How about just loosening the bolts a bit + some grease? The assembly is not going anywhere...:)

I tried going very loose on the bolts, but for my setup, just shy of what i would consider "too loose" ended up still being a bit tight for the tube.

I was over thinking everything until i thought of the hone - thats for sure. With the hone it took less than 5 minutes of tweaking to get a great fit.

Okay all,

I'm currently working on the control assembly and Waiex mixer. I've installed the 5/8" ID x 3/4" OD bushings in the control tree and have removed the powder coating from the control horns (SNX-C04-08). However, I still cannot push in the control horn due to a really tight fit. The plans say to line ream the bushings to obtain a "snug but freely rotating fit."

Any suggestions on what to use to line ream these bushings? I don't think they will need much, but it's a small enough diameter that it is hard to get sandpaper inside to ream them evenly.

Sorry I can't help you more on this one Eric, but I believe the sandpaper thing is all I could figure out. I took a small sheet and rolled it up, put it into the brass bushing, and then just twisted it around for a while. If you do this, be careful though; I was able to get my passenger stick perfect with no slop, but my pilot side bushing is reamed a little too much and I have a little slop. Not enough to worry about, but one day I'll take it apart and replace those bushings and ream them again. That job is sort of a PITA so good luck! I'm sure there's a better way but I never could figure it out...

Sorry!

Mike, that is kinda what I figured. I don't really want to buy a 5/8" reamer just for that because it is such a small amount of material that needs to be taken off. But like you said, I just don't want to get any excessive slop in the system...if I can prevent it.

Thanks for the reply!

I am starting on the control assemblies part of the build. I have read through this thread and appreciate the great info. I have everything fit and ready to drill. I don't want to rush this so thought I'd ask a question first.

How are you guys drilling for these taper pins? Is everybody spending the big bucks on the tapered reamers? I am building a Waiex so the plans call for the taper pin in the mixer assembly but thought I might put them in the control sticks as suggested in this thread. I just need some instruction on how to drill/install them.

Thanks!

You mean kinda like this....?

Yep that's basically what I have found so far. Thanks for the info! For anyone that hasn't already found out, Aircraft Tool Supply has the reamer for $30 which is considerably cheaper than ACS.

Ordering now...

That's what I bought, though I haven't got to the point of using it yet. It sure looks like it will do the trick.
