Here you go Chuck, I think I had this in one of my previous V7 Sport builds, a recap
There are a lot of good videos on line that explain this far better than I can but here is a quick view of what I did
This mold is for an Aprilia amber signal lens
The mold is formed in a section of white plastic drain pipe, two pieces of plywood joined by bolts hold it all together for pouring the resin
You will need some modeling clay to form a base to set the original onto and seal the base of the mold, acorn nuts are for mate pins of the upper half of the mold to follow
Mix enough latex mold to fill the 1st half of the pipe section
A pro uses a vacume pump to get the bubble out, tap the mold to get bubbles out and let it cure
Once cured peel off the clay base, clean the original lens and reinstall it
Spray with mold release
Make a fill tube and a vent tube
Fill the upper half of the mold with latex
Tap the mold to get any bubbles out
Once cured separate the mold, remove the original and place the two mold sections back in the drain pipe
Clamp the tow sections together, just finger tight to not deform the latex
Clear casting resin and amber die
Manufacturer recommends mixing by weight
Fill with a syringe
Once cured remove the clamps, split the mold and pry out the copy lens
Results are dependent on getting the bubbles out and not having a leak, not perfect but presentable, every detail will be copied
Cheers
Jim
