    Default Small welding job need advice if its worth doing ....

    Hi all,
    I've got a 10 year old fan.
    It's heavy duty compared to todays fans.

    It circulates a lot of air.

    The fan blade has come off its hub/spindle (?)

    Can you tell me by the pics if it can be repair welded and if its worth having it done?

    Thanks heaps in advance.

    Fixable, yes, but it would probably entail making a new collar from steel on a lathe and welding that on - the old collar looks like a pot metal casting. If you had to pay someone for the repair it would probably exceed the cost of a new fan.

    You may be able to kludge something up from MDF, there are plenty of people who create attachments for motors that way.

    Is the fitting that came off the fan threaded? If not, then maybe a simple mild steel hex bolt drilled out to size and tack welded on would do the same?

    Regards

    Barry by the look of it, welding is not an option but can be repaired by making up a stepped bush that will go in and have a thin left hand threaded nut screwed on the other side. It might be worth posting this thread in the metal work section, as that is where most of the "turners" hang out. If no one offers, send me a PM and I'll have a crack at it. The hole in the fan will need to be filed to make it round so the boss will fit.

    Hi Barry even if it can be fixed the blade would need to be balanced or could be like 10 pairs of wet jeans in a washing machine on fast spin.

    Thanks heaps to all.

    Few more pics to clarify.

    Was just thinking to replace this fan might be quite expensive the get the same high velocity type.
    So I might continue to pursue.

    Had the right screw in my hand a few hours ago.
    Don't know what happened to it.
    But you get the idea how the fan was attached.

    Not threaded.

    Personally I'd put a flat on the side of the thread - that way it will be keyed to the blade.
    Probably the simplest way to repair though, although if I had the blade I'd be temped to swage a lip over like the original.

    Good idea about the flat, and the swage, didn't think of that. Thanks Michael .

    Default Generous forum member assistance successful

    A very generous member helped in sorting this out.

    Quality professional repair made me humble to witness how easy he made it look.

    Really happy with the work and being successful in salvaging this fan for another 10 years use.

    Will add pics as soon as me head clears.
