special tools this.... special tools that.... bah!



just use two pairs of vice-grips. and wear your sailing gloves.

pull REALLY hard on the line, and then snap (or have a helper snap) the visegrips onto the line just at the grommet to hold the tension while you set yourself for the next pull. and so on, and so on... walking the vicegrips down the line as you go.



Using this method I severely overtightened my H16 tramp. I've learned a gentler touch in the years since.
