OK so I'm strugling to find out what folding prop I need
The model is a hollein introduction glider 2.860 wing & 920g flying weight
I've got a overlander tornado thumper 2826/09 motor
With a 30a esc with Bec and a 1300mah 11.1 3s battery
These aren't the recommended gear but what I was told in shop would be OK.
Also the motor has a 3mm shaft would a 3.2mm or a 3.1mm be too big to clamp down ??

I'm afraid you've had bad advice on the motor. The KV is too high, meaning it would be limited to using a prop too small for a decent climb rate with this model. IMO a heavier motor with smaller (lighter} 3s lipo would be a more suitable combo.
I intend using one of these Keda motors with a 3s 900 mAH lipo when I build the Introduction. My Amigo 2 glider is powered by the 1050kv version of the same Keda motor driving a 9x5 prop. I could use a larger dia prop for faster climb rate but as the Amigo is a vintage glider I'm satisfied with the slower but still fairly brisk climb rate.
A 3.1mm/3.2mm can't be used with a 3mm shaft.

Completely agree, the KV is far too high.
Personally I would be looking for a motor in the 1000 to 1250 Kv range producing 250 to 300 watts on a 3s battery. You will need to know the max diameter that will fit in the fuselage, my guess is a 2826 or 2834 might fit.
Once you have your motor sorted, choose the correct spinner/yoke/prop blade configuration from the Aeronaut range.
Hyperflight recommend the following power systems for this glider.

A 3.175 prop adaptor might seem as though it clamps onto a 3mm shaft but it won't hold and will not stop the prop flying off dangerously.
Lets hope the motor ordered has a shaft that suits the prop adaptor.
