Trumpeter P-47D Razorback

[crazypoet]

@DocRob I did a bit of digging around.  I found one maker who *did* 1/32 scale hose and line fittings, but they are sadly no longer in production.  Based on this one find, I’m betting there are others.

for this particular line I’d need .4mm (plain) and .6mm (flex) fittings. Some of the internal feed lines would work in .8mm, but that would be way too large for this.  I’m using .3mm wire and .5mm braided line stretched over the .3mm wire, and that seems to be working size-wise.  Absent actual scale fittings, I’ll be painting those in, with maybe some drops of CA that I can sand/file to shape

that said, you certainly got me thinking, and I’ll see if I can dig up some of the fittings in all sizes before I start gluing things down 🙏🙏🙏

I appreciate the feedback - that’s part of what I love about this place 🙏💯🙏

A quick update on this 

as I’ve been sort of obsessing over the landing gear and associated plumbing, I’ve found some interesting “headaches” with both the kit plastic and aftermarket metal gear struts.

these are things that could have been easily fixed - especially in the aftermarket struts, but such is life 🤣

I’m actually a bit surprised that Eduard didn’t include some of these fixes in their otherwise excellent exterior detail set 🤷‍♂️

ordinarily I’d take these in stride as just the pitfalls of working with the kit as it is.  But I’m also trying to be respectful of the subject and make it as “right” as my skills allow

so, first and most “obvious” are the oleo scissors.  The detail on the edges is fine, but they completely screwed up the most visible faces.

every version of these I’ve seen in both original and restored examples show that the scissors were made as light and thin as possible, thinned down and drilled to make them both light and strong.  This would be a very simple fix in resin (or if I had the mad CAD skillz and 3D printer access of some of our esteemed colleagues here).  As it sits, I’m left to figure out if my own skills with a dremel, micro chisels, and drills are up to the challenge, especially as both external faces of both scissors need to be identical as they’re really quite visible.  I’ll give this a shot on a spare set I have lying around, and post my success or failure for all to see 😂😎🤦‍♂️

next are what appear to be hub braces that help to align and strengthen the connection between the gear strut and the fixed inner hub.  Again, these are quite visible in both original and restored examples.  These I can scratch out of a bit of evergreen, but it irks me a bit that none of the aftermarket folk though to fix this

last, the relative spacing of the gear cover connections, oleo scissors, and uplock lug are waayy off.  Visually, this is fine - unless one is trying to properly route the brake lines 😂🤷‍♂️🤦‍♂️

as it is, both Trumpeter and the aftermarket metal gear struts made this space so tight (about two scale inches too short) that it’s a bit challenging to properly route the hydraulic line for the brakes and have it fit properly.

oh well, part of this hobby is overcoming exactly these kinds of challenges 🤣

I did figure out a different approach to the brake lines themselves that will allow me to build and use period-proper hose clamps, that I’ll scratch from thin brass and some .5mm OD tubing I found in my stash.

so.  That’s my rant for the day - photos of progress to follow as I figure out what I can/cannot fix, and get these things done so I can move on.

Î have some pics from a P-47D, I made in Chino some years ago. Hope they might help.

I just saw this thread. Extremely nice work going on here and very inspirational. Any more progress on this build?

 

Thanks,

Reuben

That actually does help - and looks amazing, by the way 🙏

it’s close to where I’ve landed with my approach 

[crazypoet]

I don’t get much bench time the last two weeks, as my girlfriend’s son was out of school and decided he wanted to hang out with me instead of his grandma while my girlfriend was at work (I think because grandma makes him do more chores than I do 🤣)

that said, I have made *some* progress 

I settled on my approach for the clamps and fittings, and have those ready to start glueing down

the fittings for the rigid hydraulic line down each strut are two pieces each - one formed from thin brass sheet and the second a short length of .5mm brass tube

i drilled .5mm holes in the sheet, then cut and filed each piece down to 1/32 x 3/64”, and put a bend in to give me a glueing surface for the strut.

the tube is cut to 1/16” pieces, which I’ll glue into place once the first bit is attached 

once all the fittings are in, the struts primed and the first layer of color and clear coat applied, I’ll run the .3mm wire and .5mm braided line sections

right now, the individual drilled pieces are threaded onto a length of tubing so I don’t lose them 🤣 ditto the bits of tubing - those are threaded onto .3mm wire for the moment

i also made the clamps where the flexible lines attach to the oleo scissors from a bit of foil and CA, and glued those onto short lengths of .5mm braided line, which I’ll cut to length when I install them.

this is as far as I’ve gotten with the time I had over the last two weeks; I’ll get to gluing things together this week, and hopefully get a coat of primer on before the weekend

.3mm wire and .5mm tubing/braided line are slightly small for scale (should be .4 and .6mm), but they look close enough.  I have .4mm wire, but not .6mm tubing for the fittings.  So to make everything actually work, I figured I’d rather be too small than too large

[crazypoet]

(Also, I still haven’t figured out whether I’m going to try to thin down and drill the oleo scissors themselves - I have an idea about how to approach it, but I really don’t know if my hands are steady enough to not turn them into mangled bits of plastic trash in the process🤣🤦‍♂️)

[crazypoet]

I took a short break from brake lines, and decided to go through with adjusting the oleo scissors (mostly because the handling required would probably bend or snap off the hose fittings if they were attached)

I discovered that my US-spec dremel doesn’t like working with a 220v step-down transformer, since it only puts out 9 amps.

soooo…. I used the same carbide bits that I’d have used with the dremel with just fingertips.  After a couple of tries on some spare struts, I’m giving it a go here

i have the basic form down, and the hole drilled.  Now I have to do a bit of final shaping, filling, and sanding to smooth things out.  Right now, it looks like a real hack-job up close, but things should smooth out with some careful sanding/filling/sanding and a bit of re-scribing the hinges

then, do the same three more times for the other scissor faces

its a right pain in the arse, but I think it will be worth it to fix a sort of in-yer-face error from the good folk at Trumpeter (which error was, of course, faithfully reproduced in the white metal set i picked up along the way)

 

 

[crazypoet]

Sooooo… 😂

this took a bit longer than I’d hoped, but I have the line fittings and hard lines fabricated and installed.  

Also, the oleo scissors are as good as I can get them within the bounds of my eyesight and fat fingers 🤷‍♂️😂🤦‍♂️

Getting the tiny bits of .5mm tubing joined up with the flat brass hose fittings was a right PITA, and I have a few small blobs of excess CA to clean up before I spray a coat of primer over the whole thing

I'm overall happy with the results, but I’m still cursing the lack of proper spacing between the oleos, up-lock lug, and the attachment points for the gear covers.  I made it work, but it’s a bit crowded in there 😂

this took a couple of failed attempts before I found the approach that worked, so I had to do some “error correction filler” spots on the struts.  Hopefully a layer of primer and remedial sanding will take care of those.

what can I say? It’s all a learning thing 😂🙏

so

here are some pics of one of the brass hose clamps, one of the short lengths of tube that forms the hose fittings, and a view of everything installed and waiting for primer 🤷‍♂️😎😵‍💫

once it’s primed and I’m happy, this will all be finished with Uschi’s steel powder, then a clear coat (which will tone down the powder finish a bit, which should make it “just right”), then washes, then the braided lines.  I’ll decide later whether I want to fix the connectors between the struts and gear covers, so they look like proper steel rods instead of plastic tabs.  That’s for next week, though 😂

Nice detail👍

One challenge is making the parts and another is not losing them in process.😃

I’ve spent more time than I care to admit crawling around the floor with a flashlight, after something *pinged* out of my tweezers  😂

YES!😄

Luckily we are not watchmakers🧐

[crazypoet]

Primer and first color down 😎

I used a mix of Alclad light and medium gray primers, thinned with Mr Surfacer 400 for the primer coat.

I’ve tested Uschi steel on black, and it looks good but it’s too dark for these, so I went *much* lighter in tone this time

i let the primer dry for about 90 minutes, then hit it with the Uschi steel powder, plus a bit of the iron powder here and there to deepen the tone a bit

tomorrow, once everything cures, I’ll do a clear coat.  It will likely dull some of the bright spots, but that’s not really an issue here.  If needed, I can do a light touch up before I start adding oil stains and suchlike

there is only a thin sliver of the oleo cylinder showing - I’ll hit that with some bright steel while I’m doing the rest of the details

i like the look so far!

[crazypoet]

Well, I have a *tiny* bit of progress to report - I’ve had almost zero real bench time the last couple of weeks, but I’ve gotten a *bit* done

The flexible lines for the oleos are done, and I’m fairly happy.  I cut the hose just a bit long, but it works.

this leaves just the flex hose that connects from the strut to the gear bay (which I’ll install just before I glue the struts to the wings), and the hard line connecting to the wheel hubs, which I’ll do when I paint and glue the wheels themselves.

I’ll create the fitting for the hubs with a bit of .5mm tube once I figure out the proper placement, then shape, trim, and connect the line after I glue the wheels to the struts. This will mean doing some minor adjustments to the shape of the hubs themselves - the barracuda resin wheels and tires are amazing, except for the detail on the strut side of the hubs, where the shape is just a bit off

Next up is to replace the molded plastic arms that connect the gear cover thingy (insert proper technical term here 🤣) to the struts with some 1/32” brass rod.  The plastic arms just look terrible, so this was an easy decision after about five minutes of staring at them.

I’ve done the measurements for both length and angle to match the kit bits, and got started with the first bit of cutting and drilling today (note to self - fill in the ejector pin holes and paint the thing *before* gluing the rods into place 🤦‍♂️🤣)

I’ve learned a lot about proper techniques through this process, which is fun in itself.  Several false starts and head-scratching to get to what actually works - but that’s all part of the process 💯😎🤦‍♂️🤣

 

[crazypoet]

Got the pins cut and glued to the struts

It’s easier to align from this side than it would have been to glue them to the gear cover first

The test-fit looked good (of course it will somehow be “off when I go to glue things together, because of course it will 🤣)

But I’ll take a deep breath anyway and prime/finish the pins in place while I finish cleaning up the ejection pin holes and get a color coat down on the covers

[crazypoet]

Just about ready to call this stage done.  

I have to put down the first layer of color on the outside of the gear covers, then these will be ready to attach to the wings (after attaching the wings to the fuselage, which I’ve so far put off doing)

I know that conventional wisdom would have me leaving the gear covers off until after gluing the struts to the wings, but with the way this particular bunch all goes together, it was *much* simpler to do all of this up-front.  If I need to do any fine-tuning to get everything properly aligned later, I’ll deal with it 😂

I now have to go back and face the reality of the gun bays 😬

 

[crazypoet]

Ohhhhkay

bugger

I’ve looked long and hard at both the Eduard and kit parts for the gun bays, and neither of them is going to really look “right”

at least not without a shitton of additional scratching and such.

so rather than going the way of madness, I’m going to just mount the guns and close things up.  Maybe drape an ammo belt somewhere

I’d hoped to have one of the bays open, but I just don’t like the results so far (I got a good start with the Eduard set, but the closer I look, the more I realize how much even *they* got wrong.  I get that they had to work within the limits of flat PE, but damn - they could have done a resin piece for the feed chutes that would have fixed pretty much everything 

so

oh well 😂🤷‍♂️🤦‍♂️

at least this will save me a month or two of heavy drinking and head-scratching, and get me along towards finishing this thing 😂

[crazypoet]

Ok, belay that last 😂🤦‍♂️

I’m going to do one open and one closed gun bay.

I’m going to wall off that part of my brain that’s screaming “but noooo…!” to a couple of the incorrect details in the Eduard gun bay set and just go for it as-is.

there was sufficient variation in actual field implementations that I can kinda justify the differences

I’m using these two photos as working references - you can see notable differences between the two (though they don’t, sadly, note which photo represents with variant of the P-47 they display)

you can see some of the different approaches even between these two pics - like stencils vs no stencils on the feed chutes, and different kinds of gun charger between the reference photo and what is included with the Eduard set.  The good news on the gun charger detail is that I *think* that the second photo shows a later version of the Jug, since the wing appears to be NMF rather than painted.  At least that’s my story and I’m sticking to it 😂

Sadly, the Eduard feed chute for gun #2 is simply wrong against *both* references, but I’ll bite the bullet and just use it as-is

the big question is whether I can make the rubber/vinyl/whatever ammo belts that came with the kit work with the Eduard chutes.  The Eduard ammo belts are kinda “nice try, but NO” for me 😂

The kit belts are much more accurate, but I have to be able to run them at least some of the way through the Eduard chutes to make the final assembly look right

hopefully, this won’t take more that one large bottle of rum to get me through all the cursing - wish me luck! 😎🙏😂

[crazypoet]

I dug up another good pic of the P-47 gun bay, still without any ID on the specific model.

this one has yet another gun-charging setup - looks electric in this one?  One of the pics I posted yesterday is either pneumatic or hydraulic 

on the other hand, the Eduard set has simple charging handles that connect somewhere behind the wing spar, which is fine, and that’s what I’ll use.

What is interesting to me is that this makes at least three different approaches to this on the same aircraft - I’d love to know the hows and whys behind all the changes.  So I have a new fun research project 🤣

this picture also shows some interesting clutter at the font of the bay, similar to what I is visible in one of the other pics from my last post.

there is what looks to be a structural steel rod and some hydraulic lines along the front of the bay, just above the gun barrels.  I need to look up what they connect to, and decide whether I want to include them in my build

one of the pics also shows some larger-diameter hoses that connect to metal fittings under each of the guns that look as if they connect to the ejection ports, maybe.

i have zero clue what they are, and (looking at how crowded things are going to be in there), I'm going to simply pretend that they don’t exist (or were specific to a later model 🤣)

[crazypoet]

Quick note to anyone who wants to do this kit in the future, with the Eduard Gun Bay set…

do *not* follow the Eduard instructions in step one about removing the rear mounting/alignment pin on the inboard gun.

you'll regret it later, when you need to add the same amount of material *back*, to get the guns to align properly during the installation 

ask me how I know 🤣🤦‍♂️🤣
