Mountain Dewd is correct . . as I am building a late lancaster from TVM now.
One thing that is very good about TVM for the price, is that they get the essentials right. They line up the lock, touch hole, trigger and barrel. Barrel & Tang are inlet, touch hole lined up and trigger inlet and set . . so the critical points of shooting the rifle are done there, and done well. Those things that must line up, line up. In that sense, most everything else is aesthetics . . (which are important too.)
The lock is about 98% inlet too. In fact on mine, being my first build I was scared of the delicate mortise cuts for the lock and so rather than risk messing up the wood with a file or chisel, I took sand paper and sanded down the edges of the Siler Lock plate until it fit into the mortise. It took quite a while and might not have been kosher, but the wood to metal fit in that lock area is good with no screw ups.
I 've spent about 100 hours on mine, rough guess so far and I am not done . . . I am slow and nervous . . . but my life saver has been this forum and finding a guy who has built several rifles in my town to spend time with and to coach me. He does things the right way. . that might not have been the way I would have suspected, to my detriment. . .some things are a bit counter intuitive until you see how its done by a builder. I'd highly recommend the book The Gunsmith of Greenville County . . . Youtube can be a good resource too.
You'll know how to use a chisel before this is all over . . . may not love them . ( I still hate chisels ) . . . but its the #1 tool you'll use, sorry to say. . . along with it comes cheap candles for blackening parts to inlet with those dang chisels.
