Q. If I order a 24mm drill, can I be assured that it will drill out slightly larger than 24mm, or will it end up being an interference fit and I will struggle to get the weight on the shaft? If so I will have to order a 25mm drill.
many thanks

Hello M,
You'll be fine with a 24mm drill (in a drill press with the work well clamped), BUT it would be better if you had a friend with a lathe (and boring bar). Then there's no need for a 24mm drill and you could then tune for whatever degree of fit you prefer and add a chamfer to the hole to ease the fit to the shaft.
Best
