Good Morning,
Those links are to my web site. My son and I started it in 2006 to post past experiments and to publish new ones as they were done. The first link is to high speed stuff I did in my garage with the help of the regional rep from Olympus. The last link is video from Gun Makers' Hall at Friendship. The man holding the locks is ALR's own David Price. David primed and handled the locks while I burned CDs for the lock owners. David was a great help. We videoed over 30 that day; without David's help it would have pushed us to do half that many.
Other things on the web site that might be of interest are articles on timing priming powder, vent location, and locks. There are also high speed still photos of patches separating from the ball and spark studies comparing lead vs leather as the method of holding. (Basically a mix of "flintlocks and science" when I could get them close enough to combine two passions.)
Regards,
Pletch
