That twist in the spring might be hard to correct. If you grind it on one side, then you have another problem with a gap. Might have to just peen it up and see what you get. Blade looks great. Best wishes. G
Wow ! great job so far
Would heating up the spring a bit and putting it in the vice help or would that just weaken it? Another question, are you going to do anything about that crack in the scale or is it not in danger of getting any worse.
