ABS timing cover repair with Acetone

[sandcruiser]

On the advice of some online resources, I decided to tackle fixing my timing belt cover w/ some acetone and spare ABS scrap. It worked pretty well.

note that those holes are almost as big as the ball peen hammer's head.

Here is after:

and here is installed (though a crappy pic, sorry, better one pending)

Steve and all,

Thank you guys for recommending this repair. It hadn't occurred to me, but I'll definitely keep it in mind.

I saw Steve's handiwork in person and it is barely perceptible. In my opinion I think that with a little dressing it is possible to effect a completely invisible repair.

Steve, did you use any reinforcing glass to strengthen the repair?

I just used chunks of ABS and acetone. Nothing more.
I think that some fiberglass or something similar on the inside might lend more strength- but the timing belt cover shouldn't be seeing much impact anyway, so I just ran with it.

to clarify: I actually cut down ABS to almost fit the hole, then made a slurry and added that to the cut-down chunks, bonding them to the sides of the holes. It would have taken forever to just fill the hole with slurry as the slurry/glue/paste/gunk that I made was pretty thin.
