Loved this video series, you make welding look so easy. I have tried it several times and it is hard as hell. Great job, you have got some serious skills.
@chryco63 The pipes I think you're asking about will be trimmed back and gusseted. There are two reasons I don't fish mouth and fit the center door bar - The bar is farther away from the drivers elbow and the bar can not break free and enter the cockpit when uncut.
@shodanxx The clearance is more than the production car interior, because the bars are curved into the door. Aluminum racing seats will not deform. One of the worst thing you can have in a race car is the driver staying in one place and having bars move into them. The goal of this will to have the entire cage move under her and she moves with it. There will be roll bar padding, which look like water pipe insulation, but made of a foam that rebounds when struck(unlike water pipe foam).
Getting my learn on! Love the hi speed vid and voice over format. Me and my son and his Njit engineer buds are getting ready to do a cage. Lotta welding practice goin
At first I was "meh," then I was "huh," then I was "whoa." That is going to a very seriously strong roll cage. Thanks for giving us the bar type at the end, I was going to ask because I couldn't remember if you said it in the first video (with the bumper/front bar).
your building a really rugged car. alot of chassis builders now build flimsy lightweight crap.. and the first time you get hit the chassis is all bent to hell.. love the vids
(with slack country twang) You got purdy welds on that race car girl! I'll defer to your experience but about the offset vertical tubing, I've been under the impression that alignment on on that kind of thing would be better. In home construction it's "stack framing" you can get the same structural integrity with less material. Race cars aren't houses but I would think some of the same principals could. Regardless of my opinion it looks good and strong.
@neuraxon77 I've seen that design before, but I'm not a fan of the longitudinal strength, because the bars are too vertical (great for front to back strength). This class of car is 3500lbs minimum weight, so side impact is of great concern. Keep watching the videos we have a lot of stiffening members to install.
The tubing bender that you are using is unique. Can you tell us about it ? Is it a home brew design, or was it purchased ? Thanks....and my compliments to you for the excellent and unique science and engineering video's that you have created.
Nice job,I like the way you impravise. I'm restoring a 1991 ws6 Formula Firebird. I bought it out from under a tree, I have a 71 Olds Cutlass I did a frame off resto on. But this is my first time for a unibody . Dude said car sat for 3 year's, turns out 10years, Rusty Rusty . but I weld and fab so I like a challenge,Any suggestions on subframing a daily driver
Very nice work.. What type of metal is the roll bars? Mild steel or Chromoly? They look to be mild steel. Also if that is the case are you using 25%, 75% argon? Thanks..
@zerosomething If I didn't have to deal with metallurgy I could stack the pipes, but without an annealing step it's better to offset them. My mentors drove that into my head from day one. It's ok to weaken a pipe by heating all sides of it if it's not near the driver.
how much clearance will there be between the driver seat and the roll bar ? properly designed seats are designed to deform when the car is rear ended reducing the impact felt by the driver, if there is not enough room this effect is cancelled (of course many(most?) race seat are WAY too strong and don't have this effect), also we put some of those pool foam noodles in strategic places of the car (especially left side of the driver) they have been shown to be very effective at reducing injuries
@jeriellsworth Makes sense, thanks. Could you possibly take some detailed pictures of what's been done so far and post them on your blog or something? I can understand speeding up the video for the fabrication process, but I'd also like to see the work in detail, simply for reference. Also, any chance that you'd consider compiling this series onto a DVD for sale when you're finished?
@jeriellsworth sorry, I was not clear, I did not mean in the case of broadside collision in fact I really like how left hand bars are curved away from the driver, ours are straight because the door still have to work, your design is safer in that way I meant in a rear end collision, some OEM seats have a bracket that will deform to a point (until they hit a stop) absorbing some of the energy in our car the bucket seat are right up against the roll bar that's the unsafe part
Are the ends of those bars just butted up to the door jamb? Do you reinforce that area at all? And how come you've stitched together those bars instead of cutting and splicing them into that upright? Just curious. Our cage was a kit, and I'm just enjoying seeing one hand-built. Looking forward to the next videos in the series, Jeri!
@jeriellsworth AHH that makes sense. It would defeat any extra stability you might get from stacking and create weak points. I should know about annealing, was a silversmith in a former life. I failed to think about that in this context and you probably said something about it in the video that I didn't pay attention to.
@papalevies This was my first career. I've built dozens of these type of cars and dozens of full tube chassis. Doesn't it look like I know what I'm doing?
I have never seen a tube bender like that- so compact. Do you like it? Do you find it flexible in capability? Also- what make/model TIG are you using in the video?
LOL Asked the question 3:00 in and @ 3:09 you state your using mild steel.. haha . you using 25/75 on the gas or what? 25/75 is what we use with mild steel just curious..
Jeri do you have any experience with this stuff? I understand your friend will actually race in this car so it might get dangerous if you don't know what you are doing.
Racing cars and computers. Wow, im stunned. Jeri, you make up for all those boring girls interested in nothing but fashion and makeup. I dont want to be nitpicking, but please be careful about your hair. ;)
Some people measure tolerances in mm, others in ", you appear to measure in months. Guys /gals... Anyone... Symmetry Oh and, think how you might get the driver out of the car if he / she is unconscious. You're not building a bath tub!
Your work is much better then most guys on youtube!!!!! Nice work!
I really enjoy watching quality work and people that genuinely care about the quality of their finished product. That seems to be becoming more rare.
Loved this video series, you make welding look so easy. I have tried it several times and it is hard as hell. Great job, you have got some serious skills.
"I cut it twice, but its still too short" is one that I have never heard lol. Thanks for that.
Multitalented, you are. Nice welds, too (coming from a welder).
Coming right along Jeri. Looking Great. Hope Trish is soaking up all of this Training!
Nice to see girls getting into racing 100%, you are doing a wonderful job can't wait till its up n running.Will be following!😃

can't wait to see the next one of these videos, I think this is my favorite project of yours so far!
this is great stuff.
you might want to consider making a DVD (videos+plans and details)
it would surely sell well.

Those welds look sweet. Nice job!
Wow nice soldering, i remember my first car was a 81 camaro Z28 350ci quadrajet carburetor with a 350 trans a beast of car.
engineering knowledge meets fabrication experience all in one
This is so cool Jeri. You should have applied to go on Scrapheap Challenge or Junkyard Wars. You would have kicked ass at it! :)
Nice clean welds! Gotta love that!!
Nice work Jeri and thanks for posting these videos
Sweet! Jeri you're awsome!! Ive been subbed to you for about a year! and always interesting stuff on your channel!
Thats an interesting way to build door bars, ive never seen it done that way. i like it =D
your building a really rugged car. alot of chassis builders now build flimsy lightweight crap.. and the first time you get hit the chassis is all bent to hell.. love the vids
@JAQUEOBAUER It for sale online. It's called the "Affordable" bender. It works pretty good when you learn to lock it with a clamp.
That's some hardcore speed welding right there :p
highspeed welding is really sexy... haha
i love these kinds of videos you made lately! makes everything seem so easy :-)
(with slack country twang) You got purdy welds on that race car girl!

You do nice work. I'm impressed.
Jeri - you work so fast :)
@awesomizer I use 75/25 and the wire is mild steel.

Jeri you do awesome work I drive a hobby stock/enduro car in Md and Va
me thinks circuit girl knows a lot more than circuits.
looking great.
your welds are beautiful
The tubing bender that you are using is unique. Can you tell us about it ? Is it a home brew design, or was it purchased ?
Thanks....and my compliments to you for the excellent and unique science and engineering video's that you have created.
man oh man this girl knows her shit !
Why not?
you are simply made of awesome!!!
You ladies are awesome.
Nice job,I like the way you impravise. I'm restoring a 1991 ws6 Formula Firebird. I bought it out from under a tree, I have a 71 Olds Cutlass I did a frame off resto on.

you are a great welder
thats a strong door and your awesome.
@neuraxon77 The triangles are on the way. The door is not the place for them.(maybe in a drag car)
Very nice work.. What type of metal is the roll bars? Mild steel or Chromoly? They look to be mild steel. Also if that is the case are you using 25%, 75% argon? Thanks..

@SuperFinGuy She's the other half of the pinball route business.
Jeri , You are really good. :)

I like your welds
Really awesome. Do you have a 'notch' fixture? With a tubing bender, I would assume you have a tube notcher.
@jeriellsworth
sorry, I was not clear, I did not mean in the case of broadside collision

wow
You girl rule!
I don't do anything with my life and watching your videos make me think...
Are the ends of those bars just butted up to the door jamb? Do you reinforce that area at all? And how come you've stitched together those bars instead of cutting and splicing them into that upright? Just curious. Our cage was a kit, and I'm just enjoying seeing one hand-built. Looking forward to the next videos in the series, Jeri!
Damn Jerie you are the coolest girl I know online!
nice to see a mistake genuine video thanks for showing uk
@junior17817 This car will be racing against 3500lbs cars on dirt, so it has to be very rugged.
@jeriellsworth AHH that makes sense. It would defeat any extra stability you might get from stacking and create weak points. I should know about annealing, was a silversmith in a former life. I failed to think about that in this context and you probably said something about it in the video that I didn't pay attention to.
good job, looks nice
Do you have any details about your tube bender? Looks like a different design to most I've seen before.
@shodanxx I see. Every class of car has it's requirements. Trish gets to play Dukes of Hazard with her nonfunctional doors. :)
great job
three words. removable steering wheel. its what i have in my car
@papalevies This was my first career. I've built dozens of these type of cars and dozens of full tube chassis. Doesn't it look like I know what I'm doing?
@MrSeayLego Grab the halo bar and slide in the window.
I have never seen a tube bender like that- so compact. Do you like it? Do you find it flexible in capability?
Also- what make/model TIG are you using in the video?
@snower5554 It's similar to Rayburn chassis.
I wish I was as awesome as you are.
Impressive!!!.
Damn i love cars... :)
Is it that easy to weld or are you damned good and are those short vertical bars called "cripplers"?
@Zimkader go to your local track and find some guys you can help
LOL Asked the question 3:00 in and @ 3:09 you state your using mild steel.. haha . you using 25/75 on the gas or what? 25/75 is what we use with mild steel just curious..
@misha6119 Of course!
hii jeri,
please you upload saw filter test with oscilloscope.and same vedio of evrey resonator..
this typ not any video on youtube.
Nice world
Jeri do you have any experience with this stuff? I understand your friend will actually race in this car so it might get dangerous if you don't know what you are doing.
what steel pipe are you using.
Man is my comment to an old thread
Girl can weld :)
@HEYITSTHATBLACKGUY They use a removable steering wheel.....
how many pounds of wire did you use?
how do you into the car
this videos fkn hot man.....
Lovely welding ! But I got a flash watching it without a mask ! I can see a lawsuit in this ! should have had a warning on this video !
Steve Swan I hope you are joking
Moar!!!
wouldnt it just be easier and cheaper to go just buy a roll cage kit?
who is gonna be racing this
cars, circuit engineering, ata girl, ?Whats the next hurdle woodworking.
Racing cars and computers. Wow, im stunned. Jeri, you make up for all those boring girls interested in nothing but fashion and makeup.
I dont want to be nitpicking, but please be careful about your hair. ;)
kinda weird roller bars
will you marry me?
i wish she want my girlfriend ....
Get in the kitchen and cook my food woman
OMG.. worst I've ever seen!
Some people measure tolerances in mm, others in ", you appear to measure in months.
Guys /gals... Anyone... Symmetry
Oh and, think how you might get the driver out of the car if he / she is unconscious. You're not building a bath tub!
