Last year at the Bowling Green NMLRA Gunbuilding Workshop I had the good fortune to be in Mark's class. We arrived with a blank and its .58 cal. barrel inlet. Under Mark's instructions we inlet the breech plug while it was attached to the barrel. We drilled the ramrod groove and shaped it with Tom's fine groove plane. We shaped the stock with a gouge, a scrub plane, spoke shave and box plane. We only used wood rasps where the planes couldn't go. We set the buttplate. I regret that I had to leave two days before the class concluded because Mark also taught his procedure for inletting the lock without disassembly. (Well actually, I was a bit relieved I didn't have to do that job on the rifle I was building.) Mark's class was a great learning experience.
There were only eight builders in the class...all quite capable builders. I remember a moment when I looked up from by bench and Mark was perched on is stool pointing out to one builder where his rifle needed more attention. Mark was wearing his work apron and had his eyeglasses on the top of his head. It was a time warp. I realized that that very scene would have looked exactly the same in Schroyer's, or Beck's, or Verner's shop.
If you are thinking about signing up for Bowling Green...do it. Mark is teaching again (bless him), but he is only one of the world class instructors who teach there.
