Paul B Technic Posted March 9, 2018 Posted March 9, 2018 I have just published my building process review of LEGO Technic set 42078 B Model (Mack LR Garbage Truck) http://paulstechnic.blogspot.com.au/2018/03/lego-technic-42078-b-model-build.html Quote
allanp Posted March 10, 2018 Posted March 10, 2018 It's amazing the difference sorted parts/numbered bags makes to the build. I built the Saturn V in under 4 hours, while 42069 took a few evenings and for all it's colour coding I couldn't find the hook till there was almost no parts left! Numbered bags are sooooooooooooooooooooooooooooooooooooooo much better than colour coding parts. Quote

Numbered bags are sooooooooooooooooooooooooooooooooooooooo much better than colour coding parts. Agree completely, but for my taste sets are to colorfull, so color coding is even more complex... But at least on Mack (unwanted) colors are hidden as much as possible Quote
Ngoc Nguyen Posted March 23, 2018 Posted March 23, 2018 @Shiva You can go to amazon de to see for yourself. At the current moment its price drops further to 105 EUR. It does sound like robbery... Quote
Shiva Posted March 24, 2018 Posted March 24, 2018 Ngoc Nguyen, I did that, when you mentioned the price drop earlier. Delivered it would be EUR 110,30 got me, sadly I can not afford a 2nd. I use to check prices with https://brickset.com/buy/amazon from time to time. Quote

Numbered bags are sooooooooooooooooooooooooooooooooooooooo much better than colour coding parts. I build my 42069 the past 2 evenings. I liked the end result, but really hated the build without numbered bags. Seriously, even just having the entire undercarriage labelled as "2" would have saved myself alot of annoyance on that build since that would pretty much half the amount of parts on my table. I too left the hook until I could find it later. So, good to see numbered bags return in 2018 for a set like this. Quote
paul_delahaye Posted April 15, 2018 Posted April 15, 2018 Anyone know the purpose of the spare steering wheel above the seats in the A model? I put it in as per the instructions, but I cannot see the point? Or was this just using a part which is needed in the B model? Quote
AVCampos Posted April 15, 2018 Posted April 15, 2018 The 2nd steering wheel is for the B-model. Quote

Magical Duck Posted August 2, 2018 Posted August 2, 2018 (edited) Hi, guys. After getting this model and building it over the last couple evenings, I noticed that there were a couple problems. - The steering system, while working just fine after connecting it and all that jazz, was experiencing issues with the finished model. When I try to steer left, some part of the linkage is getting caught on something, preventing me from turning it while it is driving on the ground (it is fine in the air) - The crane arms on my trailer are having issues with the container. The lower, large actuators work just fine, but the upper ones can hardly lift the (empty!) container, and there is a lot of grinding noise when I operate the gears. I built the gears as usual, trying to create the least amount of friction possible, yet they still grind and move very reluctantly. If anybody has any solutions, they would be welcome! EDIT: I also noticed another thing: both problems occured after installing part 4558692 gear bracket Does something about this part with the two 12T bevel gears cause a lot of friction?

Magical Duck Posted August 2, 2018 Posted August 2, 2018 (edited) Sorry, I couldn't figure out how to put in videos from flickr, they wouldn't play- so here is the link to the flickr page instead: https://www.flickr.com/photos/141573051@N03/with/42907982705/ Does anyone else have these issues? Edited August 2, 2018 by Magical Duck Quote
JonathanM Posted August 3, 2018 Posted August 3, 2018 The steering issue is definitely a problem. Not sure what it is, but definitely don't have that on mine. The trailer issue I'm not so sure - it is reasonably hard work for the mini LAs to lift the container, especially when the large LAs are at their lowest point as the U-joints are bending tightly then. Does it also happen when the large LAs are first fully extended before you move the mini LAs? Quote
conceitedguy Posted August 3, 2018 Posted August 3, 2018 I've also experienced that steering problem; all I can suggest is you ensure that the wheels are snugly pushed onto the axles and that everything involved in steering is secure Quote
Magical Duck Posted August 3, 2018 Posted August 3, 2018 @JonathanM, yes, even when the large ones are extended all the way, the mini LAs are struggling @conceitedguy, both wheels were pushed in, but upon tearing the front end apart, I found that the rear steering rack was not assembled properly. Thank you! Quote
JonathanM Posted August 3, 2018 Posted August 3, 2018 My mini LAs are reasonably hard to operate (i.e. quite a lot of torque on them) but they are smooth - i.e. no gear grinding or weird sounds when operating. Are your universal joints aligned? i.e. the orientation on the axles should be the same, else it leads to uneven rotation, particularly when they're at large angle under load like these ones. I seem to recall the first crane (rear) in the instructions had the universal joints aligned correctly, but the second (front) had them incorrect in the instructions (it wouldn't normally make all that much difference, but in this case it could be it?) Only other thing is just making sure everything is as little friction as possible, but it seems you've already done that... Quote
Magical Duck Posted October 11, 2018 Posted October 11, 2018 Grohl666 finished his Mack Granite C model: (can't remember where i saw the WIP, so I posted it here) Quote
mpj Posted October 11, 2018 Posted October 11, 2018 Beautiful! What scale is the Mack, more or less? 1:20 / 1.21? Quote
Aleh Posted October 12, 2018 Posted October 12, 2018 Brilliant alternative model! Like the adjustable axle most of all! Quote

leinaud Posted October 15, 2018 Posted October 15, 2018 Too bad there won't ever be instructions (i think?); that would almost make me buy a third Mack just to have all three together on a shelf like in the video! Quote

Lucas11 Posted May 27, 2019 Posted May 27, 2019 can you show use how to build the Blue container Quote
