Want cut a foot off the butt of a blank I dont believe it willchange the action.But is it true that if you have a 2 piece blank the tip has to longer than the butt? If it is true what is the reason for it? I think that this question brings me up to 1,000,000 . I want to thank everyone on this board for being so patient and informative.I've learned a LOT.Sorry its probably in the search but I could not find it.

I was told that is was to have the heavier butt section protecting the more delicate tip section. It makes sense, but it may not be true, so don't laugh to hard at my expense if I am wrong :)

WRONG! is my middle name.

It will change the action - the action will become slower.

It is common to see two-piece rods with sections that are not equal in length. Many surf rods utilize off-set ferrules with very short butt sections and much longer tip sections.

The thing about "protection" for the tip has to do with storing the pieces, unassembled in a bag or tube. It's thought by some that by having the butt section a bit longer than the tip that any damage that could be done to the tip will be checked by the slightly longer butt section.

Tom ,sorry I don't understand. The butt being stiff and virtually inflexible can't figure out how this would affect the action, not unless it has to do with the reduction of the length? Why slower, the shorter the blank the faster the action most of the time? Don't understand off set ferrules are they off center? Why?

I would think for the protection of the tip and furrule, you might be better off finding a blank a foot shorter

I think it's in regard to the ferrule ,in relation to the length of the blank.

Bill,

As for the action, Like Tom said, it will be slower. Action is determined by the flex point of a rod A fast flexes in the top 1/3, Mod in the middle 1/3 Slow bottom 1/3. Take a 6' blank for example say that it flexes 2' from the tip if you cut a foot off the butt it will still flex 2' from the tip but the flex point will now be a foot closer to the butt making it more moderate. On the other hand, if you extend the blank 1', the flex point will be further from the butt, making it faster Hope this makes sense

by adding/removing from the butt, you can "tweak" a blank to get a preferred action (up to a point)

I knew about the action, but never thought of it in regard to the length of the rod. Hope this makes sense. Thank you

Mike summed it up pretty well. Whatever percentage of the blank the initial flex takes place in will increase when you shorten it.

You can also rig up a CCS test and by slipping the butt of the blank back through the support point you can tell exactly how much the action will change in terms of actual numbers. Or, you can hold the blank by the butt and press it on the floor or ceiling, then shift your hand up to where you're going to cut it and do it again. You'll at least be able to see the difference.

Off set ferrule?

When the ferrule is somewhere other than in the middle of the rod, it's generally referred to as an "offset ferrule."

.........

Many heaver type surf rods are made this way. Short butt, longer tip.

But why off center for the ferrule?

The key word is "Offset" not "Off center" The ferrule is centered, it is just not at the halfway point on the blank On a 2 pc rod, If it is located above or below the halfway point on the blank, it is often referred to as "off set"

Mike

BC - A rod ferrule that is placed closer to the rod butt than it is close to the rod tip (below the half-way or midpoint) will be in a stiffer section of the rod blank for most rod tapers (actions). This will usually mean that the ferrule has less effect on the rod's overall feel, because that section of the rod blank isn't flexing that much anyway. So the type of ferrule (tip-over-butt, or plug-spigot or even metal) has less effect on the rod's flexion simply by being in that lower or "offset" position. Since the forward section of the rod blank is continuous, there is now no ferrule there to alter the rod's flexion. Well-designed ferrules (plug-spigot or tip-over-butt) will flex with the rod, and be strong, too, without having a noticeable effect on rod performance or adding too much weight. ...

Table of Effects of TRIMMING or EXTENDING a ROD BLANK on its Various Performance Properties "Table of Effects of TRIMMING or EXTENDING a ROD BLANK" [www.rodbuilding.org]

If you want a SHORTER version of the rod, with nearly the same action, trim from the BUTT.
If you want a STIFFER version of the rod, with a stouter tip, trim carefully / successively from the TIP.
If you want a LONGER version of the rod, with a very similar action, EXTEND from the BUTT.
The most dramatic alteration of a rod blank's properties would come from trimming its tip. Trimming or extending the rod blank from the butt end has a less pronounced effect on the rod blank's performance, with respect to the forward-tip's action-taper. -Cliff Hall, Gainesville, FL-USA+++

Thanks Cliff that's what Im looking for. Never saw that info on rodbuilders search.
