I was just thinking that gluing in strips of veneer would work, but it would be next to impossible to get the perfect thickness to begin with. You would need to glue in over-sized pieces, and then work down the dimensions to fit the barrel, and be in line with the key and breech, etc. Transfer medium will be of little help, since the barrel-to-wood fit will already be correct (theoretically), the barrel will just sit too high. For me anyway, it would be a real pain in the you-know-what to scrape out a consistant smidgeon of wood, from a blind starting point.
I think with the glass bedding, you could do it in two sessions, with a little forethought, and just be done with it, especially if the gun is a production model like T/C, CVA, etc. Now, I high dollar custom rifle is another matter. But I don't think that's what we're talking about here.
Just thinking out loud guys :wink: . Bill
