A bit off piste here, My set of Triumph dolomite Alloy rear wheels seem a bit lost in the arches, the arches would possibly take another 30mm of wheel plus tires, does anybody in this country widen cast alloys, and, I have seen it done with a TUV cert too. My thoughts seem to be running along using 4 wheels to make 2, Fortunately the barrels/hoops of the wheel seem to be nigh on parallel, part rims off 2 wheels leaving 30mm from the rim face, also at the same time leave a machined spigot for location, do the same with the other 2, but machining to the face of the wheel, and machine an opposing spigot for location, pop one on the other, and I should have widened the wheel 30mm, all is needed is a good welder to TIG them together..........  is there anybody in the UK offering this service? |

I’ve seen someone narrow some but I don’t think anyone offers it as a service.
You’re probably easier and safer split rim converting them, as the joining bits back together issue goes away then.

There's a guy on the Manta club Facebook page that turns alloys into wider/large diameter wheels, Pawl Burt - don't know if it might be worth contacting him..

Personally, I wouldn't use repaired alloys, let alone widened ones! Even more so if you will be using them as depicted in your avatar!!! Any welding will alter the structural integrity of the surrounding metal due to the heat, unless they are retreated after the work. If you need to fill the arches you could consider spacers. 25mm would not increase the the stress on the bearings by much and a lot cheaper then widening the wheels :-) Or look on ebay etc for a suitable set as these will be safer (IMO) and probably cheaper than getting your wheels widened.

Online I've seen one piece alloys that were made into three piece ones so you then get to choose the barrel width of your choice. Probably costs loads though.

Hi, Yes it's not just the HAZ (heat affected zone) but is the filler rod the same 'recipe or mixture' as the wheels alloy. Colin |

Ive done exactly what your suggesting before. Never bothered actually using the wheels but no reason why it wont work if done properly.

A couple of posters above have mentioned 3-piece converting them, this may be a good option as it does not require welding an unknown alloy. It is quite pricey though, £2500-£4k would probably be the ballpark (retail price on just the lips and barrels is currently about £1500 for a full set before machining and hardware). You will also end up with a wheel that is usually a little larger diameter than stock by one or more inches depending on the wheel design. Another option may be to get a fully bespoke wheel made, using your existing design as inspiration. You can then build it to any size you like, even tweak the design to your taste. Rimscarnated offer that option, in 1, 2, and 3-piece designs: rimscarnated.com/collections/design-your-own/products/design-your-own-1 |

I think I'm just mulling ideas at the moment, Normalising the rim after welding would not be an issue, I would guess they are probably made from LM 20 or 24, but knowing BMC, they are probably made from LM 2,
I did most of my apprenticeship working for a large foundry group, which walking thru the yard, there would be stacks of F1 wheels & suspension parts stress relieving themselves after heat treatment, the other spinoff company that we had was at the Kent Alloys,
The Americans seem to weld Hoops onto Centres without even a nod to heat treatment.

I’ve done it once on a pair of Fiat x19 wheels. The standard lip was cut off and i Tig welded an outer lip from another wheel back on from a wheel with more dish. This was not a precision job but my brother raced the car for a few seasons with no issue.
When I tacked the lip on it was amazing to watch how much it would pull, even breaking some of the other tacks. Machining a step may help but wheels are generally not that thick to get a good step there.

Don't want to start an argument, but the talk about a heat affected zone is the same when welding in steal and not many people are worried about that :-) I have never heard of a cracked banded wheel and regarding aluminium wheels I have seen plenty that were welded for repair with no treatment after.
I'm not saying that it's the case here, but sometimes carbuilding is handled like it's rocket science, it's not, and sometimes it stops people's creativity.
Best regards,
David
