I say that I’m not a builder but propellers seem to be one area where I put knife to plastic on a regular basis. I “redid” the early and later Rotol props. I used the same basic method that I used a few years ago for an Me-109E build.
You drill a small hole in the blade and insert a length of ordinary household sewing pin, cut to size with some wire cutters. I put a drop of super glue on the pin.
I drill holes in the hub…
…and glue the pin in the blade into the hole. The metal “shaft” makes the assembly strong.
I didn’t like the blades on the two “homemade” props so I replaced them. The later Rotol prop got some longer blades from the old Revell Hurricane prop.
It looks like this when installed.
Much better. Not perfect, but better.
The early Rotol uses the blades from the Hasegawa kit.
Of course, the Hasegawa blades are odd looking. A little too Klingon. But I think I’ll let that pass.
One of the reasons I fool around with propellers so much is that they MUST SPIN. I want every model I make with a propeller to have a SPINNING propeller. This is not easy.
I also decided to use my homemade de Havilland prop on the old, old Revell kit. I’m thinking maybe an early Sea Hurricane? (I say! It’s not a “Sea” Hurricun, old boy!)
I’m having fun. I could have just sent off for some Quickboost propellers, but where’s the FUN?
