Lock Timing

Our lock timing and photography project is finished. My son, Kevin, arrived from Denver on Thursday night. We began Friday morning working the bugs out of our equipment. Our goal was to time the shooters’ locks and take photos showing the spark production and where the sparks landed. Along with the photo, the owner got a paper copy of the lock times we recorded. The software allowed timing to the nearest 10 ... Read More »

BlackPowderMag’s next project will be at the NMLRA Spring Shoot in June. I have received permission to time and photograph locks in Booth 112. Some of the details remain to be worked out, but I hope to be set up and working Saturday, Sunday, and Monday. I plan to time a shooter’s lock for 10 trials and find the average. A photograph will be taken of the lock making sparks. We want ... Read More »

I’d like to thank Gary Brumfield for his encouragement and advice during the data collecting and writing of this article. The Siler below is the lock used in the ’80s for the JHAT article. It has been fired probably thousands of times, but never was mounted on a gun. The article below listed all the modifications that were done when the lock was made. It has served as a test bed for ... Read More »

During the past two years I have had the opportunity to measure the ignition time on a number of different flintlocks. The locks varied from superb original locks to modern day reproduction locks. Some were in mint condition, while others were somewhat used. The equipment that I use to time locks consists of a computer and interface made to scientifically measure time in a high school or college physics lab. It has ... Read More »

Most of the testing and timing of flintlocks completed at this time has been done with modern reproduction locks. Because of their value, original locks should not be subjected to an extensive number of tests. Lock makers of today can’t help wondering how their work compares with the work done during the flint era. The Journal of Historic Armsmaking Technology Vol. IV has attempted to shed some light on this subject. The ... Read More »

Most of us, at one time or another, have wondered what factors cause locks to produce good results. Obviously, there are considerations which we have not been able to measure and maybe can never isolate. In this article, I would like to look at some factors   Photo 1: The flint is just about to begin contact with the frizzen. Two thirds of the mechanical time is complete. which have not yet ...
