Several things. First an off topic question: Why are your posts showing up in all bold? Not a big deal but it's not normal and it makes it hard to read them for me (and I suspect some others). Are you posting on a net book or smartphone??
Just kidding, but I'm serious about the bold so if you could put a stop to that I think it would be helpful.
Second, forums are notorious for making posts sound harsher than intended. Denster: don't get yer dander up. Your "consider a new hobby" comment is actually well taken but it can come across harsh and his reply was just a man replying to something like that! Give/get. Let's all lighten up please.
To the OP: these guns are notoriously rough machined and their metal notoriously soft. They work just fine, with maintenance, but due to the roughness it can make a complicated tear down even more difficult with parts hanging up etc. Look for opporunities to knock down edges on parts that would have been better finished on a more expensive firearm and read up on how to time and slick them up - it'll be a big help over the long haul. Regarding the dastardly screws, I am no machinist by any stretch but I'm also pretty handy with tools - I know how to avoid buggering a screw, I have a large gunsmith's screw driver set and I'll make a custom blade to fit properly if I need one - yet I STILL have had it happen on these dang Italian stallions from time to time! It's frustrating but part of the learning curve and part of the experience. VTI gun parts has the screws and they're inexpensive but expensive enough with shipping to punish you when you mess up. Just make sure you're not all caffeinated and in a hurry when you work on these things and you'll eventually get it down.
I started with a Pietta 1851 brasser on which the machining was so basic and unpolished that it had edges that would literally draw blood while handling it. I used that gun to learn about how these things work, timed it, slicked it up over time, had to buy a few screws along the way, and eventually had it to where when I'd hand it to someone else their eyes would light up. I sold that gun for a profit and moved on to steel 1860s and Remingtons (which I discovered I like better) and it's been fun. Enjoy the journey!
And by the way, if you'd like one of these things that does not require a lot of messing around with, is easy to clean, and runs like a clock right out of the box - consider a Ruger Old Army! They're sweeeet.
Hang in there.
Cheers,
