Let's see what the prototypes look like and how they perform. We chose teflon because of its ability to handle temperatures up to 500 degrees. Delrin is good to 185 degrees. We were unsure what temperature the rope may get to as it slid across the rollers. The teflon costs $22.25 per foot, delrin is $5.50 per foot. If a combination of the slippery roller and the slippery rope won't allow the winching rope to turn the roller then the teflon was a good choice. If the rollers turn, maybe the next batch should be made out of delrin. I'll let you know as soon as we spool up the rope.
