tip for when your making zinc profle.once youve cut your profle out with tin snips,and after youve used a file to get it within a couple of mil.
firstly i find the best way to transfer your profile on paper to your zinc is to mix some shellac flakes with meths,set fire to it,once the meths is burned off and whilst sticky just stick your paper on to the zinc it sets like shite to the blanket.
use the side of a nail to wear down the edges this works a treat in getting rid of any tiny defects after youve had the file on it, in the template before you run it on a bench.it gets the edges of the template lovley and smooth,minus any tiny nicks,that would obously show on your mould.
you dont need to buy any profile make them your self, on squared paper and just transfer them onto your zinc profile and tack it to a shoe and a stock then away you go.
