I recently bought a window sash set of 1/2" shank router bits. Using the router table, I cut a trial set of 1 3/8" stiles, rails and muntins. The coping bit produced smooth results likely due to the small amount of material removed.
The sticking bit however, produced poor results. It seems an unfortunate byproduct of the router table is inherent vibration. These procedures are normally done on a shaper but I don't have that option.
I'm considering additional trial cuts with the table cabinet loaded with a sandbag. This solution seems rather pedestrian so I'm open to any and all suggestions!

Advice appreciated, Mark
