Crawler Tube Chassis - In Depth How-to 

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!

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

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

For regular carbon steel I just used the standard filler rod from the welding supply shop, 1/16".

This is sooo cool. Really impressive, and it looks like so much fun.

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.

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.

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

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.

thank you, I learned something new today, and loved it, very cool, smash that like people!!!

Yes the templates will be uploaded soon.

Very nice video and well explained. Inspirational as always!

cool vid love the one's you have made!! have to make a rock bouncer for my next protect

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

great how too video hope to see more on this build big thumbs up

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! Carmine 🚂

There's a lot of really useful info here. Thanks!

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.

hey harley, ur design r very awesome but i m stuck with the circuits for servomotors and rc control.. can u share d details...

Think you could do a video on your process on putting together the chassis together?

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 video...got my ideas flowing!! thanks

This is awesome!! ‘And things like that’

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.

nice vid man !!! have a question were do you get those tubing? whats size is thats tubing

thats a cool piece of work

Hey dud ..nice ..!! Since im an aerospace welder i will take advange of of it ..i wil make it out of titanium tubing

Awesome video, your bloody brilliant with rc's

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.

Love it great video and great technique on all of the different methods🦾🦾🦾🦾🦾🦾🙌🙌🙌🙌

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

good and informative video:) good work, and please put the templets of this on your web site?

I want one of your steel setup plates (the plate with all the holes)

DUDE THIS IS AMAZING!!!! Thank you so much!!

How much would charge me to build a full cage for my 4runner body on a scx10ii frame with my full interior?

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?

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.

Very nice job thanks for this video....

Where do you get your tubing?I am thinking of getting into building chassis for all of my 7 rigs.

Are you using solid wire rather than tubing such as brake line?

Thank you for putting up this vid. Very informative. :)

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

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.

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

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?

Thanks for sharing this!

Resurrecting this one from the dead....

I have an old Stick welder, could i use that or shud i upgrade?

Thanks man. That was great Info!

Would you try MIG with a cage?

link to the buildlog for the original truck?

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.

Do you have the files anywhere fur is to download?

What material can be used for cars Less weight and good strength Budget price

where do you buy you 3/16 tubing?

What CAD program do you use?

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 website did you use for the lines

could i make a rock bouncer with the cheap metod?

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.

Thanks, but what filler rod do you use?

What company make that bumper mount

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...

harley, what program did YOU use for this video?

Awesome video! Very informative. How heavy is one of those roll cages?

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.

You don't always need to use filler rod for tig welding.

I've never used chromoly tubing so I can't say what would be the best choice for that.

Thanks this will help!

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

Do you make this chassis and sell it?

Give more details for scaling scx10 chassi

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.

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?

How would you lay all this out without CAD?

What CAD program do you use

Is it hallow or is it solid

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

What is stronger though

bonito prooyecto

is it possible to use 3/16 with your temate please respond.only because I'm going to build it in my welding class

thanks!

Is using 3/16" or 1/4" brake line instead of steel rod a good idea?

I working on a roll cage myself is there a way to put it together with out welding ?

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?

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

Could this have made with brass tubing? Great video!

Like I mentioned in the video, most any CAD program would work. I am using a civil design software that would not be available to most people.

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!!

Will the scout templates work on the scx10 2 ?

You can make pretty much anything with either method.

@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.

@HarleyDesign whats your welder amperage, & argon flow?

What app design

Have you figured out what works best for building a Jig?

Could u braze with a propane torch??
