One of the wedges on my old lump hammer has come out. Before it came out
completely I had a look and it seemed to be made of wood (this is an old
Chinese(?) 1kg hammer that I've had for over 20 years, with two wedges
at right-angles to each other). I could replace it, but sets of metal
wedges - nearly all of which I'll never need - seem to cost nearly as
much as a new hammer. Any ideas for a functional substitute?

Far be it from me to divert attention from a fixing job ... but may I
recommend the odd car boot sale? You may not find wedges there, but
you're almost certain to find whole stalls of ancient (therefore
fantastic quality) tools - usually filthy, and usually being sold by
someone who'd just like to go home a kilo or two lighter than when he
came, and get a quid or two into the bargain.
