How fea­si­ble is it to re­place a steel tank with an alu­minium copy?

Richard Colledge has had enough of try­ing to find good con­di­tion 1970s Kawasaki tanks. “All the ones you see now seem to have been lined with sealer or are too rusty to be of use,” he says. Could you rec­om­mend a com­pany who’d be able to make a copy of an orig­i­nal tank in alu­minium com­plete with orig­i­nal tap fit­tings, etc?”

Good idea, but I wasn’t sure it’d be pos­si­ble to get right. Be­ing thin­ner and less duc­tile, sheet steel tanks have sharp pro­files that can­not eas­ily be du­pli­cated us­ing alum seams on Ja­panese tank repli­cate and al­loy tank Monza snap-down caps ma­chined neck be­cause strong enough to make fit­ting. It’s un­likely you the orig­i­nal Kawasaki c prom­i­nent tank-top feat I rang Rich at Tab 2 C (01974 821469) for his o and he con­firmed my fe “We avoid do­ing one-of tanks,” he said, “It’s im com­pletely repli­cate a steel press­ing in alu­minium. We could mod­ify one of our tank shells with a base tai­lored to fit Richard’s Kawasaki, but it wouldn’t look stan­dard.” Aside from con­tin­u­ing the search for a good orig­i­nal tank, Richard’s other op­tion is to have his ex­ist­ing one pro­fes­sion­ally re­con­di­tioned. Since men­tion­ing my Norvin tank re­pairs, I’ve re­ceived a cou­ple of rec­om­men­da­tions . The first is Roberts, who tered and rusty ank suc­cess­fully hed by nd Cur­va­tures in ham (01159 and John Dunn d to say he’d been d with the work s Nor­ton tank by Mo­tor­cy­cles in t Dun­mow, Es­sex 1 876027).

Smooth curves of this En­field tank made repli­ca­tion in al­loy eas­ier than for some other bikes
