Its not easy but I was able to put a 1/4" rotary file bit in a 90 deg angle grinder and slowly grind away at it. Sounds really dangerous but it wasnt to bad just dont give the grinder full gas and it will work.

Default Technique from E's site

Here's a link that shows how another builder did this. Not sure it's any easier. I'm still several weeks away from this step.

so why should I bother filing it down. I understand maximizing the aft angle for landing, but do I care how much forward the angle is? How often am I going to push the stick full forward? Just curious. I am sure that someone is going to flame me for this post.

The only way I was able to do it, and get the two stops to hit together, was to use thin strips of 100 grit sand paper (~1/4"), threading them around the tube that the bracket hits with the rough side on the stop side. By holding some slight control force against the stop, it was possible to then pull the sandpaper out. This caused the sandpaper to remove a tiny bit of the stop ( I'm guessing about 2 atoms ). Repeat for a long time until the stops hit together. Fortunately, when I got the two stops hitting together, it was within spec. for travel. There is probably an easier way . . .
I just completed this process. Neither forward or back angle was quite up to minimum when I started, but I focused first on getting both sides hitting the stops simultaneously. I cut two strips of paper 8 1/2 long and 5/16" wide, held the stick bases neutral and threaded them down past the top stop, around the tube that contacts the stops and out over the bottom stop, one on each side. Relax the stick forward against the stop and tug each strip. On mine, the right was tight, no contact on the left. Hold the stick back and test the other way with a tug. Mine was tight on the left, no contact on the right. I then cut two strips of cloth-backed sandpaper, one 220 grit, the other 400. Worked on one side at a time with the 220 until there started to be some resistance to the tug (always using the plain paper strips to check.) Like in the post above, use the stick base to maintain pressure against the sandpaper on the stop you are sanding. Then finished with 400. My sandpaper strips were over a foot long and I would pull back and forth so I didn't have to keep threading it thru. Took awhile but was easy and foolproof. Best part is, when I got both sides contacting simultaneously, the stick travel was perfectly in the middle of the desired range.

I'm at this step right now .. it's so close, but I can fit a piece of paper under the right stop .. dangit! Anyone with additional advice before I proceed with Don's sandpaper method?

Just a follow up on this for anyone else that hasn't got to this point .. not as bad as it sounds .. while it seemed like it took us a 10 hours to file the stops to spec, from start to finish was about an hour and a half and it's perfect. We just used a large file and a digital pitch gauge. File, refit, measure, repeat, etc. You do have to remove the linkage to easily get to the bottom stop.

I also just did it and was lucky, only needed to file the top left stop to get both stick to reach the stop at the same time.

The bottom stops were perfect without me touching them.

This part will test your patience.

I worked on the stick stops and made all four points to the near perfect, a piece of paper will engage almost equally on both sides, up and down, and my angels were nicely just about the range it has been given 13.6 forward and 23.1 aft.
Then I installed my elevators only to find out that the stops are getting engaged at the stick before the elevator hit the stop and not even close to the full deflection of 30 and 25 that is called for. So, I filed the tail for the full deflection range on the elevator and now with .3 degree of 30 and 25 degree but need to go back to the limits on the stick and file those, presumably quite a bit to make sure I am not being limited by the stick. I guess this will be a six-month task if I work on it 8 hours a day  So not looking forward to it.

I found the stops for the stick just needing a touch on one of the up stops to meet specs, there was a bit of filing down the back though to get the required degrees. More so with the up stop.
