Adjustable Stop Collar verners

Got two - both have small gaps (1/64"?) Not a problem because it is only a small portion of 0.001" when rotating the collar.

If the pix in the 'offering' is accurate, there should be a gap between the ends. The scale goes from '0' to '62'. One full turn increments 1/16" or 0.0625". The gap is that extra 0.0005.

But has absolutely no error effect if the needed rotation is less than one turn or 1/16th inch. If truly woodworking in thousanths of inches, it would be easy to add (or subtract) .0005" to each rotation.

Let's see - if I had to rotate 4 turns the error would measure to be .0005 X 4, or .0020". Eight rotations would amount to .004" That is no error in my mind. Also in my wood,- or project.

Any 'error' is far less than the inaccuracy of 'reading' from the indices over that gap between the collars.

We be jabbering about the scale 'accuracy', not the thread pitch 'accuracy'!

Once a full revolution has taken place, any scale error is 'reset'. Only a thread pitch deviation is accumulative.

i.e. This is much ado about triviality.
