No joke.
It's aluminum and a 4', and it's crowned just a bit.
I've read here and elsewhere that aluminum can be machined with WW'ing tools. But I don't know for sure what SORT of aluminum that straight edge is.
My jointer's knives are plenty nicked right now, and I'm just about ready to plop in the second set. They are HSS knives, though, not carbide.
I am actually thinking about shaving off a few thousandths to get a straight edge on that sucker. But I'm going to wait until tomorrow morning, AFTER tonight's Norco wears off.
Seriously, though, I'm wondering if there isn't a stronger alloy or something in there, which would possibly change my consideration.
P.S. the SE was purchased for tile work, and has worked like a dream. But wouldn't it be cool if one could joint a cheepo?
