Do you follow a set of steps in setting up neck relief and string height. Any specific advice on setting up telecasters with the truss rod adjustment in the heel (strats too I guess.) Thanks.
If you aren't swapping the string gauge you can assess the truss rod with old strings before you take them off. You have to get used to the particular guitar and make a guesstimate ( based on experience ) and this is the first part of the set up.
Vintage style Fender rods can often be quite tight and remember that it's going to take time for an adjustment loose to show it's full effect sometimes.
Once you have the starting point for the truss rod you can go through the set up. Half the thickness of your high E at the 7th fret when you fret the G ( reference string) at the 1st and 12th. In an ideal world then when you fret 10th and last it should be dead flat. Sometimes a slight fall away is present usually around 15 to the end but it varies and this is hard to assess by eye if you aren't looking at multiple guitars all the time.
If your happy the relief is likely to be ballpark string it up and set the action. If it still is out you are going to need to take off the neck again and readjust.
When you remove Fender necks with the heel adjuster you should use a hand driver carefully to reattach it starting the screws with your fingers to feel that they are in the existing threads. Only tighten to lightly grip (no crush the wood and bend the neck plate like you see all the time.) This is very important as this neck is going to need to come off a lot of times over it's life.
Don't waste time with radius gauges use an action gauge or engineers small steel rule, measure top of fret 12 to underside of each string.
Now check the nut hight by fretting on the second fret. You need a hair of a gap over the first fret. Only do this after the truss rod is correct and the action is your hight. Each time you cut the nut slot reset the action before looking at the gap again.
Finally with the relief, nut and action set correctly ( for you ) intonate using the 3rd and 15th frets as reference point.
If you have issues now it is either your action is too low for your pick attack or there's an issue (issues) to deal with separately.
