Ditto to what Ranger said. Anyway, Builder, do you mean you put the cut straw between the bucking and the barrel to make the outside surface of the j-hop smooth? Another way you could do it is by leaving the outside uneven and just glop it on, take a razor blade and chop it down when dry, then sand it smooth. You way is probably easier though lol. My problem is I always get air bubbles on the inside the barrel side so the contact area isn't perfectly smooth. I'll try thinning it with mineral spirits if I ever get around to it.
