I use a toaster oven to heat up my knife assembly and speed up the curing process. I place it in the oven that has been pre-set to 120 deg F then "bake" it for 30minutes. Then I remove it from the oven but leave it clamped. While it is still warm the epoxy is still soft and can be gently scraped away from the ricasso area, etc. if necessary. After it has cooled the epoxy will be nearly set. A few minutes later it will be hard and you can continue with drilling, grinding, etc. The heat thins the epoxy and lets it penetrate into the wood and tight corners better. According to Devcon, it increases the strength of their 2 ton epoxy by 20 percent. Most of all, it really speeds up the knife making process. I use Acraglass and it works like a charm. I often cure 2 knives at once and really get to "cookin".
