For years, I've use a paddle as a "whisker pole". Seemed to just have the right length. I knotted a short bungee cord around the handle, that left two hooks with which to snag the clew of the sail. The blade wedged itself on my mast base, and a bit of tension on both jib sheets fixed the arrangement.
I've since built a spinnaker pole from a piece of bamboo (about 1.5" diameter). I just cut it off at the right length and then glued in the fitting using MarineTex (any epoxy paste would do). That worked fine for a season, then the bamboo showed some cracking (from drying out in storage), so I wrapped it with some glass tape and epoxy, and it's still very light and now even stronger.
The length of the pole should be about the length of the foot of your jib. If you want to race your DS, the pole cannot be longer than 74".
If your purpose is to experiment, you'll find bamboo much cheaper than aluminum tube, for the same strength. (That advantage is offset, if you end up giving it a glass sheath, but for a temporary setup to find the best size that works for you, that wouldn't be an issue.)
