I'm glad to hear that the nerves are working properly. Nerves are one of the toughest things for the surgeons to fix and something the body is not very aggressive about mending. Despite the damage and pain, you are truely blessed to still have your arm and be in a position for a full recovery. Good luck with physical therapy. It is REALLY important to get that arm functioning up to its potential ASAP. The nature tendency is to favor the other arm and never really force the weakened one to reach its full potential.
I'll vote for posting some pics, especially if you can put a warning on them for the squeemish. CNCZone has a section devoted to safety and it includes some real horror stories and close calls. The idea is to remind everyone of the dangers involved in heavy machinery and other elements of these hobbies. I have had some close calls myself with mowers, bandsaws, fire, heights, chain drives, electrocution. Before I approach any dangerous job or powerful machine I mentally picture some of my close calls. It help me be mindful.
One of my favorite close calls was when I pinched the two prongs of a free standing high voltage tack welder between my index finger and thumb. I thought the two prongs came together to apply force, not voltage. I pushed down on the foot peddle thinking the prongs would come together - they did but not with any force. Then I smelled burnt flesh. Luckily the current just charred a little channel through the surface of my skin and didn't vaporize the finger tips.
Your story may save someone's life or just a finger, but either way it is worth it.
