Stéphane, this is the part indeed.

To find by how much you have to trim it, you have to find the diameter of the pipe used. Indeed this pipe ID insterted inside the hole (that's why the part is trimmed, it is to enlarge the hole).

Im in vacation so I cant check, what I remember is that I used a standard Plastruct pipe (31.75mm or 1-1/4"). This diameter looked correct to me, the parts looked correctly spaced in it and the Sat part height looked OK so Im pretty sure the diameter is correct.

They indeed filled the small holes created with clay in order to be able to mold and cast it.
Red Jammer is the only one to use styrene kitparts then those holes are not

The Ladd Y is 99,9% castings (even the cockpit with the additionnal plating is a casting) so it has the filled parts.
 
About halfway done casting all the Tail Shrouds...

Looks like a photoshopped copy & paste job of one identical piece stacked into a pyramid! :lol Amazing job Dave what awesome quality!!! Thanks for posting so many in progress and update pictures!
 
Hi Dave,
I am very interested into this great build! It looks very professional so far!
In your posted video you have told that you have got high res photos of the original y-wing. Could you please tell me where I can get these pictures?
Many thanks!
Mark
 
NEW FILES UPLOADED TO THE REPOSITORY!



There is a new folder for the Tail Shroud Assembly in the Repository:

https://drive.google.com/folderview?id=0BwDa06cjX-frMy1mekJzNmx1NEE&usp=sharing

In it you will find the following files:

Tail Shroud Drawing - An orthographic drawing of the shroud assembly and it's component parts at 1:1 scale. This drawing can be used as a pattern to cut out some of the control vanes from styrene if you want to scratch build them.

STL file for the Tail Shroud - this is the same file I used to have the Shroud printed for molding and casting. You are welcome to print your own, although at $20 a pair my castings are probably a better deal.

STL files for the Control Vanes, Ring and Shocks - These can be used to 3D print parts. The price at Shapeways to print two sets of these parts in Extreme Detail Plastic is about $78. I'm currently working with an RPF member that may be casting these parts for about half that cost, So you might want to wait to see if that works out before springing for 3D printed parts. Of course, you can always buy 2 Sealab Kits on Ebay...

A STEP file of the Entire Tail Assembly - For anyone that want's to import the parts into a 3D modeling program and mess around with them.

Sooo.....
Here the V02 of the engine connector with fins. the main body being 31.75mm or 1-1/4" as precised by Dave and Julien. I did make the connector and fins to fit the trimmed Saturn Y large cone.

I did make a tool to make sure that the fins are perpendicular to the body. you should not need it bud just in case...
I've just send all the files to Master Dave so he can make them available on his open source account.

No support should be needed when printing.
If someone like Dave or Julien can tell me if I made it too long... .


Hope it helps.

Looks awesome!

This is coming from my phone, expect errors.
 
Dave: is it possible to get orthographic views that we can print out full size? I have only had the fuselage printed so far because I noticed a kit part not fitting. In doing this, we'd be able to test out the dimensions before we do any other work to change them in 3D.

These orthographic views would help me very much, but I don't know how to manipulate the 3D model info in order to make them.

The problem, with the hurricane engine blocks being half a cylinder over the edge of the wings, might not be to just make the wing leading edge forward further if that change make another part of the fuselage too small to fit other parts.

I've also noticed the yoke piece that fits on the bottom might be a little narrow to fit the 25 pounder piece that goes there. And on the original, it has a notch in it as shown in this pic:
This image I think answers the tee bar question , if this is not a pyro then these where definitely plastic, also I seem to remember an interview with ILM who mentioned the filming crew were constantly breaking ypthe rear off the engines and they were always required on set to repair them, said film crew were heavy handed, I'd image brass would have bent not broken
 
For info Dave, when the cone are trimmed to reach the X under level, It measures 0.71 inch in eight on my two Saturn V cones. And they are old versions of the kit.

Stephane - Here's what I've got in my computer model for the trimmed Saturn cones. The trimmed part winds up being .758" tall. This is the minimum trim that would expose the full inside of the horseshoe shapped areas as it appears in the Ladd model. It looks like they then filled those areas with a bit of putty.

Steph - not surprised, the dimension I gave was based on the computer model of the part. I have yet to actually cut a cone. It's a pretty small difference considering that these parts were probably cut or sanded by hand back in the day.

Here's and interesting image of the Ys ready for paint. On the three nose down models the Tees are definitely brass colored, not the dark grey of the Plastruct ABS Tees. The nose up model looks to have been primed, You can't make out the Tees on the fifth model on top of the toolbox in the background.

Edit - something I just noticed is the TIE Interceptor wing in the background. So that would make this photo from ROTJ. But there is a photo of Dave Beasley working on the original ANH Y and the Tees are brass.

It's definately possible they used both as I've seen some images of the MOM Y where you can clearly see where the T bar has been broken and then glued back together.
 
I was planning to do them Brass and the only size I've found are matching the 3/16 inch Ts.... (T6)
I did not find yet anything close to the 1/4 inch Ts (T7). They are not doing them any more. I've asked them if they were planning to re introduce the 1/4 inch Ts and the answer was a strong No. :(

By the way, I do not remember ever seeing this photo of those Y-wings waiting to be painted. Thanks for that.
And what the F is that huge Y-wing on the right corner??? I knew they did a big X -wing but I've never seen a giant Y-wing like this before.

Exactly how I did cut and sand my Saturn V cones. By hand like the in good old times. ;)
I was just providing that measurement just in case you wanted to adjust your 3D model. :)
