Today I saw a Porter Cable Pin Nailer. It uses 23 gauge brads 1/2 inch to 1 inch. I have brad nailer and stapler which I used lot in making wood buildings. But the gauge of the brads is some what big. I looked at the 23 gauge brads and they looked small enough for tacking corner trim and roof facia trim. Might even work in reiforcing the joints in wood frame rolling stock. Has anyone used one of these?
