GOOD NEWS!!!
The bushings finally arrived!
The envelope looks like it's been dragged through a war. Mailed on Dec 18 and arrived on Jan 14, now that's service!

Looks like it got delivered by Ace Ventura, if you get the movie connection!

and it only cost $5.90 USD. Bargain, huh?

Davegee,

That is what I will try to do when I get to detailing the engine. Yours look real.

Best Regards, Rex

Thanks, I have done a TON of these R2800 wiring harnesses! Any questions, let me know.

You can see what the Corsair V3 prop looks like on this airplane. The differences are distinct and impressive when compared to the OEM prop from FMS. Still, I think doing your initial maiden and testing with the plane is good to do with the OEM prop, which I think you said you were going to do. Then you'll be ready for the bigger prop, which is not a big deal.

Best,

Davegee

photocopying the back row is a stoke of genius, but no, I printed 3 separate parts: a thin back section, center section and front section.

Glued those together with thin CA.

I painted parts as needed for assembly and then added the plug wire detail.

The tricky part was cutting back the foam to accommodate the depth of the P&W Model.

I had to cut back the motor mount and design a stiffener to reinforce the mount to the foam.

This had to stay square to the world while not change the thrust angles built into the OEM design.

This might have been over-kill as they say, but for me, I was in uncharted lands and wanted all to be solid.

In the end, it all worked out and was worth the effort, I think.

I have been using the technique of photo copying the OEM cylinders for many years and then cut to fit paper copies in the gaps to give the impression of cylinders behind and in between the front row of 9 cylinders. Regarding the wiring harness for this engine, there were several different types and colors of them around the crankcase, but in all instances, at each point where a sparkplug wire comes out of the harness, it is paired with another wire that goes over the top of the cylinder and attaches to the other sparkplug (made to look like that for these models) on the back of each cylinder head. Ends up being a lot of wires but it looks pretty cool, even for a foamie. That's just my take on how I do them. Ignition wires varied from black to silver to gold, and probably others, too. Here is what I did with my FMS P-47D Penrod and Sam. The Corsair, Hellcat, and P-47 all used the same R2800 P&W engine, so they are all pretty similar.

Wow, looks fantastic.

Some reference pix for your P&W R2800 painting.

[Grossman56]

I recall, the work you put in is almost as difficult as restoring the real thing!
Dave came up with the idea of taking a picture adjusting it to size (which was very simple in Adobe Elements) and cocking the picture one cylinder over and gluing it in. Once in position, a bit of carving on the paper, which ends up looking like an inner tube, and there's your back row of cylinders.
Reassembled the old girl to see how 'salty' she looked. A couple of palm trees in the back and she's good.


My salty marine!

Looks Great!
Did you photo copy the back cylinders or was that a 3D print as well?

At any rate, the result is very realistic.

...This might sound crazy, but is it possible to create an STL file for the wiring harness for the Corsair? Seems to my that would be on everyone's list.Grossman56(Dangerous Dan)

DG,

I purchased STLs for a P&W 2800 engine, don't remember where, but I will look if you want.

In the 1:1 the way I understand the plug wiring is inside the ring and exits for each cylinder.

Point is I used bent aluminum wire and shrink tubing to simulate the wiring harness.

See pics.

Picked up some paint and materials today and got at it again. Did the aging on the prop, it looks wicked!

Started in on the motor upgrading (painting) as well.


Have to dig up some wire and start on a harness as well. I'll use this pic to try and photo copy a rear set of cylinders.

BTW, I watched some vids on resin printers. HOLY CR*P!! it looks like something out of Star Trek where they create the Borg!
Just too bazaar!!

Grossman56

Good work on that prop! It looks like something that was exposed to the elements in the Pacific Theater for a while!

Resin printing is a definite consideration for 3D printing. Elbee has one, and I have several friends who have them, too. I think I'll get one in time. You can get some extremely smooth prints for certain work. As Elbee said above, it has some drawbacks for modelers like brittleness and weight.

Cheers

[Grossman56]

Thanks Elbee, just took your advice and downloaded the Prussa slicing program. Give me something to learn, keep the old geriatric brain functioning. As for the slicer, I was quite surprised at how reasonable the price was. Now to convince 'She who exceeds my rank' to think in the same vein
Meanwhile, I'm feeding Dave all the STL's. Just purchased to pilot bust for us and sent the file you forwarded to me for the Spitty cockpit. This sure has put new joy in modeling for me.

Danger,

Your detail work is simply great and quite realistic.

As for resin printers, don't over look the versatility of FDM Additive Manufacturing aka filament printers

Yes, Resin Prints are outstanding and the parts look top notch, but the material is inherently brittle, read, non-structural.

I could not have done the all of the mods to my Corsair with resin printed parts.

Detail parts, yes, such as the pilot's head and side panel skins, IP, but not the cowl flaps or sliding canopy parts, strut covers, etc.

Additionally, resin parts can be heavier if the parts have mass, like a pilot body.

There is realistic limit to thickness of the outer shell, typically 2mm, so depending the size, the weight penalties can be prohibitive.

There is place for both in this hobby, IMHO, and filament printing is cleaner and more cost-effective.

I did just receive a resin printer from Santa on Christmas morning and I am looking forward to printing some detail parts for my Desert Warrior B-25C.

I will post pictures when I get there, currently waiting on Amazon to deliver a new surge protector power strip (tomorrow).

Reviews will be welcome.

Best, LB

Davegee,

I spoke with the industrial arts teacher Sunday at our indoor fly. You need to send me a hub with inst. on what you need modified and the class will be happy to design a new hub. He said they would measure everything and add modifications. We would have the STL for future needs.

Best Regards, Rex

Sounds great, Rex! Can you PM me your mailing address? I'll send a complete hub, inner and outer parts, a Robart tire and instructions as to what the problem is. Should be an interesting project for the kids. If possible, once we have a solution, I'd like to have or buy the STL as I will probably have to print out several of these in the future, assuming we are able to address the problem with these wheels/tires combination. I'll report back to the kids the success or failure of this new design this spring, or whenever weather is good enough in these parts to do some testing of the hypothesis.

Thanks so much!

Davegee

You two are having too much fun. Great to see fixing up hanger birds. Make a fiberglass door and sliding canopy, come on guys What's the Problem? Experiment!

[davegee]

I did some digging through the spitfire thread to see what Elbee did way back when. Ended up using the AOI pilot and the Motion R/C 3D printed pieces, which they removed from the website for some reason. Now, if Elbee still has the files, maybe we can get him to forward them.
I was thinking that the bust would be the easiest way to go, better looking pilot than the AOI. I've seen where guys have modified the fuse so that the door opens up. If I were to go the full pilot route, then making the door open would make sense, but then you have to have a sliding canopy. Easier just to do the bust mods and still visually pleasing with minimum cutting.
BTW, Elbee's cockpit green is deadly and so is the strap connector!

Grossman56
(Dangerous Dan)

I agree, Dan. My Spittie is now approaching 8 years old. A little "weather beaten" but looks like a fighter!. I'd like to do the cockpit mod and I'm all for using the Grueter bust for our pilots. They would look and fit the best, I think, once I get them in the proper scale to print, which shouldn't be a problem. If you want to order the Grueter files, I'll be happy to print up a pilot for you, and do one for me, too, while I'm about it. Once we have the files,we can print as many as we need for this or any future projects using RAF pilots. The pilot of mine, Witold "Lanny" Lanowski was a Polish pilot, a fearsome fighter, and eventually came over to the 56th FG to fly P-47s until the end of the war.

Cheers

Davegee
