That’s the chassis tag. Just because you have a tag doesn’t mean you automatically pass track tech. Nor that the car is safe

This is a darn good reminder , for me at least, I need to thoroughly inspect mine again.

My car cracked bad at both bottom rails just behind the rack and pinion....

My good friend Frank Mark sent me pictures and called me to explain how to fix it exactly how the original car builder would and told him how to do that repair.

I found the cracks on Friday morning and by Saturday afternoon after getting some tubing, a tig welder and a few hours work it was fixed and is stronger than it was IMHO.

Hardest part was cleaning out the inside where the tripod arms are attached....

I used a die grinder with paper rolls...

I also left a little gap the width of the saw blade cut to weld better the outer tube and the inner sleeve.

I've looked at it numerous times after racing it to make sure it was ok and it is...

If I knew how to post pictures I would...but its just like the above post and picture

Left 35 thou for the fillet. Now the repair is stronger than new. Will never break there. Basically double wall moly in the most stressed area of the car. Just love those HT's lol.




The chassis repair was not bad at all. What was the pi** was the body panels all bent up along with the body tabs. I just painted the car 2 months earlier.Spent more time on body work X3 that the lower rails.



Nice and no need for any clamshell outer patch...

Or let's look at it this way: If the car in the other lane was you, or your wife, or son or daughter.....are you still 100% ok with the repair done to the car in the other lane?

Now if the repair was clamshell'ed or had a tube inserted, we wouldn't be having the conversation IMO. Was it?



Bucky, go back and read his second paragraph. The chassis broke near a slip and the inner tube was already there. If you watch the video Britt Cumming filmed on Facebook live, you will see when each side goes back in place.

If this is a common area for a tube break, why don’t they initially build this area with the repair that is shown above ?

Can't really see anything but a22holes and elbows working in that video. So you are saying they drilled holes and rosette welded that slip into the repair? I didn't see a drill involved. From what I can see, they slipped the tubes back into place, and welded the break. My question was, is this what a good chassis shop would do if you brought it to them? Not having 20 minutes to do the repair. Not big money rounds on the way. Would he slip it back into place and weld the break?

Safety is not situational. For critical repairs at work or on race cars, if a person or more than one person's life is at stake, the repair is what the repair ought to be. If a line costs us $75k a day to be down, and there is only one right way to fix it so that everyone is safe, the line stays down until the proper repair is made. Even temporary repairs are carefully scrutinized. I can't see much of what was actually done here. But to me it doesn't pass the smell test. I wouldn't put my only son in that car the way it appears to have been repaired. And I wouldn't want it in the lane next to him. Not due to feelings. But due to the nature of the break and the nature of the repair. Again, I can't see much in the video. So maybe there is more to it. Nobody is hating. Nobody is keeping the man down. The car broke and there was a valiant effort to repair it. My hat is off to the young man that wouldn't accept the repair, as I am sure there was, and still is a lot of scrutiny over his decision.

That is a good question.Due to flex and bounce, you would figure it should be a double wall making it safer. But then again light and no suspension.
Case in point, look at the fuel cars that have split in half right at the foot box. There have been a few.Back then i highly doubt annealing was a process on the builds.Basically stress relieves the area around the welds with annealing.

As we notice on these rock crushers (HT) they flex in the middle right at the driver area. You can see where it broke due to stress. Annealed. highly unlikely. If i was in the market for an update, i do another HT again.I won't have to worry about suspension, just tires and converter.Ya i might have to add some more memory foam in the seat for this old boy.All i have back there is a coupler about 6.5' long.

Well there was plenty of bounce at Bristol, right lane for sure.

The break was in an uncertified area of the car. NHRA chassis certification has nothing to do with that area. That area can be held together by nuts and bolts as it often is and still be a certified chassis

The cars at the race weren’t being teched in the first place....

Hats off to those guys 1000% trying to get it repaired.I feel the clincher were the ratchet straps that closed the deal. Just curious, how far away was the slip to the break?. This a single double or triple slip?

No matter. When the track became aware of it, liability follows.

^^^ Agreed.

I read the last section of the 2019 Fall Fling Flier and feel the written rules were followed.

IE: Final Call on all Rules and Decisions by Race Director(s).

Resisted posting on this one but lets look at some facts:

Car broke on a run bad 300 feet out! (it just didn't stop on a dime)
Little time to fix under less than ideal conditions.
Not all the parts available to fix the entire damage areas.
Not able to completely weld up the broken area.

Do you really need more reasons why they made the decision to not let him continue to race?

Sorry but all involved in this decision just could not assume the risks IF!!! This is really what it boils down too! Don't really matter what anyone else thinks about the repair's soundness to be able to continue to race!

Just imagine going to court with the above facts if the car boke again and a serious accident occurred. Judge, we added ratchet straps on it for JUST IN CASE REASONS.....

This car broke because of its design (not saying it was faulty either, just a high stress and movement area) and because it was not checked on a regular basis. It cracked long before it broke. Who's fault is it? HMMMM
