Need help perfecting the budget build hemi swap

What I typically do when working with AN fittings and SS hose is:
After I mark location of my cut I wrap the spot VERY TIGHT with electrical tape. Only 3-4 wraps but do it tight so its almost stretching thin. Take the thinnest cut-off wheel you can find and spin it up fast. Slice through hose strait and steady when you get close to almost through twist the hose so you have a clean cut. Leave the extra hose with tape on it for safe storage. On the needed hose carefully and slowly pull tape off. All the wires should be nice and tight still. Spray down the inside outside of hose end with thin oil (wd-40 is too thin) Twist or press coupler down to it bottoms out. Screw in AN fitting. Bingo! I keep a super clean sealed container of mineral spirit's around to rinse the hose thoroughly inside and out.
