Your tool holder looks like it is defective. It is not made for use with riser blocks because Sherline does not make one; they make the 3018 and if you need a riser block they sell the 3016 riser block. You might give them a call and see if they will swap it out for a new 3018 of the correct height. If you cut this one down and mess it up then you're going to spend the money for a new one or will have to make a new one from scratch.
If you intend to cut it down then be sure you cut it so that the tip/bottom of the blade is at the exact center line of your particular lathe. Every lathe is different so find your center line and be sure the tip of the tool does not go above it; you can go 0.005" or so below center line but not above it or the tool will not cut well.
1/2" is a lot to take off with a fly cutter. I suggest you bandsaw off the excess and then fly cut it to final dimensions.
