Manipulating 6" PVC conduit is a challenge ! Making the transition
from 4" to 6" involves more muscle, but the mechanics are the same.
Why Cantex ?
Why Cantex ?
Their material is UV-stabilized for weathering strength in the changing climate of Northern Ohio. It also machines and drills consistently. The dielectric constant is the same from piece to piece, and the Cantex compound resists bending. I've filled a dumpster with look-alike parts that failed to survive the coiling process at some point.

Let's wind some coil !
The operator guides the wire on to the rolling tube. The wire spacing is determined by the guide tool. As the wire is fed, the operator holds the tool against the tube; the wall thickness of the guide is the distance between the turns. The guide rubs against the adjacent turn and is pushed to the left by the pitch of the wire. Clear enough ?? Some form of automation is called for here. Wind-time for a 10' section at 190"/minute surface travel speed is about one hour and forty five minutes. Please note the use of loose-fitting gloves.
