Thank you Edited December 27, 2019 by sirslayer update Quote
emielroumen Posted December 27, 2019 Posted December 27, 2019 Looks great! Judging the photos, it looks like the rear axle and suspension is not properly fixed in place. Is it stable enough? Quote
sirslayer Posted December 27, 2019 Author Posted December 27, 2019 @emielroumen thank you and yes the rear suspension is stable.. The picture I've uploaded does look like its uneven but its just the snow causing the uneven surface. Ill upload a video when I get some time.. I have a video of the suspension before I locked the rear independent from limited live axle just to rear independent.. The reason ive done is that before the rear suspension was just a mirror of the front suspension and the issue was that the body roll was to sensitive. Moving the springs down to per wheel hub kept the rear suspension without the limited live axle support .. I do have a video with the old rear axle setup and It was just the body roll was the concern.. Quote
sirslayer Posted December 27, 2019 Author Posted December 27, 2019 (edited) Here are some more pics of the rear and front and even the rear hub!! One thing I learned is that the number 0937 spells Lego when you flip it upside down and man!! I need to clean up the dirt off my model :( !!!

Great that it works fine in real life! Quote
sirslayer Posted December 27, 2019 Author Posted December 27, 2019 @emielroumen You are correct about the rear support!! It's a simple fix!! I would only apply the fix if I evered motorized my model ,(the contest doesn't allow it) sliding a 5x7 frame between the diff and the "wishbone arms" would give it the extra support.. the worst case scenario, the back wheel would move over just one stud over... Quote
sirslayer Posted December 29, 2019 Author Posted December 29, 2019 Just did a short video on some of the features of my model. I also added the 5x7 frame to support the axles from sliding around and a hood strut to keep the hood open .. In a weeks time i'll post more add on you can mount on my model.. please post any questions or concerns . Quote
sirslayer Posted December 29, 2019 Author Posted December 29, 2019 (edited) This is an example of my 2 speed hi/lo transmission. The transmission has an integrated center differential output and it only takes up 8 studs by 3 studs by 5 studs of space.. The motor input is at the top row represented by the gray color 16 tooth gear. Not to brag ... I weighted out all the axles and gears on a scale to insure a proper balance and fitness of my transmission design..

johnnym Posted December 29, 2019 Posted December 29, 2019 Nice pickup with a lot of functions (AWD, door locks, sliding front seats, adjustable side mirrors, openable tailgate, winch, etc.). That truck is a clear departure from the designs you presented earlier. The usage and placement of the old-style diffs is very interesting. Would you mind creating a digital model of the drive train? I like the front lights design very much - looks modern and harmonic with the wheel arches. Although the front window frame is a little bent at the top, it gives it an organic look. Hey, did you maybe miss the rear mirror there? I find the brush guard a little too massive, those axle/pin connectors are too thick IMO - similar to the roll bar in @Thirdwigg's pickup - but that's only my opinion. What parts did you use for the hood strut? I don't seem to know these parts. I assume you need the housing around the front and rear diffs for bracing them, but that could also make problems when going off-road. Imagine the truck crosses a rock that fits between front and rear wheels, depending on the height of the rock, the truck could get stuck more easily than with a design with more clearance there. But yeah, space is limited in that scale. Quote
sirslayer Posted December 30, 2019 Author Posted December 30, 2019 @johnnym Thank you and yes, I can create an digital layout of the drivetrain.. Just give me a day or two.. Oddly, this model was based off from my early designs and I do have the blue and red color fenders and believe me, the red fenders look great on this current model but the orange color Corvette issues still haunts me and the red color fenders are just like the Corvette orange fenders , i'll be safe and stay with the color black!! (Have I every mention to you, That the color technic black weighs less then the other technic colors).. The odd layout of the rear and front differential is to fit the into the 13 stud wide independent suspension and I manage to design a working model out of it.. This is new territory for the LEGO set 8081 challenge, If you ever done a Google search with the keywords "LEGO 8081 mod". You'll see at least 7 years + of some of the greatest mods for the 8081 and to be original on a mod design would be a challenge.. The front window on my mod had a major revamp due to a new function I wanted to use . the single bladed "windshield wiper" mechanics was to large and i'll use it on another project. The rear view mirror has a spot to be mounted and i haven't found the ideal brick.. the brush guard is just an option and the strut element is packaged on this LEGO set, https://brickset.com/sets/60107-1/Fire-Ladder-Truck . The 3 diff chassis is unique and I believe the huge gap on the bottom of the chassis between the axles can be filled with motors or even better, skid plates !! 60107-1: Fire Ladder Truck Lego Technic 8081 mod by victormendoza_jr, on Flickr Quote
sirslayer Posted December 31, 2019 Author Posted December 31, 2019 Holes, holes, holes everywhere. LEGO Technics models can have great mechanical functions in detail but at a cost of having unrealistic cosmetic appearance. A building technique called SNOT (Studs Not On Top) can be implemented on LEGO technic beams and lift arms. LEGO technic part # 4274 1/2 pins are one of the smallest technics elements.. and you can use these parts by inserting them onto your liftarms (or any technic hole) and using any Lego tiles of your color and size.. For example I'm using a black color 1x 9 tile, the tile you should be looking for are very thin and it can make any technic model into a Leader class creation..

(im still learning the program.) Ill have more coming soon.

sirslayer Posted January 23, 2020 Author Posted January 23, 2020 Some more photorealistic renders drawing from Studio 2.1 The render took a few hours and they real look good..

sirslayer Posted January 26, 2020 Author Posted January 26, 2020 The Black Widow on 68.8mm ?? tires, Wearing the rims and tires from Lego set 8682.. I never knew this set existed till I won the set on Ebay, last week!! Interesting model and how it compare in size. Next week I will do a comparison between the Black Widow and the Lego 8081 Extreme Cruiser. lego technic 8682 vs my 8081 mod by victormendoza_jr, on Flickr Quote
Maaboo the Witch Posted January 27, 2020 Posted January 27, 2020 The suspension on the front axle needs a rethink. Look at the yellow shock absorber. Quote
sirslayer Posted January 27, 2020 Author Posted January 27, 2020 @Maaboo35I found my model on the ground and I think my cat knock it over.. Very good observation !!! and yes a better solution is all ready on my Studio file. I haven't updated the physical model since I'm planning to to take apart my model to be used on the upcoming Eurobricks contest.. The advantage on using a 3d model is you never run out of parts!!!! So any more updates will be in digital format. IMG_20200127_043914703 by victormendoza_jr, on Flickr We both miss you, Vanessa!!! from Victor and Smudge Quote
sirslayer Posted January 31, 2020 Author Posted January 31, 2020 (edited) A quick comparison of the Lego 8081 front suspension vs Black Widow front suspension The Lego Technic 8081 original front suspension mod. This mod mimics the build and adds a wheel hub in a 13 wide frame. Not only it's supports an independent suspension setup with drive. The springs at max compression turns on the 2nd features that transform the independent suspension to limited live axle suspension with Max travel. 2.0 Exoskeleton release You can download the Black Widow 2.0 exoskeleton (new chassis) Studio file for free or just view it in 3d from Bricklink.com link below https://www.bricklink.com/v3/studio/design.page?idModel=122661 8081boss_Copy by victormendoza_jr, on Flickr Edited February 8, 2020 by sirslayer Quote
sirslayer Posted February 3, 2020 Author Posted February 3, 2020 (edited) Black Widow 2.0 Exoskeleton Can you tell the difference between 2.0 vs 8081!!?? Will the real slim shady stand up!! Edited February 8, 2020 by sirslayer Quote
sirslayer Posted February 8, 2020 Author Posted February 8, 2020 The Black Widow 2,0 is my 2021 AD model which features all the functions from version 1.0 plus 4 wheel steering and new compact chassis that can be used as a direct replacement of the Lego set 8081 chassis and keeping the original body style of a v4 cruiser 2 door off road vehicle with independent suspension and big balloon tires. I believe this is a legit mod for the Lego set 8081 this is my best 8081 chassis mod ever!! 8081boss_Copy by victormendoza_jr, on Flickr Bricklink link https://www.bricklink.com/v3/studio/design.page?idModel=122661 Quote
