Power Twist Belting

[Greg Lambier]

i used 3/8” diameter polyurethane belting on my rose lathe. It is proving to be pretty springy and a limitation on which rosette’s can be used. I see David Lindow used v-belt in later lathes for this reason. However, switching to v-belt pulleys and idlers creates a lot of work and some challenges. It was interesting making the index wheel and all of the pulleys with a round profile the first time. I see that there is a ground round 3/8 twist lock belt that Fenner supplies as a replacement for round polyurethane to address some of these issues. I am wondering if anyone has experience with it in this application and can advise on their experience. For example does it stretch enough to roll onto the pulley’s?

thank you,

Greg

Greg, there is. I recommend you contact David Lindow or Wes Pilley.

FYI, So I have tried the 3/8 round power twist belting and it works better for me than the polyurethane belting. I don’t believe I had enough tension on the polyurethane belting so that may have contributed to some of the issue as well. I had some issue with power twist trying to climb out of my 3/8” half round profile pulley’s but resolved that by modifying the profile to be a little deeper/wider.
