Agreed on that one. Two days ago, I repaired the
broken-off "tang" on

a bezel to a 3.5" drive. No more than about 3mm
wide and 2mm thick,
solvent cement did a perfect job in restoring the part. I used a
hobby-variety brand called "Tenax 7.R'. Dichloromethane is also
referred to as "methyl chloride". Done well, the repair is invisible
Is it? I must admit I never realy used the traditional names, but I
thought methyl chloride was CH_3.Cl and methylene chloride ==
dichloromethane == CH_2.Cl_2
If you have space, and an 'invisible side' to the repair (say the inside
of the case) you can make it even stringer ny cutting a piece of cototn
fablric (e.g. an old shirt) to cover the repari, putting it on, and
'painting' it lberally with the solvemt. Oce the plastic has softened,
force the fabric into it. Let hte solvent evaporate, and it should be
good as new.
One warning,.. If the plastic hs becoem weak/brittle with age (as many
do), this rerpair will not reverse that. So the part may well fial agian,
in a different place, perhaps, before long.
