Serenity - April 12 2007
Hmm Pouring of this part is still not going well even after trying to poke out the air bubbles. So I decide to cutout an air channel to help the air come out
Here is the mould after I had cut the channel and poured.
And the results looks fairly good. Only a tiny air bubble but the lower portion is solid
So I first split the mould into two parts. Not something I wanted to do but necessary to carve in teh air channel
Here you can see the channel cut into the rubber better
And the styrene box keeps it in place as the resin cures
And I do the same with the second mould
It also has it's own custom box
Here is the mould in action
Surprisingly the resin does not flow freely so that it comes level on the air channel side. I guess the part is so small that the resin just grabs onto the side of teh mould and does not flow
