This advice is all much appreciated.
I have pretty much ditched the idea of an ash stock While the stated difficulty working with it is a concern, it is also true that, having to buy a blank and have the stock carved and barrel inlet would add about $200 to the gun. Frankly I don't want an ash stock that badly. My .50 is stocked in curly maple, my .54 Walnut so I'm thinking cherry. I'd like a different wood than what I have, but I'm always open to suggestion.
I figure to have the barrel channel cut/ramrod hole drilled for me.
Barrel came today, the "Brown Truck of Happiness" rolled in here about 2PM.
Stock is next.
