Only because you asked.

IMHO it looks like the spacing on the speed numbers is a little off for some of them, and I
think the (bottom) zero in the vacuum section needs to move just a little left. Do you have
a (geometric) compass? That might make the spacing in the speedo section a lot simpler.
Oh, and for the record, I think you've done a great job. Hard tedious work. Well done!
