If you want to make something watertight, or if two things have to remain together for life, you may want to use glue.
One of my favorites is EPOXY two-component glue. It's specifications are outstanding!
One rather big disadvantage is it's long curetime especially when you use small quantities (generaly the case). One drop can take 1 week to completely cure (harden).
Now the hint:
Put the needed quantity of the two component (50%-50%; using more hardener reduces curetime anyway but alters the good specs of the final product) in a non-metalic recipient (you can take the bottom of a plastic bottle). Don't mix (blend) the components yet. Put the recipient in the microwave (+- 40s at 600W). If you spot fumes switch off the microwave sooner. The components should be liquid as water right now.
Mixing of the components is very easy (piece of cake
)
Apply this homemade glue where needed (take off grease before with isopropanol; you may use another cleaner but isopropanol is safe for plastics!!!!).
Your curetime is reduced from one week to less than an hour!
Rate this one!
After I found out this behaviour and spoke with a German scientist, this microwave-procedure is used on industrial scale.
PS don't try *everything* out in the microwave; it could be dangerous. This hint however turns out to be safe. Keep an eye on the proces and stop the microwave when you see fumes.
