New Photos and Slideshows

April 10, 2019

After going through a bunch of WordPress slideshow plugins before I finally found a good one, I have started adding new photos of my projects. Eventually, each one will start out with a slideshow of the finished product, followed by whatever build details I have for it. Some of them are quite lengthy.

For this, I built a photo stand that holds each piece at a good angle under the workshop lights. This will make the job of re-photographing everything much faster and easier.

Sandpaper

A subject so simple you hardly even consider it, yet really very mysterious. Just what is the roughness of sandpaper, and the relation to the number on the package?

Here's a plot of some numbers I found online: sandpaper "grit" versus actual micron size. Interesting to see what size scratches you are taking out ( or putting in. ) The curve starts at 320, which is the coarsest grit that might be considered part of the finishing process. For final finishing like orange-peel removal, I start with 1500 and work up from there, I find that even 1000 leaves scratches that are difficult to remove.
