I was curious how much of the 1lb jar I should mix up to do a full bedding job on a laminate stock for a savage rifle. I will be grinding out about an 1/8th inch deep of wood everywhere...except where the recoil lug will tough the wood (I will grind out a good deal more so ewill be a solid wall of bedding compound) yes I know I want to have too much than too little mixed but I literally have no idea how much I will need. Will I use most of the jar and should just mix it all? Will I only need half and should save the other half for another job later? I will also be bedding some pillars in but heard this uses very little. Thoughts?
