Never thought of Accra-glass.
I just use "Gorilla Glue" for most any wood repair, now, especially pieces that are difficult to clamp. You get the best bond by wetting both surfaces, glue, and hold together for 1-2 minutes. If there's nothing pushing the pieces apart, you can get away without clamping, but clamp it if possible. Also, even if you don't get any "squeeze out" initially, you will as it expands as it hardens. But any excess is easily scraped/sanded off.
