Nevercallmebyneme Posted July 10, 2015 Posted July 10, 2015 Still it must be good to know that one of your parts has multiple uses right? Quote
Sariel Posted August 4, 2015 Posted August 4, 2015 I have finally found a moment to test Efferman's propellers. These: http://www.shapeways.com/product/5FGQ2E6CX/boat-propellor-5-studs I think they work pretty well. I have noticed that they generate some thrust sideways, but I guess that's inevitable. Most of the thrust is going in the desired direction, though, the speed is really good and I think there is less drag and smoother water flow than with regular Lego propellers. Quote
MaxSupercars Posted August 4, 2015 Posted August 4, 2015 Great video Pawel! I was waiting for it! But I have awaited more trust... Try to gear it up! I have awaited something like this: Max... Quote
Imanol BB Posted August 4, 2015 Posted August 4, 2015 Hi, what about to make a cover for thems to concentrate the thrust? (sorry if they already exist) Quote
Sariel Posted August 4, 2015 Posted August 4, 2015 The cover would probably help a bit if it was very smooth. But I don't see any way to make it smooth with LEGO. A 3D-printed cover, perhaps? The video Max linked shows larger propellers, I think. The size of a propeller has huge impact on how much thrust you get, especially since it's not always faster = better. All propellers are efficient within certain speed ranges and above certain speed they just don't get any more effective. Quote
Imanol BB Posted August 4, 2015 Posted August 4, 2015 (edited) i think this would be amazing for lego boats: , but, it would be almost impossible to recreate with lego but its maybe possible with 3D printed parts (however its very hard too). Edited August 4, 2015 by ImanolBB Quote

They are nicer, smaller and designed for opposite direction to zero the vibrations... I have geared up the simple propellers on my video and archieved very good trust... On video is state before gearing up... Max... Edited August 4, 2015 by MaxSupercars Quote
gevans12 Posted August 5, 2015 Posted August 5, 2015 Effe, have your tried your new outrigger parts on the Arocs set yet and how well do they look and function in comparison to the current outrigger setup? How would you motorise the larger one? Thanks Quote
efferman Posted August 8, 2015 Author Posted August 8, 2015 i have them, and they have the right size, but on the place where iam be i had not the right and enough parts to integrate them Quote
SNIPE Posted September 10, 2015 Posted September 10, 2015 Can you perhaps do a 5x5x4 (5 long 5 wide and 4 tall (4 tall in bricks) slope corner piece that would go in here: I need this for my alien base, I'd need 10 of the corner pieces to make it the ramps look complete Quote
JanGroen Posted September 11, 2015 Posted September 11, 2015 Hello Efferman, is it possible to make a design for 2 or 3 crane arm sections (which can slide in each other) and who can be extended by the new 1x11 pneumatic cilinder? Something like the black parts on the pictures: Quote
efferman Posted September 13, 2015 Author Posted September 13, 2015 Jan, iam working on something, but actually there is no time for inventor knuckleboom by Michael Wirth, auf Flickr snipe, it is surely possible to design a part like this, but you would have to paint them. Gevans, the outrigger pieces are working, but i have to change some small points. and like written above, there is actually no time for inventor Quote
JanGroen Posted September 13, 2015 Posted September 13, 2015 Painting is no problem . Is there an attachment possiblility for the new 1x11 pneumatic pistons on the crane sections? Quote
efferman Posted September 13, 2015 Author Posted September 13, 2015 The final parts will have the mounting points. Quote
Dafgek81 Posted September 13, 2015 Posted September 13, 2015 How many sections van by placed in each other? Quote
efferman Posted September 13, 2015 Author Posted September 13, 2015 The goal is 3 movable sections Quote
JanGroen Posted September 13, 2015 Posted September 13, 2015 The goal is 3 movable sections Let me know when your finished ;). Quote
TheItalianBrick Posted September 13, 2015 Posted September 13, 2015 I don't want to be controversial but let me say; where will end up if we start to design custom parts? It won't be anymore a LEGO thing, but simply a 3D printed toy! Custom parts eliminate the fun and the challenge of designing and bulding a LEGO MOC, there are plenty of ways to design a 3/4 sections boom. Quote
D3K Posted September 13, 2015 Posted September 13, 2015 I don't want to be controversial but let me say; where will end up if we start to design custom parts? It won't be anymore a LEGO thing, but simply a 3D printed toy! Custom parts eliminate the fun and the challenge of designing and bulding a LEGO MOC, there are plenty of ways to design a 3/4 sections boom. Start to design? It has been going on for quite a while, and a lot of people seem to appreciate it. So far the main products seem to be useful parts that allow for functions and aestetics not possible with Lego. And by not possible, I mean within the desired size and or strength. Building a 3/4 section boom that has good strength, looks and scale is not an easy feat. I know you've been working on something you say will be the most awesomest Technic truck crane ever, but so far you haven't shown anything that convinces me But each to his/her own. Some are more purist than others Quote
TheItalianBrick Posted September 13, 2015 Posted September 13, 2015 DK3 i know it's been a while, but one thing is to design a specific pin or another small part, one thing is to design a whole boom with sections! It won't look like a Lego thing. Effernam made those really nice leaf springs, I do made the same using only Lego parts and they work perfectly having also a differential for 8X8 trucks! About my crane, it doesn't convince you simply because I showed so little! Unfortunately I was waiting for new parts to complete them, but the early prototypes work week well and trust me are impressive! When finished I'll show you and hopefully I'll convince you and impress you too! Anyway I'm a purist so of course I tend not to like custom parts! But it's my opinion...just this! Quote
z3_2drive Posted September 13, 2015 Posted September 13, 2015 The 3D printed parts are not really pretty (grainy or colors that never perfectly match lego) and I like them when they are used to explore an entirely new idea, not to make something easier. For example, I recently got a couple female ball gear CV joint counterparts (to fit the ball gears like in 8880 supercar) as a substitute to U-joints. Not because it's easier but because it simply won't work any other way, every single u-joint at the scale i'm building in WILL break with 2-4 buggy motors, either right away or after some time. So I get these to try and see if they will survive the strain. I will agree, simply making parts for easy solutions when lego solutions exist, takes the fun out of finding out purist solutions, but when there is none and the custom parts explore new levels of performance/function it's nice to see it. And of course MOCs using non lego parts are labelled as such, can't be used in contests etc, so it's just personal interest. I understand both opinions. Also makes me wonder if Lego will make new parts similar to the ones people design, such as bringing back CV joints using the old ball gears! It's so much stronger than a U-joint and works more smoothly! Quote
TheItalianBrick Posted September 13, 2015 Posted September 13, 2015 True, but I think sometimes we pretend too much from Lego and we missunderstand the meaning of Lego. When you mention 2-4 buggy motors you probably better looking at RC model made out of metal. After all Lego it's not about performances ( high speed cars). Often I see people trying to make cranes able to lift lots of kilograms using iron parts as counterweight, why not simply design it to display their own beauty?! Anyway we do share opinions and we do have different tastes! Quote
z3_2drive Posted September 13, 2015 Posted September 13, 2015 I would, but man it is expensive, and I have other hobbies I spend money on, so I work with what I have now It's fun seeing how far you can push Lego, and you can use the same parts to make completely different things. I am reaching the end with my last few projects, though, and my current project will be the first of mine to use a printed piece. I guess I might move on, but that'll be a few hundred dollar investment and I'm not selling my Lego! On one hand, I love seeing people push the limits, and on the other, I love seeing purist MOCs using very creative solutions and fine aesthetics , including yours. Quote
Edwin Korstanje Posted September 13, 2015 Posted September 13, 2015 Great discusion guys , but this topic is about Efferman's custom parts . I think that you can better make a new topic for this discusion Quote
