Europa-List: Drive pin attachment to trim tab

[Andrew Sarangan <europaxs@myrealbox.com>]

The manual calls for the TP16 drive pin to be parallel to the trim tab hinge 
line.
The way I understand it, the "L"-shaped template is used for positioning the
pin relative to the hinge line, but it does not necessarily make them parallel.
I've heard of people using a level for this, but it's not clear to me how
that is done. Any clues or photos would be appreciated.

Thanks
