Thanks guys, I'm in central Florida and the weather until day before yesterday was dry and warm. It rained all day on Monday and stayed cool. Since then it's warm and steamy.
I re-taped last night, this morning the left over resin in the cup was hard as a brick bat and the joints were dry to the touch but still a little soft that's after 12 hours. I think it's a good sign that the cup hardened, I know the joint will take a bit longer.
Maybe my pumps are off since I used the measured cups with what seems (fingers crossed) to be a better outcome.
I bought the epoxy and pumps from B&B so I don't know the brand. The batches two batches that did cure when I started were crystal clear and looked really nice.
By the way hokey I used two 3/4" battens screwed together through the seem between the bottom and side, worked like a champ. Thanks for the suggestion.
