Because I have never been one to go quietly and I have mentioned on more than one occasion “what can’t speak can’t lie” I thought I would put some money where my mouth is and add some pictures of my saddle. Not quite perfect but I am still perfecting the technique.
All the work on this has been done with a rotary tool.
For the sake of the pictures I added more Prussian blue pure dry pigment and thinners so I could get a very thin coat on the inspection grade surface plate. The saddle was slid approximately 6mm (1/4”) vertically and horizontally with no down pressure and the pictures were taken in day light with no flash. There is a little glare from the sun which was quite low at 6.00 p.m.
When I have perfected the technique I will post updates if needed but the 9000 rpm of my rotary tool is to fast and about 1000-2000 rpm is better. The bobbin is approximately 15mm in diameter and I have switched from the standard wood sanding belts to wet and dry belts ranging between 250- 600 grit used dry.

EDIT: I have added a picture of the saddle before scraping.
