I like the look of old-fashioned doorknobs with a small rosette. I'm getting some new doors and thinking about boring and mortising them myself. My plan is to find old knobs, rosettes, locksets from eBay and various building salvage stores.
I'm having a hard time finding any info online about how to do this. When I search for "small bore" door materials, I only find results talking about how to update an old, small-bore door to a new 2.5 inch bore hole for modern hardware. In my experience, this sort of issue is usually overcome by knowing the exact terminology used by collectors or vintage enthusiasts.
Can anyone on this forum point me to materials for vintage or period house restoration that talks about prepping doors for smaller, old-fashioned rosettes?
