Step 3 Electrical/ soldering
OK here is where I officially turn into a retard. I have no finesse when soldering, I know all the tricks and have all the right tools but I just can't get a good handle on soldering such small intricate stuff. You need to solder a small length of wire to the center post of your 901
atty connector (Fig 13). If your
atty connector is a press fit in the nose cone there is no need for a ground wire. If you feel your
atty connector is to loose you will need to solder a ground wire from the
atty connector to the nose cone. When you solder the
atty connector you really need high heat soldering gun. If you use a low watt gun you need to keep the heat on for a long time and this could melt the silicone gasket that isolates the threaded adapter from the center pin. Unless you remove the center pin to solder, I don't because i find the silicone gasket tears very easy, you could wind up with a short. You also need to remove the large resister on the laser emitter PCB (Fig. 14). You could either cut it off or unsolder it. The positive terminal spring that is soldered to the top of the PCB needs to be modded. Its just a coil of wire, in fear of the end of the coil rotating into the vent holes in the battery makes me nervous. What I did was bend the cut end over towards the center (Fig 15).
