Mokey, I'm far from an expert, however, while no bloody RTFMing, I've watched a lot of videos and can help with all the beginners questions... for advanced features... RTFM or watch some of
these videos (in reverse order).
My only regret is that I already have tools this makes redundant like my Domino, Leigh D4R, Leigh MFT...
My Woodpeckers Corner Jig, about 20 holesaws, all my forstner bits can also be replaced with the aid of the Shaper Plate which is next on my review list.
If your first cut is too short... Take the second cut from the longer end... LBD
