Improved drill stop collar for Edge Pro
Posted: Wed Sep 12, 2018 6:51 am
I just want to share a gizmo I made that is an improvement over the drill stop collar used for the edge pro professional for catering for the differences in stone thicknesses.
The problem with a drill stop collar is that it doesn't cater for stone thickness perfectly. There is actually an error due to the differences between the angle of the vertical support shaft (between the bench and the stone rod) and the perpendicular to knife/stone angle (I can't think of a better way to word this).
That is, ideally, you'd want to offset for the thickness of the stone along the same axis perpendicular to the knife/stone angle. The drill stop collar only offsets along the shaft which is usually not be the same as the perpendicular to the knife/stone angle.
I've attached some pictures of the gizmo I created which offset the stone thickness properly.
I used a 3d printer to print two block separated by a square rod, fixed by thumb screws. The top block has hole for the stone rod. The bottom block is attached to the original vertical support shaft block.
Before swapping out any stones, I make sure I sized the distance between the blocks by loosening the top block, putting the stone between them, and then tightening top block again using the thumb screws.
I made this for my edge pro professional, but I don't see why the same design can't be used for the edgo pro apex.
