Oh, YES!!!! Yes!!
How can we do this?
One of the reasons I got so good at scratchbuilding is that I can't afford to buy all the aftermarket stuff. My SO chastizes me even when I get a kit (hence, I often start from just raw plans and build the whole thing) Thankfully I still have all the tools I got years ago when I could afford them. Unfortunately, I never got a metal lathe or I would have made the barrels for the FlaK guns as well.
