Here is a shot of the finished docking module ready to be attached permanently... The batteries in my cheap camera are about to die here, I put it in the freezer for 10 minutes just to get enough voltage to shoot these...

Just a quick update of a little progress on the docking module between working on the new masters for the better molds I have been working on for the front VTOL nacelle parts...

...Next before adding some metal tubing for the umbilicus connector up the front, I lightly sand with very fine grit paper along areas to give the module a better look, basically breaking up the uniformity of the surface... some would call it "weathering" i guess.. but here the primer allows a close color but its surface can be manipulated with different grades of sandpaper....

one only needs to pass the fine grit paper lightly over desired panels, the entire model will be sealed with a dull clearcoat..but thats way down the road

Here is a quick shot of the front engine VTOL thruster assembly I have been working on, almost ready for molding. The angle is dead-on accurate now, and I am adding extra piping on the part for accuracy and to save a small bit of labor for the builder. I will be molding this new part mid-week when my degasser arrives (hooray!) This new mod will be included in Freds kit, as well an new set will be sent out to the PROFESSOR free of charge...

and here is the top of the Docking module completed. I have added on all the extra "plumbing" that is barely visible in the movie...all references are available here on propsummit.com in the Nostromo discussion thread.

By now the module almost looks like it could be its own little ship, or motor pack type thing before it is actually attached to the Nostromo hull...

That's looking really great! I love your detail work. Is there a slight twist or warp in it - or is that just the photo (the little tab in front of the ridged section and the rearmost part of the seven-sided docking assembly each look slightly off-centre, suggesting the whole assembly is slightly twisted or rotated on top of the main module)?

Thank you guys,

Unfortunately my camera is so bad that sometimes the pictures get distorted, I did not notice that until you pointed that out. I guess I need to take another picture of this tonight after I get new batteries..

Well tonight I pulled plugs from the first silicon molds I made with my new Vacuum degasser, and wow, let me tell you, the difference is incredible!

To those interested in the kit, the reason I havent posted any new ones for sale is because you may as well wait for me to finish the last 2 molds.. These parts are going to be much better! I will post pics of the new VTOL front nacelle parts tomorrow (i need to wait a full 48 hours for mold cure) but the kit is going to be much higher quality. Also I have developed a new foam-core PVC resin hull technique that will be a higher quality hull while still using the same 60 ounces of resin, but it will be a much nicer hull.

The investment of a vacuum chamber (while a bit expensive) is still well worth the investment!!!! and now I can mold parts for other people if they need help on something...

I will post a completely remolded Starboard nacelle tomorrow pm Front, center section and rear corrugated part., The lines are so much crisper, and I have the correct angle now on the forward VTOL jet... actually I am very pleased with it..and you will be much happier with this redo in your kit

Interesting to know degassing makes such a big difference for you. It's something I've considered trying, particularly having found an enormous improvement when I invested in my pressure tank.

Actually I could not believe the difference it makes. I place 40 ounces of Silicon into the chamber, pulled pressure down to -30, the compound suddenly expanded to a huge "boiling" ball, and then collapsed... actually overflowing the large bowl it was in... The result in the mold was a flawless and more rigid silicon mold completely free of any tiny bubbles. They are well worth it if you can find a decent one. Mine is a MARVAC SCIENIFIC, and works just awesome.

My next project is going to be a large original ALIEN DERELICT on the same scale as the Nostromo kit.

Let me know if you'd like me to take on sculpting the Space Jockey to scale for that project.

Ok guys, here is the new starboard nacelle assembly with the new foamcore technique. The quality of the front VTOL part of the nacelle was the most critical, and let me tell you its quality is perfect. no flash, no bubbles, perfect details, perfect angle and grills on the VTOL and RETRO engines.... as han solo would say, "ya know sometimes I amaze myself" Laughing Laughing
sorry about the crummy camera, but I can assure you there are perfect little grill slats that cant really be made out due to the blurriness

But actually its because I actually invested on equipment and spent a lot of time on these parts. These kits will be better than the originals 25 years ago..and way more accurate.

This New Front part is just out of the mold 25 minutes ago before trimming ..
