@ FrankenWashie If you want, I could do a mini-tutorial of sorts, documenting exactly how I went about setting-up the trem system on my HotRod Strat, there's a couple of tools that will make the job of setting it up a lot easier, one is a special tool you can buy from Stewmac, called "The Key", it makes setting the individual string intonation so much easier, the other tool, which you can easily make, is a specially-shaped piece of wood which blocks-off the bridge so that it rigidly sits parallel to the guitar body, once the piece of wood is in place, you simply tighten the tension on the Trem springs, when I go to put some new strings on my Hot Rod Strat after installing the new pickups, etc, I will take some pics as I do the setup on my Hot Rod Strat, and I'll explain exactly what I do, step by step, hopefully that will be useful for other forum members who are building guitar kits that feature a double-locking trem.
