tail light update
after a few days of research i found out what the orginal tail light housings are made of their are 2 choices in material
one is zamak 3 this is normally used with injection molding it requires high pressure and set up fairly quick
the other is za-8 this is a combination zinc and 8% aluminum mixture the higher aluminum content allows this to stay fluid longer and can be pour in with a ladle
both materials have are pretty much equal except for the fluidity time
i bought za-8 because this is what harley uses for their tail lights so i know this will chrome real good
and after a few day waiting the material has arrived this is what za-8 looks like
za-8 melts at 850 -900 degrees
requires no degasser or fluxes
the steel mold will have to be preheated to 300 - 400 degrees
for mold release either actylene tourch soot or graphite powder i also read people use talcum powder
i am waiting on a 2 degree tappered end mill to arrive so i can cut the tapper on the little block i added to the mold so i will not have to cut out the liscence plate lens window then the mold is finish and i can try making one
