Default Trial fitting the HS 1213 hinge brackets to the F1211 bearings and they are to tight

Hi all, I'm at the point where I'm trial fitting the HS 1213 hinge brackets to the F1211 bearings and they are to tight. They fit when there are no washers included but too tight when there are washers installed. I'm at a loss about what to do about it.....

The brackets are square and the stops are not undersized. Everything seems good according to the plans but the fit is just a smidge to tight. I'm guessing that installing the stabilator after the emp cone is done would be a real pain if this fit is not "slide right in" tight.

Some pictures....

Default Close tolerance fit

It is a snug fit, by design. You don’t want your HS flopping about.

About the only advice I can offer is to use 416L washers, and if that’s still too snug, then remove the paint you have where the washers would sit as even a few thousands can make a difference.

Where the instructions say to glue the washers, you can use a little epoxy around the edge of the washer (don’t use too much it as you might want change these someday, and let it fully cure before attempting install) rather than on the face to minimize washer thickness.

Try thick axle grease first instead of glue.

Default Stabilator tightness

You are correct in the fact that putting the stabilator on after the tail cone is finished is a major pain. It takes three people to do it and several times in your attempt.

I found that if you try to superglue the thin washers to the stabilator bracket it will not work. Sliding the stabilator onto the bearing would always seem to knock a washer off, so back to gluing again. And it was always only one washer.

That one elusive washer or two were glued to the bearing itself with just a little glue. And to the bracket. Finally we got everything on. The gap is way too tight for using a washer holder tool. It will go on.

I used EZ fuel lube on the washers. It is quite sticky. The washers still shift a bit but you can push them back with a small screwdriver. Installing the stabilator takes some time.

Nice way to position the stabilator; Tony Tessitore's site (it worked great for me also);

Make sure the HS 1210 hinge stops meet spec. They could be undersized and pulling the HS 1213 parts together.


For the washers I highly recommend a inexpensive tool that will make dealing with washers much easier.

I've had mine on and off several times - each time by myself with help of some tables, cardboard stock (to keep from scratching the tailcone and boxes to adjust height.

I didn't remember them being this pricey but worth their weight in gold in some places ... http://www.cleavelandtool.com/Washer...ductinfo/WWR4/

Has anybody tried 3M Super 77 Spray Adhesive or something similar?
