redneck tools for the hobbyist

Exactly what I'm talking about. I see big potential for this being a sticky for hobbyist who can't afford again expensive one-time used tools. Or don't want to lol
When I worked in the local Toyota service department many years ago, I made a front crank seal puller from a section of threaded pipe, a large nut and a bolt. I still have it. Will get a pic or two when I get home from work tonight. Is that the kinda stuff you're talkin about?
