Really? .020 by eye? With the magnetic pull trying to zero the gap? oookaaaaay...
Add to that a Dremel, probably the most useful tool ever.
Metal lathe is nice, that's next on the list after I get a MIG.
A good tap and die set is very useful too.
None of those are really necessary except the maybe the Dremel, depends on what you're doing really.
