trace buttplate on stock.
bandsaw to within 1/4" or so.
1.5" sanding drum on cordless drill (80 or 100 grit) - this does most of my rough to almost finished fitting.
keep it moving in nice smooth arcs up and down the curve.
life got easier once I started using this technique.
finish fit with chisels and gouges, with or across the grain.
LOTS of transfer medium near the endstage.(I'm a lipstick dude
)
I like to leave the hump under the buttplate tang/return - don't know if that's how most do it or not.
cool tip about wetting the end grain and using scraper, Ken, thanks!. will try that.
