    Default hardened shaft repair

    Hi all, i have an Ozito brand multi head cordless tool, and the chainsaw head component suffered a snapped drive shaft due to a slight kickback. the internal components look like reasonable quality, though badly designed in not having some shear point in the design. anyhow….i am going to try a tig repair and just after some reassurance that it is possible. what filler rod would be best. i have 316L stainless and comweld high test or woul something else be better. i have ground the ends to a V in preparation and just awaiting some encouragement. it is only a home use machine but would be a shame to junk it. shaft is approximately 8mm dia.CBB8870E-E8FF-4C4A-A8E1-84B2B04CAC23.jpg483BF918-F11B-44A4-9A47-07D4FCEEE08C.jpg

    I am not a welder although have completed very similar projects in the past I would go with hitest if you weld with any thing other than TIG you most likely need to re case harden ( in my experience being Ozito it will only be case hardened )

    I assume it is past it's 5 year warranty

    Alternative option, since it's Ozito, there's a good chance you could get Bunnings to special order in that part. I've done so in the past, when the cutting head in my frond chomper got chewed up.

    thanks china, yes the warranty has gone. it looks like it broke along a fault line of sorts. i should be able to get a decent weld on it though.
