  1. Thanks, interesting. But I definitely need to ditch the tube due to the weight tilting the base.
  2. A scissors lift would be great, but it requires a lot of math and 3D printing (not my skill set).
  3. Happy 2019 everyone. I'm trying to raise a 1/72 Prometheus Launch Elevator for my next project. This is a prototype to test the mechanics before shifting to a styrene diorama. The setup: - 9v battery with N20 long shaft 55mm motor at 150RPM. - I am using a tube to give support on the opposite side. The Results: - It is able to lift 300g, which is what I need for the 1/72 valk and electronics base - The styrene tube balance is giving friction. - There is some friction from the thread stabilizer hole in the wood block, which I think can be solved with a steel nut instead of the wooden hole. - There is a wobble on both sides of the lift, which pressure from my finger is not steadying The Possible Solutions: - I don't think a spring will help on the thread side because pressure support from my finger is not reducing the wobble. And the spring will only compress so much, so I will lose a part of the lift action. - I am thinking to replace the styrene tube with a second long thread motor to reduce the friction and balance. However, I don't know if I can parallel two motors with two separate sets of limit switches. Each motor needs its own limit switch in case they are out of synch and need some extra rotation to reach the limits evenly on both sides. (@Mechtech, can this be done?) - Possibly increasing the no load RPM from 150 to 300RPM. Any feedback or suggestions appreciated.
  4. Looks awesome! So how can we make it less risky? I would love to have one.
  5. Just my opinion, but the signal needs to be more elongated, and the signal arm needs to be wider.
  6. The new dimensions are looking good. The v1 traffic signal also needs some work I think.
  7. How do you plan to do the chipping? Paint and sponge should do it. I would like to see it posed with a 1/72 Valk when you're done. Meanwhile, he is cute and extremely powerful. Color scheme by wife and daughter.
  8. Thanks Mechtech, I reviewed your images, but I have no idea how that spring clutch works. Could you provide some leads for me to study to understand it? And oh my, look what this guy did. How the heck is that lever raising the ramp? Can't figure it out.
  9. Is that what it's called? Yes. A half revolution in either direction will give a nice effect. The drawing shows a 6mm micro stepper which doesnt require limit switches to fit in the leg. Unfortunately, I haven't been able to get any torque out of micro steppers yet. I think that some specific stepper driver boards may increase the torque, but not sure yet.
  10. A concept I'm working on.
  11. Ahhhhh, it's nice to be among my brethren.
  12. Interesting. But I suspect you had Nadia on TV. Correct or no?
  13. Well, I'm not a perfectionist. We can use those scale kits and call it fan fiction! The USS Eisenhower has that angled launch deck which kinda looks like the Prometheus,
  14. Thx Mechtech. Actually I've been reviewing your build for ideas. Your Daedalaus was a major influence in getting me into electronics. (FYI, your entire video is blocked in my country by WMG.) BTW, what would be the closest real world aircraft carrier model kits that could be used as a basis for scratching a Prometheus? Anyone know what the Prometheus deck and bow were based on? So how many Macross fans are there in Denmark? Really enjoying everyone's 1/20 progress around the web.
  15. She's CG? No no no. I have a sinking feeling about this. Lets hope for the best anyway.
  16. Leave a note, "Dear kids, this stuff is worth a lot of moolah on Ebay. Best wishes, Dad."
  17. Well, I've got a fun 1/72 Macross project in mind, if you're up to a team build. I need to raise that platform with about 200g of weight, and raise those blast deflectors. I've got most of the parts ready on my bench. Just slowed down by the steppers research, though I might end up using DC motors instead.
  18. Interesting. Do you know if the non-geared type get damaged if they keep rotating at a hard stop?
  19. That's some fine "backpack" research there .
  20. I built that same kit back in 1989 or 90. At the time I didn't understand kits, so I was frustrated that it needed painting and I glue parts that I should not have. I hated the thing, especially since I was a "Perfect Transfromation Snob" ahead of my time. This kit and the V1 Yamato 1/60 , pushed me away from Macross collecting for about a decade until the Perfect Transformation V2s came out. But looking back on it now after years of experience, I can say that it is a solid and great classic kit, especially if you love the old school designs. And I can add that in comparison, the modern transformable Bandai 1/72 is not good for anything except scrap parts. Build it, paint it, weather it, enjoy it. And share your progress
  21. Hee hee hee! So cute.
  22. valkyriepm, really nice weathering on that valk. I've been watching TONS of weathering tutorials. Now I need a subject to work with. Lt. Zombie, great scratch work there. I follow Ken Spriggs amazing detailed scratch work step-by-steps. Check it out! Mechtech, your lathe hobby continues to shock and awe me. As for me, I really like making my models move, so I have been studying how to control stepper motors with different Arduino driver boards and CNC conrol boards. I've never used steppers yet in my builds, only servos and DC motors so far. Since I have no programming knowledge, it's always months of study and research till I figure things out and find codes and wiring diagrams that work for me. I'm really excited about micro stepper because they don't need limit switches and are as small as 6mm. But so far I've found that micro steppers have too little torque to be useful in our models, unless I learn how to gear them up or design nearly weightless moving parts with low friction. Big Nema steppers are very powerful, but of course they don't fit in my scale models.
  23. OMG, I just realized you're Kye. I'm a huge fan of your work
