I was playing around last night with making my Rostock to use the full length of the smooth rods even though my belts where not long enough. I didn’t want to mess with the spindles used for the Spectra line mechanism.
I came up with a hybrid. It uses the belts for the drive side, and the fishing line on the idler side. I also am using a zip-tie tensioner.
Doing things this way, we only need belts as long as our smooth rods.
It’s not running yet, as I am waiting on my pololus. But it looks like it should work out.
