Doug, thanks for the PBS Banquet donation!
Here are a couple of quotes from Jim's brochure: "I have been making, and selling wood arrow shafting since 1985. I now specialize in Tapered Port Orford Cedar shafts, and arrows."
Also:
"I do all of my own tapering, and have experimented with various configurations. Overall, I feel that the single taper is the bowhunter's best bet!"
Jim's business is called: Custom Tapered Arrows and Shafts and the address is: 15563 Co. 27 Blvd. Pine Island, MN 55963
