a few newspaper articles the shop was in back in the 60s

cleaning out my computer again

cleaning out a few prism /tank bike pics that got on the net  figured i would postem before their gone

i dont know who built the red honda but its real nice

done at last

   well i can finally say i am finished  with the mold

   yesterday  i  added on the little square that will make a notch in the housing  for  the liscence plate  lens  i screwed it on and the cut it to a 2 degree taper to match mold top half    i  also removed an inch off the bottom to get ride of some weight

  the orginal housing  fits the mold so well that the tapers lock  to the piont i have to pry it off

  after seeing how hard it is to get the orginal housing off the mold  cory and i added the  aluminum plate  with ejector pins  on the four corners of the housing  so i wont have to pry  the housings off         i will be able to hit the corner of the mold with a rubber mallet and the ejector pins should just push the housing up enought to take it off by hand

hopefully in a day or 2  i will get to try casting a housings

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

ariel square four choppers
