I found the pully's at Ace Hardware BTW

Mike, you can make them out of pocket door pully's.

see attached pics of the ones I built.

these are not all of them but it will give you a idea of how to make them.

I found some smaller plastic/teflon ones and then I found some bigger brass ones. They both have somewhat of a sealed bearing and the brass ones I used for the anchor rope pully's I mounted in the floor to redirect the rope around the seat instead of having the rope and cleat between my feet etc.

Hey Mike, Im sure if you emailed Jason he would tell you where to get the pullys. He has answered my emails regarding latches from SouthCo and some other technical questions.

I am building the Freestone guide but I have modified everything. Its actually going to be more like a smaller Kingfisher Recurve. I think most hardware stores would carry a variety of pullys and Im pretty sure most quality ones would work. Thats what I plan to do when I make the anchor arm. Im modeling the dierks anchor arm made from wood and pullys, then Im running the tube underneath the floors and pedestals where the rope will meet up with a simple pinch cleat rather than the floor pedal.
