I've been struggling trying to set the barrel/cylinder gap on this gun and I've about reached the end of my rope. I'm sure it's something I'm doing wrong.
I've tried setting the gap with a feeler gauge, .060, before securing the barrel nut. I figure I have a 1 in 100 chance that after securing he nut the gap is the same as before. Lets say the gap closed a bit, I'll remove the shroud and back the barrel threads off 1/4 turn, secure the nut and bammo, the gap's now .090 or more. So I try again and tighten 1/8 turn, secure the nut and the gap is closed, completely closed, cannot shove a .001 gauge in the gap.
Maybe the frame or barrel threads are hosed, I don't know, maybe I'm over tightening?
HELP!

Ok, to start the gap should be .006, thats probaly what you ment but just
in case thats what it is and I usally set mine around .004.
Next figure where the high spot on cylinder is, there will be a high spot.
So now when you get the highest cylinder hole set at your .006 just
drop open the cylinder press your free thumb on the barrel tightly
and then tighten your barrel nut.
Also don't force gauge in there to set it, just a light drag it right.

Simple man method. This may be totally wrong and if it is please let me know.
I place a .003 feller gauge between the cylinder and the barrel and screw the barrel down until the gauge becomes snug. Then I tighten the barrel to the shroud. Now I remove the gauge. Last I index the cylinder until I know that it is not dragging.
This has worked for me for many a year. R S

this works for me to , drop cylinder and hold barrel and tighten , that way you can feel if the barrel starts moving but if you put a little bit more pressure it will stop .the same thing drove me crazy 
the first couple times

It sounds to me that the threads on the muzzle end might be dirty or gunked. I would start first by completely cleaning the threads of both the nut & barrel. You get it to where the nut will be able to spin (onto the barrel) a revolution or two by itself, when you give it a good spin with your fingers. Make sure to clean the other end too, along with the frame threads.
Once you have the threads squeaky clean, apply a couple drops of gun oil to the threads & assemble.

Like CF said, clean the threads of the barrel and nut thoroughly. I then apply a light coat of oil to the threads. Following is my barrel tightening method.
1. Spin the barrel onto the frame and stop when it contacts the cylinder.
2. Back the barrel off enough to get your feeler gauge between it and the cylinder. I use the .002 gauge on all of my Dan's.
3. Next pull the trigger 6 times checking the gap at each cylinder position.
4. If you encounter a position where the feeler gauge will not fit, adjust the barrel so that it will. Restart your count.
5. After you have completed this step, you will be at the tightest position.
6. Leave the gauge in the gap.
7. Slide the shroud over the barrel.
8. Spin the barrel nut on until it makes contact with the shroud.
9. Use your EWK barrel tool to very slooooowly apply tightening pressure to the nut. This will ensure that you get the barrel nut tight but do not change the gap.
Occasionally the barrel will turn and tighten up anyway. I have 2 Dan's on which this happens frequently. You just have to take off the nut and re-gap the barrel at the current position and be more careful next time.
In my opinion, if you try to use your thumb to prevent the barrel from turning it can turn a very small amount without you being able to feel it and that will change your gap. JMO

You folks are so smart!
Thorough cleaning and holding the barrel with my thumb did the trick!
Now, off to the range for some fun. Thanks very much.

Zoommb is the one that told me about the thumb trick a few years back,
looks like he no longer recommends it. That's Ok...it's quick simple...
I'll own it
