Yes, I've known a few (well, someone had to say it)

I tend to buy my wheels from Abtec. The 32mm/1.25" thing is a problem. I've been caught out by it before. My solution was to open the bore of the affected wheels with a 32mm Rotabroach cutter, by hand (Que gasps of horror and warnings of explosions by the ignoramuses in the audience).

New wheels should come with a set of plastic (these days) bushes of various sizes. There was a time when lead bushes had to be made to fit wheel and grinder shaft. It's possible that the bushes have to be purchased separately, can't remember, long time since last purchased a new wheel. I certainly wouldn't buy any old junk wheel from the second hand tool trade. Cannot afford to take the risk of a shatter.

Try Midland Abrasives Ltd, Hockley, Birmingham (0121 687 1135) – Very helpful people and will modify wheels to your requirements. I needed a new wheel for my toolpost grinder and they sent me one they had cut down from a metric size wheel as the original o/d was obsolete. This they did at no extra cost. They also recommend the grit and bond you require if you tell them what you are mainly interested in grinding.

No connections other than a very satisfied customer.

I would be considering reaming the parts to 32.00mm. Might not, of course, depending on the situation ‘in the flesh’.

Further to my previous post, it could have been Cromwell Tools

Smart move I say. One thing you never want to do is fit a grinding wheel onto a spindle/arbor that it's a tight fit onto. I turned an arbor once for a wheel and it was a fairly snug, but not terribly tight fit. It (the wheel) broke whilst I was fitting it. A very scary lesson learned way back, I was shocked at the ease which the wheel shattered.

Mike, Take it out carefully with an adjustable reamer.
