I have a Ridgid contractor saw (TS3650) and want to try a dado set I inherited with my dad’s radial arm saw. When I went to install it with two blades and four chippers (for a 3/4 dado), I found that the arbor wasn’t long enough to use both blade washers. There wasn’t enough thread outside the washer to attach the nut. I can leave the washer off and tighten the nut directly up against the blade but I’m not sure if this is safe.
At 1 1/2 hp, I realize this isn’t a powerful saw and I’ll have to be conservative with the width and depth of dados I cut but I’d like to use the set if possible and 3/4” seems like a useful width.
Any thoughts?
