I finished my first rod a few weeks ago and I really enjoyed the build process. My son is moving to Colorado this summmer and I plan to make him one before he leaves. Anyway, I made my own wrapping gismo and I use the rotisserie motor from my BBQ grill as the drying motor. It rotates about 6 RPMs. If you have basic woodworking tools/skills you can make your own. Look it up on YouTube and Google instructions.
