I've built a number of rods, some of which I am very proud of and others are......functional. 

My question is about wrapping the guides closest to the tip.  In order to get the last one or two lined up with my tension arm, the blank's tip is left unsupported. What's the best way to overcome this?  I've been using a thread bobbin to do them, but I question the uniformity of the tension on the wraps.

I just put a support as close as I can and adjust tension. You can tape a small dowel to the tip to reach the second support. 

Thanks Mike. I figured everyone has their own way of doing it and there is more advanced equipment that incorporates something for the task.  I'm just looking for something more uniform that what I've been doing.  I'd even considered placing my old wrapper in front of the new one and running the thread from the new one through its guide. That is what I'll be trying with my current build.

I use a Rite fly tying bobbin for most of my tips.

I don’t even put a wrap in the tip top anymore, it was just decorative anyways. Just a little bit of finish on the rod extending to the tip,  serves to the same effect. 

Try doing a noodle ice rod.  It makes anything else seem like a breeze.
