Thanks for the info guys.
Firstly I am new here, I noticed my post was moved by a ‘mod’ to the general signs.
My query was to do with cut letter so I put it in the routering section, is that not correct? as locators refer only to routered shapes and letters?
I don’t use brass locators as the only hold to the letter is the glue, so sometimes the shearing action is too much for the glue.
I have just spoken to SNAPFIX seen their advert in a sign mag, they told me their products are lifetime guaranteed, being both frost and UV resistant, so looks as if I may go down that root, although I will have to change the males on most jobs.
They told me the cup is made of alchethene, not polypropolene like simplefix
all interesting stuff.
