I am sorry that you felt the responses weren't what you had hoped for. But it's not about can it be done, or if so, how it can be done. There is more.
It's about whether it's advisable to be done (by a "amateur", a mate, a friend so presumably without personal liability cover) and if, in doing so, you expose yourself to being left without protection of insurance should it ever fail and injure a third party or, indeed, yourself.
Yes I am sure it can be done. But if it fails where is your protection? And because of that, as KTF says, just contact Jacksons and let them sort it.

Tyres guidance...and it is that it's not law...is BSAU159F...is fairly much as below that I've copied and pasted from an up to date internet source:
[FONT=&]BSAU159f states that no repairs are allowed in the sidewalls (these flex continuously and a repair is likely to fail), and the standard says repairs are not allowed on high speed Z-rated tyres.[/FONT]
[FONT=&]It says a tyre must be inspected by an expert for secondary damage (a nail which punctures the tread might also damage the sidewall inside), run-flat damage (determined by a darkened or marbled appearance inside the sidewall), exposed cords and so on.[/FONT]
[FONT=&]Michelin, however, is the only manufacturer that recommends that its Z rated tyres can be repaired in accordance with the previous BSAU159e.[/FONT]
[FONT=&]Repairs can only be made in the centre of the tread area, to within 25% of each side of the centre line.[/FONT]
[FONT=&]Only two repairs per tyre are allowed up to the J (62mph) speed rating, and one up to the V (over 130mph with 155mph maximum) speed rating. Up to the J rating, repairs no bigger than 6mm are allowed, and up to the V rating only up to 3mm is allowed.[/FONT]
[FONT=&]All repairs must be carried out with a mushroom-type plug, which fits into the puncture hole from the inside and bonds with the tyre by vulcanisation.[/FONT]
[FONT=&]Anything else and the BS says the tyre must be chucked. If your tyre repairer says the same and quotes similar reasons, he’s being honest.
Kwik-Fit and ATS, as far as I recall, patch tyres. They don't have the equipment to vulcanise but are "while you wait" folks. [/FONT]If you want a full blown vulcanising repair, go to a specialist, just like you would with anything else...don't ring Kwik-Fit or ATS.

It's not that I'd hoped for anything.
Nobody knows my background or my engineering experience.
I asked for any thoughts, and got them.
Calling it a day now on this thread, but thanks to all who responded with their educated and knowledgable views and genuine caveats.
If it is deemed to be an unsafe and dangerous proposal then it won't happen, for my sake primarily as well as others.

looking at the picture it has been poorly welded from the off, some of the weld has been built up ok but looking at the chunk missing its possibly cold lap but the lower portion of the weld looks like it is not equal to or greater than the wall thickness so it doesn't meet design requirements and I say this as guidance as its a picture and I cannot give accurate info off that, but you could get it tested properly, with x ray at a lab. first off I would speak to manufacturer and see what they say, the other thing is how old is the mod as I have not read the whole thread so sorry if i missed anything and did you buy it new, atb wayne.

It appears to be a bad weld to me. Cold lap with minimal fusion. The fillet seems to have dropped off showing the prep untouched. The section below is not full height and there is another section above that appears very low...have you sent this photo to the dealer/importer? I would have thought they would be in a hurry to exchange it for you.
Can you see any trace of weld penetration on the inside or just a dry joint line?

p.s. just seen Mereside's similar post...sorry for any repetition.

Bish - please do at least return to this thread when you have heard back from Jackson Rifles and let us know the outcome.

Oh yes , however we fell out because the mod wasnt welded straight and he told me to use a chainsaw file and file out the bit that was catching the bullets , I did not think that was appropriate, then he started to tell me about welding (I'm a coded welder) all I wanted was a replacement mod as the one I'd brought was faulty (it happens sometimes) anyway eventually he refunded me after I returned his faulty mod but not before he slammed the phone down on me thankfully he picked up again otherwise it would have been a long drive to sort it out.
i'm sure many people have had great service from him but my experience was the opposite hence I will not ever knowingly give him another penny.
sad really because we all have off days but his arrogance and inability to apologise has lost him a customer.
I've only had to deal with them once, and found them friendly and helpful. They sorted my faulty mod within a week, no trouble at all. I certainly would have no hesitation in dealing with them again.

all he had to do was replace the faulty moderator , simple !
and I'd still be spending money there , he agreed it was faulty by the way.
