Again, you can't see it but where those are joined together, the acrylic solvent is crystal clear. It is a bond that is better than the actual material. It is more of a weld and less of a glue. In fact it isn't even glue at all. Just solvent. I did the bolts (1/4 x 20 x 1 1/2") because i wanted them in there but at this rate, they don't really need to be there. It was nice to suck the pieces together with them though instead of a clamp. This thing should look nutty when fully peeled!
Look real close...the seam is welded. It is one. And it came out clean! especially for a huge 1" slab. It is EASY to completely ruin this so i am happy it is going well so far.
