diekke Posted February 12, 2009 Share Posted February 12, 2009 Hi, it's one week that I had a problem with my dark fire when I pull out the MCK for tuning the dark fire, the powerheads doesn't tune the G string and I have to tuning it manually. what's the problem? thanks Diego Link to comment Share on other sites More sharing options...
elantric Posted February 12, 2009 Share Posted February 12, 2009 Might have to clean the tuner contacts Read the "unofficial Owners Manual" http://forums.gibson.com/resource.ashx?a=8 Try the following: Tighten the hex nut of the Powerhead of the low E-string 1/8 turn. If it doesn't help, turn it 1/8 turn again. If it still doesn't work, unscrew the Powerhead by loosening the hex nut. Make sure that the contacts are clean. Is there a brass sleeve inserted in the hole of the headstock? If so, remove it. Screw the Powerhead in again. Link to comment Share on other sites More sharing options...
MCK Posted February 12, 2009 Share Posted February 12, 2009 Diekke, a number of us had this issue. I took few remove & installs to get it right and eventually what it came down to was how much I tightened the hex nut on the tuning head. It is a little scary to keep tightening it 1/8 turn at a time not knowing how much those threads can take but it eventually worked out for me... Thought for Gibson... Perhaps you could tell us how much torque we can safely apply. I do have a small torque wrench and could do this in a more scientific way if you have the guidance for us...

boardusmcer Posted February 12, 2009 Share Posted February 12, 2009 how small a torque wrench are we talking? I can't imagine those screws are going much higher than 40-50 inch lbs. could be wrong, but it definitely makes me nervous playing around with it :-O, haha Link to comment Share on other sites More sharing options...
MCK Posted February 12, 2009 Share Posted February 12, 2009 Absolutely same concern here. It was very un-nerving to keep tightening those nuts until the problem went away! I am thinking of something like this with a 10-100lbs range covering the need. We just need a guidance point... http://www.amazon.com/GearWrench-85052-8-Inch-Foot-Pound-Micrometer/dp/B000TDEFR2/ref=sr_1_14?ie=UTF8&s=hi&qid=1234494617&sr=1-14 Link to comment Share on other sites More sharing options...
photonutalan1 Posted February 12, 2009 Share Posted February 12, 2009 No, no, no! That wrench is calibrated in foot-pounds; what we want is inch-pounds. Think about 25 inch-pounds max (this is what seats my Olympic rifle in its stock); my Dark Fire (which works perfectly) is 12 inch-pounds. Link to comment Share on other sites More sharing options...
MCK Posted February 12, 2009 Share Posted February 12, 2009 Thanks for catching that error and establishing the benchmark torque. I was simply shooting from the hip! ;-) Can you share with us which wrench you have as it obviously has managed to measure your as-is. Link to comment Share on other sites More sharing options...
photonutalan1 Posted February 12, 2009 Share Posted February 12, 2009 Hi MCK; I appreciate the humor, and your many contributions to this forum! I bought my wrench over 35 years ago from a company now out of business. A good source nowadays is <www.brownells.com>; they stock just about everything for the marksman. You should not have to spend more than about $35.00 for a 1/4" drive wrench of good quality calibrated in inch-pounds. Mine does not have a dial gauge, it is set with a vernier thumb-screw adjustment and the clutch simply breaks loose when the desired torque is reached. It is fool-proof...which for me is a good thing! Link to comment Share on other sites More sharing options...
MCK Posted February 12, 2009 Share Posted February 12, 2009 Hey thanks for your compliments! I enjoy the interaction here and try to give back a little where I can. The link is great but can get one in trouble if viewed at work! Thanks for sharing. Link to comment Share on other sites More sharing options...

photonutalan1 Posted February 14, 2009 Share Posted February 14, 2009 FWIW. For those who have been following this thread, but don't want to invest in a torque wrench: insert the long end of an L-shaped hex (allen) wrench in the hex screw; using just your thumb, index, and middle fingers on the short end of the wrench, tighten the screw; when you've tightened as much as you can, you will have applied 10-12 inch-pounds of torque to the screw.

rsx Posted February 14, 2009 Share Posted February 14, 2009 is this the same for the GOR? i have been experiencing this problem too. Link to comment Share on other sites More sharing options...
elantric Posted February 14, 2009 Share Posted February 14, 2009 All Tronical versions can suffer this problem Clean the Tuning contacts - could use a rubber eraser Better still - remove the tuner and spritz a a small squirt of Caig Deoxit" electrical contact cleaner on the Tuner electrical contacts - then reinstall the Tuner - careful not too much torque or you may damage the thin black Tronical circuit board. http://store.caig.com/s.nl/sc.2/category.188/.f Link to comment Share on other sites More sharing options...
