Using Pine wood for the prototypes I glued an extra pine board to one of the vase blanks. After band sawing this piece from the vase it was then used for the nest of the sanding fixture.
This nest was reduced in size by about 1/8 inch on the sides and top to allow some relief for the sanding (disk & drum) operation then secured to a ½ inch thick hardboard.
The De-Sta-Co toggle clamp firmly holds the vase in place while sanding. The top is rough sanded on a disk sander and the sides are sanded on an oscillating spindle sander.
After rough sanding with 150 grit the sanding drum is changed to a 220 grit drum. For this set up a square is used during clamping to accurately locate the vase onto the nest before clamping for the second drum sanding operation.
The De-Sta-Co brand was chosen because of my past experience with this brand designing fixtures in the machine shop environment. The quality and reliability has never been a problem. The rubber tips take up any minor variation in thickness of the blanks.
