The top arm wasn't doing the job properly and I could see that it's
made in two parts (top and bottom) which were separating, so I took it
off and prised it apart completely. I thought it might click back
together but no - damned thing was glued and prising simply unstuck
the stuck glue (IYSWIM). Off to the orange shed for something to
stick it back together and found some Evostick 'Serious Glue', which
was the only thing that claimed to work at high temperatures and in
the wet (superglues etc all warn off use in water). Stuck it back
together, waited 24hr to get a full strength bond. Ran the dishwasher
tonight......and there was the bottom half of the arm sitting in the
bottom tray.
Ironically, a new arm (already ordered from Partsmaster) was only 2.99
(plus the same in P+P, of course), compared with the fiver for the
glue.
Somehow I suspect that a solventy-thing (like model aeroplane glue)
would do a better job as, to some extent, it would weld the plastic (I
know straight chloroform works well for perspex, for example), but
does anyone have any positive experience of trying to do this or is it
just a no-go?
