Thank you Herman, found it. It was back in 2002 A bit long, here it is. Del asked , "How do you find the spine." Here are two messages I posted on a Bamboo Rodmakers list that I am on. Hope this helps. Tony [EMAIL PROTECTED]
Subject: Spine spline Subject: Re: The Spine in the Splines Date: Fri, 09 Feb 2001 16:05:24 -0600 From: Tony Spezio <[EMAIL PROTECTED]> There are several ways to find the spine. I will only cover two ways here. I put the butt end of the tip section on a flat surface with one hand pressing down in about the middle of the section. The other hand at the tip so that the tip top can roll in the palm of your hand. Press down to bow the section while you roll the section till you feel a jump. That is the spine. Roll the section till it bows without any resistance, the guides should be on the inside or outside of the bow. (curve) The guides should be lined up with the bow and not off 90* or so. This is loading the rod. You will find if the Spine is off, say 90*, while a load like playing a fish, the rod will want to twist in you hand to the soft side of the rod. In casting, the line will want to cast off center. Harry mentioned something the other day about checking the spine on a table. If you lay a blank flat on a table with about 2/3 of the tip section off the end and bend the tip and release it. If the tip is not on the spine it will oscillate in an oval. The closer to the spine the narrower the oval. When on the spine it should just vibrate up and down in a straight plane. Doing this will give you an idea of what your line will be doing when you cast a rod that does not have the guides on one or the other side of the spine. (soft or stiff) I do know books call it a spline and it may be, but to me it is the spine I am looking for. I have made three G------- rods with the guides on the outside bend, did not like them at all. Made over 100 with the guides on the inside of the bend. I find that the guides on the inside seem to cast best for me. The tradition I have heard is: for power put the guides on the stiff side, for accuracy put the guides on the soft side. I go with the soft side except for Casting and Saltwater rods. Yes, there can be more than one spine but one will always be pronounced . That is the one I use. I have had two bamboo blanks that it was almost impossible to find a spine. Can't tell you why, don't know. I make them all the same way. Now to crawl back into my hole. Tony [EMAIL PROTECTED] After I posted my message I got several off list messages as to why I place my guides on the inside of the curve. Rather than answer them separately I will post my reply. I may be all wet but this is my way of thinking. Think of your rod as a bow. With the guides on the soft ( inside) side when raising the rod to pick up line off the water the line puts load on the rod. It will bend and load the rod on the soft side, (inside bend) more than it would on the stiff side. As the rod comes up and the line loads the rod on the back cast it has resistance from the stiff side. It will want come back to neutral. Being that the rod is loaded on the stiff side now, it will want to straighten out fast and will throw the line out with higher speed. Being that it has to work against itself in the opposite direction it will not bend as far forward as it does back thus keeps from throwing the line down. It will tend to stop quicker and throw the line straight out instead of down. In fighting the fish, The rod can be raised higher and the fish is fighting the soft side, this is easier on the tippet and more pressure can be put on the tippet without it breaking due to working on the soft side. What happens when you have no spine, darned if I know.
