I don't quite get this. Seems to me LF is far simpler than any roll film camera. Which tolerances are very small?

It
is a simpler design. but it is not mass produced. Wisner and Deardorff are hand crafted in small volumes.
A little careful work with a table saw and a ruler with 1/32nd inch demarkations will get you within your tolerances for the wood bits. Better yet, spend $17 on a digital caliper from Harbor Freight and USE IT when you thickness plane your wood. You'll get your wood dimensions right and have no real tolerance problems.
The metal bits are no more difficult to make correctly. Just ask BarryYoung. The real reasons why LF cameras are very expensive are 1: they are hand made by craftsmen... at least here in the US. 2: In order to cut the wooden pieces you see in the camera, you will waste wood no matter how efficiently you cut or plane. Figure it takes at least 50% more wood than you see in the camera itself. The same is true for brass. And by the way, a 12"x12" sheet of brass for parts is about 1/4th the brass you need for an 8x10 and that amount will still cost you upwards of $30. That doesn't count the cost of buying the equipment needed to machine the brass and wood.
So then, the total cost of materials including waste, labor, amortized equipment costs, rent of building space, utilities... it goes on and on. All of those cost are built into the price of the camera. If your shop builds 12 cameras a month then you are spreading your fixed costs a lot more thickly on the individual camera. If you can double your volume without requiring more space or more equipment then you can decrease your unit price somewhat... the non fixed costs such as materials and labor are unchanged though.
Think about your $65,000 BMW. Does the raw material that went into it really cost that much more than what went into my $17,000 Hyundai?. Yes it is more expensive. Better leather, wood rather than plastic. Stuff like that. That doesn't account for the delta though. Is it the labor cost? Sure. Is it the nameplate on the hood? right again! How about the high tech components? Yep.
All that being said, A brand new Wisner should justifyably be more expensive than a new camera built by me using the same design. Wisner's cost of brass and cherry are probably lower than mine due to purchase volume but his labor costs will be substantially higher because he employs professional craftsmen while I am just a hobbiest. His fixed costs are substantial while I have none.
Maybe I could sell one of my 8x10's for $1000 or so and it would be a good value. Wisner should be able to sell the same camera for $2500 and make a decent profit. But $4,000? That doesn't seem so reasonable.
