Seems like adding a short tube, elbow to crotch, would make a big difference in that example. The bend with no support is sketchy. Wait, the more I look at that, the more it bugs me. The bend is bad. It would be better to make the side tube straight and connect it lower to the rollbar than bend it like that. Ugh, we are venturing outside best design standards. Bends are for hoops. Tubes between pillars should be straight and triangulate. Hey I'm a poet and don't know it.

Here's what Tony did on my cage. Ignore the temp bracing ...

How about this brace?

Bingo.

if I wasn't in massive debt from the new house...
That is a great looking piece Mark.

Can't you add a new cage to your home loan?

Material for three cages ordered today for delivery next week!

Note the back-up for the door bars. I see some with (Andy's, for instance) & some without.

I'd order one, but I think I am going to wait for AA to offer it for $5 cheaper in a "What's New" thread

Should expect to see one real soon...........

Could this work to replace my "missing" targa bar ?

It would be better than nothing.

Wow that looks fantastic. I have been putting off doing any work on my car but this with some interior upgrades would look so sweet.

How is this project progressing???

I asked Dennis at Assco Racing about the same thing years ago and he mention the same thing- "side tube straight and connect it lower to the rollbar than bend it"


Also when I mentioned OK..But can you build me one anyway? His response was NO – it’s too much liability… in a racing environment

For the street- a great looking product- good luck with your project!

Hi Mark
How is the half cage going.

Bruce

Certainly not a Hijack, but if someone buys a McMark Bar and wants the forward pieces, I have them from a Safety Devices Cage that I just used the rear bar

I'd like to know too. I talked to Mark a few weeks ago about one but nothing came of it.

I'm still interested!

Thanks,

Peter

Well I gave mark the money in November for one, I have PM him twice and not heard back.

Bruce

emailed Mark asking if I could stop in to introduce myself (I am local).... he responded quickly.

He's around.... busy, I'm sure.

Cheers!

Hi Mark whats the story on the half cage.
Bruce

Sent a PM. Not sure what happened to the other PMs I sent... Certainly not hiding from ya!

I would still love to trade for one

Mark.....any update on the GT half cage? I'm looking to install something this winter...

Hi Mark I have 2 weeks off a xmas I was wondering if I could come up and pick up the half cage then. Please let me know

Bruce

Yup, getting them all built this month now that I'm finally getting caught up on all the cars.

Mark,


When you get them going, I am very interested in one.

Thanks,
Vysoc

Hi Mark I was wondering if I can come up and pick up my Half Cage on December 28 or the 29 please let me know.
Thanks Bruce

Any updates?

Actually, Mark was building half-cages today...

I saw pitchers ...

Did it look like this?


(stolen from the Original Customs Facebook page)

Maybe ...

Cool! Thanks for posting pix!

Hold on now! I'm not sayin' that's Mark, or that that is a GT half-cage being made. I'm just sayin' it looks like Mark and it looks like a GT half-cage. Ya'll draw your own conclusions

Mark's a little busy trying to have a life outside of Original Customs and 914World right now... He might have more time if my 240Z would sit, lay down, and roll over when he commanded it...

I think that damn Japanese car has contaminated his shop.

He thinks it's a curse... He has two in the shop and neither will run right!

Damn, I wish I had seen this thread when the pre-orders were being taken. I really, really, want one of these.

Contact Mark... Very reasonable guy. He will probably hook you up. Just tell him I said building you a half-cage would probably be easier than tuning my 240Z!

UPS stopped by!

SWEET!!!!

Looks like they tried to lose one of the down-bars. Glad it stayed with the rest. Guess I'll have to do a better job on packaging.

Between the plastic wrap and the ties, it stayed, but it came out pretty easy when I broke the tie wrap and wiggled the piece a little.

It looks great!

These look fantastic mark!

Mark,

Do you have any pics of your hoop installed in customers cars yet?

Looks rad.

Looks really great! Has anyone confirmed if this design would meet SCCA or NASA roll bar requirements for Time Trials or Hillclimbs?

Another thought on improving rigidity, is to add another forward bar that runs along the longitudinal. The trick, I've been told is, tightly clamp the bar to the long, then weld it into place along with the cage.

Don't know if it'd make a difference or not, but thought I'd mention it.

-Josh2

can't wait to see instal pics

doesn't look like it meets any current SCCA regs.

Tony does great work.

If you're street driving you're more likely to get bonked on the top bar (back hoop to front hoop) than the front.

My original cage was like yours and there was nothing, in the form of restraints, to keep my head from hitting that back to front top bar. The big racing belts I use would keep your head from going forward and hitting the front hoop, but guessing most don't use the shoulder harnesses on the street as they aren't very comfortable if cinched tight. Most just use the lap belts.

I like the cage I have now in that there is nothing high in the front (you can see) and the side bar is pretty hard to hit even if you try. Of course you might not want to cut your windshield off.

Are you still making these? After taking another look at Erics car I am considering pulling my 3 point bar and going with something like this instead.
