Today we show you how to fabricate a 25.3 certified Roll Cage in our 1959 Volvo PV544. Chromoly 4340, TIG Welding, fitment, Coping, you name it! T-shirts: www.paccracing.com/store
Best video to date. Well done. Knowing that this roll cage will soon be called upon to protect your father's life lends tremendous weight to your words. Little did you know you were saving his life for real! Twilight Zone time.
This has to be the best explanation of what goes into building a cage, let alone the footage, how to layout the plan for the cage, hopefully there is a part 2 coming soon
On the laying on the tunnel and other foreign objects; I have an old pop on creeper that used to have a bad wheel; without the wheels it made a great back board. Outside, in the mud, I have used thin plywood, cut to fit into whatever hole I needed to work in. I have always thought the roll bar was to keep all the "go faster from" killing you the first time you asked big and got more than you bargained for! FR
I spend most of my time in the off road racing rabbit hole. Mostly the same. One difference is that everybody uses 1 3/4” or 2” depending. Another you might find helpful is everybody uses Steel-It now. Its weld through paint. Very handy but a tad spendy.
You guys should get some plane nivlac57 stickers and stickers with nivlac57 and the blueprint of the motor to add to your site. Bought a shirt but imna suckered for stickers.
Great tips , but for me and tig welding. The painting can wait till the last procedure is done. Nothing like blowing a weld due to contaminate from the paint process. And being an engineer I figured you would have used Solid Works or BendTech for cage design. The balsa wood trick is a good idea for those without the program . 15 min mark is when I would paint. But that's me LOL. You guys are kicking butt!!! Looking forward to the end result and track testing!!
Yeah. I'm not a big CAD guy, unless you are talking about Cardboard Aided Design. Takes way too much time, and usually doesn't come out the way you want when you actually do it. If I had more precise machines, maybe... but probably not. Just not the way my brain works.
@@Calvin-Nelson I guess that depends on who's using the programs. I worked in two bending shop's. And they could hammer out drawings pretty quick. I have a old copy of Bend Tech. I bought it with my bender package. It paid for it's self the first car I did a cage in. But most of the time I lay out stuff. Especially single plain. A pillar bars, that follow the body lines tight. Bend Tech saved me throwing away materials. Great project. Looking forward to the rear suspension and frame updates.
@@hartiaacres yeah. I could see it helping with that. I just find CAD something that slows me down most of the time. Why draw the part, when I could just make the part. Just how I was raised, I guess.
@@Calvin-NelsonCalvin, not sure how many are aware that CAD designs are a tool limited by the actual dimensioning of mating components, unfortunately CAD being mixed with production tolerances doesn't work well in many cases as a practical consideration because of production variations which actually defeat the major purpose of CAD. I know from working with a few really sharp engineers that the CAD operators that produced drawings reflecting real world integration of CAD designs would call out for "as built" solutions to the issue of CAD precision mixing with mechanical "drafting variation in the pre-CAD era" components, they realize to make it all work sometimes it does take good old "trial and error" by the hands of an experienced tradesman to make it all happen.
@@Calvin-NelsonCalvin, thumb rheostats leave a bit to be desired, you may want to consider a simple on/off button and (possibly but not necessary) a remote rheostat, while it is not as slick as a nice pedal you can produce very high quality joints that will pass x-ray and visible inspection, in many ways this type of welding technique rewards those proficient in oxy/acetylene welding (no, not brazing) travel speed and the filler wire determine the actual joint heat.
Not sure if you are following sick week, but this cage did its job. The car went a 9.12 at 149 and went across the track, over the wall. Andrew did go the hospital but is doing well.
Yeah, at the risk of exposing myself as some lame old man I gotta' say the soundtrack sometimes is tough to sit through. Sometimes I really dig it(hell, I think you've thrown in some J.S.Bach at least once and some other non Car-Tube-Typical music) but I'm sure some other folks don't love THAT so I shouldn't get bent up. Again, not hating, I like your stuff alot
Maybe an after thought now but why did you not consider moving your seats back to make room for moving the firewall backwards to make room for the Ameribarra
Trying to retain chassis stiffness and reduce that effort. The stock floors are required for this level of certification as well. Not saying you couldn't weld them back in, it just adds complexity.
Looks like you were throwing rocks at the Mustang and Camaro crowd, i actually loved the K swapped Mustang and the 2J Camaro but i can hear the triggered purists blood pressure rising😂😂 Cage is looking awesome man, whats the info on that helmet you are using?
I was wondering when someone would notice. Lol. Thanks man. Here you go. Jackson Safety Rebel ADF Welding Mask, True Color Technology, Wrap Around Protection, ADF System, Flame Resistant, 46200 a.co/d/e8wg6r6
Like I said, they're not a one size fits all sort of thing. We made ours to take into account spring back. A 6 inch radius die does not always bend 6 inch radius. It probably is somewhat close though. I suppose I could sell the design we use.
Can you guys edit your intro music? It is so ridiculously loud I have to mute the TV every time it comes on. Other than that I love the videos just the intro music is way too loud
