Coming along well on that beautiful piece of tree!
Gotta have some surgery on my neck bones Jan. 6th. Turning my head to look at beautiful women is no longer possible. Also trying to plan a two-week trip to Kenya for March-April. Meeting up with a fellow wildlife biologist, and we'll be working with elephants, rhinos, lions and cheetahs. I'll need to borrow that 4-bore to take care of the charging elephants and rhinos. Don't plan on taking my Service Dog lest she wind up on someone's dinner plate.
Actually, we'll mostly be working with orphaned elephants and rhinos - apparently the mommas and papas are desired by poachers. Something about ivory and aphrodisiac rhino horn...
On that trigger inletting - do you plan to file down the surface that the casting left? That would certainly be a better fit, and it will be easier to color the finished surfaces.
Keep yer chisels sharp 'n' yer brains sharper!
