>Ernie, I had similar experience with maple using a #78. I was working a 6 ft long piece to make some fancy moulding. I needed to decrease the thickness from 3/4" to something like 3/8" (this is an (window) undersill piece). I attacked with a freshly sharpen #78. Took some playing around to get depth adjusted right. I could get a nice fine shaving, but I was going for major wood removal here, so opted for some more depth. Pooped me out in a hurry and ended up taking a couple of nights.
Because of the final moulding surface profile, I actually switched to my L-N 40 1/2 to hog it down a bit. I then did final square up with the #78.
Couple of observations: the lever adjuster on newer #78's isn't that easy to use for fine depth adjustment. I kept going from light to heavy cut with barely any lever movement. I also have an early #78 without the adjuster. It was actually easier to tweak to the desired depth. Bugbear would be telling us to use a screw-adjusted Record #778 anyway. (Got my eye open for one of those)
Even with the #78's fence, I had to work hard not to bevel the rabbet. I had to correct the unwanted bevel several times. I cheated and cocked the cutter a bit to do this - sort of like a lateral adjuster does on a bench plane.
I also thought the #78 was a bit small to do really long work. I wonder if a #10 1/2 with a cleat acting as guide would be better for long rabbets??
