I would like to know a price if you plan on it?

Tecum, who cares if you have to use a chart if need be. What I spine is for my wts and I know what I'm looking for without having to check charts.
And honestly I have more faith in keeping calibration of a dial indicator than something with a needle pointer thingy.

That looks great,Mike,Thanks for posting it!!

Hmm, I actually like it.  Simple with no built in design flaws.  Good job sir.
