So I'm working on a CS frontier hawk. I've been working on the fit by continually sanding down the marks after pounding it on, getting a lot tighter but taking some time. Anyway when I get the fight right I was gonna rub down the handle with linseed oil, I heard that soaking the head & top of the handle in a bucket of it for a day or 2 will swell the wood and make the fit much tighter. Anyone have experience with this? If it works about how long does the effect last?
