Tail wheels, or is this forum really dead?

Not a completely true statement. Â*Have you ever used a measuring
wheel?
===================

Â*Virtually every distance measuring wheel available on the market
today has the pivot point well ahead of the patch.

The lufkin PSMW38 does. Northern's rotatape does. So does every other
RolaTape listed. DriVall Fencing's units do. Â*The DuraWheel does. So
does the TruMeter. So does the Gill.
And EVERY measuring wheel I've ever seen, unless you DRAG it instead
of pushing it. And dragging is not accurate because you unload the
wheel, rather than loading it, over obstructions.

Let's talk apples to apples here. The measuring wheel is a hand-
held device and will pivot both along the handle axis in your hand,
and swing side-to-side. We have TWO axes of motion here, where there's
only one for a tailwheel or nosewheel. It's not the same effect at
all. If you were able to make your wrist rigid so that the side-to-
side swing was impossible, your instability would disappear.

Who said anything about instability? Not me. Properly handled, pushing
a measuring wheel is dead easy.. I'm saying the measuring wheels and
tail-wheels - and bycycles - are all set up the same way FOR
stability.

I mistook your meaning. Sorry.
