Folks,

I'm in the process of installing a larger nosewheel fork on my 6A - kinda
like Bob's recently unveiled craftsmanship.

I am using a new fork made to fit the stock nosegear leg.

In putting this together, I realized that the steering stop doesn't make
full sense to me - especially when I will be pushing my plane back in to the
hangar.

I have seen other planes with full swivel nosewheels (Grumman's come to
mind).

Why not?

Someone educate me!

Not sure. On my plane however there would be interference between the forward wheel pant and gear leg fiberglass fairings.

In practice I find pushing the plane backwards to not be a problem.

Hello Ralph,

I think the prop arc would and or could interfere with the nose wheel
assembly under the right (or should it be said wrong ?) conditions.

Well, I wish Grummans had full swiveling nosewheels, but they do not.
They have stops to prevent rotation past 90 degrees both ways. The
problem is the wheel pants COULD end up in the prop arc (don't remember
if the tire does) which would be expensive. Sooo, I put the socket head
bolts back in!

As unlikely as it seems that the assembly could get into the prop arc in
normal operation ..... I've rolled backwards down a slight incline with
engine at idle, and the bolts stopped the nosewheel at 90 degrees,
stopping the backward roll. I had my eyes inside the cockpit ad didn't
realize I was rolling backwards until the nosewheel came up against the
stop.

It surely would be a good 'mod' to go full circle ..... at our Grumman
conventions, steering a plane backwards through a course is a main event!!!

I probably should have said this before ...... The problem is usually caused by using a too-short towbar. Towbars are usually short so they can be collapsed and put in the airplane when you're not at home base. I have two ..... a longhandled one for the home hangar and a short one for traveling. Make your towbar long enough so that you can push on the prop with one hand (NOT THE SPINNER) and steer the plane with the other comfortably. Why not the spinner??? Over time they'll get small cracksin the fiberglass and fail at the most inopportune time. Aluminum spinners have been known to acquire dents from pushing on them.

After deciding on a 3-blade prop (Catto), I realized this might be possible. After shoving Mojo into her hangar many, many times, I'd think it not worth the trouble. Keep the breakout force to spec, and on pavement it's very easy to do. Wrestling an -A backwards on grass is another matter altogether- best done with help, nosewheel in the air, (tail pushed down), and helpers pushing on wing LEs...
