I've been experimenting with spray finishing and joint finishing. The bad news is that trimming up case joinery still sucks. I have to plane end grain immediately surrounding by face grain. And I have to do it without gouging up the face grain or blowing out the grain at the end of the board. So far I suck at it. I need to prevent corners from gouging, and the blade from chattering.
The normal tool for doing these end-grain trimming is a block plane. Unfortunately block planes don't usually have heavy blades, and because it's a bevel-up plane, there's no chip breaker to stiffen the blade. So I'm going to have to build a lot of casework corners (read dovetails, because they're the fastest to cut). I need to try some different blade geometry. I have a Japanese smoothing plane, which is only slightly larger than a block plane, but has a blade about three times as thick, and a slightly curved edge. It's also easier to secure work for use with a Japanese plane, because it works by pulling the plane toward you.
The good news was in my spray finishing. I messed up my flow rate on the first pass with the stain, but after I sanded that out, spray toner (stain and finish mixed) gave a really nice look. I was able to spray a single layer of clear coat as well, and found it to be exceedingly nice. I wish my surface prep underneath it had been up to the quality of the finish.
