Okay... a little putzing around in the garage last night and I made a servicable prototype rod holder.

I used
• two wooden dowels (sharpened at one end to add a danger factor!)
• a small piece of 1" thinwalled PVC pipe
• a piece of scrap steel
• zip ties
• electrical tape
• spraypaint*
• "rubber band" made of old innertube
*although this is optional, with how shoddily constructed this thing is it probably helps hold everything together!

Below are some pictures. Let me know if you have any questions.
