Morning,
I've found some steel wheels that will fit my Caddy exactly how I want. The only problem is the centre bore is slightly too small. The wheels have a 56.6mm centre bore and the Caddy hub is 57.1mm. What would be the best way to remove the 0.5mm of metal to get them to fit?
Cheers,
Sammo

Tbh i think you safely just remove that with a dremel or air die grinder with a paper roll in like a spiraband .
Just go around slowly and evenly

As the amount of metal you're removing is so small another alternative might be an abrasive flapwheel in drill or grinder. For larger diameter holes it's a bit easier to get a more regular finish than with a dremel. I've done it with my dremel but it's hard to get a regular circumference - I always end up with bits where I've gone a bit too deep.

I've got a die grinder bit for the Dremel but I think it would end up being uneven if I used that. A round file sounds like it could be the way forwards.

I've used the top of a traffic cone for something similar in the past (panel work though, not on wheel bores). Worked very well. I did need to keep replacing the abrasive strips fairly regularly but it did a decent and accurate job with minimum effort...  The important bit is packing the cone though. I think I used polyfilla. It just about lasted long enough, but something a bit more dense and robust would be better. |

Someone on another forum just suggested using a cylinder hone to hone the excess material out. I don't know if it would be abrasive enough though.

A zirconium spiraband will do it thats what i meant , but a half round file will save you buying something and there is little chance of messing it up and will probably be just as quick .

Don´t file only on one spot, let the file grind along the curve. Thats the bit that would concern me. By pulling a file back and forth manually and moving around the wheel, it's going to be really difficult to be accurate. if there was some way of having the wheel spin at a moderate speed, like on a turntable or something, and then you offer up the half-round to the turning edge and just stroke it back and forth on a rotating edge it would be quicker and also more uniform. I'm racking my brains trying to think how I would get a car wheel spinning at moderate speed with no workshop, and without taking the washing machine apart.  |

These are brand new so won't have tyre's either. I think the file is going to be the way to go.

Moving the file and not the wheel will be easier and easier on your muscles .
You could cover the area to be files with marker and keep going around till its all gone , so you know where you have got down to and then repeat if needed .
We are talking .25 mm all around so it really will not take long at all .

If you are lazy like me, you could get someone to do it on a lathe (bit excessive) or buy a tyre fitter a drink and borrow the machine they use to fit tyres. Get it spinning and file it, shouldn't take long.
All that said, it doesn't have to be very accurate in reality.
