missis sumner Posted June 10, 2017 Posted June 10, 2017 I'm trying to lift the action on a Yamaha RBX A2, because although it's easy to play the fret buzz is doing my nut in. The neck seems really straight. I've tried to loosen the truss rod - but it just feels "springy" - in that the rotation I think I've put into the adjuster, just moves back when I release pressure. I've tried tightening it, in an attempt to free it off, but this springy feeling happens in both directions, probably after about a sixteenth of a turn, if I'm being optimistic. Any advice on how to proceed, oh, learned ones? Quote
missis sumner Posted June 10, 2017 Author Posted June 10, 2017 (edited) Update: Nasty big crack noise - but I think I've got it moving. Followed by another big crack noise, followed by a slightly better crack noise. I'm just going to give it a little more... Edit: Yep - got much better the more I adjusted it. Glad I was brave. On to string height... Edited June 10, 2017 by missis sumner Quote

[/quote] I experienced exactly this when working on a customer's Yamaha bass a while back. When the first crack occurred, I really thought the rod had snapped but actually all was good. I did then take the nut right off and applied some grease before proceeding. Quote
missis sumner Posted June 10, 2017 Author Posted June 10, 2017 (edited) Did you have to take the neck off to apply the grease? (I've never taken a neck off). Anyway, I've sorted mine now. There were a few more creaks but they were decreasing as I went on. All set up - now it's time to play! Edit: I have other Yamahas, and never experienced this problem, but I suppose the plastic RBX A2 is a bit "speshul". lol Edited June 10, 2017 by missis sumner Quote
T-Bay Posted June 10, 2017 Posted June 10, 2017 Use a syringe or pipette to drop a bit of penetrating oil (not wd40) e.g plusgas, then after a week put a couple of drops of 3in1 oil or similar on. If you can get it out then a bit of copperslip grease is ideal. Quote
missis sumner Posted June 10, 2017 Author Posted June 10, 2017 Doesn't Plusgas have a freezing (cold) effect? You've used it around wood? (Or am I thinking of another product for removing rusty exhausts?) Quote

[/quote] That is the propellant in the can which helps in circumstances like you describe , the actual plusgas is a thin oil that also has a substance in it that helps break the rust down. You wouldnt use a can as it would put way to much in. Use a syringe or pipette as I suggested and you can put just a drop or two exactly where you need it. It wouldn't harm the wood but won't touch it anyway. You don't want to drown that area in any oil based substance. I used to do a lot of target shooting and our armourer used the term 'enough oil to coat a sparrows feather', it's fits in this instance too. Less is more in this case.

missis sumner Posted June 10, 2017 Author Posted June 10, 2017 Ah, I see. Thanks for clarifying. It's all working now; busy playing Queen! Quote
