Thanks for the nice words guys. I have had bad luck with aftermarket sheet metal in the past, so I am trying to avoid buying any. Hope my quarters don't have too many surprises.
As far as getting my son involved, it is a little hard to find projects he can help with that aren't too complicated for a seven year old. Would like for him to take an interest in this stuff and pick up a skill. We'll see how he progresses. Working on a T/A is way cooler than video games if you ask me.
