Just a couple of suggestions for this installation.

1. Mask off the area around the gauge with tape, prior to bonding. It would eliminate any scraping and gives a neater install. One slip with the razor, and you have to start all over again.

2. If possible, warm the shaft, or whatever piece you are working on with a heat gun, prior to bonding, soldering, etc.

Just warm it up, not make it hot.

2. Tin the wires prior to soldering. This is just a basic good practice that helps eliminate bad solder joints.

I also like to use just a drop of flux when soldering, as sometimes the rosin core is not enough.

3. Test the gauge, prior to sealing it off. It is easier to de- and re-solder the tabs, should you need to.

We can all make mistakes.

4. Bonding the wires to the part, about half an inch down from the solder tabs, would provide strain relief for the solder joints, and minimize any flex from the wires.

The teflon tape is a good idea though, I
