I decided to do a tutorial for you folks that like to set up your own guitars. IMO the notched straightedge is the most vital tool to have to set up a guitar and you can make it yourself in about an hour or 2. One cant properly setup a guitar consistantly without one. If one does not have one adjusting the truss rod becomes more or less a guessing game. Here we go.

Tools and items you will need,

Aluminum yard stick (available at any hardware store)

Hacksaw

Dremel Tool

Wire wheel Dremal bit

Small round cutting Dremel bit, (check pictures)

Small round swiss file

Feeler guages

220 sandpaper

Permanet marker

Small Vise

Here is a pic of some of the items

Start out but cutting the Yard Stck to length of your entire neck with the hacksaw. Lay the cut to length straight edge on your fretboard and mark the fret locations

Next, after the fret locations are marked, place the straight edge in the vise and use the Dremel and the cutter to start grinding the notches. When starting the notches, start them left of center of the marks becasue of the direction the dremal rotates in the notches will grind more to the right. I recomend using speed 2 until the notches are started. After they are started you can turn up the speed and do it faster. Hold the dremel with 2 hands and try not to let it get away from you. It will kick a bit now and again.

After all notches are finished, gently test fit the straight edge on the fretboard and make sure it fits (you may have to go back and grind here and there a bit more). I can stress the gentle part enough since there will be burrs from grinding. Once the notches are complete, use the small file to smooth the inside of the notches. After that is complete, use the wire brush to take care of any burrs on the straight edge. When that is complete, gently use 220 sandpaper on the part of the straight edge that goes against the fretboard to make sure it is smooth. When that is complete, it is ready to use.

You can see the relief in the fretboard in this picture of a PRS,

Here are some factory specs to go by and here is where the feeler guages come into play,

American Strat, tele, 25.5 scale, Relief .001 at the 8th fret

Gibson ES 335, (will work for LP also), 24.75 scale, no relief at 8th fret

Martin 28 series, 25.4 scale, .002 at 8th fret

Fender Bass, .014 at 7th fret

PRS, 25 scale, .004 at 8th fret

These are ballpark numbers. In my experience they have been dead on the money but, different string guages and such "may" require a "bit" different specs. Set the relief just as the specs say, dont worry about what it is doing at the 12th fret!

Also, this tool is great for checking for defects in your fretboard (highspots and low spots).

Cool. Thanks for the info.

It would help greatly if you can resize those pictures so all your words stay on the same screen, no scrolling.

Good post.

The only thing I'd add to that is that those aluminium rules can be a bit bendy and that they are not always very accurate, so you ned to be aware of the potential for error...
 
Re: How to properly check neck relief, tutorial. Vault Worthy!

Geez...I just hold the low E string down at the first fret and highest fret and see if I can slide a Fender Medium between the middle frets and the underside of the string.

ahahahahahahahahahahahahahahahahahahahahahahah! :laugh2:

That will check the relief but, it wont show any defects in the board. Also, the fall away at the highest frets on guitars that have fall away (15-22 frets) and if the neck has any defects (most epiphones and other cheaper guitars) will give a false reading also. Good tip non the less.

I have had great success with them yhey can be bendy but, not in the directions that it will be used. In the event it does bend, just hit it against a belt sander and its all good again.
 
Re: How to properly check neck relief, tutorial. Vault Worthy!

Nice! I never thought of that. I have always just sighted the neck and moved either way from there.
 
Re: How to properly check neck relief, tutorial. Vault Worthy!

Ok, I made a fretboard guage and even though it was bendy it worked really well. I saw that my fretboard on my 2001 59 reissue Les Paul was about .0005 out so I pulled all the frets.

Now what do I do?

I'm gonna need a lot of pics...........

Hang it by the chimney :)
I made a very similar but way longer article a while ago on how to actually adjust and measure relief without tools. Would anyone be interested in it?

See that dremel tool?

Might wanna stick it in your eye now :laugh2:

That poor poor R9. :D


Seriously tho..Dave, cool post! I kinda do everything by eye and feel for action/truss adjustments and it's been (and still is) a learning experience. I use the metal ruler and such to check relief and get me in the ballpark, and then tweak from there. I find that I don't like a typical setup, I guess. I prefer my action a little higher than most and very little if any relief (assuming the guitar in question can handle it..i.e. built worth a damn)
 
Re: How to properly check neck relief, tutorial. Vault Worthy!

This is a good thread BTW...thanks!

And yes, I do usually just hold the low E string down at the lowest and highest fret and then, using the string iteself as a straight edge, adjust the neck to allow a gap about the size of a Fender medium pick between the underside of the string and the top of the frets around the middle of the neck.

Sounds like Robert S. uses the same method.

I don't always measure it with a pick...but sometimes I do. I can do it by sight after all these years.
 
Re: How to properly check neck relief, tutorial. Vault Worthy!

I usually do it by sight too. Usually it ends up being around .12. Between .10 and .15 anyway. I'd do that thing if I had a dremel.

Damn... Dremel GAS!
Cool post Odie ;)
