Cresting Jig Base is made of Fir, Pine, Redwood and may include other decorative woods. The runners are made of Tempered Bamboo and the slider is made of Maple . Wood parts are finished in clear gloss. The slider allows the support of the shaft very near the work area which helps minimize wobble.

5 ft cord. Base is 23" long and gives about 18" of working space/length. Can be used with bare shafts or fletched arrows, with or without nocks. Can be used with wood, carbon, and aluminum arrows. Now with improved arrow chuck to hold your arrow even more securely.

I don't know the exact RPM, but I've been using one of the same design for years. Works great!

2 speeds. They are very close in speed, but there are two settings.
