Thanks for your your kind words, everybody. It has been a fun and exciting journey for me to say the least! I hope it encourages or inspires someone to building a gun.
Oldtraveler, I don't believe the barrel ever gets hot enough to harm or weaken the steel, and I haven't experienced any problems with the last barrel I did. Jack Brooks thinks that it charcoal bluing will anneal the barrel, I assume because it may relieve stresses in the metal? I am no metallurgist, so my opinion and 50 cents will get you a cup of cheap coffee!
Snapper, I hope to see you there in Friendship and shoot the CS rifles together as well. Let's both bring an extra gun so TOF can participate after his gun refuses to fire.
Ed & Norm, I plan on bringing it to WKU, see y'all there!
