Fixing cracks in a fibreglass spinner

[Triton II]

My little Airtourer aircraft has a 12-1/16" diameter by 13-1/4" depth fibreglass spinner. It has developed cracks over the years and I'd love to find out how viable it could be to repair it, as a new one is $924! Ouch. Any help from fibreglassing gurus appreciated...

Huh?? Whazzat? Is there another name for it that we might recognize?

Years ago i had a friend with a kit airplane. We used his spinner as a mold to make a mold and a new spinner with polyester resin. If we could do that I don't see why one could not be repaired. Would like to see some pictures before offering any suggestions.

JB, the spinner is the nose cone over an airplane prop.

Since the part is not stressed and load bearing, no reason you can not repair it. then again, follow what George stated, and make one by making a mold of your current one, you can even make one out of carbon fiber and epoxy

I would also look around. aircraftspruce has 12" spinners for $227

I must have known that when I was in high school. I worked as a gopher at the local airport and got paid in lessons.

Thanks for the memory jog, Scott.

Thanks for the replies, I've managed to source a new one here in Oz for $270 so problem solved! Thanks again,

That's probably the smart move. The spinner may not be load bearing but I still wouldn't want to unbalance it with adhesive or whatever else one might be tempted to use.
