Designed for a king canada plunging router and 1 inch pipe clamp.
Tighten the pipeclamp over what you need plane and just sled slowly over.
Holes in the bearing cave to help align with the 8mm screw.
Would recommend to glue the screw and nut to ensure that all the bearing stay in place while shaking.
Transversal rods are 12 mm linear guides to fit. Those rod will be just over the pipe without any printed plastic so if by any means one bearing would go avway, it will slide directly rod on pipe to keep stability and not ruin your woodwork.
