What's the group feeling for the amount of  toe-in/toe-out required for an HR-II?  I have specs for the F1, but nothing  for the HR-II.  I've lurked on the F1 forum and there's some debate on  this.

  

 Thanks, Vern

And would that be set in a level flying attitude  John? like I would do.

Thanks for the quick reply.  I will set it to  zero in the unloaded condition.  I also presume that the flats on the gear  legs should be set at 90 degrees to the firewall.

Hey John, 

I thought you wanted to set it to zero with the plane in a level flying attitude and weight on the gear. Not in an un-loaded condition as in the previous post.

I got 4 steel plates approximately 12" square 2 for the left an two for the right. Put grease between them, rolled the mains up on them, leveled the airplane then set the toe in.

We have done this on several airplanes and none of them have tire where issues.

Hmmm.  John is the design authority, but I've  read Vince's posts on the F1 Forum that uses the greasy-plate technique.   However, it's my recollection that the geometry of the gear is different on the  HR-II and the F1, so I'm reluctant to blindly follow along the F1  recommendations.  Until this is resolved, I'm not drilling the  feet!

Vern,



I guess I miss understood. I thought you had already drilled the feet and were doing a final alignment. The un-loaded condition is correct for the mounting of the feet, that will get you close. Usually the gear will require an adjustment once the plane is complete. That's where the greased plates come in. That process will help you take final measurements and shim the axles to achieve the zero toe in.

OK, I get it.  zero toe-in when drilling the  feet (I'm leveling the engine mount on the bench and will mount the feet at 90  degrees to this).  Adjusting loaded toe-in comes later.

 Thanks guys!
