Official FMS 1500mm P-47D Razorback Thread

Elbee,Do you feel a 3d printed hub would be strong enough to withstand the stress of a spinning propellor. It's a concern to me that it doesn't cause an accident to someone. Hesitant to have a HS class be put in that position.Best Regards, Rex

Rex,

The simple answer is no......but.....

The centrifugal forces are fierce at the prop hub under load.

That on record, nothing beats a failure than a try.

Print wise, I think it can be done as long as the hub is simply eye candy and the mechanical structure (for lack of a better term) is solid.

I thought about trying something similar with the Corsair as the prop is rather large.

The loads even in twist would be great as the prop bites under force.

Your machining skills could come into play here, you could design a four way with center hub to fit the shaft.

The hub shape would be a 'skin' the looked correct but carried no real loads.

That was my approach only I was thinking about printing something in nylon instead of machining an aluminum part.

I do not have a lathe, but wish I did.

Using a combo of nylon print and fine machine screws, I might still give it a go one day.

The other issue would be the total mass of the hub, but it is close to the center of motion, hey I am not an engineer and cannot play one here.

Thanks, Elbee. I thought of machining a 2- piece hub to bolt the props as in the original but feel the weight would be excessive for a foam aircraft. I can live with the prop hub as designed. Finished the first alum. spinner today. I have a few ideas to lighten it more.
You would like a lathe and mill - so much can be built with them. I still want a prusa mini, I just haven't made that leap. What other tooling would I need after buying a prusa? Enclosures, drying, etc.? Like owning a lathe there is tooling to buy to really get all the benefits. I keep reading info and it's like another world too me.

Rex,

An enclosure is a good idea.

Prusa has an new enclosure, but why spend that kind of money.

There are parts to print online to build what's called a Lack Enclosure.

Prusa came up with the idea about the time I bought my Mk3.

It is basically two IKEA Lack model end tables where you use the base of one and the printed parts and the entire other end table.

The second project I printed on my printer was the added parts required to build it.

You'd need some plexiglass sheet (Lowes) and some LED lights (Amazon) if you do what I did.

Doors in the front and lights above.

If you bought a Mini, there'd room inside the enclosure to store a roll or two of filament and your tools.

Let me know at that point and I'll find the article and/or send pics as needed.

Best, LB

Today I made a little more progress on this project. I added the taillight lens, made with clear epoxy, I drilled a .043" dia. hole in the center, and it leaves an impression like a little light bulb. Added the landing light lens and flange cover, will need some paint touch-up after drying. then I took the alum spinner hub and placed it on the original prop and prop stud. It looks large but this is a smaller prop than the vs3 Corsair prop so it should look ok. HS class is using my vs3 prop to design the cuffs at school.

Best Regards, Rex

very nice. can I please get a link for the light and lens cover?

If your talking about the tail light, I made it with clear epoxy from my wife's craft epoxy (epoxy can be found in Jo-Anns, craft stores) If it's the landing light. I made a half hole in the wing, placed some alum. tape over it and used a broom handle to press into the hole. Took some time to mold the tape so it formed to the hole. The light bulb is from a 1/16" plastic rod about 1/2" long pushed into the center with 1/16" protruding. The Lense is a 1" Googley Eye from Walmart. Dis-assembled and glued in the wing. a styrene .010" flange cover was cut out and glued. I hope this answers your question.

Best Regards, Rex

Really coming along Rex!
I like the nose cone, looks very authentic!
Twisting my arm to get a P47! I was hoping for something from Flight Line, but with Alpha gone, it seems as if that the end of the 1600 mm single engine warbirds. Someone please correct me if I'm wrong!

[jetfool]

Thanks, Grossman56.
I'd like to see FL introduce a new warbird too. SBD, Hellcat, Zero, P-47, anything at this point. Probably cost an arm and leg this year, but OH WELL!
The FMS p-47 is really nice, right up there in my FL Corsair quality. Price is reasonable,$379
Hope you get one, Dave and I are having some design work done for the P-47. Alum. or 3D spinner, Prop cuffs for a Curtiss prop. If all goes well we at least can print our own parts. I will know more on how the HS class is progressing on these designs later this month. In the meantime you can place your P-47 order. LOL
I received Callies Graphics and started applying. Can't believe how a different paint scheme has changed this plane.

Best Regards, Rex

Hey Rex, here's something that may interest you:

[jetfool]

WOW, Dan. I 'm just getting ready to finish the cockpit and now you have put a complete stop to it. LOL
This 3D cockpit looks like a better scale version than the OEM. Price is ok and it can be scaled from 1/4 to any scale. I will probably order. Has Dave seen this and does he think it would fit into the cockpit space without too many mods.? The lower OEM cockpit would need to be lowered. I think there is enough room, will just have to measure and see. Thanks for pointing this site out. You're making me do more head scratching!
You do know I'd have to make the canopy in the open position to show-off all the detail. DETAILS, DETAILS, ARGHH

Best Regards, Rex

[Grossman56]

The cockpit of the Spitfire is finished, all I have to do is glue the canopy back on. I was saying to myself, "What a difference detailing the cockpit makes" Same with the Corsair. Now I'm getting Dave to print up another RAF pilot, this time with the O2 mask on, but the goggles still up, for my BBD P51D. I designed a throttle quadrant that we've been playing around with for all the Mustangs in the Stable as well. I think I've drank from the cool aid of detailing. Was just watching a video on the P40B that survived Pearl Harbor and drinking in all the details of the cockpit. Yep, I'm addicted!!

It's just the knowing, right, that there's something else going on under the hood.

Congrats, Danger, on a job well done.

[jetfool]

Grossman,
Glad to see you too are enjoying your airplane adventures. You should have a pretty good airforce come spring
Best Regards, Rex

[jetfool]

It has been a little slow lately, cold, cold temps and watching too much TV shows.
I have been applying Callies graphics and nomenclature and looking for a better nomenclature placement sheet. The ones I have do not show all the placement information. Could someone post a better schematic?
The graphics are going on great but I did make a goof on the letter P. Pulled the paint down to the poly so I will need to repaint this aera and order a new graphic. Overall, this is really looking nice from where I stand.

Best Regards, Rex

She is really coming together, Rex.

Shame about the Boo-boo, but we've all been there.

Again, great work, Sir.

Best, Steve

[jetfool]

Elbee,
At the time I grit my teeth over a boo-boo but making mistakes helps me learn to do it better. A little paint, new graphic and it will look like new.
The new paint job has really made this plane come alive and look bigger. The OEM is outstanding but in my minds eye this really is a battle tested P-47. After more detailing/worn look I will be pleased.

Best Regards, Rex

[Elbee]

You probably do this, but I mist a little water on the area I am laying the graphic, especially the larger ones.

[jetfool]

Elbee,

I was using water to fix in place. afterwards I moved it out of the cradle to work on the wing and didn't realize I disturbed the graphic. Should have just quit for the night, live and learn! LOL
Your B-25 is coming together nicely.

Best Regards, Rex

[f4u ausie]

Looks absolutely beautiful jetfool.... Love the Matt finish
So many nice schemes available for a p47..

[jetfool]

F4uausie,
Thank you.
I like the matte finish also. I think I will give it a very slight dirty wash on the whole airframe to help blend graphics and paint together. I am afraid if I clear coat with poly-Cyrillic it will take the dullness out and become shiny which I'm not looking for. A subtle dirty wash will take that new airplane look away also. Make sense

[f4u ausie]

Absolutely
