Well Gareth
That's a very nice birthday present! ………….of course , for pretty much the same money, you could set him up with a lathe, milling machine etc. then all your future "what to buy him" problems are solved for ever. Just ask anyone on this site if their workshop is fully equipped and they have all the tools and machinery that they could possibly want!
It would too, I'm sure, be of benefit to you as, with a workshop, pretty much anything can be fixed ( at least that's what all my neighbours seem to think!)
Regards
Norman
