Vintage 90s Mountain Bike 3x7 to 1x10 Conversion Using Same Wheel

I turn my 1994 Trek 930 mountain bike from a 3x7 to a 1x10 modern Deore set up. No wheel build this time - just changing the freehub to accommodate a modern 10 speed mountain cassette. It was an interesting experiment and I was unsure right up to the end if it would work out.
