Tension is achieved by the rear spring. Remove needle bar and holding machine in left hand by the tube, depress armature bar with left thumb and ease it upwards until contacts meet. There should be enough tension so you c&n see the front spring rise a little more when contacts meet and you release your thumb - then you've got it right. You can buy a gauge from a tattoo supply house to duplicate this same tension when you replace the rear spring.
When coils are set where you want them, add a drop of liquid thread to the machine screws the last time you turn them in. This will assure a secure and tight fit This can also be done with the two screws that hold the posts.
If you choose to wind your own coils, use #24 insulated magnet wire and a hand turned coil winder. Use a point file to keep points clean.
Listen very carefully to the buzz of your machine. You might have to turn the contract screw in or out just a little until you get that right sound, it should sound real smooth. Listen carefully to the sound of the machine as you turn the contact screw and you will be able to "hear" the ideal setting if you pay attention. It won't be choppy and clatter, yet it will have plenty of power and have a long enough stroke to allow the needle bar to travel between 1/16 and 3/32 inch up and down.
Once you get used to the "purr" that tt makes when. it. is running good, you will be able to keep your points set at optimum efficiency quickly and easily just by hearing it. When it begins to "purr," take your foot off the pedaJ and tighten the set screw to lock the contact screw in that position. Then push the foot pedal again to be sure that it is still tuned "right" and doesn't need any further adjustment,
