</FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=2 FAMILY="SANSSERIF" FACE="Arial" LANG="0"> The joint under discussion is replacing the butt joint between the panel edges with a tongue and groove joint. If you follow that then think about cutting this long boardVERY,TOTALLY straight joint on some piece of machinery. Each board must be cut Totally straight on both its edges and yes so there are no gaps between. Also this is an advantage as Ron O said that thinner thicknesses of spruce can be joined thereby saving material. With grade A spruce at $8 to $10 a board foot (and the average panel requireing 25 bd. ft of material) any screw ups are going to add up in a hurry.<BR>
Hope that helps . I have trouble following my own train of thought too.<BR>

Dale, <BR>
Could you expand your thought a little here? I don't really understand what you are saying. Specifically what do you mean by "making a straight line over large lengths of wood". Are you talking about gaps in joining boards? I'm afraid I'm not following your train of thought. <BR>

</FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=2 FAMILY="SANSSERIF" FACE="Arial" LANG="0"> I thought that tongue and groove might be a good idea long before I heard about it here. Lately I've been day dreaming about finger joints. Any feelings on how that might work in a soundboard situation? It seems that a finger joint would offer more surface area than a tongue and groove. Call me a ponderer.</FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=3 FAMILY="SANSSERIF" FACE="Arial" LANG="0"> <BR>

Greg -Finger joints will not work. Even the tongue and groove joints must be positioned towards the bottom side of the panel so that they are not exposed while diaphramizing.</FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=3 FAMILY="SANSSERIF" FACE="Arial" LANG="0"> <BR>
