I have an 8' 6" blank that I want to make 10' 6", How much or how far do you want the extension to go inside the blank? The reel seat is going to be half way on both sections, the joint will be in the middle of the reel seat.

I've removed the pistol grip and added a 7 -10 in. rear grip with an extended section of scrap blank 2 to 3 in. inside of the blank the length of the new grip on more than a dozen rods. There are no returns yet. IMO 3 in. should be enough to insure a secure bond with this long a rod with the join under the reelseat. Make sure the tapers match or wrap the insert to get a good fit. I'd let the join cure overnight with Rod Bond before further assembly.

If at first you don't succeed, go fishing, then try, try again.

The extension should go on the outside of the blank. RodMaker Volume 6 #3 has a complete article on extending rod blanks with all the specifics involved.

In the meantime, you're talking about extending a blank by a full 2 feet. I would build the entire handle section on the extension piece (heavy wall blank or aluminum tube) and then insert the butt into the extension by a distance that is equal to about 5 times the diameter at that point.

Tom you state "The extension should go on the outside of the blank. " is there a reason for this?

Structural integrity, you should listen to Tom on this he is 100% correct
Look at any flipping stick type rod that extends out and with out exception. The butt section is on the out side. If the manufactures of these blanks could get away with less material by putting it on the inside they would, but they also understand structural integrity.

Yes, the larger diameter creates a stronger piece and better continuity of action. A smaller piece will have to be much thicker in the walls to be as strong as the piece you're putting it into. I'm not saying it won't work, but it's not the very best way to go about what you're wanting to do in this instance.
