- When I first started the Scorpion Crawler build I didn't know much about roll cage design, but I learned a lot on the way. In this video I'll share with you 17 tips to build a better roll cage.
Roll Cage 101:
•Roll Cage Design depends on your specific sport.
•If you intend on racing, get SCORE book or build for your specific racing guidelines.
•Don’t build a roll cage just to protect the body… that is not a roll cage, a roll cage is for the occupants safety.
Tube
•Welded (aka) HREW
•DOM- Drawn over Mandrel 2x the cost of HREW
•Chromoly?
Size
•1.75” .120 wall standard for Jeeps/Buggy's
•Triangles are used on bridges for a reason, use triangles, not fancy curves or plain squares.
•Avoid Bends, if you have to make a bend, think about a support at the apex of the bend.
•A tube should never end at a T on another tube, an impact will just bend the other tube.
•Gusset corners with triangle plates or an A shape of tube for strength.
-What is an A,B,C, and D pillar?
•Try and keep A&B pillars vertical and top leaned back too far… which will weaken the structure.
•Ingress and Egress
•An inverted V is the strongest type of windshield spreader.
•The B hoop should have an X in it for support and a horizontal bar for your harness.
•The top of the harness bar should be about level with the top of your shoulders for safety.
•If you have multiple joints coming together, weld each tube first before adding the next tube.
•Attach seat belts and seats to the roll cage, especially if the roll cage is not welded to the frame.
•Consider bars over your head in case of a rollover onto rocks and trees but also keep plenty of headroom.
•Consider what will happen if you pass out and arms and legs start flailing.
•All tubes should ultimately connect to the frame OR be welded to sandwiched plates to a solid point on the body.
•If welding to the frame, consider a landing plate to increase weld area and strength.
•Tube splices should always be sleeved and rosette welded, not just butted together.
•Put thought into impacts and try to visualize where the stresses will travel.

Solid video here. I can tell you put a lot of time and thought into this one. Broken down into key points and lots of real world examples really sends it home.
Thanks Man!
I guess Im quite off topic but does anybody know a good place to stream new series online ?
@Zane Zakai flixportal xD
@Zaid Korbyn thanks, I went there and it seems to work =) I really appreciate it !
@Zane Zakai You are welcome =)
I picked up a Wrecked first gen sequoia. This is kinda what I'm thinking of doing to it. Car was practically free and I can part out some stuff to put money back into it. Thanks for the walk around so I can get some ideas of how to start.
I love all of the builds but I think Scorpion is still my favorite. Its so custom, shows the true abilities and genius of its creator
I'm considoring a budget competition truck, and this video was really helpful in explaining how I can make my roll cage stronger and safer.
this is a huge help - very clear and concise - the illustrations and teaching aides helped make the points easy to remember- thanks!
In 20 years of car ownership ive never been stranded more often than with my XJ. However, I still have it😲
Incredibly informative. A rare gem on youtube.
Alot of respect. You take long time to explain and go into detail helping me alot with my Baja bug build
one of the best vlogs yet..thank you for sharing..take care.
Phenomenal information. YOUR VIDEOS ARE SO HELPFUL. and the details are explained perfectly. greatly appreciate the work and effort you put into these. THANK YOU!!!
Thank you for this video. I am building a Baja Bug now and in process of caging. Your key points are spot on.
I am familiar with this and I think you explained the finer points of cage fabrication brilliantly. 👍🏻
Very well spoken, clear and direct. Your patient and methodical in your presentation. I am not in to this kind of activity and I was amazed at how well I understood and how much I learned. Thank you for doing an awesome job. 👍🏽🇺🇸👏🏽
Great video as always! Can't wait to start my cage. I'm in a wheelchair so getting out fast will be my only issue. Ejecto seato!
I appreciate your content, I've been binge watching your channel for a few months now, great job ,, keep it up!
Excellent, Actually trying to build my first tubular jeep and your video helped a lot
Thanks so much for posting this video! I'm about to do some cage work to my own 1997 XJ and this has helped me out so much on the planning!
Great video. Im about to build a cage for my JK. You really set me in the right direction. Thanks a lot.
going to do my first cage soon , this helps a lot. Thanks.
Awesome video and full of good info for someone getting started. Thanks!
Very nice! I really like the clearly illustrated examples.
Great vid and solid factual information! I love how your videos give the average guy the confidence to tackle most things they wouldn't think possible. I know they give me the confidence to try anout anything.
thanks for the comment bro!
Love the videos, you're really good at hitting main points and explaining things concisely and effectively. The welding wire examples for stresses and geometry were awesome too, keep up the good work :)
thanks man!
Such a great tutorial on how to build a very strong cage. Really enjoy learning from your videos. Bummed we didn't get to say hi again this year at sema. Maybe next year. Appreciate the knowledge.
Wow, really nice instructive video, You are basically now a Roll Cage Architect, this video is a most see for all peoples that want a roll cage.
I wouldn't say that... but definitely I know much more than I did this time last year!
Dude this is soo gd helpful. It gave me a lot of insight for my 94 Dakota.
i was worried what would happen after you finished your project. but your scorpion was finished, you have not started a new project yet, and your videos keep going with amazing content !
always amazing content here on bleepinjeep !
THANK YOU!!!
Great video. Good information that is going to help me finish up my cage. Thanks.
Insightful video! Thanks.
Right now I'm trying to design a hybrid cage for my Wj. Hopefully I'll start on it next winter. Or I'll do all the internal components this spring.
bro thank you so much its been really hard to find specific in detail about roll cages
I love the little visual aids you use props
amazing video..nice tips as Always....great work...thanks my friend
Great info on roll cages, in practice and not in theory!
As usual!
Another great video!
wow - so cool info - thanks so much mate - appreciate it LARGE!!!
Best video so far thanks for all ur info
The design is mean. Great video content. Hope to see more Design Class videos from you. I wish I could drive one of these. 😉
Definitely solid information and useful.
great ideas and points👍 Thx.
Really great video! Learned a lot!
Awesome video as always!
Excellent information man, a great place to start for sure!
thanks
this is by far my favorite video you've ever made 2 thumbs up
we need more thumbs, 2 just doesnt sound like enough!
BleepinJeep but I only have 2 thumbs lol
Great video, thanks!
Another great vid, I'm blown away the quality difference between the scorpion and your last XJ
The hope floats was great quality IMO, just built for moderate wheeling as opposed to this one.
Sorry, I was referring to your XJ with the dovetail front, to me that was your last hard core rig
Trae Miller
That's because Scorpion is a Jeep-born buggy crawler. Hope Floats was a Jeep.Two different rides.
Nice work Matt. 🤘
ahh I see, ya that one I had for over 16 years and it slowly evolved over time... it's much harder to build it right that way. Defiantly makes things better when you can plan the rig from start to finish and build it all within a shorter time frame.
Matt does refer to his dovetail XJ as a crawler, I just noted that his workmanship was much improved in the scorpion
Great tutorial Matt! Couldn't have come at a better time too since I'm about to build a cage for my XJ.
glad I could help;)
This was really awesome.
amazing... thanks for giving to much information...
Great information. Thanks!
Yea he makes really good videos on. Everything but Matt u should really make ur cheap jeep a Zj and keep the full doors and everything so u can make some wheeling videos in the winter out in the snow that would be sweet and I have a zj and would just like to see what u would do with one
That Bleepin Jeep plate drop at the end woke me up. You should put it in the video in random spots to keep the viewers awake and on their toes.
Exelent Matt, Thank you.
awesome dude So much info. Thx
Great video. Thank you
Great info.
very good video helps me and alot others also
Great stuff thank you.
Awesome tutorial you made great points. Class dismissed...
I live in East Tennessee we can drive utv and buggies on the road I am building my house right now (mountain living) is my RUclips channel but I'm going to build a 4×4 buggie for the road after I do my shop this video was a lot of help thanks by the way I think you did very good on the info
Thank you great video
Awesome video
You have such a soothing voice
Great video keep it up
Thanks lots good info on a roll cage
Bleepin Jeep, you should do a video on how to repair chipping roof paint on an xj. That seems like a popular problem. Thanks.
awesome video
Nice video. Subscribed!
Matt, that beard makes you look like you're amish lol
Super helpful thx!
this is a very awesome car
Matt this is a great video very informative. You showed us how to plate the frame at attachment points,but could you also show the best way to transition from frame to cage . looks like you went from frame to tub to cage? Thanks Matt
+david sandberg weld a big flat plate onto the frame and weld your tubing to that.
When tying the cage floorboard plates in, when you weld in the plates to the frame, never weld all 4 corners to the point of them being a full wrap weld. At each corner, leave about an 1/8"-3/16's on the corners not welded. A hard impact can cause the unibody to crack around the weld. At this point, it will just connect the dots to the point of the cage plate coming off the Frame.
great video ! i sure did enjoy it , only thing is is that we never wear seat belts in our buggies. our rigs are a bit different than most but we also ride in ALOT of spots that are cliffs on either side . so in the unlikely case that we roll we need a chance to jump out before we roll off a 150 foot cliff .
I hope thats a joke...
BleepinJeep it's really not ...
thank you
cool. thanks .
I'm sure someone has already said it but the spot where multiple tubes meet is called a "nodule".
I have a few questions here. #1, in the areas like against the roof, how do you clean the weld splatter; and #2, how do you paint those tight areas?
Did you powder code the cage? Or spray paint if so what brand of paint and process thank you.
chromoly is usually used for applications where weight savings is important like aircraft, formula SAE and Baja SAE, which is what I do. It's not any lighter than welded or DOM but it's stronger so you can use thinner wall and smaller diameters
good to know!
I'm about to purchase a bronco and am thinking about doing an exo cage/skeleton. what advice do you have?
I have a '92 Wrangler YJ, 2.5l 4cyl.. I just bought a new starter recently because of the same thing.. It left me stranded at the park but all of my lights and everything else worked. I just had oil in my starter, but I fixed the leak. This time, it blew a 50 amp alt pwr.2 fuse and also the 10amp I.O.D fuse as well.. I replaced them, and now nothing comes on, my headlights, guage lights and even my guages dont work. I've tested my battery and its not dead. I tried crossing the poles on the starter to try to start it, it acted like it wanted to crank but it started making a sound like boiling water makes so I unhooked it from fear it'd catch fire. Any suggestions? I need help as soon as possible. I've already checked my fuses and relays and they're all good. Another question, if it was my starter.. how could it affect my guages and lights the way it did.
One of your best videos I need to make a cage when building my XJ. Most people I've talked to say do a combo of internal and external cage do you think this is best?
Ya you need both just like on the scorpion to make it strong
BleepinJeep awesome thank you for the help
Very nice, beyond a poor mans wherewith all.
9 people like square designs
0:48 that JKU being a mall crawler as intended by the Chrysler gods lol
Im just trying trying to figure out how to make a mini truck safe for commuting lol. Looking at building a daily/ overland truck...
For where there is a bend should u fit and weld plate metal to it?
How many feet did you use on this build? I’m curious to compare before I buy
Geometry, physics, Numbers and the ABCs, man I’m getting so smart
U keep saying 2" .250 wall for links but that'd be 1 1/2" od instead of 1 1/4". Or am I missing something? I may be wrong cause I havent used tubing much. Is it 1 3/4 .250 wall dom? Love watching!
You are so cute, and you have the most amazing videos! :D
Stadium x rock climbing.
A full cage to play a major part of the chassis strength is different to a safety cell for the driver. I want both. A safety cell with the external cage for the body built off the cell
How do you reccomend tying an interior cage into an xjs frame rails? I've seen guys on pirate do the plate to the body and then from the underside plate come over to the frame rail with a piece of tube to another plate.
that sounds like a good idea, or possibly just cut a hole in the body and come down to the frame rail... but your other idea might be a bit stronger. Just make sure to add frame stiffeners first or something better to weld to than the original frame rail.
U drop that bleepin jeep sign at 19.00 again on me and im gonna shit in your garage instead of my pants. Lol. Take care. Good stuff.
Cant we just wrap ourselves in bubble wrap? Seriously , awesome video very informative.
for solid tubing id suggest 4130 chromally steel. its what I use for bmxing and the tubing is damn near impossible to dent for slamming into a concrete or steel ledge every once in a while and the frame was a 2009 special still going strong. my last bike was an aluminum frame and the whole head tube snapped without warning not even a year into just learning how to do some basic tricks and I'm only 160 pounds wet so that frame was garbage lol
benson420710 BMX is way different then rock crawling in rock crawling you take way harder hits so what's good in BMX ( where you need strong and light to do tricks) is different then rock crawling (where strong is more important then weight). Now I'm not hating on you I'm just pointing something out
I understand where you're coming from for the fact one weighs 10 times the other ,now I'm wondering how those 15-20mph crashes into concrete and steel ledges compare to rock crawlings slow but heavy impacts. ive seen the same parts on different bikes survive being ran over and it really matters how good the forging process is, in my case 4q "deathbaked" 4130 CrMo thats not even 4mm thick and you could use a 16lb sledgehammer to barely leave scratches. I do not know honestly that much at all about building a cage but more of what metals can stand from stupidity
benson420710 your comparing apples to oranges
The tubing he's using is steel. I don't think people make roll cages out of aluminum.... it's much softer than steel
How do you replace the front window?
what welder is better for this type of job or just doing some work on the xj
I use mig but tig is the best and strongest for tubework. if you're looking for a beginner welder check out our review on the hobart handler, its a good welder for beginners: ruclips.net/video/JWfxqHtXZEU/видео.html
I am taking part in Baja ... so r u gonna help me out
what year xj should we buy ?
