This is a great thread for those of us who wish to admit their mortality.
I've built a lot of rifles, cut my own barrel channels and drilled my own ramrod holes on most of them, all without a single problem - almost! For my own personal Hawken build, I acquired a piece of the hardest maple God has produced to date, from Tom Curran in NY State. It was so heavy that I thought it must not be dry, so I checked the SG with my meter and it showed ~ 10%. Still thinking the wood would lose more moisture, I set it aside for several more months, weighing it every month end, and it didn't lose any weight. So I inlet the barrel, tang and breech, triggers, lock, etc and shaped the stock. When I drill rod holes in half stocked rifles, I use the barrel pipes on the under-rib to guide the drill, in this case, a 1/2" brad point drill that I've used successfully many times. With everything set up perfectly, I started the bit into the end grain maple...I was amazed at how hard drilling it was. No problem, just lean on the drill a little harder - right? About two inches from home, I discovered the bit working it's way through the off side of the forestock just ahead of the lock panel. Naturally I stopped drilling, and assessed my predicament. As you might imagine, the temperature in the shop went to boiling, and the air was blue from the conversation I was having with myself. So I carefully used chisels and scrapers at the entrance hole to move the drill in the direction I needed it to go, and started over. Within minutes I drilled through the bottom of the stock only inches behind the entry pipe area. I said, hmmmmmmm!
This time, I left the shop for several hours while I attempted to calm down. Finally, I decided I didn't want to waste the stock - special from Tom, beautiful wood, etc., so I took a 1/2" hickory ramrod, slathered it with wood glue, and slid it into the hole. When it had cured, I cut off the hickory, flattened the end where the drill must start, and set up my 1/2" TRACK OF THE WOLF RAMROD HOLE DRILL, and started over. This drilling went smoothly and easily, and the bit stayed right down the centre of the forestock, ending directly under the forward extension of the trigger plate, just as it was supposed to the first time. Now I had two holes to plug, so I took wood that I'd cut from the stock during the bandsawing phase and checked grain and figure orientation, cutting two plugs with rounded ends. I inlet these plugs into the holes I'd created, and finished the rifle like normal. This rifle is a personal piece and I have no intention of selling it, so I get to live with these glaring mistakes for the rest of my life.
I learned my lesson and admit that I'm a mere mortal. I have my feet set firmly on the ground. I do love the rifle though, just the same.
