edkin Posted October 28, 2019 Posted October 28, 2019 I have discovered a hairline crack on the chainstay making up the subassembly on my bike. Probably caused by a siezed bearing. The bike is a Ghost so I don't think I'll find a new sub assembly very easy. Does anybody know and can recommend somebody that can do a decent Aluminium weld in the Cape Town area? Alternatively, any other ideas? Any Advice (except to go vegan) will be appreciated.

dave303e Posted October 28, 2019 Posted October 28, 2019 Maybe if you go vegan it will fix itself? And the whole world according to Hamilton. If you don't come right in CT, Tigco Tech welding in Centurion, Gauteng will no doubt be able to sort it for you.

BuffsVintageBikes Posted October 28, 2019 Posted October 28, 2019 The chances of an aluminum weld holding is very slim. Rather, the weld will probably hold but it will often crack again next to the weld. If you want to take the chance, I've got a friend who does laser welding, which is probably your best bet there. His name is Erich and their company is called Luxus Jewelers, they are based near Stodels.

Done properly, it shouldn't crack next to the weld. If it does then there is something else wrong. We weld aircraft parts!!!!!! and that is an approved repair by the OEM.

Hairy Posted October 28, 2019 Posted October 28, 2019 Keeping an eye on this ... have a nice trail bike frame that could do with a weld on the crack.
love2fly Posted October 28, 2019 Posted October 28, 2019 My brother had the chainstay of his tandem welded, held up just fine for the 3 years he kept it and YES he did tell the buyer...The chances of an aluminum weld holding is very slim.

The other issue is putting too much heat into the weld - this is a common problem for less than really competent tig welders (me included) That said - hubber AMPANDY is pretty good at tig work - worth pinging him to see where in the world he is working.
