Given that the alloy is cast onto the metal liner on those drums you have to question pressing or shrinking an insert into the the drum to repair it . I wonder how you would stand with an insurance company or inspection after an RTA ? Personally I would would try to get an original from the likes of DK or GovnorsBridge . Or am I just being a 'wuss' and it's known acceptable practice? Is the cast onto surface on the original steel part profiled or knurled in any way to give better grip between the alloy and the steel ?
