The pulley wheel on my qualcast mower has broken. As the part is obsolete I was wondering if it would be possible to bond the two parts back together.

I was thinking of using Araldite or somthing like JB Weld.

It appears to be made of cast aluminium or something like.

Any advice would be most welcome.

Looks more like the V-belt has worn through the thinnest part of the casting. That would make bonding it back together a very tricky proposition.
Pending a look at the side not shown in your photo, I would bore out the centre of the cogged wheel, and make a new spindle that bolts in place. But I would price a new mower first, as that's got to be at least a couple of hours work, assuming that a lathe is available.

Worth a post on Freecycle? A long shot, I know, but somebody might have an otherwise dead mpower of similar model. Or, in desperation, eBay?

Also if you are on FB have a look at the sale/swap/freecycle sections, I have often seen mowers for spares or repair.

i've never had good long term results with aluminium and epoxy no matter how clean i got the surfaces.  solder would be better - clamp them gently together, heat them up and feed solder into the cracks so it melts and seeps in.

I wish my lawnmower was broken.

Guess what I've been nagged into doing as the weather is nice

Would that be plumbers solder, and would a blowlamp be sufficient for heating?

I've got one of these kits somewhere, but never used it.  It was recommended to me ages ago for a repair on a motorbike.

Hmmm, most of the people I've known as "naturalists" I prefer with their kit ON.

google "soldering aluminium" there's lots of advice, not all the same . careful with a blow torch it is easily capable of melting aluminium (660C).

I was given a couple of sticks of special solder-like substance for repairing aluminium once. Wonder if I've still got it somewhere?

Not Lumiweld was it?

I'm trying to think. Doesn't ring a bell. Some guy was doing the rounds of the kit car shows demonstrating it.

I`ve just found some in the shed, it`s like large sticks of solder that you`re supposed to be able to use with a blowtorch. It was recommended for repairing engine casings on bikes and stuff like that.
