Making wood chips for smoking

I’m doing an autumn prune in the orchard at the moment, and have a fair amount of fruit wood which I’d like to turn into wood chips to use in our smoker. I’m thinking of having a dedicated shredder/chipper for the purpose – it would only need to be smallish – but I’m concerned that a wood chipper would shred the timber too finely, and I’ll get mulch rather than chips. Am I going to have to process the wood by hand? I have arthritis so I’m hoping that’s not the case!

Does anyone have any suggestions for the best way for me to go about turning my prunings into chips? I’m in Australia, so brands of wood chippers here may be different from those available on the US, but I’d love some advice on what to look for if I do have to buy a machine.
