+1 I have picked up a couple of projects where I realized they were really too low end for me to mess around with. So I put them on C/L, at a low price, as "projects". There is a price around here where people will buy just about anything.

Also what happens when we measure once...

By the way, when old grease coagulates in in your bottom bracket you can scoop it out and ad it to bacon grease when you're making hash browns.

Here's a time-saver for the bikes that just aren't worth a teardown, i.e. the more disposable bikes or where a cottered crankarm is discouraging proper renewal of order in the bb:
You can literally grease a hub or bottom bracket without touching a wrench in most cases, and the tapered tip slips into cable housings and creates somewhat of a seal, for use with whatever spray-cleaner or lube is needed.
I have about 25 different aerosol and squeeze bottles with this kind of applicator since it makes lubing more effective and less messy.
I just spin the tube over a lighter, and draw the heated tubing into a capillary, then cut to length.
You can get two applicator tubes out of one pull, just cut the capillary with a sharp razor or scissors.
One caution, a heavy flow from the spray can may blow the tube out of the nozzle, especially as the capillary is made longer and/or thinner. Different tubings and temperatures can give different sizes and thus flow rates.
A fresh, square cut off of the blunt end of the tube usually restores a tighter fit in the can's nozzle.
My aerosol cans seem to last longer with these tubes attached, that's for sure, but for making hash browns, I just use the fresh stuff right out of the can. ;-)>

Or vice versa, use old bacon grease to service your bottom bracket.

I'm with him. I have tricks, but they're not shortcuts to profits, just easier ways to do what needs to be done.
I probably do a better job on other people's bikes than my own.
