Thank you @road2horizon. Restoration is not my hoby. But i were a sculptor before and these kind of jobs familiar to me. Because of this i can say this is not first time for me but i can say i made a post about it for the first time. I do not have atelier because of this i can not do these kind of things regular. But i made some plexiglass rings and prepared their presantations like this one (Step by step) If you interest about these kimd of things check my blog please.

Thanks for interest
