"If all you have is a hammer, everything looks like a nail".

So, if you want to do it yourself, and since you have no machine
tools, you're limited to the epoxy or babbit, no? Pick one, try it.
Not much to loose - you probably can't screw things up irreparably.

Or, you can take it to someone who does have the tools to do it
properly and pay them to do it. And ask for their recommendation.
