That is hilarious. MEK. Now that is genuine nasty. We had to dispose of a
quart of this stuff about 15 years ago.
Reminds me of the old trick on a winter construction site when you send the
new guy out to get Herman Nelson. Poor bugger runs all over the site asking
for Herman Nelson (for those of you who live in warmer climates, a Herman
Nelson is a type of diesel-fired industrial heater) and the older guys keep
sending him hither and yon.....Similar set up to the sky crane quest.
A piece of wood screwed to an ABS pad which is then glued to the top of the
lid may be the trick and obviates the need to drill a hole in the lid.
cheers,
Robert
