I really like this style of roll cage, I like the low profile and the sporty look. Are they available to purchase pre-fabricated? If not can anyone refer me to some plans so I can fabricate them myself?

Also, what size windshield fits in these roll cages? And how would I mount the windshield inside the cage without it's own window frame?

Thanks!

Your 2nd picture actually has an aluminum windshield frame with a roll hoop behind it.

The other 2 have used a special mounting gasket that is something I too am hunting. I'm sure one of the brighter members will come to our rescue shortly....

I stand to be corrected but I believe most cages of this type are custom fabricated, either by the owner or a shop. I am not aware of any kits as there are too many variables.

Here is mine. Pardon the mess which is my buggy right now. I'm getting it ready for paint.
I did mine myself. (I have the tools.) If you notice, the very back tubes go thru the body and bolt to the engine cage. I figure it will all help to support each other. The grommets are intake manifold grommets cut down. Worked great!!
Check out my other pix if you like.
Hope this helps in some way.

Is this what you need to mount the windshield?

It's a Bugpack item so you might have to hunt for it.

Opps....sorry. I was going to post that as well. I was in a hurry and forgot. But that is what I used. They are for rails but, they fit nice against the dash too. You just have to cut it for the two dash corners. I black urethaned mine in. It's what they use for windshields. Good stuff. I was initially thinking of using a couple s.s.screws or pop rivets to help but, no need in mine. I got the glass cut to fit tight.
Good luck!

Power,
The pictures of the buggies you have posted were all made using Dave Barrett's www.manxchassis.com chassis and cages.
The cage is a integral part of the chassis.

Contact Dave, and see if he can help you out.

I was actually gonna purchase Dave's rolling tube chassis, but I didn't see that roll cage design as an option on this site, so I wasn't sure if he fabricated those as well. In terms of safely, stability, and technical know how, I don't feel confident to chop and shorten a pan, Dave Barrett explains the negatives of using a chopped pan pretty well on his site and promotion video.

As for fabricating a cage that bolts to the chassis through grommets in the body, that looks fairly tricky and difficult to get all the tubing to line up accurately. Dave has jigs and fixtures that insures all his chassis are square, straight, true, strong and safe. I might just save myself a lot of pain and frustration and just purchase one of his chassis.

If you're talking about his perimeter type chassis(below) which I believe he calls a "full tube", each one is custom built. You'll need to bring your buggy body to him, he constucts the chassis to fit around the specific body.

This is fairly straight forward. I did this type of a thing years ago in a rail. Sorry no pics though. Going off an ol man's memory. I think I used 1×1 or 3/4×3/4 angle aluminum. Thin gauge. All you have to do is make multiple relief cuts at the radius. I kept the flat bottom piece seperate. Some of us, screwed the frame in some pop riveted. Any glass shop can make template and install in about an hr. No ureathane on ours,it was a "H" type of rubber gasket. We could remove windshield easily for paint, welding or repairs. The windshield frame wasn't visible from the front just backside. The gasket came all the way out to the frame tubes.

Building my own tubing bender and purchasing dies. There are options for 90 deg and 180 deg. Not having experience with this, will I need anything greater than 90 deg for roll cage and bumpers?

I've been trolling the threads and can't seem to find any builds with more than 90 deg bends.

Be very careful when buying or building any kind of roll cage. Most of them are not designed with enough strength and integrity to protect your life in a serious street accident. Many are just fancy looking show bars and not life saving roll cages. It does not matter how light your Buggy is when building a roll cage. What you have to realize is the weight of that 5000 Lb. SUV that is crashing into your 1300 Lb. Buggy. There is a huge difference between rolling a Buggy in the sand dunes and crashing a Buggy into a concrete object. Just because something really looks cool DOES NOT mean it is built correctly with good engineering principals. I suggest reading a NHRA or other racing sanctioning body rulebooks for guidance.

I have 90 degree dies, I would rather have 180's. it's up to you and how&what you want to build. also some 90 dies can bend 180 if you rotate them and some cant....currently as mine are made that cant I will remedy that flaw. have a look at a rail buggy and see somany more than 90 degrees.

90 degree dies are all you really need unless you are going to do some trick stuff. I did all my cage with a 90 but did buy a 180 die for my 1" Dia tube. I used it for a little tube bumper in the front.

Check out my build in my signature if you want some ideas how to pass through fiberglass with out drilling big holes (And making it removable) it's one of many ways of doing it. My car does not creek, its ROCK solid. I am very happy with the results (10 point integral cage design tied in through out the entire car).

Cage material is as important as the design. I used 1.625 Dia .120 wall DOM seamless tubing. NHRA spec tube.

I was going to have someone build my cage, I soon realized it was going to be very close to the same price if I bought the bender, notcher and I bought bending software (I already had a mig welder). Now I have the equipment and have done a few other cars since.

Go with 180* dies. If you're building a bender, build the best bender you can so the tool doesn't limit what you build.
