Mate, it'd be extremely risky trying to fix the thing as you rightly fear.
Maybe Sir should look at the Weber Original Kettle Premium Charcoal Barbecue 57 cm? For those who persist with olde Englishe units, that's 22.5" diameter. The cleaning device with which it is fitted is excellent; unfortunately Weber no longer supplies it for smaller barbi sizes. Costs around A$ 429.00 from what I've found on the interweb..
