A problem I run into occasionally is scribing lines precisely enough when doing layout. When using straightedges and an ordinary carbide scriber I find that I get about five thousandths precision (+/- 0.005") whereas I would really like to be more within five tenths (+/- 0.0005") of the target dimension.
For example, let's say I have two pins and I want to scribe a line tangential to the two pins. If I lay a straightedge against the pins and scribe the lines along the straightedge I find it difficult to get within tenths of the true tangent.
How is it possible for me to up my game and get my lines tighter?
