i think Tindo used brass hunges. maybe a PM to him could get you the info you need. i thought i remembered him using silicone though.
what kind if silicone did you try?
i use acrylic hinges even on glass doors. ive been using a 2 part epoxy from loc tite, and ive used silicone. i like the acrylic hinges because you can see through them. i havent found the totally clear epoxy yet, but a friend of mine is using a devcon brand that im yet to find locally.
heres a link to his conversion kits. he sells them with an acrylic piano hinge thats epoxied on. you can see how clear it comes out if you look at the bigger pic of the 10. i use the 2 1/2" hinges, but plan on trying out the piano hinge soon.
