Last night, after about 48 hours of cure time, I went out and checked my glue-up.

Some areas were still a little bit tacky.

The temperature here has been in the 40s at night, though, and in the 70s during the day (Farenheit).

Time to rip everything out, or should I give it a few more days?

What I did different this time was make two smaller batches so as to not waste as much. It took just a small dab of hardener. But I have been thinking that may not be a good idea. Over on the resurrected Canard Forum there was a thread about saving money by not wasting epoxy. The problem I see with smaller batches, and what may be my problem with this glue-up, is that any measurement/dispensing errors would be a higher percentage of the total batch. I know it is wasteful, but I think I would rather throw away some epoxy than have a joint failure at 5000 feet!

My first glue-up has turned out fine, by the way.
