Tor Thank you for your offer and will keep it all in mind...Andrew I have only messed with this machine about an hour or so..I did get it working pretty well ,but feel I just need to fine tune it when I get a little more time.Yes it only has a bottom roller but it will eat anything that you feed it when it is set up properly.My buddy runs 12oz bridle and harness that is sometimes very dry..We primarily work with 12 oz latigo and thinner...
