Ben,
Not looking for any secrets, so "that's my secret" is a perfectly fine answer ---
but, I am literally blown away at the wood to metal fit. I have not much of an
idea how it would be possible to get that perfect a fit. It is just amazing to look
at, certainly an A+ in my opinion.
Is there a "25 words or less" sort of explanation of the process? Is it just fitting and
scraping with some sort of marking material like soot or lipstick? I entirely understand
that, having scraped Babbitt bearings in an auto engine, so I do undersand what sort
of dimensions can be held with that process (Prussian blue and triangular file-type
scaper), but it doesn't seem applicable to wood and metal, fitted on all sides.
