Hi Windz, Nice work so far! Just a question: which brand are your resin nozzles? And do they fit inside the plastic parts? S.

Hi, I've preorederd it, but it should arrive in late October... I don't know if that's the same out of France. S.

There are still errors, but I think I'll live with them. I worked on the pylon, the panel lines seem quite simple: A couple of things have yet to be corrected, but I should be able to combine my panel lines soon: To be continued (and I hope concluded) soon.

The profile of the lower part of the pylon was quite wrong. I'm trying to correct it. But each correction is the cause for a gazillion errors. Fun fun fun... S.

Just a test, as the panel lines are not that tidied up... It takes 10 seconds to get from last post to that one. Litterally. This method is awesome. S.

Now, I just have to tidy the panel lines here and there for them to have a constant-ish depth, and I can combine the two parts. S.

I unsloppied it a bit. So far, so good, and I really like this technique. To Nick : a big THANK YOU!

Yay, it works! Me likes! The bits inside the front ring are just me being sloppy, it'll disappear soon enough.

Thanks again. I'll try all that. S.

Thank you Nick, I understand now. But I can't do that on my model, I keep getting an error message. S.

It's good I lost everything I did since the first NACA scoop, then... Thanks! S.

Moving the stool: 1st method : I made various build planes, axis, lofts... 2nd method, which is simpler, but I think there is something even simpler around... I made a sketch on a plane I built from three points on the purple line above, made a sketch closely resembling the purple line, and went for a revolution. Not perfect, but hey... S.

I've done a NACA scoop, but I think I went the most complicated way possible. I'll try moving the stool and not the piano on the second one... S.

I stopped counting... S.

Five down, I don't want to know how many to go. It's quite a bit less entertaining than watching a grass growing marathon. S.

Oh, and I corrected the guide vanes in the intake, and created the pitot tube on the top center one.

Yes, I'm also a Tull fan. Sorry. First step for a panel line: a sketch that will be projected on the surface. Here, I made a straight line that crosses my nacelle from left to right. Then, I made a sketch with no drawing, just a projection along the Z axis on all the volumes created so far. Notice the purple line that goes around the nacelle. Then it's time to put the e-scribing tool to the e-plastic. I drew a 0.3 mm circle at the intersection between the purple line and the inner surface of the nacelle. And made a sweep of this profile along the purple line. The panel line is made. One down, quite a big number to go. S.

Nick, I'm afraid you've lost me there. S.

Oh, and a taste of things to come: S.

Here we are: So how did we get there? I re-re-did the rear, because the shape was quite wrong. The sections and the rails: And the generated body (loft using only first and last sections, and all the rails I could find). Then I went for the upper rearmostpart of the pylon. Sections and rails: Loft: Then it was time for the rear part of the pylon. And the trailing edge up to the rearmost part. The fillet had given me headaches. So I decided to try another way. First, triangle-ish shapes from the rear to the front, with a rail to guide the loft to come. And then, the final (I hope) loft for this project! Now, I can happily go scribing the surface detail. Once again, don't hesitate to ask questions, comment, criticize... If you think I got the shapes wrong, I'd rather you tell me now than when the parts are printed... Cheers, S.

It's getting better, but there are parts that still bug me.

As I wasn't satisfied with the base of the pylon (there's some kind of crease at the rear), I went back and redid it. I went with a rounded edge on the outer part of the nozzle "shroud". I then did a loft, which went totally librarian poo. I then redid a loft, but this time I only used front and rear sections, with rails intersecting each section. Now, let's work on the rear end... S.

Same process is applied to the nozzle (minus the detailing of the center bit). And there are 64 blades. Yes there are. Indeed. What about some panel lines? TBC, S.

I'll clean later... I drew the air intake profile, then made a revolution with it: I then drew the center cone (which isn' conical but hey). Another revolution, this time adding matter to the part: Then it was time for the boring part of adding detail to the front end of the not-conical cone : The J-57 on the B-52 D has six vanes protruding from the center cone. There goes the first one: And after a circular network: Now for the first stage blades. Let's draw the blade (in which good enough is good enough, perfection is just mistreating donkeys): And I decided there were 32 blades on the first row. Now, let's go detailing the smoky end. S.

The pylon is mostly done. I have some cleaning up of the surfaces left, but it should be bearable... I made the sections for the pylon lower two thirds and rails to link them for the eventual loft to be correct(-ish). Then I made a loft for all that. I made rails for the rearmost part of the pylon and two sketches for the upper and lower halves of the pylon. I didn't go for accuracy (well, even less than before anyway) as most of the rear will be inside the wing. And a couple of lofts later, I had my pylon. I still have some tweaking to do here and there, then I'll add intake and nozzle detail. Cheers, S.
