Default APC prop to GWS 400 4mm shaft ??

Need help installing APC props to 4mm shaft. The adapters I've found are designed for 3mm nut ( GWS 350 shafts ). Anyone found a method ? Thanks

A small piece of fuel line and 2 washers will do the trick. Place one washer on the shaft followed by the the fuel line, then the other washer. Tighten the nut and the fuel line will expand and hold the prop centered and in place. You need about 1/8 inch of fuel line to extend out from the prop before you tighten the nut.

This is what I did on my Tiger Moth 400 and it works like a charm. If the prop wants to spin use a longer piece of fuel line.
