Could you make a copy of the Holman drawing and write your correct dimensions on it?

You could scan it in a 2d printer and send me the scan or the picture (JEPG) via email or the Squawk.

Saves the postage and time.

This is the best image I have found that is square to the world.

Thanks Davegee, it was a very nice day, and our display was well received by the spectators. 5-6 people are interested in learning to fly R/C and joining our club.
Elbee, I used a very good 3-view I purchased from Bob Holman years ago. I blew it up to Davegee's specs., then started whitling alum. The radius was done by my eye and a cardboard template I made to check my work. I do know where you are going, and I can send you my original heavy spinner if you want to plot out graph lines of the radius. I will get the final dimensions after I make sure everything fits. A 3D printed spinner could be one piece and weigh lighter which would be the best choice.

Best Regards, Rex

Hope everyone doesn't mind seeing me trying to make a scale spinner. Trying to make it as lite-weight as possible. I can turn and bore on my lathe but the radius of the spinner I'll do with a file while turning in the lathe, a long tedious process. Some friends think I'm nuts for doing these things. Probably am! I have already lost 1 oz. of weight from my original alum. spinner. As you'll see in the pictures, I have a lot more metal to remove. I made a mandrel to match the motor threads and I can hold in the lathe to do finial shaping.
Please let me know if you want to see this or not.
Best Regards, Rex

Rex,

Do you have the 'lofts' for this or a decent side profile?

Do you have the offset for the an insert or nut measured from the propeller end?

Or so you know how you would want to attach the prop hub?

I designed an elongated spinner for y my Spittie that better suited the Mk19 Seafire and a smaller prop hub for my Corsair

You can see where I am going with this.

Let me know.

Best, LB

Thanks for the photos. Looks like it was a great day, weatherwise, and a great turnout, too. Your "Lucky" looks great in the photo. Can't wait to see it when you get it flying!

Cheers

Today we had a Static military aircraft display at our local American Legion. Around 300-400 people showed up to honor current and fallen veterans. Our display was mostly WW2 and Vietnam aircraft and helicopters. Many Vietnam Veterans came by and talked at length about their Phantom and Huey experience. Many harrowing stories were told, and I realized that these guys are mostly in there mid 70's and will be the next generation to pass in history. My Dad was the WW2 generation and most of them have passed.
Enclosed are some pictures before the event started

Thank you F4Uausie. I have always been interested in seeing how scale modelers-built things when I started modeling and just thought it might be interesting. A 3D printer is on my wish list but now I still do things the OLD fashion way. Keeps the ole' brain waves working
Best Regards, Rex

Rex,

I applaud you, Sir.

You want a 3DP printer and I want a lathe.

You are correct when you say all this modelling keeps the brainwaves humming.

Davegee,
I turned a center stud tonight, 10mm internal threads for the motor side and 1/2" external threads to screw inside the front of the spinner. Bored this stud out to keep it as lite as possible but enough strength to support the spinner. Going to turn another spinner and drill the inside out with 5/8-3/4" remaining in the nose. Thinking a 1/16" spinner wall thickness down to the solid nose will work. Fingers crossed.
If you're ok on waiting on returning your parts I will send a prototype spinner along with them for you to try out. The stud only weighs a few oz. so we might get lucky on total weight.
This Monday I have been asked to show a military aircraft static display at our American Legion for their Memorial Day honoring our veterans. Taking my P-47, FW-190, Corsair and Phantom. Hope to have pictures next week. Flying here has been a no-go, windy and rain.
Sounds like your father-in-law lived a good life and glad you had time to enjoy all his flying stories, sorry for your loss.
Best Regards, Rex

Thanks so much, Rex. He was a great man. Kinda ornery from time to time, but then, who isn't, especially when they're "north" of 100 years old??

I like your idea on the prop spinner. I can wait until you get the modified weight prototype done, and then I would be happy to fly it for testing. Whenever you get to that point, just send it in the mail and we'll test it out.

Good what you are doing for the American Legion and the display of your airplanes. I bet they will be a big hit. Memorial day is a very special day for me, too. My dad survived combat in WWII and Korea as a B-17, B-24, and B-29 pilot, only to lose his life in a B-47 Stratojet accident when it came apart in flight shortly after takeoff. But we remember Memorial Day for all our men and women lost during all our wars. It's fun to fire up the grill and all that, but still important to remember all those lost in service to our nation.

Let us know how the American Legion show goes!

Cheers

Guys I have installed the alum. spinner on my P-47. It really adds the scale appearance to the V2 FMS Corsair prop. I'm thinking to lighten it I will make a lighter outside spinner and make a stud that screws into the nose of the spinner and would then screw to the motor shaft. It would be 2 pieces but look like one piece when assembled. Davegee what are your thoughts? I might need to move the battery back a little on the battery tray to balance the C/G. Some pictures of my original alum. spinner.
Best Regards, Rex

Hi Rex: I'm really liking that spinner! My only concern is the weight, but if you can reduce it somewhat, hopefully we can use it. Because the battery bay is slanted down in the nose on that plastic strip where it locks in place, I don't know how you would move the battery back any if you had to compensate for the weight of the spinner. On a flat floor it would be easy to do that, but I'm hoping that you can reduce the weight of the spinner with your plan to make it in two parts that might do the trick and not mess with the CG too much.

Please keep us informed on this. I would definitely be interested in one of these for my "Ol' Cock" P-47 that had the Curtiss Electric prop!

Cheers

Dave

I think we gave ‘ol Fred a great sendoff, one we approached him with the idea of an overflight several years ago. Everything had to fall into place to pull it off, and it did. It was an absolutely perfect weather day to do this.

thanks for your condolences, f4uaussie.

Condolences also Dave.

It's a hard time

Beautiful tribute.

My sincerest condolences to you and yours.

Best, Steve

Thanks, Steve. He was 102 1/2 years old, so he lived a Very long and rich life. I don't think he had any regrets. It was a privilege having him as my father in law for almost 45 years.

Best,

Dave

Davegee,
