Title: Casting Resin Parts
Post by: canuck750 on October 24, 2017, 10:46:59 AM
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

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04888_zpseqstnnnn.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04888_zpseqstnnnn.jpg.html)

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

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04891_zpsimskeczf.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04891_zpsimskeczf.jpg.html)

Once cured peel off the clay base, clean the original lens and reinstall it

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04893_zpsamymcf40.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04893_zpsamymcf40.jpg.html)

Spray with mold release

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04894_zpskefef7u5.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04894_zpskefef7u5.jpg.html)

Make a fill tube and a vent tube

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04895_zps5eeqvdln.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04895_zps5eeqvdln.jpg.html)

Fill the upper half of the mold with latex

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04896_zps4tfourrw.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04896_zps4tfourrw.jpg.html)

Tap the mold to get any bubbles out

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04898_zps227uwnzp.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04898_zps227uwnzp.jpg.html)

Once cured separate the mold, remove the original and place the two mold sections back in the drain pipe

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04899_zpsllwsyjbl.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04899_zpsllwsyjbl.jpg.html)

Clamp the tow sections together, just finger tight to not deform the latex

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04994_zpsux5xwvpj.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04994_zpsux5xwvpj.jpg.html)

Clear casting resin and amber die

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04901_zpsvbdavdc5.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04901_zpsvbdavdc5.jpg.html)

Manufacturer recommends mixing by weight

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04902_zpslknqym9t.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04902_zpslknqym9t.jpg.html)

Fill with a syringe

(http://i249.photobucket.com/albums/gg217/canuck750/Resin%20Casting/DSC04904_zpsc3fskpbr.jpg) (http://s249.photobucket.com/user/canuck750/media/Resin%20Casting/DSC04904_zpsc3fskpbr.jpg.html)

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

Nice work! Do you have to drill out  the screw holes?

Yes, some resin gets into the screw hole through the fill and vent

Or the little "wings" on the ends of the taillight lens of the same bike.
