With a railroad tie.If you have turned rod all the way to it's limit, you are likely (though not necessarily) to have back bow, where the neck has a hump in it, which is likely why you are having to raise action.
You can't assume that you can get super low action on any guitar. I can get it that way on a few of mine, but they have had the nut cut and frets levelled by a pro.
Probably easier to look up you tube for set up and start over.
How are you measuring relief/checking straightness on the neck?
The guy could fix it for you:Should I loosen it off a bit? The neck doesn't look straighter but I ended up getting so much more fret buzz than I had before and had to raise all my saddles way up. The action doesn't even seem much better so I'm pretty pissed off right now.
Oh god. Use your hand and a screw driver, please. Feel the tension as you slowly turn it and keep an eye on the fretboard. You’ll see it adjust. No screw guns.
are you sure you are turning the rod the right direction? some strat necks have a two-way 'dual action' truss rod which can adjust the neck bow in either direction to correct a reverse warp as well as set correct relief. looks like there's a big concave bow there.
Sparkling or distilled water?I'm surprised the impact wrench didn't work. No worries though. You'll need to soak the neck fully submerged in a container of hot water for at least 7 days. At the end of that 7 days, you'll need to put the neck in the oven with a brick underneath the middle and a brick on the TOP of each end. Heat the oven to 400 degrees and "roast" it for about 2 days. I'm sure you've heard of roasted necks being the new thing now. If that doesn't work, contact Warmoth. They'll get a new neck to you for a small charge.
Is it not turning? I once had to use WD-40 and let it set overnight. Turned easily the next day. If you are having to force it, you're going to break it. It's really just that simple.I know dude but the thing is to hard to turn so I used the impact wrench to really crank it but I swear it's not even having an effect.
