All very good points. Thank you!! I was afraid that I was going to have to take them off. I know it's flat, but I didn't think about the pressure issue. I know there's enough epoxy to hold it. It just looks terrible. It's a skeleton tang and all the holes are filled. I even drill small holes in the scales too. Thanks again!There shouldn't be a gap that big to begin with....even leaving a bare spot. So I'd say you didn't use enough clamping pressure (or possibly scale/tang isn't flat).
At this point, you have 3 options.
1. Knock the scales off and re do them. (My personal choice)
2. Leave it and live and learn.
3. Try to fill it. (My last choice. I think filling it will likely make a less than ideal situation worse).
WordI vote for, and strongly advise you follow John's #1 answer. Knock it off and redo. I've been in your shoes, and I suspect we all have..... you don't want to "wreck all that work". But here's the rub.... knowing you CAN do it right, and not, will haunt you in one way or another. Making it "right" will not only give you a nicer knife, it will also give you peace of mind.
Overall, I think you took the best approach. There are so many unknowns when trying to use heat to remove a handle.....that the chances of catastrophic mistake are very real.I had an issue somewhat similar the other day with a hidden tang knife, had to remove the handle and redo it. I ground the blasted thing off, would a heat gun work to release epoxy or is that not enough heat? I was paranoid about ruining my temper so I just hogged it off with a 36 grit belt..... nerve wracking. so I guess what I am asking, what is the best practice to remove a screwed up handle (besides not screwing it up in the first place)
