I know a little and have "built" and fixed many a revolver over the years but a few years ago my dear friend gifted me a 14 that someone had tried to make a "competition" piece out of... it's like they had the concept but their execution was poor. They made it a DAO and did some weird stuff.
I had a bunch of new old stock internals and wanted to make this my son's gun, one he could learn to shoot and load up with wad cutters and go to the range with me. Dealing with brand new pieces I really learned a lot over the next few days, I really learned what part does what and why, take a little off of here to make this fit and go better. I ended up with a few sleepless nights and the journey was much more than I had planned. It was much more than dropping a used fitted hammer, trigger or hand in... I learned a TON about a sear those nights.
Came out excellent, best action I have ever felt and shoots like a dream.. wish you the best in your journey. That looks like a really neat "kit" you have there. I think you're about to have alot of fun.
By the way, I have never owned a "wrench" good piece of leather, a good vise and a hammer handle have changed out a many a barrel.
After you accomplish that, you'll be on your way.
Now I kind of look for a good project piece of priced right. I also enjoy rebluing an old tired one and even done a few nickel with some assistance.
After that one if you think you have them mastered, get you a colt and try! They're a whole bunch of fun! Especially an older Python! I used to cringe when taking one to my local expert gunsmith. Now if I take him something I think "heck that's cheap, he ain't charging enough for all the time involved with that thing".
