I dont take many before pics, I tend not to like being reminded of how bad many of my tools were when I got them, plus Im terrible about remembering to take pics in general.
Here's one of the more dramatic changes, my Buffalo 10" camelback. I literally tripped over it in a shed, mostly buried in the mud. I dont have a pic of it reassembled and its currently sitting in my brother's basement until I find or fab a matching 3-step flatbelt pulley.
My Elite fully mechanical (not hydraulic) floor jack that is now decorating a buyer's wall.
And for diversity, a hammer I got in a lot of body tools. Being the cheap SOB that I am, I cannot let a good hammer go to waste, even covered in bondo. 5 mins with the wire wheel revealed a really nice hammer.
