D.I.Y. Ring Kit

[dlang]

remember that the forces on the rollers are very small, take a look at this post
(from the 755 post thread where the triangulation kits were developed, the
entire thread is worth reading)

Throwing my hat in the sled modification ring

I have some thoughts regarding the use of (roller) bearings as pivot points in the linkage design. I have put a lot of thought into the forces involved and I hypothesize that greatly reducing friction in any of the pivot points of the linkage design is not necessary to achieve smooth motion and accurate cuts. I know that sounds ludicrous but please bear with me First, picture the beautiful ring and roller idea that @bar presented in the first post on this thread. In order to achieve smo…
