What about rivets? Still available in many shapes and sizes in steel, copper and aluminium. Alternatively screws and nuts (stainless steel) for future maintainance. Cut new paper/thin carton gaskets and soak them well in heavy oil before fitting. Kees Oudesluijs NL [demime 1.01d removed an attachment of type text/x-vcard which had a name of coudesluijs.vcf]
