Bill,, on that buttplate, where the Acraglass was so runny, especially on the vertical surfaces, would it have benefitted you to mix a wee bit of the floxx (white powdery stuff) in with the liquid? Might have assisted in retaining the liquid, and thus less voids between the wood and the metal?
You are doing a fine job on everything. Admire your efforts to make the build as accurately as possible.
That chunk of wood is sure pretty, happy to see you are adding to the strength as much as possible. Ain't simple, throwing a 4-ox chunk of lead out, and being able to take down the target.
Maybe I'll bring you a live baby elephant or rhino to be your pet! 3 GALLONS of milk a few times a day, then 250-400 lb of good hay and grass a day for 65 years!
