I'm currently renovating my house and my first project is the doors. I've got some panel doors with very small edges, and I want to keep these edges nice and sharp.
I've put my paint skills to use and made a cross section (not to scale) of the (trim?) of my door. The red corners I want to keep sharp but it's quite easy to accidentally round them and the green corners are difficult to reach.
I can manage quite well by hand but I've got 11 doors like this and am thus looking for tools which will make my life easier. I have got a rotary tool and was looking at sanding cones:
However these are not readily available in the Netherlands nor do i know if it is the best attribute to use.
Some advice as how to best sand this would be appreciated.
Please note that I want to stay clear of chemical removers because scraping away the paint from this seems like a rather tricky thing. So I am mainly looking for sanding tricks which won't wear me out. However, if there is no better way I'll have to try it out.
