Schacht introduced its Standard Floor Loom at Convergence in 1978—our first floor loom ever! Its weaving widths, wood, castle style, shaft options, and treadle options have changed since then. Here's how it changed (as best we know now, based on surviving company records):
| YEAR | CHANGES |
| 1978 | introduced 4-shaft, 36" and 42" weaving widths, probably 6 treadles, low castle, maple |
| 1980 | introduced 8-shaft and 4 Now-4 Later (an 8-shaft loom shipped with space for 4 more shafts) options, probably 10 treadles, low castle, maple |
| 1983 | loom with 45" weaving width replaces 42" (officially named 46" Standard Floor Loom) |
| 1987 | introduced high castle option for both weaving widths |
| 1996 | added cherry and oak options; oak was discontinued in 1998 |
| 2001 | discontinued 4-shaft looms in both widths 4 Now-4 Later available with 6 treadles or 10 treadles |
| 2018 | discontinued 10-treadle option wider loom renamed 45" (though the loom itself did not change) |
