Vintage Mooney Cowling Mod

[Browncbr1]

Just spent some time with Catto Propeller talking spinners. I may have a way to solve the high price spinner by having carbon fiber spinners made.

If that's the case, you've got to come up with natural carbon finish!

[bradp]

Just need a good way of electrically insulating the carbon fiber from the important bits.

Would there be a way to avoid pulling the prop ??  or would there be no way to avoid that labor and re-balancing?

[flyntgr1]

I would guess if you already have the 201 spinner bulkhead mounted, then you could get away without removing it.

[Sabremech]

Hi Flyntgr1,

That is correct. If you have the old style spinner and backing plate, then the prop would need to be removed to change the backing plates out.

Thanks,

David

David,

Have you checked with www.tcbcomposite.com

They have quite a few models as well as manufacturing capabilities.

I know I had asked before, but do you think you will be making the cowl work with non-201 spinners? Really, that's the only reason I don't already have the swta cowl. The cost of new spinner and backplate, plus removing the prop and doing another dynamic balance. Not to mention new motor mounts, as I understand that is advisable when setting up a new cowl. It all added up to too much.

Hi Clarence,

I did check with TCB and didn't find the diameter that I need for my mod.

Hi Browncbr1,

I've looked at it a little and I don't think I can work the round inlets in and I know I can't get the air filter in the left cylinder air inlet without the cowl moved forward a bit. It could be done if I made a whole new cowling but the air filter would have to remain where it is. I'll look at it some more when I get further along in the current mod.

Thank you,

David

Check with cumming spinners. Their aluminum spinners are very reasonable.

[Sabremech]

Hi N601RX,

I looked at Cummins Spinners and they look great. I'm hesitant to use a company outside of the U.S. other than Canada. It complicates the whole FAA certification process.

Thank you,

David

An unpainted carbon fiber spinner would look ausome

[Sabremech]

Time for final fitting of the new cowling pieces, then on to riveting the parts together.

David

[Guitarmaster]

That looks AWESOME!

David,

Did you see somebody mention (today in another thread) something about updating a Rocket's cowl...?

Just connecting some threads...

Keep up the good work

[Sabremech]

Hi carusoam,

I didn't see that. Is someone looking to make anew cowl for the Rocket?

Thanks,

David

[Hank]

Oh, WOW!!!!

[carusoam]

David,

It was a question coming from a new MSer...

Hi carusoam,

I went looking and found the thread. It could be done and I might look at it when I'm done with all the vintage models. It's not easy but challenging and rewarding when a prototype is close to being finished.

Thanks,

David

Yah. Leave the man alone. We want our vintage cowls brought into this century.

Oh my gosh!  You are an engineering artist!  I had not been following this thread! Mine too please!  I am sure the J's....and the K's would love an update too....

 

I know I would!  Although a bit more complicated because for a rocket the original K-cowl almost fits, except for a minor bump near the front left for a cylinder.

I'm loving this and have been watching for a while. Only thing I'm a little confused on is the spinner. I have the hartzell top prop on my C with the long pointed spinner. Will this work with your cowling? I know it's a topic that's been brought up before but most of the conversation was on the later model OEM spinner and I'm not familiar enough to know the difference.

[Sabremech]

That's a good question. It will depend on a couple of things, what is the diameter of your spinner at the base and where is it mounted on the propeller? I'll try to post a picture of my spinner backing plate installation and the diameter of the 201 spinner is 14 inches.

Thank you,

David

[StinkBug]

I'll try to remember to measure and take some pics when I'm at the airport tomorrow

[Marauder]

David -- I apologize for not following this closer. What are the target planes for this mod and will it work with planes that have been modified with the 201 windshield?

Hi Cliffy,

I'll include the D. It might not be in the first STC just like the pre 66 airplanes, but I do plan on doing an STC for the 65 and older birds. There's a cowling set on EBay right now I'm contemplating buying for the early planes at a reasonable price. I think I get them for the future mod. It will work with the three blade prop with the correct part number spinner. I'll work more on specifics of that later on in the mod.

David

I'm also interested in this bit. I'm looking at a '63 M20D with a 3-blade Hartzell and a cowling might be the first major mod, I think,
