Play in Tiller

[Tim D.]

It seemed appropriate to move to this thread. Here are some pics I took today while I was down for a sail.
My first reaction was doh, when the tiller was down all the way the slop went away (note to self, get another tiller that curves up as mentioned by others)

But then I realized even the slightest lifting of the tiller and the slop was evident.
Upon closer inspection it was clear the it did not stiffen up until the fork engaged the clamping not. One can look at the second picture and see where the wear is on that clamping nut.

It seems to me that unless it was designed poorly, that it must be so worn that the fork does not rest on what appears to be a shoulder above the clamping nut.

Can anyone point me to a picture of another tiller head so that I may better understand this?

Thanks Tim
