I have a Nording pipe that has been causing me some headaches recently. Sorry if I use improper terms to explain the parts of the pipe but I'll do my best. Hopefully someone can help me out as long as I get the pictures posted right. It seems that when the draft hole was drilled, it wasn't exactly in line with the mortise. The pipe does not pass a cleaner while assembled. I've seen this to an extent on a few of my other pipes but not to this extreme. I can even pass a cleaner through this hole into the bottom of the mortise while the stem is in place. The problem I have with it is that when I draw on the pipe I'm actually drawing as much or more air through this hole than through the bowl. I find that when I plug the hole with a pipe cleaner/ my finger the pipe smokes perfectly. My question is what could I use to plug the hole with? I was thinking some kind of wood filler or putty. Any help would be greatly appreciated. Thanks.
