Calling K5TPI or anyone else with a cage in their K5......

[barbastard]

How much tubing did you use to build your cage? Also, what type, diameter and thickness?

It’s time to build mine and Santa was kind enough to deliver the funds required for it so it’s go time!!! I’m thinking 1 ¾” diameter, DOM seamless, .120 wall. An off the hip guess at the amount required was 60’. Going to do a 6 point cage with integrated seat mounts. Got a buddy of mine that has a bender and is a pipe fitter/welder by trade so he’s going to help me out with it (or should I say….he’s going to build it for me and I’m going to help out as much as I can, try and learn some stuff and fetch beer).

I did the help someone build mine trick years ago.
We use 1 3/4" DOM tubing .120wall but I can't recall how many feet we used :unsure: oh and it is a 6pt w/o seat mounts.

[KidJethro]

My cage has alittle more tube in it than you'll need, but I can still give my input. I used 220' of 1.75 .120 wall 1025 DOM. At the time it was $3.07/ft. Alittle over $700 total I think. Got it trom Team Tube in West Sac. When I was figuring how much tube I thought I was gonna need, I figured 180' and I'd have a stick or two left over...Ended up with one 6' section and bunch of smaller pieces (under a foot) left over. If your initial guess is 60', order 80'. :blink:

Just make sure he has a tubing bender and not a pipe bender. They are measured differently and one will not work for the other.

[k5LS2]

I think I used 45ft of 2" 120 hrew (hot roll) I need about 20ft more :crazy: I feel the cost of DOM or Cromoly is not needed in our sport, save yourself some coin :2thumbs: If you were blitzing across the desert at 75+ then I would use the higher grade tube. If you need some help PM me :thumb:

[jays68yak]

about 10ft with some small lengths left over.

He's got a bender with a bunch of pipe dies, but he just ordered one for the 1.75" tube yesterday....should be here in about 2-3 weeks. He's been bending tube/pipe and professionally welding for over 15 years so we should be ok. As far as the $$$ goes for the tube, I considered just building it out of schedule 40 pipe because he can get it for free and he's built a couple cages out of it (including one on his jeep) with absolutely no problems. But...I wanted the extra security of the DOM and figured if you're going to do it...do it right. Besides...I'm going to get a KILLER deal on the DOM anyways....I called one of my structural steel/miscellaneous metal subs yesterday and he's going to get me his price for the tubing so I should be saving a BUNDLE. I 'll post up when I find out how much he gets it for me.....for all I know...I might just be getting it for free. :D :pimp1:

I think I'll up the order to 80' just to be safe. Thanks for the input guys and no doubt I'll be posting up more questions about cage design etc. My hope is to have it installed by the presidents day run. Just depends on the weather cooperating and getting 1 or 2 weekends free.

Schedule 40 pipe is actually stronger but heavier, I don't think you want the extra weight up high if you can afford not to, but strength wise you are not getting more with the DOM tube.

WHAT????? How do you figure that??? :unsure:

The minimum tensile strength for Sched 40 pipe is 48,000psi and the minimum yield strength is 30,000 psi.

Compared to a minimum yield strength for DOM at 75,000 psi and a minimum tensile strength of 85,000psi.

How do those numbers support that sched 40 is stronger than DOM? I can tell you in the 3 big steel jobs I've done (one was over 2600 tons and the other two were both about 300tons) I've NEVER seen a piece of sched 40 pipe used in a structural application. Other than as seismic braces for the fire sprinkler system.

Regardless...I'm going with the DOM. Spoke with my steel sub yesterday....he's getting me a good price on the 80' of tubing I need......FREE :beer: :D !!!!! He told me to call him when I need it and he'd deliver it to me the next day. Gotta love that!!!!!

[Ryan B.]

Yo nate...

Can you hit up the guy and tell him that a couple of good friends in your 4x4 club need some 2" .120 wall DOM..
Probably 200' or more! Best i've found is like $5.00 per foot.
It would also need to be delivered to kevins place in Morgan Hill, CA.

I'll talk to him about future deals and what kind of prices he could get us. I'm positive he could beat the $5/ft. I'll talk to him next week and see what I can do. I don't want to "wear out my welcome" so to speak...so I've got to play it cool :pimp2:

[seschev3]

My buddy has the 1.75" dies, depending on your buddies bender, that can probably be borrowed. Let me know and I will check. I will be starting my exo cage here in a couple of months, so the die will be freed up for a little while.

[barbastard]

Thanks for the offer but my buddy has already ordered up the 1.75” die. Not sure what kind of bender he has anyways. I’ve got to give him a call this week and see when the die is due in and start going over the cage design.

[PaloAltoK5]

Mmm...cage....

http://silverlegend.biz/wheelin/Blazer-3.jpg

[barbastard]

Well…the dies have come in. So…going to design the cage over the next couple of weeks and get to installing it after the run on the 19th of February. Talked with my buddy…he now wants to TIG the cage…says he’s got all the stuff for it and he prefers to tig anyways. I was like…”um ok….twist my arm :roll: !!!”. So, so far this is turning out to be a sweet deal…free tubing, more or less free labor, TIG welded….I like where this is going. :D

I’m going to start drawing up designs this weekend. I’ll probably have questions for you people with cages already.

More to follow……

i was talking to the driver of my steel suplyer he said dom 1 1/2 120 wall would be about 2 bucks a foot delivered to my shop

I haven't run the numbers myself (though I could in ExcelCAD!) but the wall thickness can make up for the "lower" numbers in tensile strength and yield. Larger diameter tube will be stronger than the same wall thickness in a smaller diamter also..... Check the "materials" tab in ExcelCAD.

You can type in the tensile strength properties, and then play around with the wall thickness and diameters and see how it affects the various "Factors of Safety"....

[barbastard]

Working on the final pieces of the design for my cage and I’ve got a couple questions for you guys:

1.How have you guys tied the cage into the frame?
2.Did you gusset the corners where different pieces of the tubing met?
3.Did you make all the pieces continuous or where there any purposely made bolted connections?

Hopefully some of you guys can offer some good answers here. I should have my tube in on the 15th and if the weather is good this weekend, we’re going to try and knock this thing out in two days. I’ll take plenty of pictures….

1. I have not tied into the frame but would probaly use bushings from ORD. Also sanwich plates from Kert at DIY are perfect for that with the top and bottom plate that also has a anti-sheer pin. I used them when I built my cage.
2. I used gussets from DIY at the main 90* corners, but could also just triangulate some tube.
3. I made a 2 piece cage that allowed me to remove the cage. To get the front of the cage in I had to angle it back to clear the winsheild pillars, which I could not do with the rear attached. Plus I made my cage to allow for the soft top tp clear when folding down.
Hope this helps and if you need any help, let me know.

[barbastard]

I’m definitely going with those plates from Kert at DIY4x. But, I’m just having trouble figuring out the best way to attach it to the frame. After speaking with a couple people I’m pretty convinced that I’ll tie it into the frame by using a bushing assembly welded onto an outrigger going from the underside of the plate at the body to a welded plate onto the frame. It’s going to be a pain in the ass but should be pretty strong when done. The difficult thing about all of this will be locating the downtubes so that I’ll have clear access to the frame from the underside of the plates.

I’ll probably order up some gussets as well to reinforce some of the corners. The way I’ve got the halo designed it’s already pretty triangulated. Before I build the whole thing I’m going to have one of my structural engineer’s I work with take a quick glance at my design to make sure I haven’t completely fucked it up. Unfortunately, it’s been about 7-8 years since I was in any of my engineering classes and I’ve forgotten a lot.

Where did you point the “joint” in your cage to separate the two pieces? How did you connect them? Did you use these (http://www.diy4x.com/images/stakedflange2small.JPG) or these (http://www.diy4x.com/images/360%20tube%20tab.jpg)? If possible, do you think I could come by sometime in the next couple days to check your cage out? You live over by Greg (I think that’s his name) in Concord, right? I bought some stock tail light lenses off of ebay a while ago from him. Thanks for the help.

Yeah I used http://www.diy4x.com/images/stakedflange2small.JPG above my wheel wells.You can stop by after 5:30-6pm most nights or the weekend. Just call me @ 925 381-0335.
