You have to be brain dead to watch his channel though.

Very harsh on Mat, while it might not go into the technical detail of say M539, its a good balance of entertainment and a light touch on the technical side.

I think he was referring to Mr Beast.

My kids love him and can’t wait for a new video to drop. I must admit some of them are quite entertaining for 20 minutes before they go to bed. Isn’t he the most valuable YouTuber on the planet? Wonder what he brings in per video.

The guys from the machine shop are old school no H&S hard as nails blokes pah no to masks & fume extraction etc etc!

The pony tail guy was a highly skilled chassis welder on Nortons motorcycles & custom motorcycle fabricator for years, no doubt he has skills way way beyond the monkey that originally welded the Lambo chassis together, as standard it looked absolutely ste like bird ste in many places although its a fair shout that the internal Webbs can't be welded up so to me they should have been internally sleeved or plated over the top to recover lost strength.... Guess Matt makes the call on things like that...

There was a mention of some external support plates but I can't recall if they said it in respect of replicating what was originally there or providing extra support.

I understand what everyone is saying about how safe the car is. However the car isnt worth anything now,no one will buy it and clearly he loves it so is fixing it for himself to drive. In that case he accepts the risk. He isnt selling it on, and I doubt he will raffle it either.

Hes a young man and isnt war torn like some of us older guys that have been down this road, got the scars to provie it Christ when I was young I rebuilt a crashed Peugoet 306 cabriolet with cable ties once :-) Yeah it wasnt that safe but hey ho. I had until the next MOT to use it and I accepted the risk of it beening dangerous. I drove my seat ibizia around for a while with clamps on 3 of the brake pipes due to waiting for parts. Yep stupid as f*&K but when young your invicible.

Matt himself accepts that cutting chassis rails isnt the best way forward and is trying to make it as safe as possible but using the best teams he can. Those welds looked amazing. Some really skilled dudes there. Looking at the stock welds you cant say it was any better from the factory. Mat even mentioned how some of the key struct bent / snapped in the crash. Ever looked at Tesla welds ? Awful ! Maybe its a western issue as if you look at youtube videos from china where crashed cars are repaired you will see that cut/ shuts are common.

I must have been half asleep watching the video as I really didn't see any poor repair practices. In fairness, I was half asleep and distracted by just how much more work they've managed to do than I have on my project.

I guess he doesn't spend a load of time putting inane responses in online forums.

The external support plates were from factory. Mat clearly said they were going to replicate them on the side that was repaired.

I see nothing dodgy with what they have done and I can't envisage the external support that has been used (the welders) wanting to be associated with anything other than a quality repair.

It's not a cut and shut. Cut and shuts are structurally weak bodge-jobs, this isn't.

Not sure I agree, yes the repair is welded externally but the main section has internal strengthening which has not been restored, so this to me is nowhere near as strong as the factory chassis.

I enjoyed the video and fully respect he had someone else do the repairs but people saying it will be ok need to understand that how this has been repaired is not the correct way, they offer complete sections for a very good reason.

[The OG Jester]

I don't think this has been mentioned but the front and rear chassis parts that were damaged.....are the not meant to crumple and snap off to take the impact away from the main tub? If the main tub it still intact and structurally sound, another crash isn't going to be any worse (given the same speed/contact etc) than his first crash?

The only welding I'm more familiar with and knowledgeable about is plastic welding where the weld is stronger than the extruded pipe sections. Is the same not for steel and aluminum? Is it not more likely to snap on a straight section than the weld just like it did on the original crash?

[simon_harris]

But what you don't know is what else (granted if anything) has been done to address that.

These guys look like they know what they are doing, this hasn't been an exercise in doing it on a budget so while it may not have been shown in the video that could well have been addressed with some other solution.

Yes, theoretically the weld should be stronger than the parent metal so if anything fails it’ll be the straight section rather than the welded part.

Jesus, I didn't expect so many MA fan boys to get bum hurt and start picking out my grammar, saddos

It was a genuine question.

Thanks to the one that responded with an actual answer though.

But we can only discuss what we're shown.

True enough but we can draw inferences from what he did do and what was shown. He bought in the proper guys to do the repairs in the proper way, not some mate that has done a bit of ally welding and has a TIG welder. You only have to look at the jigs they were fabricating to make sure everything went back in the right place to know that they weren't cutting any corners, so while we weren't shown the full details of the repair I expect there was more that wasn't shown due to the length of the video.

[Muzzer79]

Exactly, you can't question the repair on the basis that we didn't see all of the detail.

It's an entertainment video, not a documentary.

[Retro_Jim]

I've not watched the video yet but I have had a few welding sessions at the machine shop from Bob. He does know his stuff and watching him weld a titanium exhaust as a demonstration was impressive.

It doesn't matter how neatly it was welded, you still can't weld the internal webs of those extrusions they cut through, and those welds will be the weak point if it takes another knock.

That would bother me. I wonder if they didn't know about the internal structure until they cut into it, by which time it was too late.

They could have cut back the outer skin if they had wanted, and gained access to the internal webs. Looking at the guys doing the job, and the wealth of the client, I think they made an engineering judgement, and decided the plating on the outside was enough. I'm sure if they had said to Mat that they needed to cut back, he would have been okay with that.

There's only one way to test the strength of the repair, and if Mat drives on slicks in the rain again, we may find out how good the repair was.

Personally, I'm of the opinion that these structures are very technically designed and a repair that is too strong will not deform as designed in a crash, and a repair that is too weak will break too easily. The only way to get it right is to not repair-by-repair, but to repair-by-replacement. That doesn't mean that I don't repair-by-repair. It just means that I know that I am taking a risk by doing so. I tend to over-strengthen than under strengthen if possible, unless I'm "adding lightness" .

I know they’re road legal these cup tyres, but how on earth are they!

When you saw the tyre (I’ve never seen these before) on the video there’s hardly any tread whatsoever and makes a mockery of my mot failure because of a small area on the edge being at 1.5mm where the rest was well over 3mm.

Bit of a cross creator link but the GT3 Matt did up in Florida featured on the Wheeler Dealers program this week where they went to see Tavarish and the McLaren P1 he currently has. Mike Brewer seemed to love the car.
