Man this is still my favorite video of yours to date, id love to see you put out some more fabrication videos, keep up the good work
Wow dude my mind is blown! I watched a couple of vids before this but you took the subject home for me. It's cool that you share your knowledge like that. Thanks!
Chaps' Unlimited
thank you, I learned something new today, and loved it, very cool, smash that like people!!!
I am over impressed! You are a master at Your craft. thank You very much for putting up such an in-depth tutorial of Your methods.
Wow, this video is awesome! Thanks for sharing your hard work and methods. I'm excited to try them out.
Awesome- you covered a lot of great info- I have a little mig welder that I use for basic repairs but I may look into getting a cheap tig. Thanks much!
I've done cad, and builds of many things, nice to see someone else has also CNA operator and and presses
For regular carbon steel I just used the standard filler rod from the welding supply shop, 1/16".
Great video. I would like to recommend using less heat on both the oxy/acetylene and tig welds. The silver solder will flow better at lower heat and won't require clean up. Overheating the metals causes oxidation and makes for a poor weld.
This is sooo cool. Really impressive, and it looks like so much fun.
I WISH I knew CAD!! I'm an Old Fart, and don't see it happening.... but I can Weld. What you're doing is really an art form of sorts. I thank you for sharing it!

Cad for dummies??? It works
Very nice video and well explained. Inspirational as always!
Hey there Harley, as a tig welder I wanted to chime in. You should wire wheel mill scale off your 3/16 rod. Gtaw processes require super clean metal an the mill scale is contaminating your Welds from the get go. Same goes for the paint on you frame to rod weld there. Try cleaning your metal at least a half inch from your joint each way. The metal flow will be much nicer an the brazed welds will have no competition on your tig welds. It was a nice video an I would like to know more about the Autocad programing like cost an what to get. Thanks an keep up the good work.
Yes 3/16 is fine as I did
There's a lot of really useful info here. Thanks!
great video...got my ideas flowing!! thanks
This is awesome!! ‘And things like that’
great how too video hope to see more on this build big thumbs up
Awesome video, your bloody brilliant with rc's
DUDE THIS IS AMAZING!!!! Thank you so much!!
Good stuff. Nice explanation. Great video man. Heads up. If you drill a couple extra holes on the venders leverage arm. You can get much cleaner and more accurate bends. What you want is the bending arms pin that pushes on the rod to be as close as possible to the pivot
cool vid love the one's you have made!! have to make a rock bouncer for my next protect
Thank you for putting up this vid. Very informative. :)
Nice build! I got the Thermal Arc 95s two weeks ago and I do not know what filler rod to get. And I am welding a 1/4 chome-moly tube chassis.
thats a cool piece of work
i use mapp gas torch and brazing rods rods come 3 feet long covered in flux .my way is alot cheaper but not as clean as those i sometimes have to grind down the joints. love the bender i wll have to pick one up cause i use a hobby hand bender and cant seem to replicate the bends very easy .Thank you very much for this vido had wondered how you dd such good work
Thanks man. That was great Info!
Very nice job thanks for this video....
Thanks for the great tutorial, I'm going to make a fast back cage for a class one jeep wrangler Rubicon, I'll also be using 3/16 steel rod. Just had a quick question, what vice are you using, cause I need a vice to hold that BAC inc. bender, thanks
Thanks for sharing this!
hey harley, great video. I am about to start brazing my first 1/8" rod cage and I had a question. How do you manage brazing junction of tubes? Is a welding magnet the best option? thanks very much
Great tutorial. I noticed you didn't mention anything about mitering the tube/rod joints. Is that not an issue? I know from brazing bike frames and from doing some practice work with brass that you need to get a good fit; especially if one goes the brazing route.
If you want to try something new, try to down load the student version of solidworks. It's and excellent 3D modeling especially the weldment part. I used a similar program to model a complete trophy truck in a previous job.
Thanks this will help!
Hey dud ..nice ..!! Since im an aerospace welder i will take advange of of it ..i wil make it out of titanium tubing
Yes the templates will be uploaded soon.
Maybe in honesty Harley;
Mention to the young guys arriving here that your adding a roll cage of your design on top of a commercially available retail R/C chassis[Note the black parallel frame rails]There is a big difference there between 'modification' add-on and a full chassis build
If you young guys are frustrated with brazing/ soldering problems: Mow some lawns or shovel mums driveway for funds to purchase a small wire feed welder that uses normal household current. A Chinese 'buzz box' will join this small rod or tubing together and cost is about $100 or 55 quid at the discount China tool outlet.
Resurrecting this one from the dead....
hey harley,
ur design r very awesome but i m stuck with the circuits for servomotors and rc control..
can u share d details...
Love it great video and great technique on all of the different methods🦾🦾🦾🦾🦾🦾🙌🙌🙌🙌
Good informative video. You must have the patience of a saint. I have just been looking at the comment's on this video. A good 30% are asking questions you answer in the video or if not it would take very little time to look it up on Google. Do you sell these or are they for your own collection?
Do I sell chassis's? Not normally, I just build them for my own rigs mainly.The questions are frustrating at times :)
good and informative video:) good work, and please put the templets of this on your web site?
Very informative - I have used the old school stick (arc) welder in the past for this work - joints do not look as neat as yours !!
Have tried silver soldering with Propane only torch with mixed results - I might keep trying after watching this, cause you don't seem to have a really hot flame with your oxyacetylene torch
Awesome video! Very informative. How heavy is one of those roll cages?
It really depends on how much bracing is used. A couple pounds isn’t too unreasonable.
Think you could do a video on your process on putting together the chassis together?
Hey Harley would a MIG welder work for doing some tack welding on the tubes and then using solder to fill and finish up the weld? Or would a MIG work for doing the whole chassis? My dad has a MIG i could use.
nice vid man !!! have a question were do you get those tubing? whats size is thats tubing
I want one of your steel setup plates (the plate with all the holes)
A stick welder just won't get it done, unless there are some really specialized electrodes that I'm unaware of. However there is a method to convert old arc welders into TIG welders that you may look into.
Where do you get your tubing?I am thinking of getting into building chassis for all of my 7 rigs.
So is it really easier to use a CAD software to map out your build? How long do you spend making the design typically? Also sorry if I missed it but what program do you use? Auto cad?
I've never used chromoly tubing so I can't say what would be the best choice for that.
I have an old Stick welder, could i use that or shud i upgrade?
hey how can I get your rock bouncer type of design I wanna make a cage for like a slash 4x4 front and rear axle or for a pair of clodbuster axle set. just a way larger scale maybe
1/8
Thanks, but what filler rod do you use?
I have several questions cause im new to brazing. I got the templates, and my tubing and a bottle of mapp gas and for the life of me it just dont get hot enough for my brazing rod to flow. So my question is do I need to add oxygen to the mix? And will a jewlers torch get this hot enough? Please help im just a 44 year old kid that really wants to build this.
Good info :)
What CAD program do you use?
Hi Harley, great tutorial! I'm a bit of a novice in the steel fabrication department so I've got a question regarding the steel wire that you're using as I am looking at building myself a rollcage as well. The question is, are you using stainless steel or "normal" steel, or is there a specific grade that you'd recommend? Please let me know If you have a chance.Love your chanel, keep up the good work and cheers from down under.
+waffleattacks I use standard hot rolled steel most of the time. This is nothing special, standard cheap steel. Stainless is actually more difficult to weld.
Harley Designs Thanks for letting me know, I'll give that a go. Cheers
Hey Josh was wondering where did you get those red magnet braces that you use to help hold the tubing to the truck while you weld? Thanks for your videos learning a lot.
Harbor Freight, super cheap.
You don't always need to use filler rod for tig welding.
I revisited this video since I'm getting into brazing and my wife got me a little torch. What tip size do you normally use? Thanks for the great info.
I don’t recall the number I used on this set but it was one of the largest.
harley, what program did YOU use for this video?
How much would charge me to build a full cage for my 4runner body on a scx10ii frame with my full interior?
What material can be used for cars
Less weight and good strength
Budget price
What company make that bumper mount
thanks!
As far as I knew you could only solder copper.
Would you be so kind to tell me whitch kind of metal the rods are made of ?
What CAD program do you use
What website did you use for the lines
link to the buildlog for the original truck?
Are you using solid wire rather than tubing such as brake line?
Is it hallow or is it solid
could i make a rock bouncer with the cheap metod?
I'm looking at getting into building scaler chassis for myself. I'm gonna go with silver soldering. My question is, how well would silver solder paste work? from what I've seen I think it would work perfectly for this application. I am specifically looking at the muggyweld.com ssq-6. It has a strength of 70,000 psi and can be done with a mapp gas torch. What are your thoughts? Paste or do the classic silver solder way?
luke stowell I have never used the paste but I have seen it recently because my GF would like to try some jewelry soldering. 70,000 PSI should be plenty strong. You can use the traditional silver solder I use with a MAPP torch as well FYI.
what shielding gas would you use for tig welding brake line tubes ?
i have a tig welder that is currently set up with pure argon and i have a mig with c25...
Pure argon is all I use on my TIG. C25 won't work in a TIG but I do believe you can run Helium as well, although I don't know the benefits.
Could this have made with brass tubing? Great video!
People have built them out of brass before but for a truck that gets used I would not suggest it. Brass is very soft and just doesn't hold up.
Thank you. Look forward to your next video!
🔥
Would you try MIG with a cage?
I'm asking you is imprimeron diagrams for cutting and bending the rods to the tubular esctrutura I see in the video that you have some sheets with parts
They are on my website, HarleyDesigns.com
Hello Is can you tell me where to get the small hobby grade pipe onlineThanks in advance and do you still buy RC cars cars I have a twin hammers very nice clean condition maybe 5 runs On it All original kit truck
Do you have the files anywhere fur is to download?
could i possibly use mig welding? since that's all we have and don't have the cash to run out and buy a tig welder. i run on 0.35 wire with mixed gases. im looking in making custom bumpers and roll cages, but don't like what the markets have to offer. Thank you very much and cant wait to hear from you soon, keep up the great work!!
You can use a mig welder, but it will be more clean up work in the end. A lot of people use a MIG though, so by all means you can still jump right in.
Harley Designs What kind of material are you using for the chassis? Would Carbon Steele be a good material to use for a Trophy truck?
Crawltheworld You sure can. Use any wire feed welder. A good tip is to mask off the area your not welding to avoid flux spatter on the rest of it.0.26 or 0.30 mild carbon wire in a 90-125 amp wire feed welder would be great for this little stuff. And on shielding?.......Read this;I wrap a bit of small dish sponge around near my work area that's slightly damp. Holding it with a wooden clothespin. It leaves no adhesive residue for additional welds on the steel.
icebox829 Mild carbon steel rod. About $1.75 per foot at the supply store. Sold in four foot lengths.
You can make pretty much anything with either method.
Give more details for scaling scx10 chassi
where do you buy you 3/16 tubing?
Is using 3/16" or 1/4" brake line instead of steel rod a good idea?
+juancarlosruiz1985 it works very well, but you'll have to braze it.
How would you lay all this out without CAD?
is it possible to use 3/16 with your temate please respond.only because I'm going to build it in my welding class
Yes, 3/16" is just fine.
I have a question, I braze with a simple oxygen torch, acid flux, and silver solder. I was wondering if you had ever had any problems with the solder dripping or just not creating a joint. It just kind of melts on there and either drips off or just creates a blob of solder that connects nothing. I was also wondering, can you print the templates on regular sheets of paper or do you have to have a bigger printer?
If the joints are clean and flux'd then I usually have good luck. Some of my prints are designed for regular size paper, but not all.
+Harley Designs Thank you! I'll have to try cleaning them up a little better before I braze.
Graeme Davis u need to heat the metal more and let the solder melt by touching the metal not the flame. cause sttel has a much higher temp b4 it melts then silver solder
bonito prooyecto
Will the scout templates work on the scx10 2 ?
Yes it will work well with that rig as well.
Do you have a template that is available for download I'm trying to make a cage for my 1/8 scale buggy if you could help i would appreciate it thanks
R50's SS You can go to my website and see what templates are available for download. I don't work with 8th scal buggies as they aren't really used in the scale market much.So you will have to use one I have as a base and go from there. The Ibex Goat would likely be the best start for a truck that size.
This video is pretty old, but do you use the same bender for tubing? If you do does it flatten the bend? Any info on this for a guy getting into scale fab would be awesome! Thanks in advance
For tubing I use a bender from Oakenshield Productions. The rod bender I showed in this video would flatten the tube just like you thought.
@@HarleyDesignsInc if you’ve got the time, a video on that would be sweet! Just ordered one off fb. Thankyou for the reply! Love your scale fab work!
@@Haymaker_Jake I don’t think I’ve got a specific video on it, I’ve used it in many videos but I can’t think of where to point you exactly for it!
@@HarleyDesignsInc I’ll have to see if I can find it!
@Harley Designs (or anyone else) Can you send me a link to the jewelers touch and bottles? Been in the RC hobby for awhile, and now i'm wanting to build my own chassis. I only have a small amount of "Play Money" set aside and don't want to blindly start ordering everything just to find out i ordered the wrong things.
+The Choosen One (Liquor by the Ounce) I actually don't see if listed on harbor freight any more. That's where I got mine.
I was thinking. For a beginner that's wanting to get started on a budget, JB-Weld should work, no? I've used JB-Weld for guick repairs on my cars; in-fact i repaired an exhaust hanger on my truck back in 2009(?) and it's still holding strong. I've used JB weld for repairs on my RC crawler and i've bashed the crap out of it and it's still holding strong.
The only problem i can think of is getting the pieces to stay in place while the jb-weld cures, and it would take longer to complete a build. But i just don't see a problem with the strength being an issue.
+The Choosen One (Liquor by the Ounce) for the size and forces we are looking at, I do not see it working. Not unless you used very large amounts and the visual of that would be very unappealing.
hey i am new to this and want to know what metal did you use for the whole build
+Derick Bills i use standard steel rod, either 3/16" or 1/8" diameter.
can you actually build an entire rc truck or anything like a car out of aluminum or steal.I know i would have to buy the other components
+Derick Bills not sure what you're saying; but what I show in this video is building a vehicle out of steel. I have several videos showing the completion of these trucks.
i need to find them start to finish lol
What video series is the one where you built the complete truck.
I working on a roll cage myself is there a way to put it together with out welding ?
Using a torch and silver solder is the best option and fairly cheap.
Thanks
Do you make this chassis and sell it?
What is stronger though
Build one for the Scx24!!!!! ❤
@HarleyDesign whats your welder amperage, & argon flow?
Depends on the material size and type. It ranges from 25-60amps. My argon is usually around 15.
@@HarleyDesignsInc awsome thanks for the info man! I was going to try to make some sliders out of 3/16" steel rod, first. Then go from there.
