I don't really understand your problem but I'll try and help.

Here is how I tighten props.

Put the spinner backplate on . Put the prop on. Wind the propellor on (or push it depending how tight it is). You need to do this until the prop driver (the metal washer on the engine with the grooves on it), the spinner backplate and propellor are all in contact. Put your washer and prop nut on. wind this by hand until all are in contact. Hold the propellor in the correct position (top right blade in two o'clock position at the compression when viewed from the front).

Once there is a little pressure between the prop nut, washer, prop, spinner backplate and prop driver nothing will move. Now hold the propellor in your hand and tighten the nut with your spanner.

I hope this helps.
