The process:
Started with hot gluing blocks to keep the sink where I want it.


Next I prepare all the pieces parts to clamp it in place,


To prep the surfaces I sanded the surface with 80 grit block and cleaned up with acetone.


Next was to get the adhesive ready.  Pulled out my old glue gun, purged the adhesive before putting on the mixing tip, then purged it again. No pictures of the adhesive being put on the sink rim,  but I put a small bead on the inside hoping for minimal squeeze out, and a normal bead around the outside, then turned it upside down and put it in place and applied the clamps.

I also ended up sliding some blocks underneath the side to force the top up to the sink better. I think my side boards were only applying most of the pressure to the ends.
Now I wait and see, cross my fingers that the inside won't take much clean up.
Once it's cured I will go on to the front build up. Material is 1/2" thick, so I will add to layers to make the front 1 1/2"

Figuring out how to do something you have never done is what makes a good challenge.
