You sound a lot like me, I've also got an ME degree and love the machine we call a gun. I've been tinkering with them for a long time. The Fusion stuff actually requires little fitting but then also doesn't have the precision custom fit you'd expect from a top end gun. A good example is the frame to slide fit which is loose on my gun when compared to a Wilson or even a Kimber but reasonably tighter than my stock Colt running clearances. I can't outshoot this gun, so whatever minor variations in point of aim vs point of impact are caused by a looser running slide I can't seem to find. The barrel to slide lock-up was hand fit by trimming the barrel hood and foot at the link pin (not a ramped barrel, I didn't want to cut the frame). I did this with careful hand tool strokes and layout fluid. It took a long time, and since the hood wasn't machine left-to-right to match the slide like the match guns there's some clearance there. If I had to do it again I'd but a lower lug cutting tool from Brownells and might consider the mill jig for holding barrels. This is only because I will likely do it again so it's a good time for me to invest in the tooling.
Regardless of what I like to do, make sure you're comfortable working on your gun before you jump all the way in. Being nervous and fretful about the build will take all the fun out of it. Buy the parts slowly over time and always cut on the cheaper parts first. Remind yourself when you ruin a part (it will happen) that you're learning and education is never free. A lot of time you can rescue a part with a little welding (I have a friend who comes to my aid all the time). Most all remember when you're done you'll have something you made that will last a lifetime if properly cared for. I look forward to handing down my creations as family heirlooms.
