Food processor plastic bowl seems to be polycarbonate and took a

polycarbonate that will wick into the crack and prevent it from
running.

Would it make sense to drill into the end of the crack for stress
relief or be more likely to make it worse?

Ideal glue would be food safe (so epoxy which might work isn't ideal).

ISTR that petrol or ether might be good solvents for polycarbonate but
I have a feeling they make it go brittle too which would be no use in
a food processor where the mechanical strength is important.

Any suggestions for the best glue to use here?


For fine cracks I always use superglue which has very good wixking
properties. I find it will also fill slightly wider cracks with a few
more coats. Easy to clean up with a scalpel.

and contains cyanide.

And is not toxic, excelt perhaps when inhaled while applying it.




What is really unpleasant is the fumes if it is heated, I did that
accidentally while using a belt sander.

Oh yes, fumes are instant asthma for me, whether in use, or when sanding.

not QUITE as bad as aluminium flux though. That is REALLY nasty
