Source for 13" Spinner

[whee]

I need 13" spinner that will fit a McCauley propeller. I see that Glenn bought one from Vans but it won't work with a Mac. Anyone know where I can find one? I'm not real keen on using a Cessna spinner.

I've heard nothing but good about these:

Thanks, I'll check them out.

Aren't Bob's spinners 13 inches? He has one in carbon fiber and one in fiberglass.

Help me here; after reading your response, I started looking for Bob's spinners. I'm afraid that I'm not enough of a sleuth to find them. I, too, might need a spinner. Could you post a link to info, re: Bob's spinners?

Thanks, Bill

I can't find one in fiberglass.

I have an extra 13 inch fiberglass spinner. Bought it years ago with an AeroComposite prop (which used a McCauley hub). Since have replaced the AeroComposite on my RV-7.

I just caught your posting on your quest for a MacCauley C203 spinner. We gave up looking for one and were fortunate to find a spinner with backing plate for a Cessna 180 locally. I was under the mistaken impression one could be bought & installed. The AeroComposite may fit.

The backing plate & spinner are unique to the C203. There are plastic rings and a plastic cone that go on to the front cylindrical projection to stabilizer the spinner. The backing plate is mounted using lugs captured by the prop bolts and the backing plate is held by screws through the lugs. The spinner is pushed on really hard until the screw holes match between spinner & backing plate. The plastic cone has rings that can shim the cone outward to get the spinner tight. Apparently if the spinner is not a tight fit then it will eventually fly off. Check with maintenance facilities service primarily bush planes and people who fly them for their business. Our spinner came from a company that flew 180s to deliver equipment & services to remote locations. We needed different lugs and exchanged the ones we bought with a maintenance shop for the ones we needed.

I borrowed these examples from Skywagon City that sells used Cessna 180, 182 & 185 parts. This is a set that would fit http://skywagoncity.com/index.php/sp...0-spinner-kit/ except your hub & prop will need 6 triangular lugs similar to these http://skywagoncity.com/index.php/sp...bulkhead-lugs/ . There are two styles of lugs. The longer lugs have the wrong offset between the the hub bolts and the backing plate attach points. We traded out for 6 smaller lugs. Your dollar is in your favor as Skywagon City is Canadian & a good company to work with. We have bought parts & a transponder from Skywagon.

If you can get part numbers then that may assist in your search. We paid about $600 for spinner, backing plate and parts. If you can find the right source then you may get the parts reasonable.

Thanks Glenn. I think I will be able to make the AeoComposite spinner work. I'll need to adapt the backing plate but it appears that it will be pretty easy to do.

Perhaps the AeroComposite is a straight forward install. I bought the Van's Spinner as it is used by other builders & it was not easy work. It required modifying the steady plate that went into the upper cone to secure the spinner . It would have meant more work & ingenuity to fit it up than we needed. If the Van's spinner was modified & passed a point of no return then the risk is that it would have been a loss.

Once the Cessna assembly was found it was a relief as it meant no work except paint. The Cessna backing flange is dished forward & flanged backwards that gave the clearance required. The back edge of the spinner flange lined up with the back of the engine flange. The Cessna spinner eliminated the work of cutting the prop openings, installing nut plates, developing & installing the upper steadying ring.

The Cessna backing flange is substantial construction with thick plate & laminated layers of aluminum. The flange has the ears that go behind the blade to wrap the engine side of the prop hole & the assembly is a clean fit with the spinner. The spinner assembly mounted with no work for fit up and is a proven system. It was worth it to have the peace of mind & not spend the hours to make a piece to duplicate the OEM spinner. The Cessna spinner was better construction.
