Robot Hand

This is the cool robot hand my 8 year old son built. He did 90% of the welding and cutting, and I just did the grinder part (because bad things can happen real fast on a grinder). He has been watching the whole time I built the bike and I decided that it was time for him to try out welding. We got the idea from Instruables, and scaled it down to his size. We spent a total of about 8 hours on it.
