The first wait begins.

Funny how I put off starting this project for months, and now that I HAVE to wait, it's killing me. However, those who know, advise to allow the epoxy to cure at least 24 hrs... preferably longer. So I guess Saturday will be the day. This pic was taken Thursday. The blocks tended to "slide" on the layer of glue, so I kept checking on alignment for about 30 minutes. Once satisfied that they had 'settled', I put out the lights and left them to cure.
