions to you. </p><p>1. I live in Germany and i want to buy such Sintra plates but only found some for 400 dollar and more +shipping costs. Please can aomeone give me a link to a Sintra store in the EU?</p><p>2.I also found American stores for metall like this (you know its too expensive). And again please can someone give me a link to such a store in the EU, too?</p><p>I thank you for the Information...if there will be some...and wish you a nice day.</p>
<p>For sintra I used PVC tubes, with the righy circumference to make sure I can make the leg panels.</p><p>I used a gas heated barbecue to heat my panels (use welding gloves to hold the pvc) and carefully soften the pvc to a flat sheet, draw your plans on them and heat again to shape around your leg.<br><br>since I work at a blacksmith, I didnt have trouble to get steel (I made all the leg sides out of steel) and the foot base I used high quality tropical wood from a carpenter. (easier to fit my big feet on)</p>
