Skil HD5510 (1993) vs. 551 (1983) vs. 5510 (1986)

Inspired by that Skil HD5510 review, I’m going to ask you all this: how does the 1993-current HD5510 5-1/2” trim saw hold up over such older generations of it, like the original 1983 model 551 and the 1986 model 5510?

1992 was the first year that Skil and the U.S. division of Robert Bosch merged; four years later, RB would buy out Emerson Electric’s 50% (or whatever) share of the joint-venture (Emerson Electric bought the then 55-year-old Skil in January 1979). I’d like to think this was when the quality of most power tools began to decline.

How many of you actually have a circa 1983 model 551 or a circa 1986 model 5510 to show us here?

Thank you,

Ben
