Finally came up with a workable solution to guide and hold the vacuum hose on my router. Used a piece of 1/2" EMT conduit with a couple of bends that rests inside a piece of 1" square 1/8" wall tubing. The bottom of the tube is closed off.
The hose hangers were made with 1/2" UHMW and have a 1/4-20 set screw to lock them in place on the EMT. The EMT is free to pivot with the motion of the router movements. So far it is working good with no strain on the “Z” axis.
Ready to start a project !
