My Stanley combination square isn't even accurate enough for woodworking let alone metal working. I use it all the time for 'close enough' work but I need an accurate one now.
Do I need to go with a Starret to get an accurate one?
Which do you think is more useful; the 6 inch size or the 12 inch size?
How useful is the protractor attachment?
How useful is the center finding attachment?
What do you recommend?
